Evaluación de diferentes niveles de Metionina orgánica en la alimentación de pollos broilers línea Cobb 500

Abstract

In the province of Chimborazo, Guano Canton, Rosario Parish, Sector San Miguel, owned by Mrs. Alicia Guerra Villa, it studied different levels of organic methionine (25, 50 and 75% of the 100% synthetic methionine) and a control treatmetwith the100% synthetic methionine under a Complete Randomized Design (CRD), the experimental results were submitted: analysis of variance (ANOVA), Tukey test for mean separation, even regression and correlation. Thus it was determined that in the initial phase (1-21 days), chickens subject to T2 (Balanced with 50% organic methionine plus 50% of synthetic methionine), obtained a live weight at 21 days of 930,75 g; weight gain of 892,63 g; FCR with 1,20, just as in the growth phase (21-35 days), reached a live weight of 2248,25 g; weight gain of 1317,50 g, feed conversion of 1,44, and the finishing phase (35 to 49 days), an end of 3682,25 g live weight was achieved; weight 2832,68 g, carcass yield with 76,93% and mortality of a bird. Additionally the highest rate of benefit / cost $ 1,19 that is a return of 19%. Therefore it is suggested 50% organic methionine plus 50% of synthetic methionine as it improves productive and economic parameters in the Cobb 500 chickens.
