In Vitro Fermentation Characteristics and Nutritive Value of Iranian Oil Seed Meals for Ruminants

This study was conducted to determine the chemical composition and estimating nutritive value of soybean meal, sunflower meal, rapeseed meal and cotton- seed meal using in vitro gas production technique. The experimental samples (200 mg DM from each) were incubated in vitro with rumen liquor taken from three canulated rams at 2, 4, 6, 8, 12, 24, 36, 48 and 72 h in three replicates. The results showed that there are significant differences between gas production values of samples at all incubation times (p rapeseed meal> cotton- seed meal> sunflower seed meal.
