Indigestible neutral detergent fibers (iNDF) accurately predict forage digestibility when measured in situ. The objective of this study was to determine the effects of rumen incubation times on the estimated concentrations of iNDF for four forages (alfalfa hay, corn silage, wheat straw and orchard grass), four concentrates (barley grain, soybean meal, beet pulp and wheat bran) and two ...

The purpose of this study was to determine the effect of rumen inoculum from heifers with fast vs. slow rate of in situ fiber digestion on the fermentation of complex versus easily digested fiber sources in the forms of untreated and Ammonia Fiber Expansion (AFEX) treated barley straw, respectively, using an artificial rumen simulation technique (Rusitec). In situ fiber digestion was measured i...

Cattle manure is frequently used as an inoculum for the start-up of agricultural biogas plants or as a co-substrate in the anaerobic digestion of lignocellulosic feedstock. Ruminal microbiota are considered to be effective plant fiber degraders, but the microbes contained in manure do not necessarily reflect the rumen microbiome. The aim of this study was to compare the microbial community comp...

Forages are the most important ingredient in a dairy cow’s ration. She is a ruminant and to be a healthy, productive cow she needs a healthy, productive rumen. High quality forages are the key to achieving a healthy rumen and a productive cow. However, because of the importance of forages in maintaining rumen health and cow performance, when deficiencies in the amount or quality of the forage i...

Label-MMAcid-Rev030410 BACKGROUND Ruminants are animals that have multiple stomachs to allow consumption and digestion of fibrous feedstuffs. Key to this digestive process is the bacterial breakdown of the fiber in the first stomach or rumen. The bacterial balance in the rumen can shift, allowing the ruminant to adapt to different diets. Ruminal bacteria convert fiber into lactate and volatile ...

the major aim of this study was to compare the morphology and activity of rumen protozoa of khuzestan water buffalo and holstein cow using in vitro digestibility and gas production parameters of steam treated sugarcane pith. rumen fluid obtained from two buffalo and cow steers fed the same diet, 30:70 concentrate: forage. to separate rumen protozoa, antibiotic solution and fungicides were added...

—Body mass – gut fill scaling relationships affect rate of digestion, foraging behavior, niche differentiation, and trophic interactions. On an intraspecific level, the scalar of this relationship has been reported to be both isoand allometric (,1.0). We hypothesized the scalar of rumen-reticulum fill depends on diet. When the diet has low concentrations of indigestible fiber the scalar should ...
