Abstract
An indirect calorimetry system for rapid determination of CO2 and CH4 production and O2 consumption to estimate heat production of animals was built at Escola de Veterinária da Universidade Federal de Minas Gerais, Brazil. Procedures for determination of correction and calibration factors for gas analyzers and the whole system, using standard test gases were described. In addition, a metabolic trial was performed to evaluate heat production of lambs fed ad libitum. It is concluded that the system is suitable for heat production determinations in small and medium size animals.
Um sistema de calorimetria para a determinação rápida da produção de CO2 e CH4 e do consumo de O2 de animais para o cálculo da produção de calor foi construído na Escola de Veterinária da Universidade Federal de Minas Gerais. Foram descritos os procedimentos para a determinação dos fatores de correção dos analisadores e calibração do sistema utilizando-se gases padrão. Adicionalmente, um ensaio de metabolismo foi realizado para se avaliar a produção de calor de ovinos alimentados ad libitum. Conclui-se que o sistema está apto para determinações de produção de calor em animais de pequeno e médio porte.
