Resumen: We have used the BovineHD Genotyping BeadChip to obtain high density genotypes (>700, 000 SNP after quality control) from 116 trios in five Spanish local beef cattle breeds. Linkage disequilibrium (LD) was meas- ured through the r2 statistic. Average r2 for adjacent markers in the five breeds were very close, around 0.52, and de- creased with increasing distance between markers, although in long distances some LD remained (0.07 and 0.05 for markers 200 kb and 1000 kb apart, respectively). At all distances the standard deviations were large and the shape of the distribution varied depending upon the marker dis- tance. Average r2 varied also between chromosomes. Pair- wise correlations between the r’s estimated in two breeds at short distances (5 kb) was in the rank of 0.6 – 0.7. Similarly to r2 estimates, this correlation decreased with increasing marker distance.
