Resumen:
Mexicano (CNM). Se utilizaron Cerdos Pelón Mexicano (CPM) y Cuinos (CC), ambas razas CNM, criados en condiciones agro-pastoriles en el Estado de Nayarit, México. Se utilizaron 50 partos de CPM y 29 de CC sin observar diferencias para el total de lechones nacidos por camada (6,22), número de mortinatos (0,67), y de momificados (0,08), peso de la camada al destete (23,20 kg), y peso promedio del lechón destetado (5,28 kg), mientras que número y peso de lechones nacidos vivos por camada y peso promedio del lechón nacido vivo fueron más elevados en el CPM (6,04; 6,32 y 1,01, respectivamente); sin embargo, el CC destetó más lechones (4,95; p<0,01). No se encontraron diferencias, para las variables: edad al primer parto (547,65), días de gestación (113,38), días de lactancia (38,90), días de destete a servicio efectivo (11,19) e intervalo entre partos (159,06).
Descripción:
The reproductive performance of two breeds of Mexican Native Pig (MNP) was studied. Mexican Hairless Pigs (MHP) and Cuino Pigs (CP) which belong to the MNP, were raised under agriculturalgrazing conditions in the State of Nayarit, Mexico. Reproductive variables were measured in 50 farrowings from MHP and 29 from CP. No differences were recorded on, total pigs born/litter (6.22), number of stillbirths (0.67) and mummies (0.08), weaned litter (23.20 kg) and piglet weight (5.28 kg), but number and weisht of born alive/litter and piglet weight and, figures were higher for MHP (6.04, 6.32 and 1.01, respectively), but CP weaned more piglets (4.95; p<0.01). No differences were found for age at first farrowing (547.65), gestation (113.38) and lactating days (38.90), days from weaning to effective service (11.19), and interval between farrowings (159.06).
