Genetic parameter of Brahman cattle was estimated on birth weight (BW), Weaning weight (WW) and yearling weight (YW). One thousand three hundred and eighty one records were collected during 1987 to 1994 from Prachinburi, Ubon Ratchatani and Mahasarakam Livestock breeding station. Genetic parameters, namely heritability genotypic correlation and phenotypic correlation were estimated from paternal half sib data. The result showed that heritability estimates for BW, WW and YW were 0.20+-0.07, 0.36+-0.11 and 0.21+-0.08 respectively. The genetic correlation and phenotypic correlations between BW-WW, BW-YW were 0.44+-1.13, 0.18+-0.23 and 0.43+-0.16; and 0.42+-0.03, 0.23+-0.03 and 0.59+-0.03, respectively.
