Estratégias do fornecimento da glicerina bruta para cabritos no pré-abate

Abstract

The objective of this study was to evaluate the physiological parameters, carcass and meat characteristics of goats fed with crude glycerin during pre-slaughter rest. 28 male goats were used, with initial mean body weight of 14,63±3,8 kg. The animals were distributed in the treatments: Treatment 1: animals did not receive crude glycerin (GLY); Treatment 2 (GLYGLY): animals received 10 g 100 g-1 of GLY in the confinement diet. At pre-slaughter, each goat had available 168 g of GLY and water; Treatment 3 (GLYW): animals received 10 g 100 g-1 de GLY in the confinement diet; Treatment 4 (WGLY): animals did not receive GLY in the confinement. At pre-slaughter, each animal had available 168 g of GLY and water. Animals GLYGLY and WGLY spent more time ingesting water. Higher concentrations of albumin were observed in the control treatment. Animals GLYGLY presented lower concentrations of cortisol and urea. The GLY improves the degree of hydration of goats, reduces concentrations of stress indicators and does not alter the carcass characteristics, quality and concentrations of heavy metals in the meat.
