摘要
日粮能量和蛋白质水平可直接影响毛皮动物的健康状况与生产性能,决定日粮成本,产生环境污染效应。日粮中营养物质的能量比和来源会影响动物对日粮能量的利用率,从而影响日粮的有效能值。因此,探究毛皮动物能量与蛋白质需要量,明确日粮中营养物质的能量比和来源对实际生产具有重要意义。作者介绍了毛皮动物能量体系,综述了国内外毛皮动物日粮营养物质能量比和来源、能量与蛋白质需要量及其代谢规律研究进展,并对未来研究发展方向进行展望,旨在为毛皮动物精准化饲养及日粮配制提供参考。
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.
