The chemical composition, degradability coefficients (in situ) and ruminal-intestinal disappearance(mobile bag procedure) of dry matter (DM) and crude protein (CP) were evaluated for olive cake (OC)silages treated (DM basis) with additives as follows: (1) untreated OC, (2) OC + 0.5% urea, (3) OC + 0.4%formic acid, (4) OC + 8% molasses, (5) OC + 0.5% urea + 8% molasses, (6) OC + 0.5% urea + 0.4%...

An extensive in vitro study was conducted to delineate the influence of levels and source of sulfur besides rumen fungi habitat on the degradation of pearl millet stover dry matter and fibrous constituents. The results revealed that degradability of dry matter, organic matter, acid detergent fibre, neutral detergent fibre and cellulose from pearl millet stover was maximized (P<0.05), irrespecti...

this study was conducted to evaluate the effect of electron beam irradiation at doses of 250 and 500 kgy on the chemical composition and ruminal dry matter (dm) and neutral detergent fiber (ndf) degradability of wheat straw. nylon bags of untreated or irradiated wheat straw were suspended in the rumen of three rams for up to 72 h, and resulting data were fitted to non-linear degradation model t...

This trial describes the effect of intraruminal infusion of sodium selenite on the in-sacco rumen degradability of a legume, Centrosema pubescens and a grass, Pennisetum purpereum in West African dwarf (WAD) sheep. A total of sixteen WAD sheep of an average body weight, 16.19 ± 2.63 kg were used for this study. A 4 x 4 Latin square design of four sheep and four sodium selenite treatments (doses...

In vitro methods have been standardized and tested to correctly simulate the rumen environment fermentation process. A few studies verified that feed degradability achieved as a result of stirring samples is higher when are incubated under continuous than they only stirred twice daily. The objective this study has verify effect speed on during incubation. For purpose, apparent true dry matter (...

A study was conducted to evaluate the effects of chitosan on in situ nutrient degradability and ruminal fermentation of beef steers consuming bermudagrass hay. Eight ruminally-cannulated steers were provided Tifton-85 bermudagrass hay ad libitum while housed in the University of Florida Feed Efficiency Facility at the North Florida Research and Education Center (NFREC) in Marianna for two 21-d ...

The objective of the study was to quantify annual and seasonal differences in the chemical composition, in vitro gas production, in situ degradability and ruminal fermentation of grazing steers' diets. Diet samples were collected with four esophageal cannulated steers (350±3 kg BW); and four ruminally cannulated heifers (342±1.5 kg BW) were used to study the dry matter degradation and fermentat...
