Enhanced Degradation of 3-Nitropropanol by Ruminal Microorganisms

Journal of Animal Science, 1986
Ruminal fluid was obtained over a 4-yr period from cattle on various diets and supplements to determine the effects of different inocula on the microbial degradation of 3-nitropropanol (NPOH), a toxic metabolite in certain Astragalus spp. (Leguminosae). Nitrite (NO2-) metabolism was also studied in vitro because rapid NO2- reduction is required for the

Preservation of ruminal microorganisms for in vitro determination of ruminal protein degradation.

Journal of Animal Science, 1996
Ruminal microorganisms, preserved either lyophilized or frozen, were compared with freshly strained ruminal fluid for proteolytic activity and as inoculum source for determination of ruminal protein degradation rates by the inhibitor in vitro method. Dialysis and glycerol addition had no effect on the proteolytic activity of preserved microorganisms ...

Cellulose Degradation by Ruminal Microorganisms

Critical Reviews in Biotechnology, 1992
The rumen is a highly developed digestive organ in which feed material, particularly plant fiber, is efficiently digested by a complex microbial fermentation.

Ruminal Degradation and Outflow of Amino Acids in Cows

Journal of Veterinary Medicine Series A, 1989
SummaryTwo rumen‐ and duodenum‐cannulated cows were used to study the disappearance rate, degradation in, and outflow from the rumen of four amino acids administered individually into the rumen at the following dose levels (mmol): lysine 273–547‐820, tyrosine 276–496‐828, isoleucine 381–762‐1143, methionine 335.

Measuring resistance to ruminal degradation and bioavailability of ruminally protected methionine

Animal Feed Science and Technology, 2000
The objectives of this study were to evaluate ruminal degradation and intestinal digestion of two ruminally protected methionine (RPM) products and to assess the potential use of changes in plasma methionine concentrations as an indication of methionine availability to the animal.

Post-ruminal phytate degradation in sheep

Animal Feed Science and Technology, 2002
Abstract This experiment was conducted to study phytate (inositol hexaphosphate) degradation in the post-ruminal digestive tract of sheep. Three sheep were fed a diet containing 20% rapeseed meal at intervals of 2 h for 5 days and then digesta were collected from the abomasum, small intestine, upper large intestine and lower large intestine.

Differential ruminal degradation of alfalfa proteins

Canadian Journal of Plant Science, 2009
Alfalfa (Medicago sativa L.) has high crude protein that is rapidly and extensively degraded in the rumen. Our objective was to develop a protocol where individual proteins could be characterized for their ruminal degradation. Proteins from individual genotypes of three alfalfa cultivars were characterized using fluorescence 2D difference gel ...

In sacco evaluation of ruminal degradability of waste vinegar residue as a feedstuff for ruminants

Animal Production Science, 2013
Waste vinegar residue (WVR) is a by-product of vinegar processing by solid-state fermentation. In this study, two experiments were conducted to determine chemical composition and ruminal degradability of WVR and whether WVR can be used as a feedstuff for ruminants.

Degradability of Legumes Proteins in Ruminant Nutrition

Journal of Ethology & Animal Science, 2019
Legumes are the main source of protein and the main constituents of ruminant meals. This place is occupied by the ability of biological nitrogen fixation and because of their high nutritional value. They significantly reduce production costs – less application of nitrogen mineral fertilizers and a lower proportion of concentrated nutrients in ruminants
