The Phanerochaete chrysosporium (PC) and Pleurotus eryngii (PE) were observed for their potential to increase the in situ dry matter (DM) crude protein (CP) degradability of wheat straw. straw samples inoculated with PC PE fungi (10% weight/volum) incubated under solid state fermentation conditions at 30 ◦C days determine in-situ chemical composition. In ruminal was determined by using four can...

The objective of this study was to investigate in vitro effect of Malva sylvestris leaf extract (at 0, 25, 50 and 100 µL/30 mL of medium) on sheep ruminal cellulolytic and total viable bacteria growth, protozoa populations, methane production, neutral detergent fiber degradability (NDFD) and fermentation efficiency of oat hay. The addition of Malva sylvestris leaf extract at 25, 50 and 100 µL l...

Sixteen ruminally cannulated, English-crossbred heifers (378 ± 28.4 kg) grazing small-grain pasture (SGP) were used in a completely randomized design to evaluate effects of supplementing different amounts of corn dried distillers grains with solubles (DDGS; 0, 0.2, 0.4, and 0.6% of BW; as-fed basis) on forage intake, digestibility, and rumen fermentation characteristics. The experiment was cond...

The objectives were to characterize the effects of supplemental CP concentration and ruminal degradability in barley-based finishing diets on microbial protein synthesis, ruminal fermentation and nutrient digestion, and route and chemical form of N excretion in beef cattle. Four Angus heifers (564 ± 18 kg BW) with ruminal and duodenal cannulas were used in an experiment designed as a 4 × 4 Lati...

The aim of this experiment is to investigate the effects lactic acid bacteria and cellulase on fermentation quality, chemical composition, aerobic stability ruminal degradation characteristics mixed silage prepared with amaranth rice straw. Lactic were used as additives, four treatments follows: control group (CON, no additive), (LAB, additive amount was 5 mg/kg fresh matter), (CEL, 2 mg/kg) (L...

Bioavailability of three rumen protected Methionine (Met) sources with different protection methods (Mepron M85, Evonik Industries, Germany; Methioplus, Soda Nutrition, Italy and Methilock, Tehrandaneh Co. Iran) were evaluated in 2 experiments with 6 canulated non-lactating Holstein cows. In experiment 1, the ruminal in situ and mobile bag techniques were used for assessing ruminal degradabilit...

The aim of this experiment was to study the effect of breed (Churra and Merino) and advancing season (middle June, late July and early October) on rumen fermentation in sheep grazing a continuously stocked grass /white clover pasture. Six mature sheep (three Churra and three Merino) fitted with rumen cannulae were used. During each grazing period, samples of the grazed herbage (obtained using t...
