Abstract

Two experiments were carried out with weaned piglets from 8 to 25 kg live weight in order to determine the dietary amino acid content necessary for maximum growth. Six diets based on wheat, soya-bean meal, soya-bean oil and free amino acids were compared in each experiment. Essential amino acids were in the same relative proportion for all diets: (methionine + cystine)/lysine = 0·60 to 0·65; threonine/lysine = 0·65; tryptophan/lysine = 0·19. The range of amino acid content was 9·53 to 12·52 g lysine per kg in the first experiment and 11·34 to 15·94 g lysine per kg in the second experiment. The number of piglets used per diet was 136 (20 pens) and 106 (16 pens) in respectively the first and the second experiment. The relationship between either dietary lysine content or daily lysine intake and growth rate was quadratic and significant. Dietary lysine content and daily lysine intake which enable maximum growth were calculated according to this model. Dietary lysine contents were 15·5 and 14·9 g/kg for the first 3 weeks (8 to 17 kg) and for the overall post-weaning period (8 to 25 kg) respectively. Daily lysine intakes were 10·6 and 13·3 g/day respectively for the same two periods. Reasons for these values being higher than those currently cited are discussed.
