日粮能量水平对塞北乌骨鸡促性腺激素分泌的影响

Effects of Diet Energy Level on FSH,LH of Serum in Saibei Meat-type Silkies

为研究日粮能量水平对塞北乌骨鸡血清促性腺激素分泌的影响,试验选60只30周龄体重相近、来源相同、产蛋性能相似的塞北乌骨鸡,随机分为5组,每组3个重复,每个重复4只鸡。试验1组为对照组,饲喂基础日粮;试验2～5组分别饲喂能量降低5%和10%及提高5%和10%日粮。采用放射免疫分析方法(RIA)测定血浆促卵泡素(FSH)和促黄体素(LH)。结果表明,试验结束时,与试验1组相比,试验2组FSH含量差异极显著(P<0.01);试验2组与试验1、3、4、5组组间LH含量差异极显著(P<0.01)。提示,能量通过促性腺激素分泌影响生殖性能。

In order to study the effects of diet energy on follicle-stimulating hormone （FSH） and luteinizing hormone （LH） of serum in Saibei meat-type silkies, selected 30 week of 60 Saibei meat-type silkies with similar weight, same source, and egg production performance, and dividied into five groups by energy level, the test 1 group was the control group, fed with the bas- al diet, the test 2 to 5 groups fed with the energy reduced by 5~ and 10G and increased by 5G and 10G diet, respectively. By adopting the method of radiation immunity analysis （RIA） determinated serum FSH and LH. The results showed that at the end of the experiment, compared with the control group, the FSH content of test 2 group was significantly different （P~ 0.01）, the LH content between the test 2 group and the test 1, 3, 4, 5 groups were significantly different （P%0.01）. It indi- cated that energy by gonadotrophin secretion affected reproductive performance.
