Abstract
A total of n=159 Lusitano mares and n=309 reproductive cycles were analysed to model follicle sizes at the time of ovulation and reproductive success in dependency of several variables. Uterine oedema was found to correlate positively with probability of successful pregnancy (p<0.05). Follicle sizes at the time of ovulation are affected by treatment with hCG (p<0.05), with lower sizes found for treated mares. Follicle size at the time of ovulation correlates negatively with the mares’ age (p<0.05) (Pearson’s r = -0.168). This has implications for the way we monitor follicular growth and intervene in breeding, specific to the Lusitano breed, to accurately time artificial insemination
