Estimation of stoichiometric parameters for rumen fermentation of roughage and concentrate diets.
A biochemical model coupled with an iterative nonlinear least-squares program was used to estimate stoichiometric parameters for fermentat ion of soluble carbohydrate, starch, hemicellulose, cellulose and protein in the rumen. Fermentat ion parameters were deduced for two sets of l i terature data, on (1) a roughage group of 60 diets fed to 137 animals and (2) a concentrate group of 48 diets fe...
متن کاملNet utilization of roughage and concentrate diets by sheep.
1. Two diets, an all-roughage diet and a high-concentrate diet, were fed at two levels, a low level of estimated 1-5 times maintenance energy requirement and a higher level of estimated two times maintenance energy requirement, to South African Mutton Merino castrated male sheep, aged 13 months and in fairly lean condition at the start of the 93 d experimental period. 2. Body composition and en...
متن کاملThe effect of change from low-roughage to high-roughage diets on rumen fermentation, blood composition and milk fat secretion in the cow.
I. Changing cows from a diet with low hay and high flaked maize content, which depressed milk fat secretion, to a high-roughage diet resulted in increased milk fat secretion and in changes in the pattern of rumen fermentation and in the composition of the blood plasma. 2. During the 1st week following the change in diet the proportions of propionic and valeric acids in the rumen decreased and t...

متن کاملRumen bacterial communities can be acclimated faster to high concentrate diets than currently implemented feedlot programs
AIMS Recent studies have demonstrated RAMP, a complete starter feed, to have beneficial effects for animal performance. However, how RAMP may elicit such responses is unknown. To understand if RAMP adaptation results in changes in the rumen bacterial community that can potentially affect animal performance, we investigated the dynamics of rumen bacterial community composition in corn-adapted an...
