柠条饲料化技术及应用

Feed Processing Technology and Application of Caragana

柠条饲料合理开发利用可以拓宽干旱沙区饲料资源,缓解草原压力,改善生态环境。研究结果表明:柠条经过粉碎制粒后饲喂家畜,其利用率提高50%,家畜采食量增加20%～30%,增重提高15%左右;氨化处理后粗蛋白提高60.1%,纤维素降低5%,木质素降低1.8%;在氨化的柠条青贮饲料中添加5%玉米,粗蛋白提高64.2%,纤维素降低22.26%,木质素降低4.8%;青贮处理后粗蛋白提高0.7%,纤维素降低9.9%,木质素降低10.2%;微贮后粗蛋白增加6.6%、纤维素降低6.1%。通过以上处理可以提高柠条饲料营养价值和消化利用率。

The reasonable development of caragana feed could increase the feed resources and alleriate the steppe pressure and improve the ecosystem environment in dry sand area.The results of different processing methods in caragana feed showed that the utilized coefficient of caragana increased 50%,the appetite and weight of the domestic animal increased 20%～30% and 15%,respectively by smashing.The CP content increased 60.1%,the CF and the ADL decreased 5% and 1.8%,respectively in the ammoniated caragana silage.After adding 5% corn in the ammoniated caragana silage,the CP increased 64.2%,the CF and the ADL decreased 22.26% and 4.8%,respectively.After fermenting,the CP increased 0.7%,the CF and the ADL decreased 9.9% and 10.2%,respectively.After microbial silage,the CP increased 6.6%,the CF decreased 6.1% in caragana feed.
