摘要 [目的]探讨幼獐活体取乳的最佳日龄。[方法]2014年6~7月,在杭州富阳市养獐场开展幼獐活体取乳试验研究。[结果] 随着幼獐日龄的增加,取乳量也随之增加,但相邻日龄之间差异不显著,相隔2 d以上的幼獐取乳量存在显著差异。幼獐术后存活率呈现“两头低中间高”的特征。[结论]幼獐的最佳取乳时期是18~19日龄,而最佳取乳量为133~146 g。

Abstract [Objective] The research aimed to explore the optimum day age of taking milk of young roe deer in vivo.[Method] The experiment of taking milk of young roe deer was carried out in the roe deer farm in Fuyang City of Hangzhou from June to July of 2014.[Result] The milk-taking amount of young roe deer was increased with the day age.There was no significant difference of milk-taking amount between adjacent day ages,but there was significant difference of milk-taking amount between at least interval 2 day ages.The postoperative survival rate of young roe deer showed the trend of “low,high,low”.[Conclusion] The optimum day age of taking milk of young roe deer was 18-19 day-old,and the best milk-taking amount was 133-146 g.

獐(Hydropotes inermis)隶属哺乳动物、偶蹄目、鹿科、獐属,又称河麂、牙獐等,是国家二级保护动物。在IUCN红色物种名录中,獐被列为低危或近危种[1]。獐在我国曾广泛分布于辽东半岛、华北平原及长江两岸,包括上海江苏、浙江、安徽、湖北、湖南等省市,后来,由于栖息地的大量丧失和人类开发利用活动的不断加强,獐种群无论数量还是分布均急剧退化[2-5]。为了满足獐资源的需求,人们开始对獐的人工养殖。
人们利用獐最主要的是“獐乳”,为幼獐吮吸母乳后在胃中凝聚的乳白色奶块,俗称獐宝。獐乳主要用于治疗小儿疳积等消化不良症,具有显著的疗效[3]。临床研究发现,獐乳具有调节脾胃、促进儿童发育的功能[6]。为了获取较多的獐乳,幼獐活体取乳技术在不断地进行试验研究,其基本方法就是从幼獐胃中取出“獐乳”,然后经术后护理,使其能够继续成活,正常生长、繁衍后代,但该技术仍不够成熟。笔者在杭州富阳市养獐场开展了幼獐活体取乳试验。
