Sažetak
Prolactin receptor gene was found in pig chromosome 16, and it is one of the genes with a significant effect on
reproduction traits in sows. The objective of the research was to determine polymorphism of the prolactin receptor
gene in pigs of two maternal breeds: Polish Landrace and Polish Large White, as well as analyse relations between
particular allelomorphic variants, and reproduction traits of examined sows. Two PRLR gene alleles, A and B, were
isolated, they were obtained after AluI restriction gene digestion of the PCR product with the length of 163 bp;
furthermore, three genotypes were identified: PRLRAA – 85, 59, 19 bp; PRLRAB – 104, 85, 59, 19 bp; PRLRBB – 104,
59 bp. We assessed 122 sows, in terms of their age at the first farrowing, as well as the sizes of the two subsequent
litters. No statistically significant differences were found in the examined reproduction traits in sows with different
allelomorphic relations, both within each breed and between breeds. Obtained results indicate that it is necessary to
conduct further research on a larger animal group.
