| Outline of Final Research Achievements |
he present study was identified Angiopoietin like proteins (ANGPTLs), which were involved in the follicle development during rapid growth stage of chicken ovarian follicles. ANGPTL5 mRNA expression was high level in the follicles at the rapid growth stage, and the function was clarified to play the role of the inhibitor on lipoprotein lipase activity. The injection of ANGPTL5 protein into laying hens enhanced the uptake of the egg yolk precursor to a follicle. Thus, the present results provide that ANGPTL5 is a novel target for efficient egg production in chickens.
