Abstract | The objective to investigate the effects of the addition of UM3B on follicular dynamics profile after the second injection of PGF2α. Methods: In this experiment. A total of 20 Bali cows were used for this research. The average weights of the cow were 325-350±9.98 kg, cycling of estrus normally, and aged 3-5 years. All cows were divided into two treatment groups. The first group (n =10) was supplemented by UM3B dose of 350 g/head/day, and second group (n =10) was not supplemented with UM3B. The parameters were evaluated include of locations and sizes of the follicles, corpus luteum (CL) regression, and dominant follicles were assessed by a Ultrasonography (USG scan). Profile of estrus response after second injection PGF2α was observed manually. Results: Diameter of follicle ovulation, speed of follicle growth, length of the follicle growth phase, and follicular wave were significantly different (P<0.05) among group 1 and group 2. Whereas, the diameter of the follicle during injection, ovulation time, and estrus cycle length was not significantly different (P>0.05) among group 1 and group 2. While, the diameter of the corpus luteum during injection, diameter of corpus luteum during estrus, and speed of corpus luteum regression were not significantly different (P>0.05) between group 1 (with UM3B) and group 2 (without UM3B). Conclusions: The addition of UM3B could be improved by the diameter of follicle ovulation, speed of follicle growth, length of the follicle growth phase, and follicular wave in Bali cows.
