An experiment was conducted to evaluate the effects feeding in Cajamarca Black Creole sows on reproductive performance. Sows (24 nulliparous) were assigned randomly within to 2 treatments and maintained on these treatments for up to 2 reproductive cycles. A Sows group were fed with concentrated feed (CON) and the other group with restaurant food waste (DAR), from 5 months of age, during gestation, lactation and weaning-to-mating interval and were housed either in individual pens. Sows fed DAR had smaller (p< 0.05) weaning litter weight (40.33 vs. 45.72 kg) and had more (p< 0.05) piglets dead in lactation (4.2 vs. 1.7) than sows fed CON. Sows of first parity tended to farrow litters with less weight (born alive, 8.4 vs. 9.3 kg; p< 0.10) and had fewer pigs at weaning (6.7 vs. 7.5; p< 0.10) compared with second parity sows. Body weight of sows weaning sows increase (p< 0.05) in the second reproductive cycle (82.4 vs. 86.0 kg). Sows fed DAR produced fewer (p< 0.05) body weight in mating (85.0 vs. 90,0 kg) and had less body weight at weaning (81.2 vs. 87.2 kg) over 2 reproductive cycles compared with sows fed CON. Sows fed CON had better weaning-to-mating interval (p< 0.05) (7.8 vs. 8.9 d). In conclusion, feeding of DAR decreased litter weight at weaning, body weight and weaning-to-mating interval of sow but did not affect litters size, and generates a greater economic benefit in relation to use of concentrated feed in creoles sow.
