: In the present study, the effect of immunocastration on carcass traits, meat quality, reproductive
organs development, and boar taint compounds was investigated. Male piglets (50% Duroc crosses) were
randomly assigned to three treatment groups: entire males (EM; n = 19), surgical castrates (SC; n = 20) and
immunocastrates (IC, vaccinated with Improvac® at the age of 79 and 142 days; n = 21). Pigs were fed ad
libitum and weighed at the time of first and second vaccination and before slaughter (176 days of age).
