A total of 240 Hy-Line w36 Legho, from 55 to 65 weeks of age, were used. The experiment carried out in a completely randomized design, with four treatments, four replicates, each containing 15 hens. The experimental treatments included: 1. The control diet, consisted of sulphate source of Mn, Zn and Cu, 2. The diet consisted of Mn, Zn or Cu-Methionine chelate, 3. The diet consisted of Mn, Zn or Cu Hydroxy, and 4. The diet consisted of Mn, Zn and Cu Hydroxy, only 70% level relative to treatment 3. In the most of experimental weeks, the Mn, Zn and Cu hydroxy and chelate forms increased egg weight and improved significantly feed conversion ratio in the 62, 64 and 65 weeks of age, compared with the sulphate group of these elements (p /em>0.05).
