农作物秸秆颗粒饲料特性分析及对奶牛产奶量的影响

Analysis of Characteristics of Crop Straw Pellet Feed and Its Effect on Milk Yield of Dairy Cows

本试验旨在研究农作物秸秆转化为高品质的颗粒饲料,实现资源的有效利用,将农作物秸秆加入精饲料和添加剂粉碎压制成颗粒秸秆饲料,充分发挥秸秆饲料的营养价值。加料量一般控制在的3%~6%,含水率14%~16%之间。农作物秸秆颗粒中加入5%左右的油脂、鸡蛋或糖蜜。颗粒直径一般在10~30 mm之间,可根据家畜而定,提高家畜的适口性及资源的利用价值。对农作物秸秆通过科学的加工处理,提高其应用价值,为畜牧业提供可持续的饲料来源,将县域内的农作物秸秆变废为宝。

The purpose of this experiment is to study the transformation of crop straw into high-quality pellet feed,to realize the effective utilization of resources,and to crush crop straw into pellet straw feed by adding refined feed and additives,give full play to its straw feed nutritional value.The feed rate is generally controlled between 3%-6%and moisture content between 14%-16%.About 5%oil,egg or molasses was added into straw granules of grass crops.Particle diameter generally in 10-30 mm,depending on livestock,can improve their livestock palatability and the use of resources value.Through scientific pro-cessing of crop straw,it can improve its application value,provide sustainable feed source for animal husbandry,and turn crop straw waste into treasure.
