Performance records of 1085 crossbred cattle daughters of 57 sires maintained during 1974-2004 at Instructional Dairy Farm of G. B. Pant University of Agriculture & Technology, Pantnagar were used to evaluate sires for first lactation and life time performance traits. The data were analyzed to estimate the breeding values of sires using least squares methods (LSM), best linear unbiased prediction (BLUP) and derivative free restricted maximum likelihood (DFREML) method. The average breeding values of sires estimated by all three methods were similar and estimated for AFC, FLP, FDP and FCI as 1359.95 days, 356.56 days, 177.58 days and 534.15 days respectively and for HL, TLL and LTMY as 1641.30 days, 1320.20 days and 9110.30 kg respectively.
