A new apparatus, named Bang-Bang (BB), which can facilitate the in situ nylon bag measurement of ruminal degradation in beef cattle, is described. The BB is an apparatus specially designed as a replacement of the traditional steel chain or flexible plastic tubes for binding the bags used in the in situ nylon bag (ISNB) method. The BB apparatus consists of cylindrical pedestals, sealing clips, n...

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...

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...

Ruminal protein degradation of soybean meal and field pea were compared using 2 analytical methods: in situ and a laboratory analysis with a proteolytic enzyme extracted from Streptomyces griseus. The degradation of total nitrogen in nylon bags of the feeds was measured between 0 and 48 h in the rumen of 2 cows (theoretical degradability: 70.0% for soybean meal and 94.7% for field pea). Electro...

The current study evaluated the effects of electron beam (EB; 10, 20, 30 and 40 kGy), urea and NaOH treatments on chemical composition, phenolic compounds, in vitro gas production and i n situ ruminal degradability of pistachio by-product (PB). The EB decreased (p < 0.01) neutral detergent fiber (NDF), acid detergent fiber (ADF) and acid detergent lignin (ADL) contents of PB. Treating PB by NaO...
