Journal ArticleDOI
In situ and in vitro evaluations of a slow release form of nitrate for ruminants: Nitrate release rate, rumen nitrate metabolism and the production of methane, hydrogen, and nitrous oxide
TL;DR: In situ and in vitro experiments were conducted to determine nitrate (NO3−) release rate from encapsulated NO3− (EN) in the rumen and to examine metabolism of EN− in conjunction with methane (CH4), hydrogen (H2), and nitrous oxide (N2O) production.
Journal ArticleDOI
Use of sodium bicarbonate, offered free choice or blended into the ration, to reduce the risk of ruminal acidosis in cattle
TL;DR: In this article, a study was conducted to determine whether feeding sodium bicarbonate (SB) reduces the risk of subacute ruminal acidosis in cattle fed high concentrate feedlot finishing diets.
Journal ArticleDOI
Evaluation of Different Yeast Species for Improving In vitro Fermentation of Cereal Straws
Zuo Wang,Zhixiong He,Karen A. Beauchemin,Shaoxun Tang,Chuanshe Zhou,Xuefeng Han,Min Wang,Jinhe Kang,Nicholas E. Odongo,Zhiliang Tan +9 more
TL;DR: The current results indicate that C. tropicalis is more preferred as yeast culture supplements, and its optimal dose should be 0.25×107 cfu/500 mg substrates in vitro.
Journal ArticleDOI
Lignin impact on fiber degradation. IV. Enzymatic saccharification and in vitro digestibility of alfalfa and grasses following selective solvent delignification
TL;DR: In this paper, the response of alfalfa and various grasses to selective solvent delignification (SSD), as well as the nutritive value of the residual biomass (co-product), was determined.
Managing Rumen Fermentation in Barley- Based Diets: Balance Between High Production and Acidosis
TL;DR: Owens et al. as mentioned in this paper showed that lactic acid concentrations in the rumen exceeding 40 mM are indicative of severe acidosis, although acidosis can occur without build-up of Lactic acid.
