Characteristics of ovarian follicular dynamics throughout the estrous cycle of Egyptian buffaloes.

Abstract Data of 56 normal and 9 abnormal estrous cycles were collected from 9 Egyptian buffaloes ( Bublus bublis ) to describe the follicular growth wave pattern. Heat was checked twice daily while, ovaries were scanned daily to monitor the patterns of follicular waves. Day of ovulation was determined when the largest follicle was replaced by corpus haemorrhgicum (CH). Number of waves/cycle, day of emergence of the follicular wave, characteristics of the dominant follicle and corpus luteum (CL) growth features were monitored. Buffaloes displayed mainly two types of follicular waves; two (46.4%) and three (53.6%). In cycles of three wave pattern, time of emergence of the 1st wave post-heat was longer ( P P P P
