| 摘 要： | 在高、中、低(18.99、14.48、8.81MJ/d)3个不同能量水平饲养条件下,对36只杂交母羊(萨福克♂×小尾寒羊♀)的体重变化,黄体数及激素FSH、LH分泌情况进行了研究分析。结果表明:高能量组的试验羊平均日增重比低能组和中等能量组分别提高235.5g(/(只·d)(P<0.05)、70.6g(/只·d)(P<0.05),黄体数分别增加81.3%(P<0.05)、43%(P>0.05)。同时,低能量组FSH、LH激素水平高于中等能量和高能量组,说明日粮能量水平影响母羊卵泡发育,排卵及黄体形成。 |

| Abstract: | The changes of weight,corpus luteum number and secretion of FSH,LH of 36 crossbred ewes(Black-Suffolk♂×Small Tail Han Sheep♀)were analysed under high,middle,low three different energy levels(18.99,14.48,8.81 MJ/d).The results showed that average daily weight gain in the high energy group was higher than that in the other two groups by 235.5(P < 0.05)and 70.6 g/d(P < 0.05);the number of corpora lutea in the high group was more than that in the two groups by 81.3%(P < 0.05)and 43%(P > 0.05),respectively.Meanwhile the quantity of the secretion of follicle stimulating hormone(FSH)and luteinizing hormone(LH)in the middle and high energy group were lower than those in the low ones.These results indicated that the different energy levels in the diet had the influence on the development of follicle,ovulation and the form of corpus luteum. |
