Resumen

ABSTRACT

Objective. To determine the effect of environmental factors on litter traits at birth and weaning, and their repeatabilities in four farms in the sub-humid tropics of Mexico. Materials and methods. Data from 46.249 to 50.316 litters for litter size at birth (LSB), number of piglets born alive (NBA), litter weight at birth (LWB), number of piglets weaned (NPW) and litter weight at weaning (LWW) were used. The statistical model for LSB, NBA and LWB included the effects of farm, farrowing year, farrowing season, parity number, simple interactions, random effects of sow and the error term. NPW and LWW were analyzed using the previous model plus the linear and quadratic effects of lactation length (LL). Results. The means for LSB, NBA, LWB, NPW and LWW were 11.7 piglets, 11.0 piglets, 16.1 kg, 10.3 piglets and 61.3 kg, respectively. All effects in the model affected the litter traits. Farrowing year x season interaction was significant for NPW, LWB and LWW. The dry season had the highest LSB, NBA y NPW. First parity sows had higher LSB and NBA means than for second parity sows. Parity increase until parity 4 to decrease thereafter. LL had a quadratic effect on NPW and LWW. Repeatability estimates for LSB, NBA, and LWB were 0.12, 0.12 and 0.14, respectively. Conclusions. All traits studied were influenced by the environmental factors studied. Repeatabilities for LSB, NBA and LWB were low.

 

RESUMEN

Objetivo. Determinar el efecto de factores ambientales sobre características de la camada al nacer y al destete, y sus repetibilidades en cuatro granjas en el trópico sub-húmedo de México. Materiales y métodos. Se utilizaron los datos de 50.316 a 46.249 camadas para el total de lechones nacidos (LSB), lechones nacidos vivos (NBA) y peso de la camada al nacimiento (LWB), lechones destetados (NPW) y peso de la camada al destete (LWW). El modelo estadístico para LSB, NBA y LWB incluyen los efectos de granja, año, época, número de parto, interacciones simples, efecto aleatorio de cerda y error. El modelo para NPW y LWW incluyó los factores anteriores y además, los efectos lineal y cuadrático de largo de lactación (LL). Resultados. Las medias para LSB, NBA, LWB, NPW y LWW fueron 11.7 lechones, 11.0 lechones, 16.1 kg, 10.3 lechones y 61.3 kg, respectivamente. Todos los factores estudiados afectaron las características de la camada. La interacción de año x época fue significativa para NPW, LWB y LWW. La época seca presentó las mayores medias de LSB, NBA y NPW. Las cerdas primer parto obtuvieron medias de LSB y NBA superiores que las cerdas del segundo parto. Las medias por número de parto incrementaron hasta el cuarto, para después disminuir. La LL obtuvo un efecto cuadrático sobre NPW y LWW. Las repetibilidades estimadas para LSB, NBA, y LWW fueron 0.12, 0.12 y 0.14, respectivamente. Conclusiones. Todos los factores ambientales estudiados afectaron las características de la camada al nacer y al destete. Las repetibilidades estimadas fueron bajas.
