One hundred pigs were slaughtered sequentially to characterize and quantify protein deposition in two types (lean and obese) and sexes (boars and gilts) of Landrace pigs. The pigs were fed ad lib on a diet containing 18% protein, 1% lysine and 13,46 MJ DE/kg feed on an 'as is' basis from 6 weeks of age to a maximum livemass of 110 kg. Growth rate, feed intake, and rate of protein deposition followed a curvilinear pattern. Lean pigs had a higher rate of protein deposition than obese pigs, and boars a higher rate than gilts. Sex, type and Iivemass had no effect on the amino acid composition of porcine protein within the mass interval (30 -110 kg livemass) in the present study.
