棉花秸秆不同搭配比例饲喂肉羊试验研究

Experiment of Different Proportion of Cotton Straw for Feeding Meat Sheep

由于棉花秸秆的木质化程度较高,不做任何加工,直接饲喂羊,质地粗硬,适口性差,消化率低、浪费大。为此,我们以棉花秸秆为主（玉米秸秆、小麦秸秆）进行了铡短粉碎、清水滤净等加工处理,并按照20%-50%的比例添加棉花秸秆,搭配精料,进行了三个月的饲喂肉羊试验。试验表明：棉花秸秆等饲草通过铡短粉碎、清水滤净等加工处理,搭配少量精料,饲料成本低廉,养羊增重快,与对照组相比,平均日增重分别提高42.2%,40.8%,73%和51%,各试验组与对照组相比差异显著（P〈0.05）,其中试验三组生长速度最快,与对照组相比平均日增重提高73%,以此确定棉花秸秆搭配比例,在全市推广饲喂,可以大幅度提高棉花秸秆等饲草的利用率。

With high wood content in cotton straw,feeding cotton strow showed bad palpatable,low digestion,large waste without through any processing,Therefore,cotton strow with maize straw,wheat straw were processed by cutting,crushed,filtrated by water.In proportion of adding 20%～50% cotton straw,adding small amount of concentrate diet.Feeding experiment was carried out for three month,The result showed that such diet has good effect for body gaining of sheep.Comparing with controlling group,average daily body gaining increased by 42.2%,40.8%,73%and 51% respectively,There is significant difference between each experimental group and contrdling group（P0.05）,Adding 40% of cotton straw was ootimum,increasing by 73% of daily body gaining.
