Meeting the energy and nitrogen (N) requirements of high\uffe2\uff80\uff90performing ruminants at the same time as avoiding digestive disturbances (i.e. rumen acidosis) is a key priority in ruminant nutrition. The present study evaluated the effect of a cereal ammoniation treatment, in which barley grains are combined with urea and enzymes that catalyze the conversion of urea to ammonia to optimize rumen function. Twelve rumen cannulated sheep were randomly divided into two groups and fed a diet containing 60% of ammoniated barley (AMM) or untreated barley supplemented with urea (CTL) to investigate the impact on rumen fermentation and feed utilization.
RESULTSAMM had higher total N content and effective rumen degradable N than untreated barely. AMM sheep had a consistently higher rumen pH throughout the day (6.31 versus 6.03) and tended to have a lower post\uffe2\uff80\uff90prandial ammonia peak and higher acetate molar proportion (+5.1%) than CTL sheep. The rumen environment in AMM sheep favored the colonization and utilization of agro\uffe2\uff80\uff90industrial by\uffe2\uff80\uff90products (i.e. orange pulp) by the rumen microbes leading to a higher feed degradability. AMM sheep also had higher total tract apparent N digestibility (+21.7%) and urinary excretion of purine derivatives (+34%), suggesting a higher N uptake and microbial protein synthesis than CTL sheep.
CONCLUSIONThe inclusion of AMM in the diet of ruminants represents a valid strategy for maintaining rumen pH within a physiological range and improving N utilization by the rumen microbes, which could have positive effects on the health and productivity of animals in intensive production systems. These findings warrant further studies under conventional farm conditions. \uffc2\uffa9 2021 The Authors.

Paddy soil has been known to have strong denitrifying activity, but the denitrifying microorganisms responsible for fertilisers in paddy soil are not well known. The objective of this study was to explore the impacts of 17\uffe2\uff80\uff90year application of inorganic and organic fertiliser (rice straw) on the abundance and composition of a nosZ\uffe2\uff80\uff90denitrifier community in paddy soil. Soil samples were collected from CK plots (no fertiliser), N (nitrogen fertiliser), NPK (nitrogen, phosphorus and potassium fertilisers) and NPK + OM (NPK plus organic matter). The nitrous oxide reductase gene (nosZ) community composition was analysed using terminal restriction fragment length polymorphism, and the abundance was determined by quantitative PCR.
RESULTS: Both the largest abundance of nosZ\uffe2\uff80\uff90denitrifier and the highest potential denitrifying activity (PDA) occurred in the NPK + OM treatment with about four times higher than that in the CK and two times higher than that in the N and NPK treatments (no significant difference). Denitrifying community composition differed significantly among fertilisation treatments except for the comparison between CK and N treatments. Of the measured abiotic factors, total organic carbon was significantly correlated with the observed differences in community composition and abundance (P < 0.01 by Monte Carlo permutation).
CONCLUSION: This study shows that the addition of different fertilisers affects the size and composition of the nosZ\uffe2\uff80\uff90denitrifier community in paddy soil. Copyright \uffc2\uffa9 2011 Society of Chemical Industry

Rootstocks are widely used to enhance plants resistance to drought stresses. This study determined influence of rootstock on drought responses in 1\uffe2\uff80\uff90year\uffe2\uff80\uff90old \uffe2\uff80\uff98Gale Gala\uffe2\uff80\uff99 apple trees grafted onto Malus sieversii or M. hupehensis.
RESULTS: Choice of rootstock resulted in differential response to drought stress. Specifically, M. sieversii caused less drought\uffe2\uff80\uff90induced reduction in relative growth rate, biomass accumulation, leaf area, leaf chlorophyll content, relative water content, photosynthesis rate and maximum chlorophyll fluorescence yield but greater increase in whole\uffe2\uff80\uff90plant water use efficiency compared to M. hupehensis. Secondly, compared with M. hupehensis, M. sieversii caused less drought\uffe2\uff80\uff90induced accumulation of reactive oxygen species but more increase in activities of antioxidant enzymes. In addition, xylem sap abscisic acid concentration was greater in trees grafted onto M. hupehensis than in those grafted onto M. sieversii under drought stress.
CONCLUSION: \uffe2\uff80\uff98Gale Gala\uffe2\uff80\uff99 trees' response to drought stress was associated with the rootstock's genotype onto which it was grafted. Trees with M. sieversii as rootstock are more drought resistant than trees with M. hupehensis as rootstock, which suggests that M. sieversii can be widely used as rootstock in arid and semi\uffe2\uff80\uff90arid regions.

