An in vitro gas production technique was used to evaluate the effects of different adsorbents on the gas production parameters of lead-exposed diet. Ruminal fluid, obtained from fistulated sheep (3-4 years of age and 40±5 kg BW), and experimental diets samples, 200 ± 0.2 mg DM, were incubated in 100 mL glass bottles. To each bottle, one of the following treatments was applied: 1) control (no Pb...

This study was conducted to determine in vitro crude protein degradation (IVDP) parameters and effective crude protein degradability (EPD) of various feeds using the modified in vitro gas production (GP) technique. Feed samples were alfalfa hay, soybean meal, soybean, rapeseed meal, sunflower meal and fish meal. Rumen fluid was collected before the morning feeding from four rumen fistulated lam...

Five steam-flaked sorghum grain (SFSG) samples with bulk densities of 476, 412, 347, 309 and 283 g/liter made by adjusting tension between mill rollers and three reconstituted sorghum grain (RSG) samples with reconstitution times of 10, 20 and 30 d and a control sample were analyzed for gas production kinetics (rumen liquor fermentation) and enzymatic glucose release (amyloglucosidase). Protein...

Introduction Different barley varieties have been shown to affect in vitro dry-matter digestibility (IVDMD), ruminal starch digestion and animal performance (Boss and Bowman, 1996). Some of these differences may be due to differences in site and extent of nutrient digestion among barley varieties. Little information is available on digestive characteristics of different barley varieties and sev...

An in vitro gas production technique was used to investigate the associative effects of untreated or biologically-treated linen straw with berseem hay (H). The linen straw (LS) was biologically treated with white rot fungi (TLS). Ground samples (200 mg DM) of H, LS, TLS and the mixtures (50% w/w) of H + LS and H + TLS were incubated in 100 ml glass syringes with buffered rumen fluid. Cumulative...

Several studies have demonstrated that methane production from hydrate-bearing porous media by means of depressurization-induced dissociation can be a promising technique. In this study, a 2D axisymmetric model for simulating the gas production from hydrates by depressurization is developed to investigate the gas production behavior with different depressurizing approaches. The simulation resul...

for treatment of anti-nutritional factors(anfs), (?-n-oxalyl -l- ?, ? -diaminopropionic acid (?-odap) and condensed tannin (ct)) in grass pea, some such alkali treatments as naoh, nahco3, kmno4 and wood ash, besides water soaking and polyethylene glycol (peg) (6000 mw) were employed . metabolizable energy (me) of treated and of untreated grass pea was assessed using gas production technique, tw...
