Evaluación de alimento balanceado en lechones en la etapa pre-destete.

Abstract

Pig production has become a valid alternative for the Sebastian farm in economic terms. However, it was evidenced that the productive problem is expressed in the low weight yields of piglets in the stage to pre-weaning. For this reason, the objective of this study was to evaluate balanced feed in piglets in the preweaning stage, to determine productive responses in accordance with their physiological stage. For this experimental study, a randomized complete block design (RCBD) was used. For this purpose, 80 piglets were randomly assigned; 20 animals were assigned to each of the 4 treatments: control, Treatment 1 (T1), Treatment 2 (T2) and Treatment 3 (T3). The Control group only received mother's milk from the sow, while the experimental groups T1, T2, T3 were given pellet concentrate feed from 7 days of age. The results showed statistical trends in voluntary feed intake. Treatment 2 was superior compared to treatment 1 and treatment 3, which were also similar. With respect to live weight, no significant differences were detected between treatments, although the treatment by period interaction tended to show slight differences. Despite these slight differences, feed conversion did not differ between treatments. Finally, in economic terms, treatment 1 showed a range of 11 to 19 percent savings versus treatment 1 and treatment 3, respectively. In context, it was concluded that there were slight productive and cost-benefit differences when comparing different supplements for pre-weaning piglets.