The trial is a long\uffe2\uff80\uff90term field experiment which divides conventional and organic agriculture into component pest\uffe2\uff80\uff90control and soil treatment practices. We hypothesised that management practices would affect soil ecology and used community level physiological profiles, microbial and nematode counts, and denaturing gradient gel electrophoresis (DGGE) to characterise soil microbial communities in plots used for onion (Allium cepa L.) cultivation.
RESULTSMicrobial activity and culturable bacterial counts were significantly higher under fully organic management. Culturable fungi, actinomycete and nematode counts showed a consistent trend towards higher numbers under fully organic management but these data were not statistically significant. No differences were found in the fungal/bacterial ratio. DGGE banding patterns and sequencing of excised bands showed clear differences between treatments. Putative onion fungal pathogens were predominantly sequenced under conventional soil treatment practices whilst putative soil suppressive bacterial species were predominantly sequenced from the organic pest\uffe2\uff80\uff90control treatment plots.

This study investigated the effects of burial of straw on water percolation, nitrogen loss by leaching, crop growth and yield. Greenhouse mesocosm experiments were conducted over the course of three simulated cropping seasons in a rice1\uffe2\uff80\uff93wheat\uffe2\uff80\uff93rice2 rotation.
RESULTSGreater amounts of straw resulted in more water percolation, irrespective of crop season. Burial at 20 and 35\uffe2\uff80\uff89cm significantly reduced, but burial at 50\uffe2\uff80\uff89cm increased nitrogen leaching. Straw at 500\uffe2\uff80\uff89kg\uffe2\uff80\uff89ha\uffe2\uff88\uff921 reduced, but at 1000\uffe2\uff80\uff89kg\uffe2\uff80\uff89ha\uffe2\uff88\uff921 and at 1500\uffe2\uff80\uff89kg\uffe2\uff80\uff89ha\uffe2\uff88\uff921 straw increased nitrogen leaching in three consecutive crop rotations.

CONCLUSIONSThis study suggests that N losses via leaching from the rice\uffe2\uff80\uff93wheat rotation may be reduced by the burial of the appropriate amount of straw at the appropriate depth. Greater amounts of buried straw, however, may promote nitrogen leaching and negatively affect crop growth and yields.

The nutrients, however, are mostly in organic form and must be mineralized to make them available to plants. The objective of this work was to establish a usage guideline for the compost by studying its mineralization dynamics. Also, the release of inorganic N and C from soil fertilized with the compost was monitored and modelled.C and N were released throughout the assay, to an extent significantly dependent on fertilizer rate. Mineralization of both elements fitted a first-order exponential model, and each fertilizer rate required using a specific fitting model. An increased rate favoured mineralization (especially of carbon). After 90 days, 2.3% of C and 7.7% of N were mineralized (and 23.3% of total nitrogen made plant available) with the higher rate.C mineralization was slow because organic matter in the compost was very stable. On the other hand, the relatively high initial content in mineral N of the compost increased gradually by the effect of mineralization. The amount of N available would suffice to meet the requirements of moderately demanding crops at the lower fertilizer rate, and even those of more demanding crops at the higher rate.", "keywords": ["Crops", " Agricultural", "2.

We investigated the impact of cover crop management methods on maize growth performance and assemblages of AMF colonizing maize roots in a field trial. The cover crop treatments comprised Italian ryegrass, wheat, brown mustard and fallow in rotation with maize.
RESULTSThe diversity of AMF communities among cover crops used for maize management was significantly influenced by the cover crop and time course. Cover crops did not affect grain yield and aboveground biomass of subsequent maize but affected early growth. A structural equation model indicated that the root colonization, AMF diversity and maize phosphorus uptake had direct strong positive effects on yield performance.
CONCLUSIONAMF variables and maize performance were related directly or indirectly to maize grain yield, whereas root colonization had a positive effect on maize performance. AMF may be an essential factor that determines the success of cover crop rotational systems. Encouraging AMF associations can potentially benefit cover cropping systems. Therefore, it is imperative to consider AMF associations and crop phenology when making management decisions. \uffc2\uffa9 2017 Society of Chemical Industry

