Estudio del potencial productivo de pollos broilers COBB 500 en las diferentes regiones agroecológicas del Ecuador.

Abstract

This literature review investigated the productive traits of the Cobb 500 broiler line in different climatic zones of Ecuador, to determine the influence of environmental factors, advantages, disadvantages, and productive characteristics by sex. The information was obtained from scientific articles and theses in digital platforms such as Scielo, Scopus, DSpace, and Lantindex related to production parameters in poultry farming. Therefore, the results indicated averages for the Coast Region (Final weight=2579.08 g; Weight gain=2400.81 g; F.Co.= 4463.48 g; F.C=1.68 and % mortality 1.74), East Region (Final weight=3018.01 g; Weight gain=2976.74 g; F.Co.=5209 g; F. C= 1.63 and % mortality 0) for 42 days and Sierra Region (Final weight=2682.06 g; Weight gain=2717.21 g; F.Co. 5311.16 g; F.C= 1.94 and % mortality 6.67), for 49 days, the values differing between them since there is better productive performance in the Coast region. In the advantages, the Cobb 500 shows to be a genetically efficient line of fast growth, reaching higher weight with the least amount of feed and low feed conversion when using lower-cost diets than the Ross 308 because this line shows better results in the Sierra region, but with one week more of production. Regarding sex, the males show better productive characteristics than the females, obtaining a greater increase in weight and size due to competition for food. Therefore, it is concluded that the Cobb 500 broiler line has a higher production index in the Costa region, obtaining better productive characteristics than the Ross 308 line during the entire rearing cycle (49 days), gaining more weight in the shortest possible time, especially the males, which is fundamental in all poultry farms.
