Effect of amino acid level in the pig diet during growing and early finishing on growth response during the late finishing phase of lean meat type gilts

This experiment examined the influence of different amino acid levels during the growing and early finishing diet and the late finishing diet on growth performance and carcass quality of a lean meat type gilt. In a two by two factorial trial, 96 gilts were divided over four treatments. The two factors were (1) amino acid level in growing and early finishing and (2) amino acid level in late finishing. For the low amino acid diets we lowered the lysine, methionine, threonine and tryptophan levels by 20% and 30% in the growing and two finishing phases, respectively.
