Abstract
Two studies were conducted to determine reproductive performance (Estrus, EP, and gestation, GP) and ovarian activity (Follicle numbers, FN, and ovulation rate, OR) in goats (M) and does (P). In the first study, 28 P and 44 M females were treated with progesterone vaginal devices (Conipred-CO) and equine chorionic gonadotropin (eCG) doses of 0 (n = 11 P and 10 M), 200 (n = 11 P and 16 M) or 400 (n = 10 P and 14 M) IU. Dose of eCG affected EP in the P (45 to 90%) and the M (63 to 80%) goats, whereas GP was not affected in neither group (64 to 91% for P and 78 to 80% for M) of goats. In the second study, pubertal does were treated with Chronogest sponges and doses of 0, 100, 200 or 400 IU of eCG (n = 5). The eCG dose did not affect FN, values found were 13, 12, 11 and 11 follicles, respectively, for each dose; whereas, OR was greater (P<0.05) in the does treated with the 400 IU dose (2.87 ovulations), regarding the other doses (1.9 ovulations). eCG dose only affected EP, whereas, it had no effect on GP; in addition, eCG did not modify the FN, it is assumed that it only induces follicular growth, but, it did increase OR, in the highest eCG dose.

Key words: Estrous induction. Gestation. Goats. Ovarian follicles. Reproduction control.
