In spite of these previous data, little is known about the expression of NKB and kisspeptin in the ovary of fowl. Information regarding the expression patterns of kisspeptin and NKB during the reproductive cycle and the relationships with estrogen remain scarce in the fowl. The goose is a commercially important food that is cultivated widely in China but the goose industry has been
hampered by high broodiness and poor egg laying perfor- mance, which are influenced by ovarian function (Xu et al.,
2014). Thus, the goal of the current study was to investi- gate the distribution of kisspeptin and NKB in the ovary and to assess the relationship between kisspeptin and NKB and estradiol in the serum of geese during reproductive cycle. The results that are presented here will help us pave the way for a better understanding of the role of kisspeptin and NKB in geese reproductive physiology.
