Administração de leite de coco e leite de coco com glutamina em leitões recém-nascidos de duas linhagens comerciais

Abstract

The higher mortality rate in pig farming focuses on the first three days after birth, pincipalmente in piglets weighing less than a kilogram, which causes a reduction in profits in the sector. The objective of this study was to evaluate weight gain and mortality rate of piglets from birth to weaning when supplemented with coconut milk or coconut milk and glutamine. 448 piglets Breeds Dan -bred and Naima were followed. The experiment was conducted at GRIMPISA commercial farm, located in the city of Uberlândia, October 2013 to November 2013. Two hours after ingestion of colostrum , was administered the first dose of treatment and the amount of coconut milk used was 20 ml per animal containing 2g glutamine in piglets weighing up to one pound and six hundred . The effect on growth was observed, implying the possibility of weight gain and decreased mortality of piglets. The experiment was conducted in a completely randomized design in a factorial arrangement consisting of two lines and 3 treatments. When comparing the means the Tukey test for the cases of analysis of variance and mean comparison tests put to the cases in which we used the Kruskal - Wallis test was used. We used the test to compare proportions (binomial test) to check for significant difference between the proportion of diarrhea or deaths within each line or each treatment. These tests also adopted the 5% significance. Still proceeded to an analysis of the Spearman correlation between the variables birth weight, diarrhea and death. There was no difference (P > 0.05) between treatments for weight gain from birth to weaning. Supplementation of coconut milk or coconut milk supplemented with glutamine had no effect on weight gain and mortality of piglets in this study.
