桡神经切断术对鸟类飞翔能力影响的研究

研究了桡神经主干和分支切断术对家鸽和斑鸠飞翔能力的影响.试验结果表明,切断桡神经主干和切断桡神经分支(前翼膜背侧神经和前臂背侧皮神经总干)后,鸟类的精神状态和体型外貌均正常;桡神经主干切断术可限制鸟类飞翔,单侧桡神经切断术的限飞效果优于双侧.故认为在臂中部切断桡神经主干用于限制飞翔的手术是行之有效的,且单侧优于双侧;桡神经分支切断术可降低飞翔能力,但不能完全限制飞翔.桡神经主干切断术,手术简单、便于操作、效果良好,对于野生鸟类(特别是动物园内观赏的野生鸟类)的饲养具有一定的应用价值.

Influence of radial nerve amputation on the volitation of birds

This work studied the influence of radial nerve trunk and branch amputation on the volitation of pigeon and turtledove. The results show that, after cutting the radial nerve trunks front wing membrane and dorsal ganglia cutaneous nerve of forearm）, the birds＇ and branches （dorsal nerve of mental state and body appear- ance are normal. Radial nerve trunk neurotomy can restrict the volitation of bird, and the effect of unilateral neurotomy is better than unilateral neurotomy. It is believed that the unilateral neurotomy on the radial nerve trunk in the middle of wing is an effective way to restrict the bird volitation. However, radial nerve branch neurotomy can reduce the flying ability, but can not completely restrict volitation.
