Assisted reproduction has been used to optimize reproduction in goats. Ultrasound technology has resulted in a definite gain of knowledge in terms of ovulation time. The aim of this study was to evaluate if the shift (morning or afternoon) of hormonal administration affects different reproductive parameters. This study was conducted from October to December (nonbreeding season) of 2005, in Piau/MG (21°35?S latitude and 43° 15?W longitude), Brazil. Eighteen nulliparous (n = 9) or pluriparous (n = 9) Toggenburg goats were assigned equally according to body weight and condition score into two treatments. Animals received intravaginal sponges (60 mg of MAP, Progespon®, Syntex, Buenos Aires, Argentina) for 6 days plus 37.5 (igof cloprostenol (Prolise®, ARSA S.R.L., Buenos Aires, Argentina) latero-vulvar and 200 IUeCG (Novormon® 5000, Syntex) i.m. 48 h before sponge removal. Procedures were done early in the morning for T1 (10 h) and later in afternoon for T2 (17 h). Goats were monitored twice daily to identify estrous onset and its duration. After sponge removal, ultrasound evaluations were performed every 8 h until ovulation to determine the time, number of ovulations, and ovulatory follicle diameters (5-MHz transducer; Aloka, SSD 500®, Tokyo, Japan). Statistical analyses were performed using all tests at the 95% confidence interval with a SAEG® program (Funarbe, Viçosa, Brazil). The results are presented as mean ± SD. The interval (h) from sponge removal to estrous onset was 30.7 ± 10.6 (T1) and 34.3 ± 17.6 (T2), whereas its duration was 33.3 ± 22.3 (T1) and 34.3 ± 22.4 (T2) (P > 0.05). The interval (h) from sponge removal to ovulation was 54.4 ± 10.2 (T1) and 53.4 ± 12.3 (T2) (P > 0.05). Also, the interval (h) from estrous onset to ovulation was 26.8 ± 8.7 (T1) and 18.1 ± 26.3 (T2). No difference (P > 0.05) was observed in the number of ovulations forT1 (1.89 ± 0.93) or T2 (1.89 ± 0.60). The diameter of the ovulatory follicle (mm) was similar (P > 0.05) for T1 (8.4 ± 1.28) and T2 (7.36 ± 1.15) (P > 0.05). A negative correlation was detected between the interval to estrous onset and diameter of the largest follicle (r = -0.41; P < 0.05), as well as between the interval to estrous onset and the interval from estrus to ovulation (r= -0.73; P < 0.001). A positive correlation was registered between the interval from estrus to ovulation and diameter of the largest follicle (r = 0.65; P < 0.001) and also between the interval from sponge removal to ovulation and diameter of the largest follicle (r = 0.51; P < 0.005) that was evident, indicating that follicles get larger with time. Finally, a negative correlation (r = -0.88; P < 0.05) was obtained between number of ovulations and average diameters of ovulated follicles. These data suggest that Toggenburg goats have a synchronization of ovulation when receiving progestagen short-term protocols in the nonbreeding season, independent of the hormonal dispensing shift.
