Abstract: To make full use of feed resources, we analyzed the main conventional nutrients of flax seed meal. Then we put flax seed meal into the rumen of Shanbei white cashmere goat fitted with permanent rumen fistula, and degradation rate of dry matter, crude protein and crude fiber in rumen were analyzed by using nylon bag method at 6, 12, 24 and 48 h. The results showed that content of crude protein, crude fiber, crude fat, ash, calcium and phosphorus in flax seed meal were 36.2%, 8.98%, 7.82%, 7.02%, 0.47% and 0.81%, respectively. Dry matter degradation rate was 55.11%, 78.75%, 78.77% and 85.75% in Shanbei white cashmere goat rumen at 6, 12, 24 and 48 h, respectively. Degradation rate of crude protein was 52.82% , 61.94% , 72.4% and 75.32%, respectively, and degradation rate of crude fiber was 23.9%, 25.1%, 26.2% and 28.6%, respectively. The results indicated that crude fat and crude protein content were relatively high in flax seed meal. Degradation rate of dry matter and crude protein could reach 78.77% and 72.4% within 24 hours, and Shanbei white cashmere goat had a good digestion of flax seed meal.
