不同营养水平日粮对杂交羔羊育肥效果的影响

Influence of Different Nutrition Diets for Hybrid Lamb Fattening

选择15只6月龄的杂交羔羊(欧拉藏羊♂×小尾寒羊♀×特克赛尔♂)随机分为3组,分别饲喂3个不同营养水平的育肥饲料配方,研究其对杂交羔羊采食量、体质量、体尺的影响,结果表明,营养水平较高的试验Ⅰ组和营养水平中等的试验Ⅱ组,在试验期羔羊日增质量分别达到273.33,249.00 g,较营养水平较低的试验Ⅲ组分别提高了34.32%和22.36%,且差异极显著(P<0.01);试验Ⅰ组、Ⅱ组杂交羔羊的胸宽与胸围都显著高于试验Ⅲ组(P<0.05);试验Ⅰ组、Ⅱ组比试验Ⅲ组分别多收入66.33,45.33元,且差异极显著(P<0.01)。试验Ⅰ组、Ⅱ组的育肥效果好于试验Ⅲ组。

Fifteen hybrid lamb （Euler Tibetan sheep ×Small-tail Han sheep 9× Texel ） at six months of age were chozen and randomly divided into three groups of 3 fattening feed formulas at three nutrition levels respectively. Measurements to the hybrid lamb feed intake, weight and body size was done. The results show that： high nutrition levels group Ⅰ and the medium level nutrition group Ⅱ, in the trial period the lamb daily gain were 273.33 g and 249.00 g respectively. The low level nutrition group m increased by 34.32% and 22.36% respectively and the difference extremely significant was（P〈 0.01 ）. In test group Ⅰ and Ⅱ, chest width and chest circumference were significantly higher than in group Ⅲ （P 〈 0.05 ）; The income of groupⅠ and Ⅱ were 66.33 Chinese yuan and 45.33 Chinese yuan more than group Ⅲ, and was extremely significant different（P 〈 0.01 ）. The fattening effect of group Ⅰ,Ⅱ are better than group Ⅲ.
