Use of zinc-methionine and manganese-methionine in broilers diets: productive parameters and ascites syndrome incidence
In order to evaluate productive behavior, mortality rates and ascites syndrome susceptibility (AS) following addition of zinc-methionine (MZn) and manganese methionine (MMn), two experiments were carried out on 56 days old broilers. In the first, 2,400 sexed chicks were distributed in three treatments plus control in a randomized factorial 2 x 3 design. Factors assessed were gender, partial substitution of MZn (40 ppm) for inorganic zinc and MZn (40 ppm) + MMn (40 ppm). The second assay consisted of 2,100 mixed sex chicks distributed in three treatments: control, partial substitution of MZn (40 ppm) + MMn (40 ppm) for inorganic zinc an and manganese and MZn (20 ppm) + MMn (25 ppm). Results did not show significant (P>0.05) effects on body weight, feed intake and feed conversion. The joint addition of MMn + MZn decreased (P
