Eficiencia de los promotores de crecimiento en pollos Broiler.

Abstract

The objective of this research project was to determine the efficiency of some growth promoters in broiler chickens, considering parameters such as weight gain, feed conversion, fattening days, in addition to product quality in terms of food safety and security. Considering a descriptive review of research published on the website (internet), indexed journals in recognized databases, doctoral theses and scientific articles in Scielo, Redalyc, cdnsciencepub, virtual libraries such as Repository of the Catholic University of Santiago de Guayaquil, Repository of the State University of the South de Manabí, DSpace of the Escuela Superior Politécnica del Litoral, and DSpace of the Escuela Superior Politécnica de Chimborazo a comparison of the investigative works on order to evaluate the different growth promoters in the breeding and exploitation of broiler chicken was carried out. According to the results obtained, an average initial weight of 40.23 g was evidenced, and the best growth promoter numerically was the use of microbial culture with a final weight of 498.77 g. Within these growth promoters the less effective was the use of butanoic acid which reported a final weight of 372.59 g at 15 days. Regarding the growth stage of broiler chickens, 4 investigations reviewed determined the efficiency of the promoters of growth. The prevalence continues with the addition of the microbial culture with great efficiency in the productive parameters, final weight 1600.83 g, weight gain of 1500.83 g, feed conversion of 1.43 points. It was concluded that the use of growth promoters (Microbial culture); produced excellent results in the production of broiler chickens, therefore its application is recommended in diets in the initial phase, growth and fattening.