In this study, forage production in grazed and protected plots and grazing responses of small ruminants in cleared (25% shrub cover), slashed (34% shrub cover) and not treated (control, 55% shrub cover) kermes oak (Quercus coccifera L.) shrublands were compared during the spring seasons of 1992, 1993 and 1994. The alterations in shrub density were done in October 1991 and pastures remained ungrazed until spring of 1992. Clearing and slashing of shrub vegetation resulted in higher amounts of available herbaceous forage and useable browse. At the end of the growing season, averaged across years, herbaceous biomass was generally two to three times higher in the treated shrublands than in the control; also, browse biomass was slightly less (1,078 vs 1,533 kg/ha) but easily accessible because of the open structure and the lower height of the sprouting shrubs. There were generally no grazing response differences between the cleared and slashed pastures. However, grazing animals (sheep and goats) had a higher bite rate (bites/min; P \u2a7d 0.05) in the treated pastures than in the control. Levels of crude protein in the forage selected by animals were higher (P \u2a7d 0.05) in the treated pastures than in the control. Animals in the improved pastures maintained diets that were significantly more digestible (53.5%) than those in the control pasture (48.5%). Neutral detergent fibre and lignin contents of animal diets were similar in the improved pastures but lower (P \u2a7d 0.05) than those of the control. It is concluded that removing of woody vegetation in Mediterranean shrublands results in increased forage production (available herbage and useable browse) and improved forage quality and availability for small ruminants.", "keywords": ["2.

Little is known about the effect of increased grazing intensity on nitrogen (N) and carbon (C) cycling and losses from these hill country grazing systems, nor of the effect of micro-topography on N and C pools and fluxes. A three year grazing trial was conducted to gather information on the effect of an increase in grazing intensity on soil chemistry and N and C leaching in three distinct micro-topographical classes. In this temperate environment, micro-topography was the dominant influence on annual net herbage accumulation, soil chemistry and N and C leaching. Net herbage accumulation was two- and five-fold greater on low ( 25\u00b0) slopes (14.6, 7.8, and 2.9\u00a0t\u00a0DM\u00a0ha \u22121 \u00a0yr \u22121 , respectively). Low slope soils had generally higher concentrations of phosphorus and N and C species compared to soils on medium and high slopes. Nitrogen leaching was greatest in low compared to medium slope areas: three-year mean estimates of annual leaching were 80 vs . 7\u00a0kg inorganic N\u00a0ha \u22121 , and 40 vs . 8\u00a0kg dissolved organic N\u00a0ha \u22121 , respectively. Per ha estimates of inorganic N leaching in this landscape (where low, medium and high slopes occupy 10, 60 and 30% of the land area) are 15\u00a0kg\u00a0N\u00a0ha \u22121 if we make the assumption that high slopes leach as much inorganic N as medium slopes, or 12\u00a0kg\u00a0N\u00a0ha \u22121 if it is assumed that high slopes do not leach at all. The significant effect of slope on parameters measured is a reflection of micro-topographical influences on livestock grazing, resting and excreting patterns. Estimates of annual dissolved organic C leaching were not significantly different between low and medium slopes (185 vs . 132\u00a0kg\u00a0C\u00a0ha \u22121 , respectively). Grazing intensity, at the two contrasting grazing pressures employed (annual mean standing biomass of 1900 vs . 1475\u00a0kg\u00a0DM\u00a0ha \u22121 ), had no significant impact on the variables measured in this three year study, demonstrating the robust nature of these grazing systems in the short-term.

The experimental site was located 80 km east of Perth, Western Australia. Some sheep were maintained on the pasture for 4 yr and other low selenium sheep were introduced at various times over 5 yr to distinguish carryover effects within the sheep from those in the pasture/soil. A single application of the slow-release Se fertilizer based on BaSeO4 at 10 g Se ha\u22121, maintained adequate Se concentration in the blood to prevent subclinical Se deficiency for 4 yr. A single application of Na2SeO4 fertilizer applied at the same rate was effective for only 15 mo. The difference in solubility between the quick (Na2SeO4) and the slow-release form (BaSeO4) of Se allows alternative management strategies. The quick-release form could be used annually in smaller quantities (2\u20133 g Se ha\u22121) where pastures are rotated with crops that do not require Se. The slow-release form at higher application rates (10 g Se ha\u22121) is more suited to long-term pasture areas which would therefore require infrequent applications of Se. Slow-release Se fertilizers that are controlled by dissolution are well adapted to the mediterranean environment where crop growth is restricted to the cool wet winter months and there is very little soil moisture or plant growth during the summer.", "keywords": ["2.

