This study aimed to investigate whether the variation (morning or afternoon) in the insertion of progesterone (P4) intravaginal device (IVD) affects embryo yield in locally adapted superovulated goats. A total of 16 Canindé and 22 Moxotó goats were equally assigned to two groups according to the time of insertion (G1:06:30 to 07:30 a.m. and G2: 06:30 to 07:30 p.m.) of the IVD containing 0.3 g of P4 (Eazi-Breed CIDR®; Pfizer, São Paulo, Brazil), which remained for six days. As expected for NSER performed 7 d after mating, the proportions of blastocyst were superior to morulae in both groups (P < 0.01). We concluded that the difference in the timing of IVD insertion does not affect the efficiency of embryo yield in locally adapted superovulated Brazilian goats.
