中文摘要:

      [目的]为了促进葡萄藤等葡萄副产物的饲料化利用，[方法]试验利用葡萄藤等葡萄副产物生产的颗粒饲料饲喂产奶期奶牛，研究其对奶牛产奶性能的影响。[结果]结果显示，试验期内，试验组奶牛产奶量随着试验时间延长而增加。在试验30 d时，试验组奶牛平均产奶量比对照组多2.1 kg，达显著水平（P＜0.05）；在试验结束时，比对照组多产奶2.4 kg（P＜0.05）。乳蛋白含量和乳脂率均有所增加，但未达显著水平（P＞0.05）。试验组奶牛日均增效益较对照组多2.26元。[结论]葡萄藤颗粒饲料可部分代替奶牛日粮中的玉米秸秆、玉米青贮等粗饲料，对提高奶牛产奶性能具有促进作用。

英文摘要:

      [Objective] In order to promote feed utilization of grape by-products. [Method] In this experiment, the granule feed produced by grape by-products, such as grapevine, was used to feed milk producing cows, and the effect of granule feed on milk producing performance of cows was studied. [Result] The results showed that in the experiment period, the average milk production of experiment group increased as experiment time extended. At 30 days, the average milk yield of experiment group was 2.1 kg more than the control group (P< 0.05). At the end of the experiment, the average milk yield of experiment group was 2.4 kg more than the control group (P< 0.05). The milk protein percentage and the milk fat percentage were increased, but no significant difference (P> 0.05). The average daily efficiency of experiment was 2.26 yuan more than the control group. [Conclusion] The grapevine pellet feed can partly replace the cornstalk and silage sorghum, which can improve the lactation performance of dairy cows.
