摘要
全株玉米青贮饲料(WPCS)作为反刍动物粗纤维和能量的主要来源,自2015年来,中国政府一直鼓励各省份生产全株玉米青贮饲料.适宜当地种植品种的选择与繁育、添加剂的使用、收割时间的控制及种植密度等都会提高全株玉米青贮养分含量,肉牛采食WPCS可影响其瘤胃发酵参数、生长性能、营养物质消化率等,为肉牛养殖综合效益的提高提供一定技术支持.
Abstract
Whole plant corn silage(WPCS)as the main source of crude fiber and energy for ruminants,and since 2015,China government has been encouraging all provinces to produce whole plant corn silage.Selection and breeding of varieties suitable for local planting,additives,harvest time and planting density,etc all will increase the nutrient content of whole plant corn silage,feeding WPCS on beef cattle can affect rumen fermentation parameters,growth performance,nutrient digestibility,etc,it provides some technical support for improving the comprehensive benefit of beef cattle breeding.
