麦秸微贮的营养价值及对育肥羊增重的效果分析

Nutritional Value of Wheat Straw Microstorage and Its Effect on Weight Gain of Fattening Sheep

该研究旨在评价麦秸秆微贮后营养价值及对育肥羊增重的效果,为充分利用麦秸资源提供理论依据。在麦秸中添加复合菌酶制剂,发酵后通过常规养分测定评定营养价值变化;通过饲养试验研究对育肥羊的增重效果。结果表明,麦秸秆经微贮处理后粗蛋白质、粗灰分分别提高1.18%和2.82%;干物质、粗纤维比未处理的麦秸秆分别降低0.79%和7.38%。试验羊在同等饲养条件下,麦秸秆微贮+精料育肥羊60 d,多浪羊增重10.5 kg/只、山羊增重8.63 kg/只,较麦秸+精料多浪羊多增重2.58 kg/只、山羊多增重2.26 kg/只。麦秸经复合菌酶制剂发酵后,可有效提高其营养价值,改善育肥羊增重,增加养殖效益。

The purpose of this study was to evaluate the nutritional value of wheat straw after microstorage and its effect on the weight gain of fattening sheep,and to provide theoretical basis for the full utilization of wheat straw resources.The nutritional value of wheat straw was evaluated by conventional nutrient determination after fermentation by adding complex bacterial enzyme preparation.The weight gain effect on fattening sheep was studied by feeding experiment.The results showed that the crude protein and ash content of wheat straw were increased by 1.18%and 2.82%,respectively.Dry matter and crude fiber decreased by 0.79%and 7.38%compared with untreated wheat straw,respectively.Under the same feeding conditions,the experimental sheep were fattened with wheat straw microstorage and concentrate for 60 days,and the weight of Duolang sheep and goats increased by 10.5 kg/sheep and 8.63 kg/goat,which was 2.58 kg/sheep and 2.26 kg/goat more than that of wheat straw and concentrate Duolang sheep.It is concluded that wheat straw can effectively improve its nutritional value,improve the weight gain of fattening sheep and increase breeding efficiency after fermentation with complex bacterial enzyme preparation.
