Inclusion of fat in the diet of primiparous sows: effect on the reproduction and litter performance
Adding fat to sow diets may improve reproductive performance during the warm season. Therefore, the objective of this study was to evaluate the effect of fat addition at different levels on reproductive variables of primiparous sows in subtropical conditions. Three groups of six animals (n=18) were...

Therefore, the objective of this study was to evaluate the effect of fat addition at different levels on reproductive variables of primiparous sows in subtropical conditions. Three groups of six animals (n=18) were fed with three diets with different fat levels (0%, 3.5% and 7%) from day 90 of gestation until the end of lactation (21 days). Litter size, weight and number of piglets born alive and stillborn were recorded, as well as weight and number of pigs at weaning, along with weaning-to-estrus interval. Completely random design was used, and collected data were analyzed using Infostat® statistical software. ANOVA was used for means comparison. No differences between treatments were observed among number and weight of pig born alive, stillborn, litter size and weaning-to-estrus interval (p>0.05), whereas number and weight of pigs at weaning were increased by the addition of fat (p<0.05). In conclusion, fat inclusion resulted in an improved number and weight of piglets at weaning; however, weaning-to-estrus and variables at birth, were not affected. La incorporación de grasa en la dieta podría mejorar la performance reproductiva de cerdos en producción, principalmente durante las épocas más calurosas. Para comprobar esta hipótesis se evaluó el efecto de la inclusión de grasa a diferentes niveles sobre variables reproductivas de cerdas primíparas en condiciones de subtrópico. Se utilizaron 3 grupos de 6 animales (n=18) a los cuales se les suministraron 3 dietas con diferentes niveles de inclusión de grasa (0%, 3,5% y 7%) desde el día 90 de gestación y durante la lactación (21 días). Las variables medidas fueron el número de lechones nacidos totales, nacidos vivos, muertos y peso de la camada al nacimiento y al destete, mientras que sobre las hembras se registró el intervalo de retorno al celo. Se empleó un diseño completamente aleatorizado y los datos fueron analizados mediante ANOVA con el software estadístico Infostat®. No se encontraron diferencias al incorporar grasa, en relación al número de lechones nacidos vivos, muertos, totales, peso al nacimiento e intervalo-destete celo (p>0,05) mientras que el número y peso de lechones al destete se vio influenciado de manera significativa (p<0,05). En conclusión, la adición de grasa en dietas de cerdas primíparas no afecta variables al nacimiento ni el intervalo detete-celo, pero mejora el número y peso de los lechones al destete.
