TMR颗粒饲料对湖羊羔羊育肥的影响因素研究

Influencing factors on fattening of Hu sheep lambs with different Pelleted TMR

在养羊业中,传统的"精、粗分饲"或TMR散料(湿拌料)饲喂增重速度较慢,出栏周期长,为提高育肥羊的增重速度,缩短出栏时间,推广TMR颗粒饲料快速育肥技术意义重大。为研究湖羊羔羊颗粒饲料育肥的影响因素,本试验以常见的全株玉米青贮为基础的TMR散料为对照,针对目前江苏省市场上流通的3种颗粒饲料在3～5月龄育肥湖羊上进行对比试验,比较了料型、性别、剪毛等因素对湖羊羔羊育肥的影响。结果表明,3种颗粒饲料的增重效果明显优于TMR散料(P<0.05),母羔的日增重略低于公羔但差异不显著(P>0.05),剪毛对日增重和料重比无显著影响(P>0.05),含有木薯酒精渣、油糠等的Ⅲ组颗粒饲料育肥湖羊的效益最高。本试验为推广颗粒饲料育肥技术提供了参考依据。

Traditional "concentrate and coarse separately feeding"or TMR bulk feed(wet mix)has a less body weight gain and a longer fattening period.It is of great significance to promote the rapid fattening technology of pelleted TMR to increase the body weight gain of fattening sheep, shorten the fattening period.These trials were conducted to study the influencing factors of fattening Hu lambs with pelleted TMR,taking TMR bulk feed based on corn silage as control.The effects of feed type,gender and shearing on fattening Hu lambs with three kinds of pelleted TMR were investigated.The results showed that the body weight gain of three kinds of pellet TMR is obviously higher than that of TMR bulk feed(P<0.05).The average daily gain of female lambs was slightly lower than that of male lambs(P>0.05).The effect of shearing on daily gain and feed weight ratio was not significant.No.3 pelleted TMR containing Cassava alcohol residue and oil chaff has the best economic profit for fattening Hu sheep.This results provide a reference basis for popularizing fattening technology of pelleted TMR.
