Deskripsi

Genetic parameters of number of piglets born alive (NBA) and gestation length (GL) were analyzed for 39798 Hungarian Landrace (HLA, 141397 records) and 70356 Hungarian Large White (HLW, 246961 records) sows. Bivariate repeatability animal models were used, applying a Bayesian statistics. Estimated and heritabilitie repeatabilities (within brackets), were low for NBA, 0.07 (0.14) for HLA and 0.08 (0.17) for HLW, but somewhat higher for GL, 0.18 (0.27) for HLA and 0.26 (0.35) for HLW. Estimated genetic correlations between NBA and GL were low, -0.08 for HLA and -0.05 for HLW.
