摘要: 以3只安装永久性瘤胃瘘管的乐至黑山羊阉公羊为试验动物,采用尼龙袋法对蚕沙和青贮玉米秸秆、花生藤、大豆秸秆、红苕藤和豌豆秸秆等四川地区常见的几种粗饲料的干物质、粗蛋白和粗纤维的瘤胃降解率进行测定。结果表明,72h蚕沙的干物质、粗蛋白和粗纤维的有效降解率分别为43.32%、45.47%和36.05%,青贮玉米秸秆为49.77%、54.67%、20.70%;花生藤为43.00%、60.11%、18.45%;大豆秸秆为31.91%、55.84%、16.18%;红苕藤为50.72%、51.98%、22.87%;豌豆秸秆为32.97%、52.92%、14.34%。蚕沙价格低廉,营养价值高,可以作为山羊饲料。

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.
