Analysis of the parent index bulls and genotyping them on genes kappa-casein (CSN3), fat content (DGAT) and BLAD

The frequencies of alleles and genotypes at the loci of genes CSN3 and DGAT, an analysis to identify the animal carriers recessive allele BLAD, PCR-RFLP analysis. Also, an analysis of the parent index steers on genes CSN3 and DGAT, the correlation of different genotypes with milk performance of maternal and release fat.
