the objective of this study was to evaluate the effects of supplementation of different level protein diets with rumen protected methionine and lysine on performance and ruminal parameters in holstein dairy cows when in their early lactation. twenty one dairy cows in their early lactations were assigned to three treatments in a randomized block design experiment of a 35-d duration period. diets...

different levels of grape pomace extract (ge) were evaluated for their effect on in vitro gas production and as well on some such ruminal fermentation parameters as apparent degraded substrate, volatile fatty acids (vfa), and microbial protein production, in sheep, as ruminal inoculum donor. as for extraction, dried grape pomace and distilled water were mixed in an equal weight ratio. ge was ad...

Rice straw (Rs) was treated by a sodium chlorite/acetic acid mixture (Sct), ammoniation (At) and alkaline hydrogen peroxide (Athp) methods. The objective was to compare their degradation and fermentation products in the presence or suppression of anaerobic fungi. Significant differences (P < 0.01) in degradation of straws were observed during all periods of incubation with Sct having the highes...

The effects of increasing concentrations of oregano (Origanum vulgare L.) and rosemary (Rosmarinus officinalis L.) essentials oil (EO) on ruminal gas emissions were tested in vitro using 50 mL serum bottles. Each bottle contained a 200 mg substrate (alfalfa hay and corn meal 1:1) and a 20 mL solution composed of a buffered medium and rumen fluid (1:2). The percentage of ruminal fermentation pro...

This study was carried out to determine the effects of supplementing different levels (0, 0.5 and 1% of buffered rumen fluid) of methanolic extract of pomegranate peel, on rumen fermentation kinetics of four oil seed meals (soybean meal, cotton seed meal, rapeseed meal and sunflower seed meal), using in vitro gas production technique. The samples were incubated in syringes containing rumen liqu...

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 ...

abstract             this study was conducted to investigate the effects of different levels of yeast and molasses on chemical composition and nutritional value of artiplex lentiformis silage. the levels of yeast include: zero (control), 2.5 and 5 g/kg dry matter and levels of molasses include: zero (control), 10 and 15 percent that were added to atriplex and then ensiled. the experiment arrang...

The aim of this study was to determine the chemical composition of stem and compost of the button mushroom to estimate metabolizable energy (ME) and net energy of lactation (NEl) using gas production method and to determine the amount of dry matter disappearance (DMD) using in vitro technique. This study was conducted in a completely randomized design with three treatments o...
