中文摘要:

      [目的]为研究发酵杏鲍菇菌糠营养价值和对肉牛的饲喂效果。[方法]本研究选取20头6-7月龄雄性日本和牛三代牛并按试验要求随机分为3组,分别饲喂3种不同饲粮,以牛场TMR日粮为对照组(n=6),组Ⅰ(n=7)、组Ⅱ(n=7)分别在TMR日粮中添加发酵杏鲍菇菌糠、新鲜杏鲍菌糠替代30%精料,预饲期7d,正试期70d,检测各组营养水平、肉牛生长性能、血液生理生化指标进行考察。[结果]发酵杏鲍菇菌糠粗蛋白含量和综合净能为11.21%、4.85 MJ/kg,新鲜杏鲍菇菌糠粗蛋白含量和综合净能为10.75%、3.48 MJ/kg。组Ⅰ日增重水平高于组Ⅱ,低于对照组,三组差异不显著(P＞0.05)。组Ⅰ总蛋白(TP)、球蛋白(GLO)水平显著高于对照组(P ≤ 0.05),白蛋白(ALB)显著高于组Ⅱ(P ≤ 0.05),其他指标差异不显著(P＞0.05)。[结论]发酵处理提升了杏鲍菇菌糠的营养价值和风味,并且饲喂效果良好,可作为优质替代饲料用于肉牛饲养。

英文摘要:

      _{:【Objecttive】To study the nutritional value of fermented Pleurotuseryngii and the effect of feeding beef cattle.【Method】In this study, 20 male Japanese cattle of 6-7 months old were selected and randomly divided into 3 groups according to experimental requirements.Three different diets were fed, and the TMR diet of the cattle farm was used as the control group (n=6). In group I (n=7) and group II (n=7),the fermented Pleurotuseryngii sputum and the fresh Pleurotuseryngiisputum were replaced by 30% concentrate in the TMR diet. The pre-feeding period was 7 days, and the trial period was 70 days. The nutritional levels of each group,the growth performance of beef cattle,blood physiological and biochemical indicators were examined. 【Result】The crude protein content and comprehensive net energy of fermented Pleurotuseryngii sputum were 11.21% and 4.85 MJ/kg,The crude protein content and comprehensive net energy of fresh Pleurotuseryngii sputum were 10.75% and 3.48 MJ/kg. The daily weight gain of group I was higher than that of group II,which was lower than that of the control group,and the difference between the three groups was not significant (P >0.05). The total protein (TP) and globulin (GLO) levels in group I were significantly higher than those in the control group (P ≤0.05), albumin (ALB) was significantly higher than group II (P ≤0.05), and other indicators were not significantly different. (P>0.05).【Conclusion】The fermentation treatment enhances the nutritional value and flavor of Pleurotuseryngii sputum, and it has a good feeding effect, can be used as a high quality alternative feed for beef cattle breeding.}
