Valoración de dos compuestos enzimáticos usados en el alimento balanceado para pollos broiler sobre los parámetros productivos.

Abstract

The present research was carried out at the facilities of the Technical University of Machala, province of El Oro, in a shed of the "Santa Inés" farm located in the Faculty of Agricultural Sciences, following the procedure established in the Guide of Good Poultry Practices (GPP). The objective of the essay was to evaluate two enzymatic compounds applied in a chicken smash feed formula for broiler chickens, analyzing the effects and their possible benefits in the productive parameters after the ingestion of feed with the enzymatic compounds. The work carried out was of the experimental type, where 3 treatments were used with 4 repetitions respectively, in each experimental unit 15 broilers were placed; in this way a Completely Randomized Design (CRD) was used using a total of 180 broilers of the Cobb 500 breed. The first treatment (T1) corresponded to the feed that included the enzymatic compound Huvezym PC®, in the second treatment (T2) the enzymatic compound Rovabio® MAX ADVANCE was incorporated; finally, the third treatment (T3) did not include enzymes, determined as a control treatment; it should be noted that the name used for each treatment, that is, T1, T2 and T3 were randomly distributed for each treatment. Data were collected daily, such as water consumption, feed administration, management control to provide quality of life and weekly, the accumulated feed consumption, weight obtained and the elaboration of the balance corresponding to each treatment according to the stage of life in which they were. The variables studied were: Average live weight, feed consumption, water consumption, conversion index, mortality, PEF (production efficiency factor), weight per m2 (Kg), average expenses per EU, cost per Kg of standing meat per m2, cost of standing meat per Kg, cost of standing meat per Kg, cost of standing meat per Lb. Once the treatments of each experimental unit were established, they were labeled based on the replicate and its treatment; the statistical evaluation was carried out using Statgraphics Centurión XV.I.® software, applying a single factor analysis (ANOVA), using the Tukey hsd confidence interval (95%). The results of the inclusion of enzymatic compounds in the balanced formula for broiler chickens have no effect on the variables analyzed and on the productive parameters of the broilers studied (average live weight, feed consumption, water consumption, conversion rate, productive efficiency factor, mortality, average weight per m2); on the other hand, the economic parameters (expenses per experimental unit, cost per kg of standing meat per m2, cost of standing meat per kg and cost of standing meat per lb) were not significantly affected, which indicates that the inclusion of these enzymatic compounds in the broiler chickens' feed is neither detrimental nor beneficial for poultry production.
