this study was carried out to investigate the effects of treated protein supplements with tannin extracted from pistachio by-product (p-pb) on in vitro gas production using fistulated sheep. one portion of p-pb was mixed with four portions of water for 48 h. the extracted product was sprayed on soybean meal (sbm) or canola meal (cm) with an equal ratio (1:1 v/w) and dried in the shade. the expe...

The objective of this study was to evaluate the in vitro effects of coconut materials on ruminal methanogenesis and fermentation characteristics, in particular their effectiveness for mitigating ruminal methanogenesis. Fistulated Holstein cows were used as the donor of rumen fluid. Coconut materials were added to an in vitro fermentation incubated with rumen fluid-buffer mixture and timothy sub...

ABSTRACT The aim of this study was to evaluate the effect exogenous amylase on gas production, in vitro dry matter digestibility (IVDMD), and digestion kinetics sorghum (Sorghum vulgaris) two corn hybrids different grain textures. Ruminal fluid collected from rumen-fistulated cows receiving or not (0.7g kg-1 (DM basis)), provided achieve 396 kilo Novo units for activity basis). Gas production m...

Effects of 3 ionophores and 2 antibiotics on in vitro H(2)S production, IVDMD, total gas production, and VFA profile with or without added S were examined. In Exp. 1, ruminal fluid from 2 ruminally cannulated steers fed a steam-flaked corn-based diet (75% concentrate) without ionophore and antibiotics for 28 d before collection was used to inoculate in vitro cultures. Treatments were control (n...

background: identifying the potential of livestock and forage plants of each region is a way to compensate the lack of forage, and efficient use of edible resources of the country. milk thistle is a medicinal plant which may be used as fodder for native livestock of khuzestan province. objectives: the purpose of this research was to study  the effects of different levels of milk thistle on rume...

Gas hydrates are a vast energy resource with global distribution in the permafrost and in the oceans. Even if conservative estimates are considered and only a small fraction is recoverable, the sheer size of the resource is so large that it demands evaluation as a potential energy source. In this review paper, we discuss the distribution of natural gas hydrate accumulations, the status of the p...

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 ...

The effects of exogenous fibrolytic enzymes (EFE; a mixture of two preparations from Trichoderma spp., with predominant xylanase and β-glucanase activities, respectively) on colonization and digestion of ground barley straw and alfalfa hay by Fibrobacter succinogenes S85 and Ruminococcus flavefaciens FD1 were studied in vitro. The two levels (28 and 280 μg/ml) of EFE tested and both bacteria we...

in this experiment, fermentation parameters of a tmr ration determined with different levels of phosalone as an organophosphate pesticide (0, 100, 250, 500, 750 and 1000 ppm) and bentonite (0, 1 and 2 %dm of tmr) using in vitro batch culture and gas production techniques. the results from gas production showed that cumulative gas production for 96h after incubation significantly decreased with ...

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...
