摘要
为了减少天祝高寒牧区藏羊冷季掉膘损失,本试验于2013年12月1日-2014年5月15日在天祝县抓喜秀龙乡高寒牧区开展藏羊补饲燕麦秸秆青贮料和精料试验,分析了藏羊增重和经济效益的影响。结果表明,放牧+精料+青贮饲料试验组比放牧+精料对照组体重平均少减少4.39kg/只,。平均每只试验组藏羊比对照组多增收124.2元。说明在高寒牧区,青贮饲料的饲喂可以有效缓解冬春季藏羊掉膘的问题。而且,在饲喂青贮料后生产效益显著提高,也为当地牧民带来更多收入。
In order to reduce the body weight loss of Tibetan sheep in alpine pasture cold seasons,the Oats silage and concentrate were supplemented to feed Tibetan sheep in Tianzhu county from Dec.2013 to May 2014.The changes of body weight and economic benefit were analyzed.The results showed that the body weight loss of Tibetan sheep with grazing,feeding fodders and silage was less 4.39kg/sheep than that of grazing and feeding fodders,and the increase income of Tibetan sheep with grazing,feeding fodders was 124.2RMB Yuan.The study indicated that the silage can be used for feeding livestock in alpine pastoral land and it can reduce body weight loss in cold reasons.
