Researchers from Saskatchewan provide strong evidence against using elastic band or surgical castration of mature bulls based on pain response, time to heal and post-castration weight loss. Intact animals could be marketed one to two months earlier than castrates, which saves feed. Owners with guaranteed buyers willing to purchase green calves horns and testicles in place , at the same price as processed calves castrated and dehorned , might be advised to avoid these procedures. The need for repeated injections likely would discourage its adoption. In general, there are no differences in liveweight gains for bulls and steers in the 21 days following castration at one month of age. Although there is no evidence that pain differs between young and older calves, there is less risk with castration of young calves. Vaccines must be given weeks in advance of banding.

The differences in liveweight gain of castrates and bulls are first apparent at four to five months.

The Burdizzo Figure 3 must be in good condition. Which is selected will depend on the available handling facilities, the producer's ability, the awareness of castration effects and the market available for the calves. Although there is no evidence that pain differs between young and older calves, there is less risk with castration of young calves. The jaws must be parallel and close uniformly across their width so pressure will be evenly distributed across their length. Physical methods are most common. Print Share Castration of Calves.
