this study was carried out to the determination of nutritive value of canola meal using naylon bag and cumulative gas production techniques in gizel sheep. tow fistulated gizel sheep with average bw 45±2 kg used in a complete randomized design. the cumulative gas production was measured at 2, 4, 6, 8, 12, 16, 24, 36 and 48 h and ruminal dm and cp disappearance were measured up to 96 h. coeffici...

the present study was carried out to determine the nutritive value of white varieties of grape pomace (gp) and raisin vitis leaves (rvl), using nylon bags and gas production techniques. tow fistulated whether with average body weight of 45±2 kg were used. the amount of gas produced was measured at 2, 4, 6, 8, 12, 16, 24, 36, 48 and 72 h times and degradation was measured using nylon bags up to ...

This study was carried out to determine the chemical composition and estimation of nutritive value of apple pomace (AP) by-product using in vitro gas production technique. Fermentation of AP samples were carried out with rumen fluid obtained from three mature canulated steers. The samples were collected from SanSan Shahd factory in Urmia, Iran. The amount of gas production for AP at 2, 4, 6, 8,...

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...

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...

The possibility of using water insoluble fraction from biomass pyrolysis oil as additive in synthesis of Wood-Plastic novolac has been proved by using Differential Scanning Calorimetry (DSC) and Fourier Transformed Infra Red (FT-IR) spectroscopy. Synthesis of novolac with different concentrations (10, 20 and 30 wt %) of water insoluble fraction were performed. It was found that mechanical p...

Fifty-four roughages of known voluntary dry-matter intakes (DMI; range 7.8-35.2 g/kg live weight per d) were examined in vitro in a gas production test. Samples (200 mg) of roughage and roughage neutral-detergent fibre (NDF) respectively were incubated in a mixed suspension of rumen contents for 96 h and the gas volumes recorded after 4, 6, 8, 12, 24, 30, 36, 48, 54, 60 and 96 h. The kinetics o...

The current ruminant feeding models require parameterization of the digestion kinetics of carbohydrate fractions in feed ingredients to estimate the supply of nutrients from a ration. Using an automated gas production technique, statistically welldefined digestion rate of carbohydrate, including soluble carbohydrate, can be estimated in a relatively easy way. In this study, the gas production d...

nutritive value of ephedra (ephedra intermedia) was evaluated through determination of chemical compositions, in situ degradability and in vitro gas production techniques using three permanently fistulated adult baluchi sheep. the samples were harvested during the late spring from rangeland in north of khorasan razavi province. the rate of gas production and degradability characteristics of dry...
