The heritability estimates were calculated from the records of birth weight(BW), adjusted weaning weight (WW), adjusted 2 years weight (2YW), preweaning average daily gain (ADG1) and gain on performance test (ADG2) by half-sib analysis and Hendersons method III for variance components analysis, and found the estimates to be 0.27(+ or -)0.10 for BW, 0.07(+ or -)0.05 for WW, 0.60(+ or -)0.23 for 2YW, 0.06(+ or -) 0.05 for ADG1 and 0.75 (+ or -) 0.10 for ADG2. The best linear unbiased prediction (BLUP), procedure for sire evaluation of the breeding value(BV) of 28 sires ranged from -1.50507 to 1.58384 for BW, -4.53084 to 4.08913 for WW, -21.41480 to 17.30860 for 2YW, -11.47710 to 10.13400 for ADG1 and -41.18040 to 46.6185 for ADG2. Positive correlation between breeding value of WW with ADG1 was 0.96386 (p<0.01), WW with 2YW was 0.57392 (p<0.01), WW with ADG2 was 0.42391 (p<0.05) and 2YW with ADG2 was 0.81199 (p<0.01). The prediction from breeding value of ADG1 from WW was ADG1 = -0.29960 + 2.93229 x 2YW (p<0.01), 2YW from WW: 2YW = -0.73189 + 2.49810 x WW (p<0.01), ADG2 from WW : ADG2 = -4.97820 + 4.85402 x WW (p<0.05) and ADG2 from 2YW: ADG2 = -3.5506 + 2.13632 x 2YW (p<0.01).
