Efectos de la inclusión de microorganismos eficientes (ME) en la dieta de pollos de engorde de la línea Ross – sobre los parámetros productivos.

Abstract

The objective of this research was to evaluate the effect of the inclusion of commercially grown Efficient Microorganisms (EM) (Lactobacillus, photosynthesis and yeast) in the diet of broiler chickens on their productive performance and cost-benefit ratio. The research was carried out in the Cínera village, in the municipality of Arboledas - Norte de Santander. A total of 18 birds were divided into three treatments under a randomized design, control treatment, treatment 1 (5.0cm3 ME) and treatment 2 (10cm3 ME), each with six experimental units. The parameters of final body weight (BW), weight gain (WG), feed conversion (FC), feed efficiency (FE), carcass weight (CW), carcass yield (CW), European efficiency factor (EPEF) and productivity index (PI) were evaluated, as well as the cost of supplementation, net income per broiler (INPP) and net income per broiler carcass (INPC) within the economic aspect. The data obtained were analyzed using ANOVA statistical tests with a significance of 5%, with initial weight as a covariate. As results, similar behavior was obtained in all the productive parameters evaluated (p ≥ 0.05). In the economic analysis, the control treatment presented the best values for feed cost per kilogram of meat produced, INPP and INPC. It is concluded that the use of ME in broilers allows obtaining similar results in terms of broiler production performance, but increases production costs and decreases the profitability margin with respect to conventional feeding with commercial balanced feed.
