Analysis of allocation of haplotypes in locuses of prolactin and insulin-like growth factor-I in populations of hens of different breeds

Abstract

The purpose. To study frequency of allocation of haplotypes in locuses of prolactin and insulin-like growth factor-I in populations of hens of breeds Plimutrok bilyi (line G-2), Borkivska barvysta (line A), Poltavska hlynysta (line 14) and Rod-island chervonyi (line 38). Methods. PCR, PCR-RLFP. Results. Frequencies of haplotypes in locuses of prolactin and insulin-like growth factor-I in the tested populations of hens are specified. Conclusions. For egg hens it is characteristic predominance of frequency of haplotype IC by locus of prolactin, while for breeds of combined direction of productivity — of haplotype DT. By locus of insulin-like growth factor-I for populations of hens of breeds Plimutrok bilyi and Rod-island chervonyi it is characteristic predominance of frequency of haplotype C2A, for all other lines — of haplotype C2C.
