ResumenThe effect of lysine supplementation in diets for growing pigs on weight gain, carcass and meat characteristics was evaluated. Eighteen castrated pigs (Yorkshire, Hampshire, Duroc y Landrace) of 10.13 kg initial weight and 40 d of T2 = T1 + 0.285 kg of lysine / 100 kg of feed; and T3 = T1 + 0.569100 kg of feed. Basal diet contained 20.81\% CP and 3,460 Mcal/kg of ME. Pigs were fed for 33 d. At the end of the feeding trial final weight, cross height (cm) and thoracic circumference (cm), and subcutaneous fat measured with ultrasound were recorded. For carcass and meat characteristics, four pigs per treatment selected at random were slaughtered. Samples of rib, ham and shoulder from each carcass were analyzed for DM, CP, fat and ash. There were no differences (P>0.05) between treatments for weight gain, cross height, thoracic circumference, weight at sacrifice, hot and cold carcass yields, rib eye area and subcutaneous fat. The content of DM, CP, fat and ash was similar (P>0.05) among treatments. It is concluded that lysine as growth promotant of lean tissue was no reflected in weight gain, carcass characteristics or meat composition of the growing pigs.es_ES
