Journal of Dairy Science, 1972 Abstract The effect of altering ruminal pH on volatile fatty acid production in vitro or volatile acid concentration in vivo was investigated. In Experiment 1 three lactating Holstein cows fitted with ruminal cannulae were fed a high-concentrate, restricted roughage ration.

Animal Research and One Health, EarlyView.This study aimed to investigate the effects of cellulase and Lactobacillus plantarum on the silage quality, in situ digestibility, and microbial communities of apple pomace silage. The combined supplementation of cellulase and Lactobacillus plantarum in apple pomace silage improved fermentation quality and enhanced rumen utilization efficiency.

Live yeast as a possible modulator of polyunsaturated fatty acid biohydrogenation in the rumen [PDF]
, 2010 In dairy cows, several studies focused on the effects of sodium bicarbonate and fibre on ruminal linoleic acid (c9c12-C18:2) biohydrogenation (BH) whereas literature is scarce about the effect of live yeast, used as a feed additive. The objective of this

Variation in Weed Seed Fate Fed to Different Holstein Cattle Groups. [PDF]
, 2016 Weed seeds may maintain their viability when passing through the digestive tract of cattle and can be therefore dispersed by animal movement or the application of manure. Whether different cattle types of the same species can cause differential weed seed

JSFA reports, EarlyView.Abstract Background Livestock, especially ruminants, are a major source of global methane emissions, primarily produced by methanogenic archaea during enteric fermentation. We performed a systematic review and meta‐analysis to account for factors that could influence the relationship between ruminal methanogenic populations and methane emissions, such ...

Invited review: Ruminal acidosis and its definition—A critical review
Journal of Dairy Science: Ruminal acidosis occurs as a continuum of disorders, stemming from ruminal dysbiosis and disorders of metabolism, of varying severity. The condition has a marked temporal dynamic expression, resulting in cases expressing quite different rumen ...

El pH afecta la digestió en els remugants [PDF]
, 2007 El pH del medi ruminal no és constant, sinó que fluctua durant el dia en funció del tipus de dieta, la freqüència d'administració, el nivell d'ingestió, etc. Aquestes fluctuacions poden afectar la flora microbiana del rumen i a la fermentació. El Grup de

Quantitative analysis of ruminal methanogenic microbial populations in beef cattle divergent in phenotypic residual feed intake (RFI) offered contrasting diets [PDF]
, 2014 peer-reviewedBackground Methane (CH4) emissions in cattle are an undesirable end product of rumen methanogenic fermentative activity as they are associated not only with negative environmental impacts but also with reduced host feed ...

The Efficacy of Food‐Grade Substances to Protect Dietary Glutamine From Ruminal Degradation
Journal of Animal Physiology and Animal Nutrition, EarlyView.ABSTRACT This study was conducted to investigate the use of four, low cost, food‐grade substances to protect glutamine from microbial degradation in vitro, and subsequently validate their efficacy in vivo. Two in vitro trials were conducted using 250 mL bottles replicated in triplicate to test beeswax‐, paraffin wax‐, zein‐, and rice bran wax ...
