Journal ArticleDOI
Proteolytic activity in ruminal fluid from cattle fed two levels of barley grain: a comparison of three methods of determination
TL;DR: Proteolytic activity in ruminal fluid from cattle fed two levels of barley grain: a comparison of three methods of determination.
Journal ArticleDOI
Impact of adding Saccharomyces strains on fermentation, aerobic stability, nutritive value, and select lactobacilli populations in corn silage.
Lysiane Dunière,L. Jin,Brenda K. Smiley,M. Qi,Rutherford William M,Yanan Wang,Tim A. McAllister +6 more
TL;DR: The ability of silage to be used as a means of delivering Saccharomyces strains to ruminants was assessed and it was demonstrated that the density of these yeast strains would increase between the time that silage was removed from storage and the time it was fed.
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
Runoff Losses of Excreted Chlortetracycline, Sulfamethazine, and Tylosin from Surface-Applied and Soil-Incorporated Beef Cattle Feedlot Manure
Inoka Amarakoon,Francis Zvomuya,Allan J. Cessna,Dani Degenhardt,Francis J. Larney,Tim A. McAllister +5 more
TL;DR: Although the results confirm that cattle-excreted veterinary antimicrobials can be removed via surface runoff after field application, the magnitudes of chlortetracycline and sulfamethazine losses were reduced by soil incorporation of manure immediately after application.
Journal ArticleDOI
Susceptibility to tulathromycin in Mannheimia haemolytica isolated from feedlot cattle over a 3-year period
TL;DR: It was shown that tulathromycin resistance in M. haemolytica from a general population of feedlot cattle in western Canada was low and did not change over a 3-year period after tulathroromycin was approved for use in cattle.
