【摘要】 为了探索生态蚕业良性循环系统和开发新的畜牧饲料来源,给生猪饲喂含蚕沙的日粮,通过消化试验、饲养试验、屠宰分析等,确定蚕沙在育肥猪日粮中的最佳添加比例为7%。利用蚕沙喂猪可以降低饲料成本,平均每头猪增加盈利55元。综合试验结果认为:蚕沙富含蛋白质及多种矿物质,是营养丰富的饲料源;利用蚕沙养猪,既可提高蚕业生产综合经济效益,又可减少蚕沙对环境的污染。更多还原

【Abstract】 In order to explore the circulatory system of ecological sericulture and develop a new soure of animal forage,silkworm excrement was added in the daily feed of pigs and its best rate for fatten pigs was determined to be 7% based on experiments of digestion and raising and slaughter analysis.By utilization of silkworm excrement the cost of forage for pigs was reduced and the profit was increased by 55 Yuan per head in average.Thus a conclusion was formed based on the synthesizing of the experiments: Silkworm excrement containing plentiful protein and many kinds of mineral elements is one of abundant source of forage.Feeding pigs with silkworm excrements can not only increase the comprehensive economic benefit of sericulture,but also reduce the pollution of excrement to environment.更多还原
