摘要
试验选择处于产奶高峰期的奶牛20头,随机分成两组,每组10头,试验组奶牛饲喂我们自己研制的奶牛 复合预混料.试验结果表明,试验组奶牛产奶量提高11.2％(p<0.05),单位产奶成本降低6.7％.
20 dairy cattle at high milk production was selected and random allotted into 2 trial groups. 10 dairy cattle in one experiment group were feeded with the compound - premix developed according to NRC standard and LS/T3409-1996 by us. The result shows that milk yield of the dairy cattle in experiment group increases 11.2% than control group(p<0.05). And the cost of comple-mental feed per kg milk production reduces 6.7%.
