Methane production and diurnal variation measured in dairy cows and predicted from fermentation pattern and nutrient or carbon flow

Animal, 2015
Many feeding trials have been conducted to quantify enteric methane (CH4) production in ruminants. Although a relationship between diet composition, rumen fermentation and CH4 production is generally accepted, the efforts to quantify this relationship ...

Hempseed cake as a protein feed for ruminants [PDF]

, 2010
Increasing the use of locally produced protein feeds in ruminant production systems in northern Europe would be a valuable development. Hemp (Cannabis sativa L.) can be cultivated at high latitudes and cold-pressing the seeds to extract the oil produces ...

Starch plus sunflower oil addition to the diet of dry dairy cows results in a trans-11 to trans-10 shift of biohydrogenation [PDF]

, 2013
Trans fatty acids (FA), exhibit different biological properties. Among them, cis-9,trans-11 conjugated linoleic acid has some interesting putative health properties, whereas trans-10,cis-12 conjugated linoleic acid has negative effects on cow milk fat ...

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 ...

Influence of Inoculum Content on Performance of Anaerobic Reactors for Treating Cattle Manure using Rumen Fluid Inoculum [PDF]

, 2009
Biogas productions of cattle manure using rumen fluid inoculums were determined using batch anaerobic digesters at mesophilic temperatures (room and 38.5 oC). The aim of this paper was to analyze the influence of rumen fluid contents on biogas yield from

Feeding Laboratory Mice: Comparing a Standard Versus a Purified Diet – Marked Effects on Digestive Physiology

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Diet composition and processing have a major impact on its utilisation by the animal, as is known from farm and pet animal species. This includes effects on energy and nutrient digestibility, the intermediary metabolism, and the intestinal microbiome, with all the resulting impacts. For laboratory animals, data is scarce on influencing factors

Impact of zearalenone on quorum sensing signaling molecules and its association with the suppression of ruminal microbial fermentation in a RUSITEC system

Journal of Animal Science and Biotechnology
Background Zearalenone (ZEN), a common mycotoxin in ruminant diets, could disturb the rumen ecosystem and impair rumen fermentation. Noticeably, ZEN has been shown to reduce the relative abundances of specific bacterial taxa that potentially possess ...

Isolation of Cellulose Degrading Bacteria from Rumen and Evaluation of Cellulase Production by the Isolate Using Lignocellulosic Substrate

Ethiopian Journal of Science and Sustainable Development, 2020
The utilization of cheaper substrates reduces cost of cellulase production and there is the need for cellulolytic microbes capable of degrading lignocellulosic materials.
