this research was conducted to determine the effect of gamma ray (gr) (100 and 150 kgy), sodium hydroxide (50 g/kg dm) and calcium oxide (160 g/kg dm) on gas production parameters and in vitro digestibility of soybean straw. all treatments, except for the gamma ray (100 and 150 kgy) did not have gas production up to 4 hours after incubation and there was a lag time. from 8 to 96 hours of incuba...

in this expriment, the effect of different levels of ziziphus zizyphus(zz) (0, 30 or 60 mg) on fermentation parameters, total protozoa population  and three sub family of protozoa  entodiniinae, ophryscolecinae, diplodiniinae and family of isotrichdaeandmethane gas production was assessed using in vitro method and a completely randomized design. the rate of gas production for the insoluble frac...

The current study evaluated the effects of electron beam (EB; 10, 20, 30 and 40 kGy), urea and NaOH treatments on chemical composition, phenolic compounds, in vitro gas production and in situ ruminal degradability of pistachio by-product (PB). The EB decreased (p < 0.01) neutral detergent fiber (NDF), acid detergent fiber (ADF) and acid detergent lignin (ADL) contents...

theaim of the current study was to assess effects of different levels of origanum vulgare (0, 250, 500, 750 and 1000 mg/l) on kinetics of gas production, some ruminal digestion and fermentation parameters, methane production and also to determine its potential in controlling rumen acidosis using in vitro method in four separate phases. in the first phase, the asymptote of gas production (a) and...

the current study evaluated the effects of electron beam (eb; 10, 20, 30 and 40 kgy), urea and naoh treatments on chemical composition, phenolic compounds, in vitro gas production and in situ ruminal degradability of pistachio by-product (pb). the eb decreased (p < 0.01) neutral detergent fiber (ndf), acid detergent fiber (adf) and acid detergent lignin (adl) contents of pb. treating pb by naoh...

the aim of this study was investigating the effect of gamma irradiation and naoh treatment of some agricultural by products (tomato pulp, orange pulp, pistachio hull and wheat straw) on fermentation parameters and gas production test. treatments of gamma irradiation (50, 100 and 200 kgy) and %5 naoh was done on each source of by products. the results showed that gamma irradiation at the dose of...

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 aim of this study was to evaluate the effects of adding sulfuric acid to sugarcane topssilage on rumen bacteria and whole rumen microorganisms (WRM) and compare the digestibility of sugarcane tops treated with different amount of urea, molasses and sulfuric acid between Holstein cow and Khouzestan buffalo. Regardless of the type of the treatment, potential of gas production (B) by cow WRM (...

introduction since the legislation of european :union: has prohibited the use of growth-promoting antibiotics such as: monensin, there is an interest in alternatives to manipulate the rumen fermentation. the use of growth-promoting antibiotics in animal feeds is banned in europe due to having potential risks such as the spread of antibiotic resistance genes or the contamination of milk or meat ...
