Abstract:
In recent days, policy makers have opined to divert the research programmes in upstream areas of embryo transfer technology and such areas of research in the sphere was conservation of indigenous breeds of India. In order to accelerate the genetic conservation and improvement embryo biotechniques on Kangayam was undertaken. The study was conducted to determine the relationship between the antral follicular count (AFC) and superovulatory response in indigenous Kangayam cows. For the study a total of 12 Kangayam cows were used. The ovaries were examined ultrasonographically before the initiation, during the superovulatory treatment, before artificial insemination and on the day of embryo flushing. The number of small antral follicles of 3-6 mm in diameter in both the ovaries before superovulatory treatment was found to be significantly correlated with number of corpora lutea after superovulation, total number of embryos and number of transferable embryos recovered. The result of the present study indicated that the number of pre-antral follicular count could be used to predict the superovulatory response in indigenous Kangayam cows.
