Sows’ parity and coconut oil postnatal supplement on piglets performance

ABSTRACT

Objectives. The study aimed to evaluate the effect of sows’ of different parities and the supplement of coconut oil for piglets, on the development of litter. Materials and methods. A total of 51 sows of different parities and their 642 piglets were used in the trial. Each piglet was weighed and identified at birth in a sequential order. They were randomly distributed in two treatments (CG=control group and TG=test group). TG piglets had the first access to a dosage of 3.0 ml of coconut oil 12 hours after birth, and the second at 36 h after the first. Piglets were weighed at 21 days. In order to analyze the effect of the coconut oil supplement as a function of the weight at birth, piglets were grouped according to their weight (0.600 to 0.900 kg; 1.000 to 1.499kg; 1.500 to 1.999 kg; and 2.000 to 2.499 kg). Results. Sows parity affected the number and weight of born piglets. Sows in 4th, 5th and 7th parity had a larger litter than those from the 2nd parity. Sows from 2nd and 3rd parity had a lower number of piglets but heavier litter. No effect of the coconut oil supplement on neonatal piglets’ performance was found. Conclusions. The coconut meal was neither beneficial to neonatal piglets nor to those with low weight at birth, which usually present low body energy.

RESUMEN

Objetivo. El objetivo del estudio fue evaluar el efecto del número de partos y el suplemento de aceite de coco en lechones recien nacidos. Materiales y métodos. Se utilizaron 51 cerdas de diferentes partos y sus 642 lechones. Cada lechón se pesó y se identificó al nacer en orden secuencial. Fueron distribuidos aleatoriamente en dos grupos (CG = control y TG=tratamiento). Lechones TG tenían el primer acceso a una dosis de 3.0 ml de aceite de coco 12 horas después del nacimiento, y el segunda a las 36 h después de la primera. Los lechones fueron pesados a los 21 días. Con el fin de analizar el efecto de los suplementos de aceite de coco con relación al peso al nacer. Los lechones fueron agrupados de acuerdo con su peso (0.600 a 0.900 kg; 1.000 a 1.499 kg; 1.500 a 1.999 kg y 2.000 a 2.499 kg). Resultados. El número de partos afectó el peso y el número de lechones nacidos. Cerdas en cuarto, quinto y séptimo parto, tuvieron una camada mayor que las de segundo parto. Las cerdasde segundo y tercer parto tuvieron menor número de lechones y con peso mayor. No se encontró efectodel suplemento de aceite de coco en el desarrollo de los lechones recién nacidos. Conclusiones. Loaceite de coco no es favorable para los lechones recién nacidos, tampoco para aquellos con el bajopeso al nacer, que normalmente presentan la energía corporal baja.
