Significance Methane from enteric fermentation in the ruminant digestive system is a major contributor to anthropogenic greenhouse gas emissions United States and worldwide. also net loss of feed energy animal. This study was undertaken investigate effect methane inhibitor on lactating dairy cows. The experiment demonstrated that, under industry-relevant conditions, persistently decreased by 30% emissions, without negatively affecting animal productivity. spared partially used for tissue...
The objective of this study was to evaluate the effects dietary supplementation with live yeast (Saccharomyces cerevisiae), mannan-oligosaccharides and combination these additives on inflammatory response, ruminal parameters rumen morphology sheep fed a high grain-based diet.

Ruminant animals (domesticated or wild) emit methane (CH4) through enteric fermentation in their digestive tract and from decomposition of manure during storage. These processes are the major sources greenhouse gas (GHG) emissions animal production systems. Techniques for measuring CH4 vary direct measurements (respiration chambers, which highly accurate, but with limited applicability) to various indirect methods (sniffers, laser technology, practical, variable accuracy). The sulfur...
O objetivo neste trabalho foi avaliar o efeito da inclusão de fontes óleo na dieta cabras em lactação sobre a produção, composição e perfil dos ácidos graxos gordura do leite. Foram utilizadas quatro raça Saanen (54±1,02 kg PV) aos 80 dias lactação, canuladas no rúmen. Os tratamentos consistiram dietas suplementadas com diferentes (canola, arroz soja) uma controle. delineamento experimental utilizado quadrado latino 4 x os dados foram analisados utilizando-se procedimento MIXED SAS (2001)....
Four Angus steers (318 ± 16 kg) fitted with ruminal, duodenal, and ileal cannulas were used in a 4 × Latin square design to determine carbohydrate disappearance from the small intestine (SI). Steers fed fescue hay at 1.8% of BW abomasally infused starch hydrolysate (SH) 10, 20, or 40 g/h glucose (G) 30 g/h. Starch was raw cornstarch digested by heat-stable alpha-amylase. Experimental periods 10 d 6 adaptation, 3 digesta feces collection, 1 rest. Glucose (% infused) had greater (P < .001)...
Thirteen steers (378+/-23 kg) were used in a split-plot experimental design to evaluate the effect of small intestinal carbohydrate on sodium-glucose cotransport brush border membrane vesicles prepared from five equidistant sites along intestine. The consumed 7.2+/-0.4 kg/d ground fescue hay and soybean meal-based supplement infused ruminally or postruminally with partial alpha-amylase starch hydrolysate (914.5+/-8.3 g/d) for 7 d. On d 7, 1-m sections harvested frozen liquid N later...
We conducted three studies with steers to evaluate poultry by-product meal (PBM) as a supplemental N source for ruminants. An in situ study compared the solubility, degradation rate, and ruminal escape of PBM blood (BM), corn gluten (CGM), soybean (SBM) N. Additionally, an 84-d growth (n = 95, 228±5 kg BW) digestion trial (6 × 6 Latin square) were conducted. The basal diet consisted 49% silage, 36% cottonseed hulls, 15% supplement (DM basis).
