This case report describes the diagnosis and surgical treatment of unilateral polydactylism of unknown origin in a calf. A six-week-old female German Holstein-Friesian calf was referred to the clinic with a hyperflexion of the fetlock and carpal joints of the right forelimb, associated with two surplus digits in the same leg, which was confirmed by radiographic examination. Surgery consisted of an osteotomy of the second metacarpal bone, a disarticulation in the antebrachiocarpal joint of the additional limb combined with an amputation of both odd digits. The follow-up of 12 months revealed a functionally sound heifer showing a good cosmetic outcome.

The aim of the present study was to investigate the effect of feeding frequency on body weight, carcass characteristics, and hormonal profile in Iranian Holstein calves. The study included 12 Holstein bull calves that were assigned to 2 groups according to initial live body weight. The animals were fed a TMR ration based on live body weight. The calves were fed a standard diet for 31 weeks; control calves were fed twice a day and treatment calves were fed 7 times a day. Live body weights were recorded every 21 days. Blood samples were collected 1 h after the final …
