文章旨在探究丁酸钠对肉牛生产性能、肉品质和肌肉抗氧化指标的影响.试验选择健康状况良好,体重一致[(328.74±24.15)kg]的两岁龄西杂肉牛192头,随机分为4组,每组6个重复,每个重复8头.对照组饲喂基础日粮,试验组在基础日粮中梯度添加3、6和9 g/kg的丁酸钠,预试期10 d,正试期88 d.结果显示:(1)生产性能方面,6和9 g/kg丁酸钠组肉牛末重显著提高4.56% 和3.23%(P<0.05);平均日增重显著提高7.96% 和6.96%(P<0.05);料肉比显著降低6.98% 和6.11%(P<0.05).(2)肉品质方面,添加6 g/kg丁酸钠组肉牛肌肉pH24 h显著提高(P<0.05),剪切力显著降低(P<0.05),大理石花纹评分显著提高(P<0.05),粗脂肪含量显著提高(P<0.05).(3)抗氧化方面,添加6和9 g/kg丁酸钠组肉牛肌肉Cu-Zn SOD、CAT活性显著提高(P<0.05),ROS含量显著降低(P<0.05);添加3~9 g/kg丁酸钠组肉牛肌肉丙二醛(MDA)含量显著降低(P<0.05).综上所述,6 g/kg的丁酸钠能有效增强肉牛肌肉抗氧化能力,改善肉质,并提高生长性能.
The effect of sodium butyrate on production performance,meat quality,and muscle antioxidant indicators in beef cattle
To explore the effects of sodium butyrate on the production performance,meat quality,and muscle antioxidant indicators of beef cattle. 192 two year old Western crossbred beef cattle with good health and consistent weight[(328.74±24.15) kg]were selected for the experiment and randomly divided into 4 groups,with 6 replicates in each group and 8 cows in each replicate. The control group was fed with a basic diet,while the experimental group received a gradient addition of 3,6,and 9 g/kg sodium butyrate to the basic diet. The pre trial period was 10 days,and the trial period was 88 days. The results showed that:(1) in terms of production performance,the 6 and 9 g/kg sodium butyrate groups significantly increased the final weight of beef cattle by 4.56% and 3.23%(P<0.05);The average daily weight gain significantly increased by 7.96% and 6.96%(P<0.05);The feed to meat ratio significantly decreased by 6.98% and 6.11%(P<0.05).(2)In terms of meat quality,the addition of 6 g/kg sodium butyrate significantly increased the pH 24 hours of beef muscle(P<0.05),significantly reduced shear force(P<0.05),significantly improved marbling score(P<0.05),and significantly increased crude fat content(P<0.05).(3)In terms of antioxidant activity,the addition of 6 g/kg and 9 g/kg sodium butyrate resulted in Cu Zn SOD in beef muscle CAT activity significantly increased(P<0.05),The ROS content significantly decreased(P<0.05);The addition of 3-9 g/kg sodium butyrate significantly reduced the MDA content in beef muscle(P<0.05). In summary,6 g/kg sodium butyrate can effectively enhance the antioxidant capacity of beef cattle muscles,improve meat quality,and enhance growth performance.
