Journal ArticleDOI
Comparison of two live Bacillus species as feed additives for improving in vitro fermentation of cereal straws.
Zuo Wang,Zhixiong He,Zhixiong He,Karen A. Beauchemin,Shaoxun Tang,Chuanshe Zhou,Xuefeng Han,Min Wang,Jinhe Kang,Nicholas E. Odongo,Zhiliang Tan +10 more
TL;DR: Results obtained in this research suggest that B. licheniformis would be preferred as a live Bacillus additive in comparison with B. subtilis, and its optimal dose should be 0.25 × 10(7) cfu/500 mg substrates.
Journal ArticleDOI
Ruminal and intestinal amino acid digestion of distiller's grain vary with grain source and milling process
TL;DR: In this article, a study was conducted to evaluate the in situ ruminal degradability of crude protein (CP), amino acid (AA) profiles of RUP, and in vitro intestinal digestibility of AA for dried distillers grains with solubles (DDGS) as affected by grain source (corn vs. wheat) and milling process (conventional vs. fractional).
Journal ArticleDOI
Comparative analysis of gene expression profiles in ruminal tissue from Holstein dairy cows fed high or low concentrate diets
TL;DR: Microarray analysis revealed that a cAMP-dependent protein kinase A catalytic subunit beta (PRKACB), may be associated with ruminal tissue maintenance, and contributed to understanding of the regulatory mechanisms at the mRNA level for Holstein cows fed at different concentrate ratio diets.
Journal ArticleDOI
Substitution of wheat dried distillers grains with solubles for barley silage and barley grain in a finishing diet increases polyunsaturated fatty acids including linoleic and alpha-linolenic acids in beef
M. L. He,M. L. He,W.Z. Yang,Michael E. R. Dugan,Karen A. Beauchemin,John J McKinnon,Tim A. McAllister +6 more
TL;DR: In this paper, the effects of wheat dried distillers grain with solubles (WDDGS) on fatty acid profiles of steers were investigated when it was substituted for barley silage in a barley grain finishing diet.
Journal ArticleDOI
Universally applicable methane prediction equations for beef cattle fed high- or low-forage diets
TL;DR: In this paper, empirical equations specific for high and low-forage diets were developed to improve the prediction of enteric methane production (eCH4) from beef cattle, and a database built from the database was used.
