%X a total of 60 adult female goats fed two supplements (concentrated commercial and concentrated with pigeon pea foliage) and two suckling systems (natural: raised without mother separation and artificial: supply of goat milk with artificial suckling and goat kids separated from the mother) were evaluated to determine resumption of ovarian activity and interval birth-conception in semi-intensive exploitations, according to a 2 x 2 factorial arrangement. supplementation with concentrate and the suckling system were the two factors, each with two levels, which were analyzed by mixed procedure (proc mixed) of sas statistical package. goats, with the natural or artificial suckling system showed a birth-conception interval of 169.4 vs 132.4 days, respectively, and goats kids weight was higher (p<0.05) 14.6 vs 12.8 kg, respectively, regardless of the type of food consumed.the early resumption of ovarian activity occurred earlier (p<0.05) in goats fed with commercial concentrate and whose goats kids were maintained with artificial suckling. the goats group consuming commercial concentrate showed of total weight losses of 1450 kg, while those who consumed concentrated with pigeon pea foliage lost 0150 kg, which corresponds to an increased average daily milk production (p<0.05) for goats consuming commercial concentrate (734.5 vs. 656.5 g). treatment with commercial concentrated food produced greater weight loss in goats (p<0.05) increased daily milk production, which could be due to a negative energy balance. the resumption of ovarian activity occurred with higher incidence (p<0.05) at 90 days in goats that were maintained with commercial concentrate and artificial suckling with respect to the group consuming the same food but their goats kids were maintained with natural suckling (40 vs. 6%). this situation leads to greater nutritional birth conception interval and a later restart of ovarian activity, which probably related to the negative stimulus of lactation on these para
