Investigations on flight restraint in partridges

Contemporary techniques commonly used to deflight birds have one or more disadvantages. The results can be temporary, result in physiologic and esthetic malformations, or limit the basic needs and reproduction functions to accomadate daily life.This study aimed comparatively at revealing the degree of deflight effects of the tenectomies of the radial and ulnar extensor carpi muscles at their insertios both extensing the carpal joint and capsulectomy of the cubiti joint possessing strong extention-flexion movements in chukars (Alectoris chukar) either seperately or in combination on flight limitation.A number of 30 mature chukars having no appearent flight faults, regardles of sex, were equally divided into three groups. The first group was applied unilateral tenectomy of the radial and ulnar carpal extensor muscles at their insertios.The second group underwent unilateral capsulectomy of the cubiti joint. Both the unilateral tenectomy and capsulectomy were applied to the third group. Fligth control was done in all the birds from all the groups on the 28th day after the surgery. These controls were done 5 times with 15 days of interwals to evaluate timely effects of the healing on flight.Consequently, locomotor performans tests done showed that both techniques limited the flight in chukars without any physiological defects. These tests also revealed that capsulectomy technique was more succesful in flight limitation than tenectomy technique.
