The present study was conducted to estimate the genetic parameters (heritability and genetic correlation) and breeding value of Brahman crossbred cattle (50%) of Bangladesh. Data on 5662 Brahman graded calves (50%) were collected from the records maintained by Department of Livestock Services from the eight areas of the country. Basic statistical analyses were performed by using Statistical Analysis System (SAS) version 9.1.3. Heritability and genetic correlations were estimated with Variance Component Estimation (VCE) 5.1.2 software and finally breeding values were measured with PEST software. Heritability (h2) estimates were 0.87, 0.59, 0.33, 0.33, 0.34, 0.34, 0.35 for birth weight (BW), Weight at 1-, 3-, 6-, 9-, 12- and 24-month (kg), respectively. Estimates of h2 for ADG from BW to 3-month (g), ADG from 3- to 6-month (g), ADG from 6- to 9-month (g), and ADG from 9- to 12-month (g) were found to be 0.53, 0.71, 0.69 and 0.68, respectively. Genetic correlations between growth
