Intravaginal progesterone device (1.9g) and estradiol benzoate for follicular control in the mare during spring and summer

ABSTRACT The objective of this study was to evaluate follicular growth and ovulatory rates in mares treated with an intravaginal progesterone device (P4) during the 10-day period, associated with the use of estradiol benzoate (EB). The results were compared during the transition period (ET) in the spring and the breeding season in the summer (ER). The variables were submitted to ANOVA (Tukey's test), considering P摘要 本研究旨在评估为期10天疗程中，联合应用苯甲酸雌二醇（estradiol benzoate, EB）与阴道内孕酮装置（intravaginal progesterone device, P4）处理的母马的卵泡生长与排卵率。分别于春季过渡期（transition period, ET）与夏季繁殖季（breeding season, ER）对实验结果进行对比分析。采用方差分析（ANOVA，Tukey检验）对各变量进行统计处理，以P为考量依据。
