【摘要】：试验旨在研究本交笼养模式下不同笼层光照强度以及种鸡产蛋性能和蛋品质的差异,并进一步揭示其内在分子机制。53周龄的海兰褐父母代种鸡饲养于三层本交笼,分别测定各个笼层料槽口和笼内的光照强度、种鸡的产蛋性能、蛋品质及促卵泡素受体基因(folliclestimulating hormone receptor,Fshr)和促黄体素受体基因(luteinizing hormone receptor,Lhr)在下丘脑-垂体-性腺轴(hypothalamic-pituitary-gonadal axis,HPGA)的表达水平,整个试验持续30d。结果显示不同笼层光照强度以及相同笼层笼内和笼外光照强度存在差异(P0.05)。笼层对破蛋率和种蛋合格率以及蛋品质中的蛋壳颜色、蛋白高度、哈氏单位、蛋黄色泽有显著影响(P0.05),而对其它指标无影响(P0.05)。定量结果显示Fshr和Lhr在不同笼层种鸡HPGA的表达均差异不显著(P0.05)。试验结果表明,笼层是影响部分产蛋性能和蛋品质的重要因素。
[Abstract]:The purpose of the experiment was to study the difference of light intensity of different cage layers, laying performance and egg quality of broilers in this cage model, and to further reveal the intrinsic molecular mechanism of Hailan Brown broiler breeding broilers at the age of 53 weeks. The light intensity, egg quality, egg quality and the expression of follicle receptor gene (folliclestimulating hormone receptor and luteinizing hormone receptor gene (luteinizing hormone receptor in the hypothalamus-pituitary-gonadal axis (hypothalamic-pituitary-gonadal axis-HPGA) were measured. The whole experiment lasted 30 days. The results showed that there were significant differences in light intensity between different cage layers and between the same cage layer and outside cage (P0.05). Cage layer had significant effects on egg breaking rate and egg qualification rate, egg shell color, protein height, Hardy unit and yolk color in egg quality (P0.05), but had no effect on other indexes (P0.05). The quantitative results showed that there was no significant difference in the expression of Fshr and Lhr in HPGA of different cage layer broilers (P0.05). The results show that the cage layer is an important factor affecting the egg laying performance and egg quality.