Consequences of methodological choices and data sensitivity on CFPs of feed ingredients were explored to improve comparison and interpretation of CFP studies. Methods and data for emissions from cultivation and processing, land use (LU), and land use change (LUC) were analyzed. For six ingredients (maize, wheat, palm kernel expeller, rapeseed meal, soybean meal, and beet pulp), CFPs resulting from a single change in methods and data were compared with a reference CFP, i.e., based on IPCC Tier 1 methods, and data from literature. Results show that using more detailed methods to compute N2O emissions from cultivation hardly affected reference CFPs, except for methods to determine leaching (contributing to indirect N2O emissions) in which the influence is about -7 to +12 %. Overall, CFPs appeared most sensitive to changes in crop yield and applied synthetic fertilizer N. The inclusion of LULUC emissions can change CFPs considerably, i.e., up to 877 %. The level of LUC emissions per feed ingredient highly depends on the method chosen, as well as on assumptions on area of LUC, C stock levels (mainly aboveground C and soil C), and amortization period. We concluded that variability in methods and data can significantly affect CFPs of feed ingredients and hence CFPs of livestock products. Transparency in methods and data is therefore required. For harmonization, focus should be on methods to calculate leaching and emissions from LULUC.

A field experiment was established on a moderately acidic yellow Kandosol and monitored over 5\u00a0years. Five perennial pasture species including lucerne (Medicago sativa L.), phalaris (Phalaris aquatica L.), chicory (Cichorium intybus L.), tall fescue (Festuca arundinacea Schreb.) and cocksfoot (Dactylis glomerata L.), were sown in monocultures with and without 2.9\u00a0t/ha lime. Both lucerne and phalaris were more persistent than chicory, tall fescue and cocksfoot under severe drought, despite both being considered sensitive to soil acidity. Surface liming increased the soil water deficit by up to 27\u00a0mm at 0.75\u20131.65\u00a0m under perennial pastures compared to unlimed treatments, despite lime having no physical presence at that depth. Lime increased lucerne, phalaris and cocksfoot cumulative herbage biomass by 150, 30 and 20\u00a0%, respectively, but had no significant effect on chicory or tall fescue biomass. The two most acid-sensitive species, lucerne and phalaris, were more resilient under drought despite the acidic nature of the soil.

At ages of 5, 9 and 11 months, enteric methane was measured in open circuit respiratory chambers along with feed intake and excretion. Ruminal fluid was collected at slaughter. Slurry-derived methane was determined while stored at 14\u00a0\u00b0C and 27\u00a0\u00b0C for 15 weeks. Exchanging maize for grass silage increased enteric methane only on one occasion. Total system methane emission was similar between grass- and maize-silage fed bulls. Tannin decreased methane by up to 36% and, most importantly, this suppression persisted throughout the entire experiment. Tannins did not alter slurry-derived methane. Enteric methane conversion rate and methane conversion factors in slurry were always below the IPCC default values. Grass silage increased fibre digestibility and numbers of total and cellulolytic Bacteria. The study demonstrated a long-term efficacy of acacia tannin in mitigating methane.

Four rumen-fistulated wethers were allocated in a 4 \u00d7 4 Latin square design. Nitrate (1.3 g NaNO3/kg 0.75 of body weight (BW)), with and without 1-4 galacto-oligosaccharides or nisin was administered into the rumen through a fistula 30 min after the morning meal as a single dose, whereas, 1-4 galacto-oligosaccharides (20 g per day) or nisin (3 mg/kg 0.75 of BW per day) was supplemented by sprinkling it onto the feed. Physiological saline was used as control treatment. When compared to saline, nitrate alone markedly lowered rumen methane production and caused a marked accumulation of rumen and plasma nitrite, and formation of blood methemoglobin consequently reduced oxygen consumption, carbon dioxide production, and metabolic rate. As compared to nitrate alone, simultaneous administration of nitrate with 1-4 galacto-oligosaccharides or nisin lowered the concentration of rumen and plasma nitrite and methemoglobin, while keeping rumen methanogenesis at a low level. A relatively higher rate of oxygen consumption, carbon dioxide production, and metabolic rate of sheep given nitrate plus nisin was observed versus that in sheep given nitrate alone. Therefore, an appropriate combination of nitrate with 1-4 galacto-oligosaccharides or nisin might be effective manipulators to abate rumen methanogenesis without nitrate intoxication in ruminants. \u00a9 2004 Elsevier B.V.

