Immunocastration (IM) is widely used in commercial pig production, particularly in male animals, but recent studies have evaluated
this technology in market gilts production up to heavier harvest weights (1). The IM in gilts results in growth performance improvement related to increased feed intake and body fat deposition (1,2). Thus, this work aimed at evaluating the effects of the feeding regimens
(restricted and ad libitum) and timings of the second immunization (V2) on fat quality and fatty acid profile of gilts harvest at 26 weeks of age.
