Evaluación productiva de pollos de engorde utilizando lecitina como emulsificante

Abstract

In the Poultry research program carried out in the animal science faculty of ESPOCH, located in Riobamba km 11/2 Panamericana Sur, Chimborazo province, the productive broiler chicken evaluation by using lecithin as emulsifier, 300 (T1). 400 (T2) y 500 (T3) mg / kg was carried out; this was compared with a (TO) control treatment, and put under a (DCA) completely ramdomizeddesing. The experimental result were put under a significance tests and (ADEVA) variance analysis for the average difference, Duncan Test was used for the average separation at PS 0,05 and P S 0,01. In this way, results with highly significant statistical differences (P <0,01), were gotten by using 500 mg of lecithin as meal. In the initial stage (1-21 days), the following increases were reported: Total weights 730.03 g, weight gaining 682.28 g, food conversion 1,14. In the growing stage (22-35 days), there were increases in: Total weights 1692.69 g, weight Gaining 962,66 g, 1,4 4, food Conversion 1,44. In the broiler stage (36-49 days), the were increases in: Total weights 2802,67 g, weight gaining 1109,89 g, food conversion 1,96, european efficiency index (353,11), with a reduction in the mortality. In the carcass yield 84,25% was reported and 35,33% in breast meat yield. According to the economic analysis, it was determined that using 500 mg of lecithin per kilogram in food a higher profit is obtained, this shows a cost benefit of 1,24 dollars, higher than 0,05 dollars regarding to the group control.
