为研究青贮笋壳在奶牛生产中的应用效果，试验选用15头健康荷斯坦奶牛随机分成3组，即对照组、试验1组（6 kg青贮笋壳替代对照组日粮中1.5 kg的苜蓿干草）和试验2组（9 kg青贮笋壳替代对照组日粮中2.5 kg的苜蓿干草），进行为期60 d的饲养试验，其中预饲期10 d，正式期50 d。试验结果表明，试验1组产奶量较对照组和试验2组有所提高，但差异不显著（P＞0.05），试验1组4%标准奶产量则显著高于试验2组和对照组（P＜0.05）。试验1组乳脂率显著高于试验2组和对照组（P＜0.05），其他乳成分含量各试验组均较对照组有所改善（P＞0.05）。奶牛各项血清生化指标试验组和对照组间无显著差异，均处于正常生理范围。因此，青贮笋壳可以替代部分苜蓿干草在奶牛日粮中使用。

The experiment was conducted to study the effect of bamboo shoot scraps silage on production perfor-mance and biochemical index of dairy cattle.Fifteen Holstein cows were divided into three groups by random block design. cows of control group fed the basal diet.cows of 2 test groups were fed with diets adding 6 kg and 9 kg bamboo shoot scraps silage instead of 1.5 kg and 2.5 kg alfalfa of basal diet.The pre-trial period was 10 d ,the trial period was 50 d.The results showed that:the milk yield of group 1 was higher than that of group 2 and control group,but the differences was not remarkable.Both the milk fat content and 4% fat corrected milk of group 1 were significantly higher than those of group 1 and coutrol group.For serum biochemical indexes of cows,the differences of all group were not remarkable.The re-sults indicated that it was feasible to feed the cows with bamboo shoot scraps silage instead of some alfalfa.
