| Popis: | The productivity and quality increase of the animal products is coming to be of big economic interest. The prolactin (PRL) is an essencial hormone for the reproductive sucess and its receptor (PRLR) has been detected in several tissues (Kelly et al., 1991). The PRLR gene has been recently mapped to pig chromosome 16 (Vincent et al., 1997).This research was aimed at analyzing the PRLR genotypical frequency in three different swine races, Landrace, Large White and Pietrain and correlate the genotypes with characteristics of economic interest. It was analyzed 124 animals. The DNA was extracted from the pig blood and submited to PCR-RFLP technique, to the genotypes determination of the prolactin receptor gene. The statistics analysis showed that the PRLR genotypes had an effect on the daily average weight of the Landrace race (p |
