Abstract/OtherAbstract:
This study aims to evaluate the ovulation rate and the presence of functional corpora lutea after treatment by three different protocols designed to cause superovulation in brown brocket deer. Six female received an intravaginal device containing 0.33 g of progesterone (CIDR(®) ) for 8 days, followed by 0.5 mg injection of estradiol benzoate at the time of insertion and 265 µg of cloprostenol at the time of removal. Afterwards, the hinds were divided into three groups (n = 2): Treatment A received injection of 600 IU eCG on Day 4 after CIDR(®) insertion; Treatment B received injection of 300 IU eCG at the same time; and Treatment C received injection of 250 IU FSH dissolved in PVP, also on Day 4 post-insertion. The treatments were crossed over with 44-48 day intervals after CIDR(®) removal, such that all the deer were submitted to all three treatments. The mean ovulation rate (Treatment A = 3.40±0.68, Treatment B = 1.40±0.24, Treatment C = 0.80±0.49), total ovarian stimulation (Treatment A = 4.80±1.02, Treatment B = 1.80±0.37, Treatment C = 1.40±0.60), and mean CL diameter (Treatment A = 7.33±0.76 mm, Treatment B = 3.94±0.19 mm, Treatment C = 2.18±0.49 mm) in Treatment A were significantly higher than the mean ovulation rates, total ovarian stimulation, and mean CL diameter in Treatments B and C. The mean fecal progesterone metabolites at the luteal phase in Treatment A (6,277.94±2,232.47 ng/g feces) was significantly different from Treatment C (1,374.82±401.77 ng/g feces). Thus, although fertility was not evaluated directly, Treatment A proved capable of induce superovulation in the species Mazama gouazoubira, presenting the greatest mean ovulation rates, with the formation of functional corpora lutea.
