One experiment was carried out to determine the lysine (Lys) and metabolyzable energy (ME) levels for breeding gilts. One hundred and eight Seghers® gilts (Large-White x Landrace/Large-White) were alloted to a complete randomized design with a 3×3 factorial design, three levels of Lys (0.55, 0.75 and 0.95%) and three levels of ME (3,100, 3,250, and 3,400 kcal ME/kg). The treatments were the same from the beginning of trial (housing) to the slaughter (30 days of gestation). There was only effect […]
