Overall, females returned to estrus in intervals that
ranged from 17 to 76 days after mating, 35 of them
returning to estrus 17–24 days after mating and delayed
return to estrus (more than 24 days after mating) was
observed in 25 females. Table 1 shows the frequency
distribution of females with return to estrus according to
the occurrence or not of a previous reproductive failure.
The remating of females with a previous reproductive
failure resulted in 27.8% (10/36) of return to estrus
whereas 10.7% (50/469) of return to estrus was observed
in first service females. Females with a previous reproductive
failure had 3.2-times higher odds (P < 0.05) of
returning to estrus than first service females (Table 2).
