Effect of immunocastration using Improvac on the regulation of adiponectin and leptin in the testes of Landrace boars [PDF]

open access: yesMedycyna Weterynaryjna, 2022
Immunological castration of male pigs is an attractive alternative to surgical castration used in many countries to reduce the production of the main androgen, androstenone, and skatole, responsible for meat taint. To understand the effect of gonadoliberin (GnRH) vaccination with Improvac on the functional status of Landrace pig testes at the molecular
