摘要
禽蛋的主要营养都集中在蛋黄,而蛋黄在禽类体内由卵泡发育而来,形成过程分为多个阶段,主要包括前期卵母细胞的激活以及后期的卵黄快速沉积。从卵母细胞到成熟卵泡的发育过程中,需要吸收大量卵黄蛋白原(VTG)和极低密度脂蛋白(VLDL)等营养物质,以保障卵泡的正常发育,期间主要受到性腺激素、日粮以及相关通路的调节。文章阐述了家禽卵泡的发育过程、营养物质沉积、发育影响因素以及主要调控通路,为改善家禽生产性能奠定理论基础。
The main nutrition of eggs is concentrated in the yolk.While the yolk develops from the follicles,the forming process of follicles is divided into several stages,including the activation of oocytes and the rapid deposition of yolk.During the development from oocytes to mature follicles,a large amount of nutrients such as vitellogenin(VTG)and very low density lipoprotein(VLDL)are necessary to be absorbed to ensure the normal development of follicles.The process is regulated by gonadotropin,diet and related pathways.This review described the follicle development process,nutrient deposition,influencing factors and main regulatory pathways of poultry,which laid a theoretical foundation for improving the performance of poultry.
