Forty crossbred gilts (Hampshire, Belgium Landrace, Pietran) with initial average weight of 30.1±1.25 kg and high genetic potential for lean meat deposition were used to evaluate different lysine levels. A randomized block experimental design, with four treatments, five replications and two animal per experimental unit, was used. The treatments corresponded to the basal diet with 17.5% crude protein, supplemented with L-lysine-HCl, resulting in diets with 1.00, 1.10, 1.20 and 1.30% of lysine. The diets were supplemented with increasing levels of […]
