Journal ArticleDOI
Co-composting of Beef Cattle Feedlot Manure with Construction and Demolition Waste.
Xiying Hao,Brett Hill,Pam Caffyn,Greg R. Travis,Andrew F. Olson,Francis J. Larney,Tim A. McAllister,Trevor W. Alexander +7 more
TL;DR: Final composts had similar total C, total N, C/N ratios, and water-extractable K, Mg, and NO content across all treatments, however, adding C&D waste increased δC, δN, water-Extractable SO, and Ca contents and decreased pH, total P (TP), water- Extractable C, N, and P and most volatile fatty acids (VFA).
Journal ArticleDOI
Use of naturally sourced feed additives (lactobacillus fermentation products and enzymes) in growing and finishing steers: Effects on performance, carcass characteristics and blood metabolites
TL;DR: This article evaluated the use of naturally sourced feed additives that consisted of lactobacillus fermentation products (LFPs), plant based enzymes and prebiotics as alternatives to antibiotics in the diets of growing and finishing beef steers.
Journal ArticleDOI
Effect of diastatic power and processing index on the feed value of barley grain for finishing feedlot cattle.
TL;DR: Assessment of the nutritional value of barley grain differing in diastatic power and processing index suggests that although low-DP barley increased liver abscesses, differences in DP did not alter digestion or growth performance but low- DP barley did improve dressing percentage.
Journal ArticleDOI
Defining risk for low reticuloruminal pH during the diet transition period in a commercial feedlot in western Canada.
B. I. Wiese,Steve Hendrick,J. G. Campbell,John J McKinnon,Karen A. Beauchemin,Tim A. McAllister,G. B. Penner +6 more
TL;DR: The data suggest that the risk for low reticuloruminal pH increases with increasing proportion of concentrate in the diet, and the results suggest that susceptibility to low retiuloruminals pH may differ between steers and heifers.
Journal ArticleDOI
Evaluation of the Feed Value for Ruminants of Blends of Corn and Wheat Distillers Dried Grains
Daalkhaijav Damiran,Arjan Jonker,Xuewei Zhang,Xuewei Zhang,M. Yari,John J McKinnon,Tim A. McAllister,Saman Abeysekara,Peiqiang Yu +8 more
TL;DR: The inclusion of the biofuel coproduct up to 25-50% in rations improved potential nitrogen and energy synchronization for microbial growth and improved truly absorbable protein supply to the small intestine, without altering energy value.
