I . In the first of two experiments four sheep were fed on dried grass and oat straw in the following combinations: ( I ) straw eaten to appetite and an equal quantity given via a rumen fistula, (2) straw eaten and grass by fistula, (3) grass eaten and straw by fistula, (4) grass eaten and grass by fistula. Mean daily dry-matter intakes (g/kg metabolic live weight, W0,75) for the four treatment...

The effect of the substitution of imported raw materials (corn and soyabeans) by local food resources (barley, white sorghum, triticale and horse bean) on the parameters of faciesfermentation and digestibility in the rumen of sheep was evaluated. Four Sicilo-Sarde rams 4.8±0.5 years of age with an average live weight of 45.25±3.5 kg, permanently canulated in the rumen and housed in individual c...

The study was carried out to find out the differences in the chemical composition of wheat straw obtained from three different regions of India, to compare their susceptibility to fungal degradation, and subsequently to evaluate the correlation between lignin loss and improvement in in vitro digestibility. Four Phlebia species were used to degrade different wheat straw samples during 30 days of...

In order to investigate the effect of different levels of niacin supplementation on growth, nutrient utilization, their balance and blood biochemical profile, 15 male buffalo calves (9-10 months of age, 88.4±4.37 kg average body weight) were divided into 3 equal groups each of 5 calves, following a completely randomized design, and fed individually for 120 days with wheat straw and concentrate ...

Energy digestibility in the growing pig increases with BW increase and may differ between breeds of pigs or between lines selected on criteria other than digestion. However, little is known about the variability in energy digestibility within a line or a breed of pigs, especially when fibrous diets are fed. For this purpose, 20 Large White castrated male growing pigs originating from four boars...

Dry matter and cellulose digestibility were not affected by the urea infusions. The apparent nitrogen digestibility, derived from the difference between feed and faecal N, and ignoring infused N, was slightly depressed by urea infusions of from 9 to 34 g N/day, but at the highest level of infusion (43.7 g N/day) it was equal to or greater than the control value. Rumen pH and VFA concentrations ...

Eight continuous culture fermenters were used in a completely randomized design to evaluate various nutritional values of Kochia (Kochia scoparia) compared with Atriplex (Atriplex dimorphostegia). Dried and pelleted samples (leaves and stems) provided substrate for metabolism by ruminal microbes maintained in a continuous culture fermentation system. Results indicated that there were no differe...

two experiments were conducted to evaluate the crude protein fractionation, in vitro gas production and the biological effects of tannins in alfalfa silage treated with different levels of pistachio by-products (pb) extract. pb was soaked in water with a ratio of 1:5 (w/v) for 12 h. after filtering and concentrating, the crude extract was added to fresh alfalfa to a final concentration of 1%, 2...
