Breeding cycle is one of the main patterns of ecological animal husbandry development, but breeding cycle does not form a relatively closed cycle of endogenous resources. In recent years, forage value and ecological value of mulberry have made some progresses in different research areas and angles, but the thought and practice of both forage and ecological value of mulberry has not been systematically interpreted and researched. Based on the short board of animal husbandry development and the advan- tage of mulberry, animal husbandry and mulberry were complemented and fused, and relatively closed planting and raising ecological recycling pattern with mulberry as the axis was raised. Phased scientific research and production test data were obtained, and the problems and development suggestions were put forward in the following aspects : selection of mulberry varieties with both forage and ecological value, cost control of mulberry with both forage and ecological value, quality and safety control system of forage mulberry, orientation of feeding value of forage mulberry.展开更多
本试验旨在测定貉对5种常用动物性蛋白质饲料中粗蛋白质的消化率及有效能值。选取体重相近的健康公、母貉各30只,随机分为6组,每组10只(公母各占1/2),每个重复1只,单笼舍饲。6组貉分别饲喂基础饲粮和以20%(鱼粉、鸡肉粉或肉骨粉)或15%(...本试验旨在测定貉对5种常用动物性蛋白质饲料中粗蛋白质的消化率及有效能值。选取体重相近的健康公、母貉各30只,随机分为6组,每组10只(公母各占1/2),每个重复1只,单笼舍饲。6组貉分别饲喂基础饲粮和以20%(鱼粉、鸡肉粉或肉骨粉)或15%(血粉或酶解羽毛粉)待测饲料替代基础饲粮组成的试验饲粮。预试期7 d,正试期5 d。结果显示:公、母貉对上述5种动物性蛋白质饲料中干物质、有机物质和粗蛋白质的消化率及消化能和代谢能均无显著差异(P>0.05)。貉对鱼粉、肉骨粉、鸡肉粉、血粉和酶解羽毛粉的消化能分别为17.30、12.60、17.09、20.27和18.84 M J/kg,代谢能分别为13.94、10.38、14.44、16.05和15.10 M J/kg,粗蛋白质消化率分别为94.8%、80.7%、81.0%、92.6%和87.5%。由此得出,作为蛋白质饲料资源,貉对鱼粉中粗蛋白质的消化率最高,其次为血粉和酶解羽毛粉,对鸡肉粉和肉骨粉中粗蛋白质的消化率较低。展开更多
