摘　　要：为研究不同能量水平饲粮对母貂生长性能、毛皮质量及血清脂类代谢相关指标的影响,试验选取60日龄88只体质量（0.76±0.03 kg）相近母貂,随机分成8组,分别饲喂代谢能为13.0,13.5,14.0,14.5,15.0,15.5,16.0,16.5 MJ/kg的试验饲粮。结果表明：（1）饲粮能量水平极显著影响母貂的体质量增长（P〈0.01）,当能量水平为13.0 MJ/kg时,母貂的末体质量显著低于其他各组（P〈0.05）；饲粮能量水平极显著影响母貂的干物质消化率、脂肪消化率、蛋白质消化率（P〈0.01）；（2）饲粮能量水平为14.0 MJ/kg时,母貂的毛皮质量显著高于其他各组（P〈0.05）；（3）血清中的总胆固醇含量随着饲粮能量水平的升高而升高,血清高密度脂蛋白、低密度脂蛋白随饲粮水平的升高呈现先升高后降低的趋势。由此得出：水貂在饲喂全价干粉料饲粮时,育成期（7～9月）母貂的饲粮代谢能为16.0 MJ/kg（总能为19.0 MJ/kg）能够得到较好的生长效果；冬毛生长期（10～12月）母貂的饲粮代谢能为14.5 MJ/kg（总能为22.5 MJ/kg）,母貂机体才能保持较好的状态,同时亦能得到较好的毛皮质量。The current study was performed to investigate the effects of dietary energy levels on growth performance,fur quality and serum biochemical parameters. Eighty-eight 60 d-age female minks were randomly divided into 8 groups. The dietary energy levels were 13. 0,13. 5,14. 0,14. 5, 15. 0,15. 5,16. 0 and 16. 5 MJ / kg,respectively. The results show that dietary energy levels extremely significantly influenced the body weight gain in female mink（ P 0. 01）,while the end body weight was the lowest in mink fed with 13. 0 MJ / kg dietary energy（ P 〈 0. 05）. Digestibility of dry matters,crude fat and crude protein was signicantly affected by the dietary energy（ P〈 0. 01）.The optimum fur quality of mink fed with 14. 0 MJ / kg dietary energy was better than the other group（ P 〈 0. 05）. Cholesterol concentration in serum gradually increased with the dietary energy enhanced,but the parameters of high density cholesterol and low density cholesterol had a peak at the15. 0 MJ / kg dietary energy,and then declined with dietary energy continuously increase. It could be summaried that the energy requirement of mink at growth period and pelting period was 16. 0 MJ / kg metabolism energy（ GE = 19. 0 MJ / kg）,14. 5 MJ / kg metabolism energy（ GE = 22. 5 MJ / kg）based on the datas of growth performance and fur quality,respectively.