The concentrations of total VFA decreased by substitution of sorghum-sudan with alfalfa in both species, but the magnitude of the reduction was smaller in alpacas (\u221217%) than in sheep (\u221234%). The molar proportions of acetate and BCFA were higher, whereas those of butyrate were lower in alpacas than in sheep with similar proportion of propionate as well as ratio of acetate to propionate between alpacas and sheep. Replacing sorghum-sudan with alfalfa in the diet reduced the ratio of acetate to propionate due to the reduced proportion of acetate and increased proportion of propionate. Ammonia N concentration was about 28% lower in alpacas than in sheep, with no difference between the forages. Redox potential, forestomach pressure, osmolality and methane production were overall lower in alpacas than in sheep. There were no interactions of species with forage source on digestibilities in the total tract. The species had minimal effect on the total digestibilities of nutrients but digestibilities of fibre were lower with alfalfa than with sorghum-sudan diet.

RFI has been shown to be linked with a reduction in CH 4 emissions in studies that used grain based diets. Our study quantified CH 4 emissions from 48 Angus cows selected based on estimated breeding values (EBV) for extremes in RFI. These EBV were based on a post weaning RFI test conducted at the Western Australian Department of Agriculture and Food Vasse Research Centre. Two groups of cows with divergent RFI were used being: 25 high RFI ( i.e. , HRFI, low efficiency) cows with an EBV of 0.68\u00a0\u00b1\u00a00.220\u00a0kg/d, and 23 low RFI ( i.e. , LRFI, high efficiency) cows with an EBV of \u22120.69\u00a0\u00b1\u00a00.335\u00a0kg/d. Methane emissions were measured under grazing conditions in a Western Australian annual pasture production system using the Open Path Fourier Transform Infrared Spectrophotometer (OP-FTIR) technique. A group average emission rate was obtained for the two RFI lines of cows. Each group was measured separately over a two 6\u00a0d periods being in the summer when the cows were pregnant and grazing annual pastures of a low dry matter (DM) digestibility of 550\u00a0g/kg, and in the winter when the cows were nursing calves and grazing annual pastures with a high DM digestibility of 810\u00a0g/kg. It was hypothesised that LRFI cows would produce less CH 4 when grazing both high and low quality pastures. When pregnant and grazing low quality pastures, both groups of cows produced similar amounts of CH 4 /day (0.26\u00a0\u00b1\u00a00.013 versus 0.26\u00a0\u00b1\u00a00.018\u00a0g CH 4 /kg of liveweight (LW) for LRFI and HRFI cows respectively. While nursing calves and grazing high quality pastures, there was a difference (P 4 emissions between the LRFI and HRFI cows of 0.34 CH 4 \u00a0\u00b1\u00a00.017 versus 0.46\u00a0\u00b1\u00a00.023\u00a0g CH 4 /kg LW). The hypothesis that LRFI cows produce less CH 4 is not supported by results for these cows grazing low quality summer pasture, but it is supported when grazing high quality winter pastures. Results indicate LRFI cattle may have the potential to contribute to reduced CH 4 emissions under grazing systems when provided with a high nutritional quality pasture source.

Few recent studies have examined medium or long term effects of methanogen inhibitors on rumen functional parameters and development of resistance to them. The aim of our study was to investigate medium term effects of a potent methanogen inhibitor on methanogen populations using molecular techniques and rumen function. Six rumen fistulated cows were divided into two groups and allocated to control and chloroform treatment and fed at a fixed rate of 8.4\u00a0kg\u00a0dry matter (DM)/cow/d. After 7\u00a0d of acclimatization, treatment cows were dosed daily with 1.5\u00a0ml of chloroform in 30\u00a0ml of sunflower oil for 42 d, while control cows only received sunflower oil. Key indicators of rumen function monitored included rumen pH, rumen fill, apparent feed digestibility, apparent rumen digesta retention time, total protozoa numbers, and volatile fatty acid (VFA) and NH3 concentrations. Methane emissions were monitored using the SF6 tracer technique, and methanogens using denaturing gradient gel electrophoresis (DGGE) and four clone libraries. Methanogens and acetogens were monitored in a single cow by most probable number culturing methods. Chloroform, a known inhibitor of methanogenesis, resulted in an immediate and dramatic decrease in CH4 emissions and methanogen numbers, with the effect being most pronounced 1\u00a0wk after the start of the treatment. Thereafter, CH4 emissions increased slowly, reaching 62% of pre-treatment levels by d 42. The effect on CH4 emissions was reflected by a near complete disappearance of DGGE bands associated with methanogens in treated cows. This response was particularly obvious for Methanobrevibacter species. There were no effects of chloroform on apparent rumen digesta retention time, apparent feed digestibility, pH, NH3 or rumen fill. Total protozoa numbers tended to increase during the study in both groups. Total VFA concentrations did not change with chloroform treatment, but the acetate:propionate ratio during the period of dosing was lower (P This article is part of the special issue entitled: Greenhouse Gases in Animal Agriculture \u2013 Finding a Balance between Food and Emissions, Guest Edited by T.A.

