Research Progress of Respiratory Quotient in Animal Respiratory Calorimetry
Respiration quotient is an essential index in the process of animal respiration calorimetry,which can not only test the accuracy of respiration calorimetry device,but also verify the oxidation of nutrients in animal body.However,due to the detection equipment,diet type,animal species and environmental factors will have a certain impact on the respiratory quotient,affecting the accuracy of animal respiratory calorimetry.Therefore,this paper mainly introduces the definition,significance and calculation method of respiratory quotient,and ex-pounds the influence of animals,environment,respiratory chamber and diets on respiratory quotient.At the same time,it summarizes the application of respiratory quotient in animal production,in order to provide a bet-ter reference for the application of respiratory quotient in the process of animal respiratory calorimetry.[Chinese Journal of Animal Nutrition,2024,36(5):2872-2885]
