摘要
实验以初生牛体重、奶牛产奶量、产奶品质为主要指标,对比不同紫花苜蓿草粉比例下,奶牛生产性能情况。通过本次试验对比发现,在奶牛饲养过程中,添加紫花苜蓿草粉比例不同对动物生产性能的影响也有所不同,其中奶牛体重、产奶量、产奶品质得到有益提升,经济效益也明显提升,证明紫花苜蓿草粉的营养价值对动物生产性能的优化影响。
During the experiment, the birth weight, milk yield and milk quality of dairy cows were used as the main indexes to compare the production performance of dairy cows under different alfalfa meal proportions. Through the test contrast found that in the process of dairy cattle breeding, adding alfalfa grass meal proportion is different on the animal production performance is also different, the influence of weight of cows, milk yield, milk quality improved beneficial, economic benefits is improved significantly, proved that the nutrition value of alfalfa grass meal for animal production performance optimization.