This study was designed to estimate repeatability and heritability of the CH4 emission trait in sheep, and to determine whether the ranking of sheep based on their CH4 emissions is maintained over a range of contrasting diets. A flock of 105 ewe lambs (10 months old) of a progeny testing program were screened for their CH4 yields (i.e., emissions/unit feed dry matter (DM) intake) when a molasses containing grass silage was fed at restricted intake (1.3\u00a0\u00d7\u00a0maintenance metabolisable energy requirements). Methane emissions were measured on a single day in respiration chambers over 4 measurement periods with 13\u201315\u00a0d between consecutive measurements (i.e., screening phase). Mean CH4 yield of lambs was 18.4\u00a0\u00b1\u00a00.38\u00a0g/kg DM intake during the screening phase, and estimates of repeatability and heritability for CH4 yield were 0.16 and 0.30, respectively. Methane yield in the screening phase was 7.9% higher for the high versus low ranked sheep (19.2\u00a0\u00b1\u00a00.18 versus 17.8\u00a0\u00b1\u00a00.26\u00a0g/kg DM intake). The 10 lowest (low rank) and the 10 highest (high rank) CH4 yielding sheep were selected and retained for further study. Two repeated measurements of CH4 yield were conducted, the first measurement while sheep were fed fresh cut perennial ryegrass pasture (grass), the second with the same sheep fed a 400:600 concentrate:forage (wheat grain:lucerne hay; fresh basis) pelleted diet (pellet). Repeated measurements revealed that rankings were maintained among diets, but that there was a CH4 rank\u00a0\u00d7\u00a0diet interaction for CH4 yield. When fed the grass diet, the high ranked sheep had 13% higher CH4 yield than the low ranked sheep, but when fed the pelleted diet, the high ranked sheep had 36% higher CH4 yield than the low ranked sheep. Emissions of hydrogen were only measurable when sheep were fed the pelleted diet. This study is the first to report that ranking of sheep for CH4 emissions is consistent among diets, although the magnitude of difference among the rankings was affected by diet, suggesting that among animal variation in CH4 emission could be exploited to breed animals for low CH4 emission.

The purpose of this experiment was to evaluate four dietary treatments designated as control (CON), brewers grains (BG), hominy meal and cold-pressed canola (HCC) and hominy meal only (HM) for their effects on CH4 emissions and milk production. Sixteen late lactation Holstein cows were used in pairs, in a double 4 \u00d7 4 Latin square experiment with the four dietary treatments fed as total mixed rations over 24 d treatment periods. All diets contained \u223c600 g forage/kg dry matter (DM; 5 kg DM of alfalfa hay and 7 kg DM of perennial ryegrass silage/day). The CON diet contained 303 g/kg DM of cracked wheat grain and 70 g/kg DM of solvent extracted canola meal and the CON diet was formulated to contain \u223c26 g total fat/kg DM. For the BG, HCC and HM diets, part of the cracked wheat and solvent extracted canola was substituted with the designated fat supplement so that the resulting diets contained 51, 52 and 65 g total fat/kg DM respectively. Fat supplementation did not influence DM intake and there were only small (P<0.05) positive effects on milk yield and negative effects on concentrations of milk fat and milk protein. The HM diet reduced (P<0.05) CH4 emissions when expressed either as g CH4/cow/d, g CH4/kg DM intake, or g CH4/L milk. The BG diet also (P<0.05) reduced CH4 emissions when expressed as g CH4/cow/d or g CH4/L milk, while the HCC diet decreased CH4 emissions in terms of g CH4/L milk. Combining data from the fat supplemented diets enabled comparison of CH4 emissions from the CON diet with CH4 emissions from the fat supplemented diets. Fat supplementation reduced (P<0.05) CH4 emissions: 500, 462 g CH4/cow/d; 25.0, 23.2 g CH4/kg DM intake and 23.3, 20.5 g CH4/L milk for the CON and fat supplemented groups respectively. Similarly, by combining data from all fat supplemented groups, regression analysis revealed that fat supplementation reduced CH4 emissions for at least 7 wk. Combining results of this investigation with data from the literature, we conclude that for each increase of 10 g/kg DM in dietary lipid concentration, enteric emissions are reduced by 0.79 g CH4/kg DM intake or \u223c3.5% thereby allowing estimation of the magnitude of enteric CH4 abatement based on dietary fat supplementation.

