不同加工处理玉米秸秆对藏羊舍饲育肥效果的研究

Study on Processing of Corn Straw on Tibetan Sheep Breeding Fertilizer Effect

冬季草原牧草枯黄,产量低,营养成分低,是导致藏羊枯草期掉膘的主要原因。舍饲育肥是枯草期藏羊出栏的主要途径之一,用不同加工调制玉米秸秆对高寒牧区藏羊进行60d的错峰育肥效果试验研究。结果表明:Ⅰ、Ⅱ、Ⅲ组羊在60d试验期中总增重分别为10.8kg、10.4kg、8.3kg,Ⅰ组比Ⅱ、Ⅲ组分别高0.4kg、2.5kg,Ⅱ组比Ⅲ组高2.1kg;Ⅰ、Ⅱ、Ⅲ组藏羊的日增重分别为180g、173g、138g;Ⅰ、Ⅱ组藏羊增重率分别为30.4%和28.2%,比Ⅲ组分别高7.3和5.1个百分点。Ⅰ、Ⅱ组藏羊比Ⅲ组藏羊增重效果有显著的提高(P<0.05),其中Ⅰ组增重效果最好。

In winter, the grass withered, low yield, low nutrients, is the main cause of the weight loss period of Tibetan sheep. Fast fattening is one of the main ways of Tibetan sheep slaughter in dry season. Experiment on fattening 60 days on the alpine pastoral area of Tibetan sheep with different processing of corn straw. The results show that Ⅰ, Ⅱ, Ⅲ group of sheep during the 60 days period in total weight gain were 10.8 kg, 10.4 kg, 8.3 kg, group Ⅰ were increased 0.4 kg and 2.5 kg than group Ⅱ and group Ⅲ. Ⅰ, Ⅱ, Ⅲ group of Tibetan sheep weight gain were 180 g, 173 g, 138 g. Group Ⅰ, group Ⅱof Tibetan sheep weight gain rate were 30.40% and 28.2 %, compared with the group Ⅲ, increased by 7.3 and 5.1 percentage points. There was a significant increase in the weight gain of Tibetan sheep in group Ⅰ and group Ⅱ （P〈0.05）. Amongthem, the effect of weight gain of group Ⅰ was the best.
