Tо investigаte the effects оf prоgesterone priming on folliculаr wаve dynamics and its role in synchronizing ovulation in dairy cows undergoing timed artificial insemination (TAI) protocols. Objective 1: To examine the influence of progesterone priming on follicular wave emergence and dominance in cycling and anovular dairy cows. Hypothesis 1: Progesterone priming will regulate follicular wave emergence, ensuring the selection of a dominant follicle capable of ovulation during TAI. Objective 2: To evaluate the effects of progesterone levels on estradiol production and LH surge timing in cows subjected to TAI protocols. Hypothesis 2: Optimal progesterone levels will enhance estradiol production and synchronize the LH surge, improving ovulation timing and TAI success rates. Objective 3: To assess fertility outcomes, including conception and pregnancy rates, in cows receiving progesterone priming compared to unprimed controls. Hypothesis 3: Progesterone priming will improve conception and pregnancy rates by enhancing follicular readiness and optimizing ovulatory responses. References: Bó, G.A., & Baruselli, P.S. (2014).
