the nutritive values of non- processed and processed grape pomace with neurospora sitophila were evaluated. the chemical compositions and physical characteristics of samples were evaluated by laboratory analysis. an in vitro digestibility experiment was done to determine digestibility coefficients of dry matter, organic matter and also digestible organic matter in dry matter (domd) to estimate ...

the present study was conducted to investigate the possibility of using a modified in vitro gas production technique in place of the nylon bag method to estimate protein degradability of alfalfa hay in ruminants. in the in situ experiment dacron bags were filled with 3 g alfalfa hay. this was incubated in the rumen of three ruminally cannulated ghezel rams for the periods of 0, 2, 4, 8, 12, 16,...

The objective of this study was to estimate the protein degradability parameters of 6 common ruminant feedstuff using the nylon bags (in situ) and the innovative in vitro method-the DaisyII incubator. Significant differences were observed between the in situ and in vitro methods in estimation of the rapidly soluble (a) fraction (Pin vitro method were highly correlated with the estimated values ...

Current ruminant feeding systems depend on knowledge of the composition of feeds and the rate and extent of degradation of feed organic matter (OM) and crude protein (CP) in the rumen. The effect of storage and preparation of samples on in vitro gas production and fermentation characteristics of two common forage species, namely alfalfa and ryegrass werestudied. Samples were prepared as fresh (...

The in sacco protein and protein-free dry matter rumen degradability of three feeds, concentrate, alfalfa hay and maize silage, was determined simultaneously in three animal species: four Mediterranean buffalo (Bubalus bubalis) bulls, four Friesian bulls and four Delle Langhe rams, which received four diets differing in forage:concentrate ratio (1 5 87.5:12.5; 0.75 2 5 75.0:25.0; 3 5 62.5:37.5;...

the effect of inclusion of garlic essential oil (eo) at 33, 66 and 100 μg ml-1, raw garlic (gar) at 5, 10 and 15 mg ml-1 and monensin (mon) at 7.5 μg ml-1 of incubation medium on organic matter digestibility (omd) was studied with in vitro gas production, ankom daisyii and conventional in vitro (ivomd) methods. the material was incubated with sheep ruminal fluid and the experimental design was ...
