Abstract

In this study, data from an experimental broiler chicken population from Cobb-Vantress were obtained for analysis. A total of 1000 broilers were tested in a feed efficiency (FE) experiment. Genetic parameters of body weight (BW) and FE traits were estimated using genomic information. The heritability estimates of BW and FE traits for this line were found to be lower than those reported in other studies, which are estimated based on pedigree relations. The observed low estimates in this study might be due to pre-selection of the broilers for BW before the FE experiment, weak relationship between broilers in the data and use of only genomic information to enable estimation of genetic parameters since there was no available pedigree information for this population. Key words: Feed conversion ratio, body weight, broiler chicken, heritability, genomic information.
