The breeding value evaluation of sires on body conformation of female progeny of European Black - White cattle by the use of linear methods

1992

The female progeny of European Black-White cattle was investigated. Heifers were daughters of eight sires of different genotype, two of which were of Holstein-Friesian breed (D and F), while H-sire had 84, A-, C-, E-sires 62, B-sire 56 and G-sire 50 of Holstein-Friesian genes. Body mass measurement and taking of the exterior measures were done at 4 and 9 months of age. Analysis of data was carried out by the use of three linear methods and these are: Least Squares Method (LS), Best Linear Unbiased Prediction (BLUP), and Mixed Model or Sire Model (SM). Concerning the total evaluation of rank, obtained by the use of all the three methods, it can be stated that the Holstein sires and those with the highest percent of Holstein-Friesian genes were the best. The lowest rank was given to sires with the lowest percent of Holstein-Friesian genes.
