Ovarian status of Assam local goat from birth to six months of age

The local goat of Assam is a dwarf variety single or multicolored non-descript species. Its economic importance lies on its prolificacy, production of high quality meat and skin. The present study was conducted on twenty four healthy female Assam local goats from birth to six months of age including one control group. They were divided into eight age groups consisting of three animals in each group. The number of visible small Graafian follicles decreased but medium and large Graafian follicles increased with the advancement of age. Maximum number of oocytes recovered from medium types of follicles followed by recovery from large and small types. Most of the oocytes recovered from small and medium types of follicles were of A type whereas from large types were of C and N types. The mean diameter of all types of follicles, and their oocytes and nuclei increased with the advancement of age. The higher values in respect of physiological and histomorphological aspects, as recorded inthe higher age groups (5 to 6 months) could be utilized for induction of puberty and practiced in E.T.T. in this species of goat.
