饲用甜菜块根混贮饲喂荷斯坦牛的试验研究

采用75%切碎的饲用甜菜根茎与15%芦苇草粉、8%棉籽壳及2%玉米粉进行混合青贮,并替代荷斯坦奶牛常规日粮中的部分玉米青贮,进行饲喂对比试验。结果表明,饲用甜菜混贮饲料干物质含量为27.8%、粗蛋白含量为2.76%、粗脂肪含量为0.92%、粗纤维含量为11.28%、粗灰分含量为3.23%、钙含量为0.10%和磷含量为0.04%。饲用甜菜混贮饲料等量替代10kg奶牛日粮中的玉米青贮饲喂奶牛,试验组比对照组每头奶牛日平均产奶量降低0.09kg,试验末期对照组和试验组的乳蛋白率分别为3.17%和3.18%,乳脂率分别为3.66%和3.73%,分析结果表明,产奶量及乳品质差异均不显著。可见饲用甜菜块根混贮是一种较好的饲料,可以替代玉米青贮饲喂奶牛,混贮是饲用甜菜块根一种理想的贮藏方法。

The Study of Mixed Storage with Fodder Sugarbeet Roots Fed Holstein Cows

The use of chopped fodder sugarbeet roots 75% and 15% reed meal,cotton seed 8% and 2% corn meal were mixed storage,and replacement Holstein cows part of regular diet of corn silage,compared to feeding test.The results show that the mixed fodder sugarbeet 27.8% dry matter in feed storage,crude protein 2.76%,crude fat 0.92%,crude fiber 11.28%,crude ash 3.23%,calcium 0.10% and phosphorus 0.04%.Equal amount of mixed feed,fodder sugarbeet storage alternative 10kg maize silage in dairy cow diets,feeding cows,the experimental group the average daily milk production per cow was 0.09kg lower than the control group,the control group and experimental group the milk protein rates were 3.17% and 3.18%,milk fat 3.66% and 3.73% respectively at the end of testing.The results show that milk production and milk quality were not significant.Mixed storage with fodder sugarbeet roots can be seen as a good feed and can alternative corn silage.Mixed storage with fodder sugarbeet roots is an ideal storage method.
