Utilización de Fitasa Microbiana ( Allzyme S. D. Phytase) en la Cría y Engorde de Pollos

Abstract

The investigation was carried out in Experimental Academia Farm and Production Zootechnic Enginery School ESPOCH, Which was used 200, 400 and 600 fitasa g/Im with a treatment controlled two serial rehearsals, the same one was analyzed totally at random by means of to design analying the rehearsals simultaneously; picked up information like:Weight, earnings of weight, consumption food, nutritious conversion, cost for Kg of weight, mortally in the stages growth, put on weight and total stage, besides was also analyzed the relation benefit cost. As a result abaut present research one had the best earnings of weight with different levels of fitasa 200, 400, and 600 g/Tm the values were 1.13, 1.12, and 1.13 Kg in the stage of growth, although in the stage on weight and total stage, the earnings of weight were equaled, finally in which didn`t differ significantly, it can show that the nutritious conversion was between 2.01 couple the level 200 g/Tm about food at 2.087 for the level 600g/Tm, in which significant differences don`t exist, and concludes that the fitasa use in the chicken diets didn`t include in the productive parameters, finally is recommended to replay the investigation
