Sheep were fed once daily with 300 or 600 g dried perennial ryegrass (Lolium perenne) or white clover (Trifolium repens). Total rumen contents were sampled once daily at various intervals up to 24 h after feeding for 6 d. Total weight of fresh rumen contents and dry matter (DM), organic matter and particulate matter concentrations were measured and the particle size distribution of rumen conten...

this study was carried out to determine the effects of gamma irradiation on dry matter (dm) and on crude protein (cp) degradation of rapeseed meal, using nylon bags and sds-page techniques. ruminal nylon bags of either untreated or irradiated rapeseed meal at doses of 25, 50 and 75 kgy were suspended in the rumen of four non-lactating holstein cows for up to 48 h. intestinal crude protein diges...

degradation of dry matter (dm) and nitrogen (n) in fresh or frozen-thawed alfalfa and ryegrass was studied by using in situ technique. the forages were labeled with 15n during growth in a glasshouse, harvested at similar growth phase, and fresh (f) or frozen-thawed (ft) samples were incubated in the rumen of 3 sheep. there was no difference (p>0.05) between forage type (s) for the immediately s...

to study the chemical composition and qualitative comparison of the pistachio by-products and the effect of pistachio hull tannin on its digestibility and gas production, four experiments were carried out. in the first experiment, nutrient composition, phenolic and tannin components of the ohadi, kaleghuchi and white varieties of pistachio by-product from dehulling process were measured. pistac...

The aim of this study was to determine the chemical composition and in vitro digestibility, and to estimate the in vitro fermentation parameters of palm leaves and pedicels from Ghars palm variety. A rumen in situ technique was also used to examine In vitro Digestible Dry Matter (IDDM), In vitro Digestible Crude Protein (IDCP), and In vitro Digestible Neutral Fiber (IDNF), and rate and extent o...

The aim of this experiment was to investigate the beneficial effect monensin, tannic acid and cinnamon essential oil addition on sesame meal degradability by three-step in vitro method. experimental additives rumen, after rumen whole gastrointestinal tract significant (P<0.05). ruminal intestinal digestibility crude protein with range 76 84% 49 60%, respectively. increased (about 10%). Addit...

Eight rumen-fistulated steers were randomly assigned to mediumand high-concentrate diets supplemented with O, .75, 2.5 and 5% of either sodium bicarbonate or an artificial saliva salts mixture. Each animal was fed for 21 d at 75 g dry matter/kg body weight 'Ts. Rates of soybean meal (SBM) degradation were predicted by adjusting digestion rates in nylon bags with respective passage rates of chro...
