High-Gossypol Whole Cottonseed Exhibited Mediocre Rumen Degradability and Less Microbial Fermentation Efficiency than Cottonseed Hull and Cottonseed Meal with an In Vitro Gas Production Technique

Fermentation, 2022
To explore whether or not the gossypol varied in cottonseed by-products affect rumen degradability and fermentation efficiency, an in vitro cumulative gas production experiment was applied with mixed rumen microorganism to compare rumen fermentation ...

Cellulosic waste degradation by rumen-enhanced anaerobic digestion

Water Science and Technology, 2003
Anaerobic digestion of lignocellulosic material is carried out effectively in many natural microbial ecosystems including the rumen. A rumen-enhanced anaerobic sequencing batch reactor was used to investigate cellulose degradation to give analysis of overall process stoichiometry and rates of hydrolysis. The reactor achieved VFA production rates of 207-

Effect of Lupinus albus as protein supplement on yield, constituents, clotting properties and fatty acid composition in ewes' milk [PDF]

, 2006
The effect of feeding lupin seeds (Lupinus albus L.) as an alternative protein source in ewe diets was investigated. Two groups of 18 Sarda ewes were fed two different isonitrogenous diets: with lupin (L) seed, given after 12 h soaking, or soybean meal ...

Rumen degradability of some feed legume seeds [PDF]

Animal Research, 2003
Dégradabilité ruminale de certaines graines de légumineuses. Ce travail avait pour but d'étudier la dégradabilité théorique (DT) dans le rumen des matières azotées totales (MAT) de différentes graines de légumineuses en essayant de les mettre en relation avec leurs caractéristiques chimiques ou physiques.

Interaction effects of degradable nitrogen sources and straw treatment on rumen parameters and microbial protein synthesis in sheep

Indian Journal of Animal Sciences, 2014
In this study, the effects of 2 rumen degradable nitrogen, N, source (urea vs. casein) were investigated on rumen degradability, ammonia concentration, dilution rate, microbial protein synthesis (MPS) and MPS efficiency (EMPS) in sheep fed diet based on

Enzymatic Degradation of Hydroxamate in Rumen Microbes

Journal of Dairy Science, 1983
Abstract The enzyme responsible for degradation of acetohydroxamic acid was intracellular. Bacterial and not the protozoal fraction contributed the enzyme activity in the rumen. The enzyme was cell bound and required cofactors in the soluble portion of the cell for activity. Optimum pH and temperature were 7.0 and 39°C. The enzyme was heat stable.
