    Abstract


    This study was conducted to estimate heritability of growth traits andlean meat percentage of stress negative Piétrain pigs raised in Dong Hiep livestock farm, Hai Phong province and animal farm of Hanoi University of Agriculture. Sample sizes were 2093, 1380, 895, 494, 338 and 470 for body weight at birth, weaning,60 days, 7.5 months, average daily gain (ADG) and lean meat percentage respectively. Two softwares (Harvey andMTDFREML) were used to estimatethe heritability for each trait. Results showed that stress negative Piétrain pig had a high lean meat percentage(64.12%), however ADG was low (489.54 g per day) due to selection programme and small population. Heritabilitis of body weight at birth, weaning, 60 days, 7.5 months of age, ADG and lean meat percentage were 0.13, 0.12, 0.25, 0.23, 0.31 and 0.19 respectively. These values ​​are consistent with previous studies, except the heritability of lean meat percentage relatively low.
