貉生长受阻主要原因初探

Causes of Growth Retardation in Raccoon Dog

对某2个养殖场出现的30只生长受阻的貉采用全价颗粒饲料处理,每10 d称重1次,观察其生长情况,并对通过饲喂全价料未能恢复生长的貉取样进行解剖和细菌学检查,确定病因和治疗方案。第一批20只僵貉中有15只通过饲喂全价颗粒料恢复生长,对剩余5只貉中的3只进行解剖发现均感染巴氏杆菌,对另外2只用氟苯尼考治疗,继续饲喂全价颗粒饲料后均恢复生长。第二批10只僵貉在采食全价颗粒饲料后,均恢复生长。由此可见,饲料营养不平衡或不全价是僵貉形成的主要原因,全价饲料喂养可使其恢复生长;其次是巴氏杆菌感染,适当治疗可恢复生长。

Thirty raccoon dogs with growth retardation from two farms were fed a balanced pellet feed.The animals were weighed every 10 d to monitor the weight gain.Animals ceased growth and even loss weight were dissected and bacterial test was conducted for diagnosis and treatments.Twenty animals were from one farm,of which 15 grew well after fed pellet feed.of the 5 animals which did not grow,3 were dissected and confirmed to be infected by Pasteurella.The rest 2 animals were treated with florfenicol and re-grew.All the 10 animals from the other farm grew well when fed balanced pellet feed.It is suggested that nutritional inadequacy or unbalance is the main reason for growth retardation of raccoon dog,followed by infection of Pasteurella.
