Análisis de polimorfismo de nucleótido simple en el gen FASN y su relación con características de producción en pollos

Abstract

The purpose of this work is to evaluate possible associations between a Single Nucleotide Polymorphism(SNP) of FASN gene and each of the following productive traits: Feed Intake (FI), Weight Gain (WG) and FinalBody Weight (FBW). At the National Institute of Agricultural Technology (INTA), 229 chickens were organizedand bred in full sib and paternal half sib families, these birds were caged individually with water and fed withpellet ad libitum. Body weight was recorded at 54 days old and then individual feed intake and weight were determined weekly during 21 days. FASN gene genotypes were identified by PCR amplification and digested by endonuclease Hae III. Phenotypical data were analyzed independently by ANOVA with a random Model.The SNP evaluated in this work has not been demonstrated as affecting the considered traits.
