摘要:
为了研究外源瘦素对蛋鸡的能量代谢调控、瘦素受体基因表达的影响,选用25羽30周龄、体况相似的海兰褐商品蛋鸡,随机分成5组,每组5羽:Ⅰ组为自由摄食组;Ⅱ组为禁食对照组,注射瘦素稀释液(0.75%PBS-BSA);Ⅲ、Ⅳ、Ⅴ组为试验注射组,在第8至第10天注射瘦素,注射水平分别为50、200、400 μg/(kg·d)。结果表明:与Ⅰ、Ⅱ组相比,试验Ⅴ组采食量显著下降(P<0.05),试验Ⅲ至Ⅴ组的采食量分别为Ⅱ组的92.86%、89.89%、75.46%;Ⅱ组体质量相对于Ⅰ组极显著下降(P<0.01),相对于Ⅲ、Ⅳ组显著下降(P<0.05),其余各组间均无明显差异,其中试验Ⅱ至Ⅴ组蛋鸡的体质量分别为Ⅰ组体质量的92.25%、99.18%、98.53%、95.30%;与Ⅴ组相比,试验Ⅰ、Ⅱ、Ⅳ组的腹脂率差异显著(P<0.05),分别仅为Ⅴ组的58.98%、45.84%、58.71%,其余各组间均无明显差异;与Ⅰ、Ⅱ组相比,Ⅲ、Ⅳ、Ⅴ组葡萄糖含量差异显著(P<0.05),分别为Ⅱ组的72.64%、61.15%、59.59%,而试验Ⅱ组与Ⅰ组无显著差异;各组甘油三酯含量无明显变化,在各组之间差异不显著;试验Ⅰ、Ⅲ、Ⅳ、Ⅴ组肝脏OB-R基因表达量分别为Ⅱ组的35.19%、6.17%、7.41%、3.09%,试验各组之间OB-R基因表达量差异不显著。综上所述,瘦素对蛋鸡食欲具有抑作用,瘦素使蛋鸡采食量下降,表现为体质量降低,葡萄糖、甘油三酯含量、肝脏OB-R基因表达量随着瘦素注射量的增加呈下降的趋势。
