slugDifferent energy levels in the diet cause physiological changes in native goats of the Brazilian semi-arid
Journal Title: Journal of Animal Behaviour and Biometeorology - Year 2015, Vol 3, Issue 1
Abstract
The objective was evaluate the physiological parameters of native goats Canindé and Moxotó confined according to the diets containing two energy levels. 24 goats were used, males, with average weight of 15.22±1.76 kg, were randomly distributed in a completely casual design in a 2x2 factorial arrangement (two races and two diets). The experimental diets with higher energy level were evaluated: Diet A (2.7 Mcal of ME/kg DM), formulated with forage:concentrate 35:65; and one with lower energy level: Diet B (2,2Mcal of ME/kg DM) and forage:concentrate 70:30. Physiological parameters were measured on the rectal temperature (RT) and respiratory rate (RR) from 6:00 a.m. to 9:00 p.m. every three hours. The climate variables were taken throughout the experimental period. There were significant differences between breeds and diets for RR, with higher averages of this parameter to animals of the Canindé breed fed with diet of 2,7Mcal of ME/kg of DM. Environmental variables were elevated from12:00 p.m. and 3:00 p.m., however goats of Moxotó and Canindé breed maintained the RT within normal limits, but with na increase in RR. Animals fed the with diet of 2.7 Mcal of ME/kg DM had higher RR and showed up with a high degree of adapt ability to environmental conditions of the region
