PRODUCTIVE AND REPRODUCTIVE BEHAVIOR OF FEEDED SOWS WITH REPRODUCTIVE FEED SUPPLEMENTED WITH COCONUT OIL | COMPORTAMIENTO PRODUCTIVO Y REPRODUCTIVO DE CERDAS ALIMENTADAS CON PIENSO REPRODUCTOR SUPLEMENTADO CON ACEITE DE COCO

Spanish; Castilian. Se utilizaron 90 reproductoras YorkLand, con paridades 2, 3 y 4, las cuales fueron distribuidas en un diseo completamente aleatorizado en dos tratamientos de 45 cerdas cada uno: un tratamiento control sin la adicin del aceite de coco y un tratamiento experimental con la inclusin del 1,5% de aceite de coco en la dieta de las cerdas lactantes. El estudio tuvo una duracin de 26 das. Se midieron las variables prdida de peso y das de vaco en las reproductoras. En las cras se midi el peso al nacer, a los 15, 21 das y al destete. Se determin la ganancia media diaria de las cras y se registr las muertes y los procesos entricos en ambos tratamientos Hubo diferencia altamente significativa a favor del tratamiento con aceite de coco para la prdida de peso y reduccin de los das de vaco en reproductoras para p˂0.0001. Las cras tuvieron un aumento de peso considerable en cada uno de los pesajes, la ganancia media diaria fue superior en la descendencia de las cerdas suplementadas para una p˂0.0001, tambin hubo una mejora en los indicadores de salud reducindose la presentacin de casos diarreicos. Se concluy que con la utilizacin del 1,5% de aceite de coco como suplemento en la alimentacin de las cerdas lactantes se favorecieron los indicadores reproductivos estudiados y hubo una mejora en la prdida de peso. Por otra parte las cras tuvieron un comportamiento superior en relacin al peso y a la ganancia media diaria.

English. 90 YorkLand breeders were used, with parities 2, 3 and 4, which were distributed in a completely randomized design in two treatments of 45 sows each: a control treatment without the addition of coconut oil and an experimental treatment with the inclusion of 1.5% coconut oil in the diet of lactating sows. The study lasted 26 days. The variables weight loss and days of emptiness in the breeders were measured. In the offspring the weight at birth, at 15, 21 days and at weaning was measured. The average daily gain of the offspring was determined and deaths and enteric processes were recorded in both treatments. There was a highly significant difference in favor of coconut oil treatment for weight loss and reduction of days of emptying in breeders for p˂0.0001. The offspring had a considerable weight gain in each of the weighings, the average daily gain was higher in the offspring of the supplemented sows for a p˂0.0001, and there was also an improvement in the health indicators, reducing the presentation of diarrheal cases It was concluded that with the use of 1.5% coconut oil as a supplement in the feeding of lactating sows, the reproductive indicators studied were favored and there was an improvement in weight loss. On the other hand, the offspring had a superior behavior in relation to weight and average daily gain.
