Abstract: The levels of energy and protein in diet can directly affect the health and production performance of fur animals,also determine the feed cost and cause environmental pollution effect.The ratio of nutrient to energy in diet and its sources can affect the utilization of dietary energy,thus affect the effective energy value of diet.Therefore,exploring the optimum requirements and sources of energy and protein of fur animals possesses great significance in practical production.In this paper,the authors introduced the energy system of fur animals and summarized recent research progress on nutrient to energy ratio and nutrient sources,metabolism rules and requirements of energy and protein of fur animals,and forecasted the further researches direction,in order to offer worthy insights into precise feeding and diet preparation of fur animals.

Key words: fur animals; energy; protein; requirement
