Two experiments were carried out to evaluate the use of two methionine sources (powder or liquid) in diets based on total and digestible amino acids for white and brown growing pullets at starter phase (1 to 6 weeks old) and grower phase (11 to 16 weeks old). In each experiment, 384 birds were distributed to a completely randomized design in a 2 × 2 × 2 factorial arrangement, composed of bird strain (Hy-Line W36 and Hy-Line Brown), source of methionine […]
