Considerations on the performance of immunocastrated male pigs

Animal, 2011
With the ongoing social pressure on surgical castration of pigs, an increase in the population of pigs that are either not castrated or immunocastrated (IC) can be expected.

Testicular morphometry as a tool to evaluate the efficiency of immunocastration in lambs

Animal Reproduction, 2022
This study aimed to evaluate the efficiency of immunocastration in lambs using testicular morphometry. Thirty lambs were randomly divided into two treatments (subcutaneous administration of 1.0 mL and 0.5 mL of an anti-GnRH vaccine) and a control group (1.0 mL saline solution).
