中文摘要:

      [目的]研究杏鲍菇菌糠对西门塔尔杂种肉牛生长性能和经济效益的影响。[方法]选择生长期西门塔尔杂种肉牛60头，分为2组，分别饲喂全混合日粮和替代青贮玉米全混合杏鲍菇菌糠日粮，试验期50 d，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，对照组和试验组采食正常，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2.29元/（头·d），差异显著（P<0.05）。[结论]杏鲍菇菌糠替代部分粗饲料饲喂生长期西门塔尔杂种肉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 performance of Simmental hybrid beef cattle. [Method] 60 Simmental hybrid beef cattle were divided into 2 groups in a randomized experiment design with the treatment period of 50 d. Conventional TMR without mushroom bran was designed to make the feeding control group and TMR with mushroom bran was experiment group. The growth indexes such as feed intake, the height and length of the daily and body length traits were measured and the economic benefits were analyzed. [Result] The results showed the food intake of the control group and the experimental group was normal, and there was no significant difference between the two groups (P>0.05). There was no significant difference between growth performance indexes (P>0.05). The feed cost of the treatment group reduced by 2.29 RMB/d (P<0.05) compared with the control group. [Conclusion] In the growing period, Simmental hybrid beef cattle were fed with mushroom bran instead of some roughage, which had no effect on their growth performance and significantly reduced the feed cost.
