| 摘 要： | 东北农牧交错区与牧区畜牧业生产不同,其中一个重要的不同点就是农牧交错区具有多种农副产品,这些农副产品在枯草期成为家畜丰富的干物质来源。而这些农副产品由于所含蛋白、纤维、口感等存在很大差异,因而家畜对其有不同的采食行为。对10种东北农牧交错区枯草期最主要的补饲物进行家畜采食行为的试验,为家畜的日常补饲及管理提供参考资料。结果表明:绿豆秸秆、葵盘、葵叶、羊草、玉米叶为补饲物的首选。

| Abstract: | There are a series of differences of ani mal production between agro-pasture area and pasturearea,included agro-pasture area has all kinds of by-product of crops.By-product of crops could be theDMsupplement of livestock.The content of CP,fibre of these supplements were different,and therewere different grazing behaviors in grazing these supplements.The experi mental result of this studywould give some basal reference to the management of livestock supplementation |
