Prolactin (PRL) - is a peptide hormone. It effects on
metabolic processes in mammals and birds. Indel
genotype mutations in a prolactin gene were
determined in 595 hens and cocks. Polymerase chain
reaction (PCR) were used. We studied four different
breeds: Cornish, White Russian, Pushkin, Yurlov
crower. Homozygous of insertion II, homozygous
deletion of DD and heterozygous ID were observed in
all groups. The differences in frequencies of genotypes
and alleles were observed in all groups. Homozygotes
II and allele I (frequency is 0,83) were the most
common for Russian white chickens with high egg
production and the lack of the instinct of incubation.
Prolactin gene deletion was more common for beef
Cornish. The frequency of D allele was 0,84. Pushkin
chickens proved to be closer to the egg type. A
significant number of heterozygotes with this mutation
were noted in a population of Yurlov crower. It is
recommended to use gene prolactin as a marker of
productive indicators in chickens
