Abstract

Ovarian morphometric characterization is an important data in livestock production that used to improve reproductive efficiency, predict fertility, and guide biotechnology applications such as multiple ovulation and embryo transfer. This study was conducted to establish ovarian structure characterization of Philippine Native and Upgraded goats. There are 50 samples collected from the slaughterhouse of ISU-CVSRRC, equally represented by each breed under study. After collection, the samples were kept in saline solution maintained at 36 C and transported to the laboratory The ovaries were dissected to evaluate parameters such as weight (g), length (cm), diameter (cm) and circumference (cm) of the ovary and number of dominant follicles. The analysis shows that between breeds, the mean difference in weight, circumference, and number of follicles significant (p < 0.05). On the other hand, the mean difference of parameters between the right and left ovary also varies within breed. Specifically in terms of length of ovary, the recorded mean varies significantly (p < 0.05) in upgraded does. On the number of follicles, it was noted that there is significant difference between breeds, noting that in Philippine native goats have more follicles in right ovary at 17.6 vs. 17.1 in left ovary; while in Upgraded goats, there are at least 15.9 follicles obtained in left ovary vs 15.4 in right ovary.
