Abstract
El objetivo de la investigación fue determinar el efecto de la inclusión de infusión de hinojo (Foeniculum vulgare Mill.) al 2% en la dieta de marranas lactantes sobre sus parámetros productivos y de sus camadas al destete. Treinta y seis reproductoras Large White de la línea genética Topigs fueron distribuidas bajo un diseño completamente al azar en tres tratamientos: tratamiento sin infusión (T0), tratamiento con 250 mL de infusión (T1) y tratamiento con 500 mL de infusión (T2). Las características evaluadas fueron: incremento de peso de la camada, uniformidad de pesos de los lechones, porcentaje de morbilidad y mortalidad, consumo de alimento, intervalo destete-celo, reducción de su condición corporal y del perímetro torácico después del destete. Los resultados mostraron que el consumo de alimento de los lechones se redujo en T2, encontrándose diferencias significativas entre los tratamientos (P<0.05). Además, el T2 tuvo mejores valores para el incremento de peso de la camada, el porcentaje de mortalidad de lechones, la reducción de la condición corporal y del perímetro torácico. Sin embargo, no se presentó mejoras en la uniformidad de pesos de los lechones, el porcentaje de morbilidad y el intervalo destete- celo, no encontrándose diferencias significativas entre los tratamientos (P>0.05). El tratamiento T2 obtuvo la mejor relación beneficio-costo. Se concluye que la infusión de hinojo al 2% mejora no significativamente los parámetros productivos de las marranas y de sus camadas durante la lactación.
ABSTRACT The objective of the research was to determine the effect of including 2% fennel infusion (Foeniculum vulgare Mill.) in the diet of lactating sows on their productive parameters and their litters at weaning. Thirty-six Large White breeders of the Topigs genetic line were distributed under a completely randomized design in three treatments: treatment without infusion (T0), treatment with 250 mL of infusion (T1) and treatment with 500 mL of infusion (T2). The characteristics evaluated were litter weight increase, piglet weight uniformity, percentage of morbidity and mortality, feed consumption, weaning-heat interval, reduction in body condition and chest circumference after weaning. The results showed that the feed consumption of the piglets was reduced in T2, with significant differences being found between the treatments (P<0.05). In addition, T2 had better values for the increase in litter weight, the percentage of piglet mortality, the reduction in body condition and chest perimeter. However, there were no improvements in the uniformity of piglet weights, the percentage of morbidity and the weaning interval, and no significant differences were found between treatments (P>0.05). Treatment T2 had the best benefit-cost ratio. It is concluded that 2% fennel infusion does not significantly improve the productive parameters of sows and their litters during lactation.
