本试验旨在研究不同锌源与水平对冬毛期母貂体重、养分消化率及氮代谢的影响。选择84只母貂作为试验动物，随机分为7组，每组12只，日粮中分别添加蛋氨酸螯合锌0mg/kg （A组）、15mg/kg （B组）、30mg/kg （C组）、45mg/kg （D组）、60mg/kg （E组）、75mg/kg （F组）和硫酸锌60mg/kg （G组）。结果表明，E组与G组母貂的体重、养分消化率和氮平衡没有显著差异（ P＞0.05），但B组脂肪消化率显著高于G组；E组母貂的体重（160d）和平均日增重最高，显著高于D组（ P＜0.05）；D组母貂蛋白质消化率最高，与C组差异显著（ P＜0.05）；B组母貂脂肪消化率显著地高于其他各水平组（ P＜0.05）。由此得出：冬毛期母貂日粮中添加蛋氨酸锌能促进水貂体重增加和养分利用。

This study was conducted to evaluate the effects of different sources and levels of zinc on body weight ,nutrient digestibility and nitro-gen balance of female mink in furring period .Eighty four female minks were randomly allocated into 7 groups ,each with 12 replicates .The diets were supplemented with zinc methionine at levels of 0mg/kg(group A) ,15mg/kg(group B) ,30mg/kg(group C) ,45mg/kg(group D) ,60mg/kg (group E) ,75mg/kg(group F) and with Zinc sulfate at the level of 60mg/kg(group G) ,respectively .The results showed that ,there were no significant difference between group E and group G on body weight ,nutrient digestibility and nitrogen balance of female mink ( P>0.05 ) ,but fat digestibility was significantly higher than that of group G .Body weight(160d) and average daily gain of group E were the highest ,significant-ly higher than that of group D ( P<0.05 ) .Protein digestibility of group D was the highest ,markedly higher than that of group C ( P<0.05 ) .Fat digestibility of group B was evidently higher ( P<0.05 ) than those of other groups having different Zinc levels ( P<0.05 ) .In conclusion ,body weight and digestibility could be improved by using zinc methionine in diet for female minks in furring period .
