The objective of this study was to evaluate the effect of Halothane genotype (CC and CT) on growth performance, feed conversion ratio and carcass performance of stress negative Pietrain intact males raised at Animal farm of Vietnam National University of Agriculture from September 2013 to December 2014. A total of 51 males were used. Growth performance and feed conversion ratio were collected from 15 pigs (9 CC and 6 CT) whereas carcass performance were collected from 10 pigs (5 CC and 5 CT). The average daily gain (ADG) and feed conversion ratio (FCR) of stress negative Pietrain intact males were 510.19 g/day and 2.69 kg, respectively. The difference was not significantly different for ADG and FCR between CC (533.60 g/day and 2.57 kg) and CT (534.68 g/day and 2.63 kg). The lean meat percentage was not significantly different between CC (64.12 percent) and CT intact males (64,39 percent). Halothane genotype did not affect carcass characteristics (P0.05). The results indicate that individuals with halothane genotype CC and CT can be choose for the breeding without affecting the growth performance, FCR and carcass characteristics.
