Abstract
The aim of the present study was to test the hypothesis of wave pattern of follicular growth and to monitor the ovarian follicular dynamic in Iraqi buffalo cows Reproductive tracts were collected at random intervals slaughtered at Mosul abattoir According to morphological appearance of the corpus luteum the estrous cycle was divided into four stages The number of subordinate follicle 5 mm in diameter was higher during stage 1 metestrous and stage proestrous and estrous than during other stages of the estrous cycles 135 ± 608 and 4 941 ± 394 respectively There were fewer follicles 5–8 mm in diameter during early diestrous and proestrous 166 ± 142 and estrous 069 ± 047 than during metestrous 453 ± 323 and late diestrous 366 ± 223 Follicles 8–12 mm in diameter were more numerous during early diestrous 162 ± 129 and late diestrous 103 ± 072 A total 38 646 82/127 animals examined showed follicles larger than 8 mm during early and late diestrous stage 2 and stage 3 This indicated that these buffaloes developed two follicular waves in their cycle Buffaloes did not show follicles larger than 8 mm during early and late diestrous were 45 animals 354 45/127 but all of these presented one large follicle during the following stage These buffaloes develop only one follicular wave in their cycle It could be concluded that 646 of Iraqi buffalo cows develop two patterns of follicular waves and 354 showed one wave of follicular dynamics