Previous in vitro studies have indicated a potential anti-methanogenic activity of garlic ( Allium sativum ), garlic oil (GO), and its main compound diallyl disulfide (DADS). In our study, effects of supplementation of a standard hay and concentrate diet with 5\u00a0g GO or 2\u00a0g DADS/kg dietary dry matter (DM) were tested in sheep in a duplicated 3\u00a0\u00d7\u00a03 Latin square design experiment with three 23\u00a0d periods. Respiratory measurements were on d 17 and 18. Dietary supplementation with GO or DADS had no influence on the amount of CH 4 produced (27\u00a0g/d). When rates of CH 4 production/kg OM digested were compared, DADS, but not GO, tended (P=0.09) to decrease CH 4 production compared to control. DM intake was not affected by GO or DADS, although concentrate intake was slightly decreased (P=0.10) with GO compared to control. DADS increased (P=0.02) digestibility of OM and aNDFom (P=0.03), as well as energy utilization (P=0.03) compared to control. Low palatability and lack of effect on either CH 4 mitigation or energy use efficiency indicate that a GO supplemented concentrate is of little relevance in practice. As DADS supplementation only tended to decrease CH 4 formation relative to OM digested, it too is limited use as a means of CH 4 mitigation. However, DADS supplementation improved digestibility and energy use efficiency.

It was reported that the reduction can be up to 30% compared with perennial ryegrass ( Lolium perenne ). To accurately evaluate the reduction, fresh chicory and perennial ryegrass in the vegetative state were fed to 24 wethers, 8 of which rumen-fistulated, at 1.3 and 2.2 times maintenance metabolisable energy requirements. Dry matter (DM) intake, whole tract apparent digestibility, rumen fermentation parameters and rumen liquid passage rate were measured in metabolism crates, and methane emissions determined using a calorimetric technique. Chemical analyses showed that chicory contained less DM, organic matter (OM), crude protein, neutral detergent fibre (aNDF), acid detergent fibre (ADF), cellulose and hemicellulose, but more hot water-soluble carbohydrate and pectin, than perennial ryegrass. Methane yield (g/kg DM intake) of wethers fed chicory did not differ from that of those fed perennial ryegrass. Yield was lower at the high versus the low feeding level of ryegrass. Apparent digestibility of DM and OM was higher, and aNDF, ADF, hemicellulose and cellulose was lower, in wethers fed chicory versus perennial ryegrass. In situ DM degradation rate of chicory was higher than that of perennial ryegrass. Rumen liquid passage rate was the same for wethers fed the two forages and higher at the high feeding level. The reduction in methane emissions by feeding vegetative chicory to wethers was limited, but increased feeding level reduces methane yields per unit of DM intake.", "keywords": ["2.

One set of traits, represented the polluting effect of dairy cows to the environment and the other represented cow production performance. To quantify the impact of dairy cows on the atmospheric environment, enteric methane per kg milk was estimated while non-milk nitrogen was estimated to quantify the potential pollution of dairy cows to ground water resources. The cow performance traits were energy corrected milk yield (ECM) and body energy content (EC). After correcting for systematic factors, highly significant differences were found between the production systems on their impact on the environment. Generally, an increase in production performance in terms of milk yield was associated with a decrease in enteric methane production per kg of milk. However, non-milk N per kg milk increased in the average genetic merit groups while non-milk N per ha increased in the more intensive production systems. This apparent trade-off highlights the importance of the need to incorporate the dynamics of emission burden and pollution potential of different dairy systems when characterising different dairy systems. Including the environmental cost of dairying in the general description of different dairy production systems will not only improve productivity but also not compromise the environment.", "keywords": ["2.

