Abstract
The data on Holstein Friesian x Sahiwal cows maintained at Military Dairy Farm, Pimpri, Pune (Maharashtra) were collected for the present study. A total of 9094 lactation records belonging to 3425 Frieswal cows born to 239 sires were collected. The data available from various records viz. pedigree register, history sheets, lactation register, dry cow register and disposal register were collected and compiled. The data were standardized by removing the sires with less than five progenies. The breeding values of the top 15 sires were predicted up to first three lactations on the basis of daughter’s performance by using Best Linear Unbiased Prediction (BLUP) as given by Henderson (1976). It was observed that overall mean (µ) for breeding value of sires up to three lactations predicted using BLUP was 9530.12± 99.89 kg. The sire DEVTA was ranked first on the basis of breeding values estimated by BLUP on the basis of daughter’s performance (11061.89 ± 938.8 kg) whereas lowest predicted breeding value was recorded for sire SPAM (6724.92 ± 923.47). The overall mean (µ) for breeding value of sires up to five lactations predicted using BLUP was 16538.28 ± 195.22 kg. It was observed that the predicted breeding value of sire DEVTA was highest while the breeding value of sire SPAM was lowest amongst all sires studied.
