北貉南移后某些生理特性的研究

STUDY ON PHYSIOLOGCAL PARAMETERS OF RACOONDOGS AFTER KEEPING IN JIANGSU PROVINCE

对南移至江苏洪泽县的13只7月龄貉进行测定,体长为50.2±1.73cm,体重为6850±730.00g,胸围为40.8±4.93cm,体温39.11±0.58℃,呼吸49.92±4.89次/min,心率123.13±9.06次/min,红细胞(6.68±0.83)×10~6/mm^3,白细胞(13.06±2.28)×10~3/mm^3。试验结果表明,南移后的生理常数与东北北貉相似,但体重及体长明显大于南貉。南移后貉胃肠总重160.4g,占体重2.3％,其中胃重44.1g,占胃肠总重27.4％,小肠重91.3g,占胃肠总重56.9％,盲肠重5.6g,占胃肠总重3.5％。胃肠道具有肉食与草食的特征,属杂食兽动物。结果证明,南方不仅能养北貉,而且能养好北貉。

Northern racoon dogs originatcd in Wusuli River distrciet were immigratedto Hongze County, Jiangsu Province for years. Some physiological parameters of thirteenseven months old racoon dogs were measured. No differences of parameters were found be-tween the racoon dogs kept in North and middle china, such as body lengths (50.2±1.13cm), body weights (6850±730.00g), chest circles (40.8±4.93cm), body temperatures(39.11±0.58℃), respiratory rates(49.92±4.89/min), pulse rates (123.13±9.06/min),RBC(6.68±0.83×10~6/mm^3)WBC (13.06±2.28 ×10~3/mm^3). However the body weights ofnorthern racoon dogs are slightly heavier than that of immigrated subjects. The totalgastroenteric weights of immigrated racoon dogs are 160.4g (2.3% of body weight,in-cluding stomach 44.1g; small intestine 91 .3g. cccum 5.6g. The size of gastro-intestinal tractis similar to that of heterophagous animals. It is shown that northern racoon dogs can bekept in the area of Jiangsu Province.
