Comparative Biometrical and Follicular Study in Pig Ovary

Abstract

Porcine ovaries are a biological material frequently used in studies that analyze follicular development processes, oocyte maturation in close connection with the stages of the estrus cycle. Ovarian follicles and their degree of development represent the point of departure in obtaining good quality oocytes, capable of being used in in vitro fertilization processes. The present study aims to identify the possible correlations between some biometric parameters and the degree of development of the follicles in the ovaries of pigs harvested after slaughtering the animals. The study was carried out on a number of 36 ovaries from 2 slaughters that were carried out in different stages of the estrus cycle, grouped into two experimental groups. In the laboratory, 3 biometric parameters weight (g), length (mm) and width (mm) were determined, respectively they were identified, photographed, numerically quantified and analyzed to establish the type of ovarian follicle. Based on the determinations made, we can conclude that the number of follicles and their type is changed in the ovaries of the two experimental groups, these two parameters are closely related to the stage of the estrous cycle and do not cause significant changes in the biometric parameters studied - weight, length, width.
