Journal ArticleDOI
Understanding variability and repeatability of enteric methane production in feedlot cattle
TL;DR: In this paper , the authors investigate the variation in CH4 production among and within growing beef cattle, identify low CH4 emitters, and examine relationships between CH4 emissions and intake, feeding behavior, growth, and rumen fermentation.
Journal ArticleDOI
Effect of Metabolizable Protein Supply on Milk Performance, Ruminal Fermentation, Apparent Total-Tract Digestibility, Energy and Nitrogen Utilization, and Enteric Methane Production of Ayrshire and Holstein Cows
Chaouki Benchaar,F. Hassanat,Karen A. Beauchemin,D.R. Ouellet,Hélène Lapierre,Cristiano Côrtes +5 more
TL;DR: In this article , the effect of increasing metabolizable protein supply (85, 100, and 115% of requirement) on milk production, energy and nitrogen (N) utilization, and enteric methane (CH4) emissions of Ayrshire and Holstein cows was investigated.
Journal Article
Fiber degradability, chemical composition and conservation characteristics of alfalfa haylage ensiled with exogenous fibrolytic enzymes and a ferulic acid esterase-producing inoculant
TL;DR: Lynch et al. as discussed by the authors investigated the effects of two fibrolytic enzyme products, applied at baling alone or in combination with a ferulic acid esterase-producing bacterial additive, on the ensilage dynamics, chemical composition and digestibility of alfalfa haylage.
Journal ArticleDOI
Effect of Physically Effective Neutral Detergent Fiber and Undigested Neutral Detergent Fiber on Eating Behavior, Ruminal Fermentation and Motility, Barrier Function, Blood Metabolites, and Total Tract Digestibility in Finishing Cattle.
Murillo C Pereira,Karen A. Beauchemin,Tim A. McAllister,Wenzhu Yang,K. M. Wood,Gregory B Penner +5 more
TL;DR: In this paper , the effects of physically effective neutral detergent fiber (peNDF) and undigested Neutral Detergent Fiber (UDF) on eating behavior, ruminal fermentation and motility, barrier function, blood metabolites, and total tract nutrient digestibility for finishing cattle were evaluated.
Journal ArticleDOI
PSV-B-20 Effect of Physically Effective Neutral Detergent Fiber, and Undigested Neutral Detergent Fiber on Eating Behavior, Ruminal pH, Ruminal Motility, and Total Tract Permeability for Finishing Cattle
Murillo C Pereira,Aniele B Franceschi,K. M. Wood,Wen Z. Yang,Karen A. Beauchemin,Tim A. McAllister,Gregory B Penner +6 more
TL;DR: In this article , the effects of physically effective neutral detergent fiber (peNDF), and undigested Neutral Detergent Fiber (uNDF) on dry matter intake (DMI), eating behavior, ruminal fermentation, and total tract permeability for finishing cattle were evaluated.
