中文摘要:

      [目的]为研究杏鲍菇菌糠对9～12月龄生长期荷斯坦奶牛生长性能和经济效益的影响。[方法]选择9～12月龄生长期荷斯坦奶牛60头，随机分为2组，分别饲喂原日粮和添加杏鲍菇菌糠全混合日粮，试验期60 d，分别测定采食量、日增重、体高、体长等生长指标，并分析经济效益。[结果]结果表明，菌糠饲料适口性好，试验组采食正常，两组间采食量无显著差异（P>0.05）；生长性能指标间无显著差异（P>0.05）；试验组饲料成本较对照组减少5.87元/（头·d）。[结论]杏鲍菇菌糠替代部分粗饲料饲喂9～12月龄生长期荷斯坦牛对其生长性能无影响，且显著降低饲料成本，具有现实推广价值。

英文摘要:

      [Objective] This experiment was conducted to evaluate mushroom bran on growth performance and economic benefit of the 9-12-month-old Chinese Holstein heifers. [Method] Sixty 9-12-month-old Chinese Holstein heifers were divided into 2 groups randomly and they were raised the original diet and the whole mixed diet with dsytzc edodes bran, respectively. During the experimental period of 60 days, growth indexes such as feed intake, daily weight gain, body height and body length were measured, and economic benefits were analyzed. [Result] The results showed that mushroom bran had better palatability. The feed intake of treatment group was normal and did not differ from the control group (P>0.05); and there was no significant difference on the growth performance indexes (P>0.05). The feed cost of the treatment group reduced by 5.87 yuan (head·day）(P<0.05) compared with the control group. [Conclusion] Feeding Holstein Heifers at the growth stage from 9 to 12 months had no effect on their growth performance, and significantly reduced the feed cost, making it valuable to promote in reality.
