Fig. 4From: Genome-wide association study reveals putative role of gga-miR-15a in controlling feed conversion ratio in layer chickensExpression of gga-mir-15a for hens with high, medium and low feed conversion ratio. a The phenotype of feed conversion ratio for hens selected from high, medium and low feed conversion ratio group. b Expression of gga-mir-15a for the selected hens. Gene expression is presented relative to 5Â s RNA expression and normalized to a calibrator. **PÂ <Â 0.01. Six birds per group were available for the analysisBack to article page