Thirty-two Huzhou lambs weaned at the age of 50\u00a0days, with an initial body weight of 14.2\u00a0\u00b1\u00a01.38\u00a0kg, were assigned to four dietary treatments in a 2\u00a0\u00d7\u00a02 factorial arrangement with TS (0 or 3\u00a0g/d) and SO (0 or 3% of DM). The diet without additives was considered as NTNS (no TS or SO). After a feeding trial for 60\u00a0days, four lambs from each treatment were moved to simple open-circuit respiratory chambers (two animals per chamber) to measure methane production for 3\u00a0days each measurement period. Animals were then slaughtered to obtain rumen samples for analysis of microbial ecology by real-time PCR. Populations of rumen methanogens, protozoa, fungi, Ruminococcus flavefaciens, and Fibrobacter succinogenes were expressed as a proportion of total rumen bacterial 16\u00a0S rDNA. Daily methane production was decreased (P\u00a0 \u00a00.05), but protozoa populations relative to total bacterial 16\u00a0S rDNA were decreased (P\u00a0<\u00a00.05) for lambs fed diets with TS, SO, and TS\u2013SO, with the lowest value in lambs fed the diet containing SO only. Population of methanogens was inhibited by SO (P\u00a0<\u00a00.05), but not by TS. Addition of SO and TS\u2013SO had an inhibitory effect on the population of fibrolytic microbes including R. flavefaciens and F. succinogenes.

Studies were conducted to evaluate the effects of feeding two concentrations of tannins from Mimosa spp. on rumen fermentation, methanogenesis and energy partitioning in goats. Adult male goats were used in three trials where three diets with increasing concentrations of tannins (control, low-tannin and high-tannin) were fed in a switch-over design. The control diet consisted of 0\uffc2\uffb765 timothy hay, 0\uffc2\uffb720 crushed maize and 0\uffc2\uffb715 soybean meal; low- and high-tannin diets contained 0\uffc2\uffb7975 and 0\uffc2\uffb7950 of the control diet, respectively, mixed with 0\uffc2\uffb7025 and 0\uffc2\uffb7050 of a commercial compound containing tannins with mean crude protein (CP) of 147 g/kg dry matter (DM) and gross energy (GE) 19 MJ/kg DM, respectively. Total contents (DM basis) of tannins (hydrolysable and condensed) in the control, low- and high-tannin diets were 0, 2\uffc2\uffb78 and 5\uffc2\uffb76 g/kg DM, respectively. The tannin source contained 37 and 76 g/kg DM of condensed and hydrolysable tannins, respectively (DM basis). The DM (664 g/d) and GE intakes (19\uffc2\uffb70 MJ/d) were similar among diet groups. Digestibilities of all dietary components in the high-tannin diet were lower (P\uffc2\uffa0<\uffc2\uffa00\uffc2\uffb705) than low-tannin and control diets. The faecal energy (MJ/d) output was lowest in the control diet (3\uffc2\uffb749) and increased (P\uffc2\uffa0<\uffc2\uffa00\uffc2\uffb705) in tannin-fed goats (3\uffc2\uffb780; 4\uffc2\uffb787) resulting in a corresponding decrease in digestible energy (DE). Methane emission, expressed both on absolute and per unit of feed intake basis, decreased (P\uffc2\uffa0<\uffc2\uffa00\uffc2\uffb705) with increasing concentration of tannins in the diet. For example, CH4 energy excretion was 0\uffc2\uffb798, 0\uffc2\uffb787 and 0\uffc2\uffb776 MJ/d for goats on control, low- and high-tannin diets, respectively, whereas their corresponding values for CH4 conversion ratio were 0\uffc2\uffb7079, 0\uffc2\uffb7069 and 0\uffc2\uffb7060 of GE intake. These results suggest that natural tannins, even at a low concentration (2\uffc2\uffb78 g/kg DM of the diet), reduce CH4 emissions, and tree leaves containing appreciable amounts of tannins may potentially be exploited as natural feed additives in ruminants.

Seventy-two Dutch Texel \uffc3\uff97 Greyface (Border Leicester \uffc3\uff97 Blackface) lambs, consisting of 36 males which were initially 36 (S.D. 4\uffc2\uffb79) kg liveweight and 36 females which were initially 34 (S.D. 2\uffc2\uffb75) kg liveweight were used. Ensiling significantly increased apparent digestibility of dry matter, energy and nitrogen (P<0\uffc2\uffb7001), but had no significant effect on methane energy loss as a proportion of gross energy intake, metabolizable energy intake (MEI), heat production, energy retained, efficiency of utilization of energy for growth (kg) or nitrogen retention. Supplementation of forage with concentrates resulted in a curvilinear decrease in heat production expressed as a proportion of MEI (P<0\uffc2\uffb705) and a linear increase in energy retention, expressed as an absolute value or as a proportion of MEI (P<0\uffc2\uffb705). Supplementation of forage tended to increase kg when calculated using Agricultural Research Council estimates of maintenance energy requirements, but had no significant effect when alternative estimates of maintenance were used. It is concluded that ensiling had no effect on efficiency of utilization of energy or nitrogen as measured by indirect calorimetry.
