Effects of Different Treatments of Fodder Blocks of Maize Straw on Increases of Sheep

选用当年的小尾寒羊公羔 30 只,分成三组,每组 10 只。在基础日粮相同的条件下,第 1 组加入玉米秸粉,第 2 组加入玉米秸穰饲料块,第 3 组加入全玉米秸饲料块,进行 100d 育肥试验。试验结果是:第 1 组平均日增重为 242 g ± 9.0 g;第 2 组平均日增重为 262 g ± 38 g;第 3 组平均日增重为246 g ± 29 g。经方差分析,三个组别差异不显著( > 0.05)。

The experiment was conducted to study the effects of different treatments of fodder blocks of maize straw on the daily mean increases of sheep. Thirty male little -tailed cold sheep of that year were selected and equally divided into three groups. Fatten testhad beencarriedthrough about 100 days underthe foundation of the same basicration - powder of maize straw , fodder block of maize straw pulp and fodder block of whole maize straw were added in each group re- spectively. The result of the test showed: Average increase weight by day: 242 grams ± 9.0 grams in the first group; 262 grams ± 38 grams in the second group; 246 grams ± 29 grams in the third group, analysed by variance, there is little remarkable value p> 0.05 among three groups.
