Lupins were treated by either heat (1158C for 1 h) or by formaldehyde (0.4 g 100 gÿ1 crude protein). The fractional rate of disappearance of N from dacron bags suspended in the rumen of steers was reduced by either treatment. Assuming a rumen outflow rate of 0.03 hÿ1, effective rumen degradability was 0.96, 0.94 and 0.92 for protein and 0.84, 0.82 and 0.81 for dry matter in untreated, heatand f...

Four Luxi beef cattle (400±10 kg) fitted with ruminal, duodenal and ileal cannulas were used in a 4×4 Latin square to assess the effects of soybean small peptide (SSP) infusion on rumen fermentation, diet digestion and flow of nutrient in the gastrointestinal tract. The ruminal infusion of SSP was 0 (control), 100, 200 and 300 g/d. Ruminal SSP infusion linearly (p<0.01) and quadratically (p<0.0...

maturation on stem quality may have the largest potential benefit. Declining cell wall degradability of alfalfa (Medicago sativa L.) The tools of molecular biology offer the potential of stems with maturation limits the nutritional value of alfalfa for ruminants. This study characterized changes in cell wall concentration, altering the development of alfalfa stems in very precise composition, a...

this study was conducted to investigate the effect of biological treatment withpleurotus floridafungi on chemical composition and rumen dry matter (dm) and organic matter (om) degradability of wheat and barley straw. wheat and barley straw were collected from golestan province of iran and after pasteurization mixed with fungi spawn (than 5% by weight). after 21 days samples were dried in oven (...

The effect of a homolactic inoculant containing a blend of Lactobacillus plantarum, Pediococcus acidilactici and Enterococcus faecium or, the anionic surfactant, sodium dodecyl sulphate (SDS), alone or in combination on fermentation characteristics, aerobic stability and in situ DM, OM and NDF degradability of barley silage was investigated. Barley (Hordeum vulgare, L.) was harvested (45% DM), ...

Ruminant feed evaluation systems use constant minimum requirements of rumen-degradable protein (RDP) and often relate this to apparently degradable organic matter (OM). However, studies with tropical forages indicate that RDP: apparently degraded OM might not be constant across high-fiber diets. This was tested with semi-continuous ruminal cultures (Rusitec) using dried contrasting low-protein ...

The experiment was carried out using fistulated multiparous Holstein Friesian crossbred (75% Holstein Friesian and 25% Red Sindhi) dairy cows in their dry period fed on untreated rice straw to evaluate the nutritive value of local protein feed resources using the in sacco method and in vitro pepsin-pancreatin digestion. Experimental feeds were cottonseed meal (CSM); soybean meal (SBM); dried br...

Taurine accounts for approximately 0.1% of an animal’s body. It cannot be used protein synthesis but plays a wide range important roles in the animal does not exist plants, while mammals can only synthesize 30–40% taurine they need. Supplementing to beef cattle may necessary improve their nutrient utilization and health status. However, no data are available regarding metabolism rumen. Two vitr...

four in vitro experiments (exp.) were conducted to evaluate lavender essential oil (leo) effects at 0 (control), 250 (low dose), 500 (medium dose), 750 and 1000 µl per l(high doses) of incubation medium on rumen gas production kinetics (exp.1), ruminal digestibility and fermentation (exp.2), methane production (exp.3) and rumen acidosis (exp.4). the asymptote of gas production (a) increased qua...
