ABSTRACT
One of the most regulating and controlling of energy homeostasis is Melanocortin-3 receptor (MC3R) and for this locus have been reported some operative polymorphism. The aim of the study was to investigate polymorphism of the MC3R gene in Fars indigenous chicken and define its association with growth and reproductive traits. From 200 chicken of Fars (province located in the south of Iran) indigenous station, DNA was extracted and was determine their genotypes using PCR-RFLP technique. Generalized linear model was used to calculate association between genotypes and reproductive traits. Results showed that genotype AA, in comparison with the GG genotype positively affect average egg weight at ages 28 (EW28), 30 (EW30) and 32 (EW32) weeks (P< 0.05), as well as, genotype AG in comparison with the GG genotype, positively affect average egg weight at age 30 (EW30) weeks (P< 0.05). Moreover, the breeding values for AG genotype in comparison with GG genotype, showed better result for egg weight mean at age 32 (EW32) weeks and egg weight mean at ages 28 (EW28), 30 (EW30) and 32 (EW32) weeks (P< 0.05). Consequently, MC3R gene can be considered as a candidate marker in poultry breeding. Regarding to these results, it makes a foundation for further association investigations between MC3R polymorphism and the other economic traits in chicken.
