Detection of genetic marker associated with egg production traits in Pradu Hang Dam and Chee chickens

Abstract

The objective of the study was to detect genetic marker associated with egg production trait in Pradu Hang Dam and Chee chickens. A total of 230 Pradu Hang Dam and 220 Chee represented the sample size. 24BP-PRL and 5FA-PRL, BMPR-IB, cGH, GnRHR and NPY were genotyped by PCR and PCR-RFLP methods, respectively. The result revealed that in Pradu Hang Dam, the 5FA-PRL and 24BP-PRL genes were related with egg production trait (P<0.05) and 5FA-PRL has a major effect on egg production trait. However, the 5FA-PRL genotyping was more expensive and difficult than 24BP-PRL. Thus, 24BP-PRL might be appropriated as genetic marker for egg production trait as 24BP-PRLshowed similar effect as 5FA-PRL. On contrary, non significant (P>0.05) association between genes and egg production trait was observed in Chee.
