Efectos de la Fitasa Líquida Adicionada al Agua en Pollos con Dieta Comerciales

Abstract

In the Poultry Production Unit, Faculty of Animal Science, ESPOCH, we evaluated the effect of phytase added to the water settles in chicks fed two commercial diets, using 800 day-old chicks of age divided into 20 experimental units (each of 40 birds), and is distributed under a completely randomized design, using 4 treatments with 5 replications. In the initial stage (1-14 days old), the commercial diet fed phytase A more liquid, top answers were reached, weighing 421.40 g, feed conversion of 1,342 and cost / kg weight gain of $ 0.75 , between 14 and 28 days, with the commercial diet liquid phytase A more chickens reached higher weights (1.11 kg), better feed conversion (1456) and a cost of $ 0.76 / kg weight gain in the finishing stage , the best responses were achieved in the same way with the commercial diet phytase A more liquid, chickens presenting a final weight of 2.85 kg, the best feed conversion (1.88) and the cost of production ($ 0.91) in the overall evaluation, provides that the commercial diet provided more liquid phytase was obtained better weight gains (2.81 kg), feed conversion (1.716), and a production cost of $ 0.83 during the production stage. As recommended dietary phytase trade more liquid added to the drinking water as it has better production results.
