| Abstract: | The experiment was based on three Lezhi black emasculated goats fitted with rumen cannulas,which were used for the measurement of the degradability of the dry matter,crude protein and crude fiber in silkworm feces and several crude feedstuffs,such as corn straw silage,peanut vine,soybean straw,sweet potato vine and bean straw.The results showed that the degradability rate of the dry matter,crude protein and crude fiber within 72 hours in silkworm feces was 43.32%,45.47% and 36.05% respectively,the corn straw silage was 49.77%、54.67% and 20.70% respectively,the peanut vine was 43.00%,60.11% and 18.45%,the soybean straw was 31.91%,55.84% and 16.18%,the sweet potato vine was 50.72%,51.98% and 22.87%,and the bean straw was 32.97%,52.92% and 14.34%.In conclusion,the silkworm feces have high nutritional value and cheaper and can be used as goat feedstuff. |
