Abstract
Seasonal animal breeding is used to coordinate the time of birth with a suitable time of the year in terms of temperature and food availability. Small ruminants like goats and sheep are considered short-day breeders. Melatonin hormone has the main role in the regulation of seasonal breeding. Other hormones like Kisspeptin, gonadotropin inhibitory, and thyroid hormone have remarkable roles in this field. This article aims to study the functioning mechanism of the nervous and endocrine systems in regulating the reproductive activities of small ruminants, which is useful information for professionals and farmers in farm regulation and management. They are essential. The following study is done in the form of a review. The findings in this field show that the nervous and endocrine systems modulate reproductive
