The effect of essential oils (EO) of medical plant seeds and spices on rumen microbial fermentation of alfalfa hay, sugar beet pulp and barley grain (as substrate) were evaluated under in vitro conditions. In vitro incubations were carried out using the gas production method with glass syringes. Treatments were as follows; a control (no additive), monensin, EO of cinnamon, black pepper seed, cu...

This study was conducted to evaluate the possibility of alfalfa replacement with fenugreek hay for ruminants, using in vitro gas production parameters and some of rumen fermentation characteristics. For this propose, five different total mixed rations were formulated to meet nutrient requirements of 35 kg growing lambs with gradually replacement of alfalfa in control diet (T1) with different le...

In vitro fermentabilities of two mushrooms (Lentinus edodes--LenS; Tremella fuciformis--TreS), an herb (Astragalus membranaceus--AstS), and their polysaccharide fractions (LenE, TreE, and AstE) were investigated using microflora from chicken ceca. Polysaccharides were extracted using the hot water method. The mushrooms had lower polysaccharide yields (8 to 10%) than the herb (31%). Fermentation...

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...

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 objectives of this study were to partition corn grain into three digestible fractions and to measure the rate of disappearance of these fractions in vitro. Seventeen corn grain samples with varied fiber concentrations were extracted with either 80% ethanol or neutral detergent to obtain estimates of the pool size and digestion kinetics of the A, B1, B2, and C fractions. The carbohydrate sol...

the effect of eucalyptus (eucalyptus globulus labill;egeo) and angelica (heracleum persicum desf. ex fischer; hpeo) essential oils was assessed at the levels of 0, 3, 30, 300 or 3000 (µl 30 ml-1) on in vitro fermentation of buffered rumen fluid from 3 castrated male sheep. the fermentation kinetics were estimated after 54 hours incubation. the fermentation kinetic values, in vitro gas productio...

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 ...
