The objective of this experiment was to study growth capacity and feed conversion ratio of GF337xGF24, GF280xGF24, GF399xGF24 crossbreds, in the period from 60 to 150 days old, in the industrial pig production system in the closed barn in Central Vietnam. The experiment was carried out on 230 crossbred pigs: GF337xGF24 (60 pigs), GF280xGF24 (84 pigs) and GF399xGF24 (86 pigs). The male:female ratio was 1:1. The experiment was arranged according to a completely randomized design with 18 experimental units (3 treatments * 6 replications). The experimental unit was pigs in each pen. Pigs were fed ad libitum according to growing phases. The results showed that GF337xGF24, GF280xGF24, GF399xGF24 crossbred pigs all had a high growth capacity and low feed conversion ratio. The body weight at 150 days old of the 3 crossbreds were between 91.4 and 97.2kg. The ADG in the period from 60 to 150 days old of the 3 crossbreds were between 793.8 and 823.0 g/day, in which the GF337xGF24 crossbred had superiority over the other two crossbreds. The feed conversion ratio of the 03 crossbreds were between 2.50 and 2.64kg feed/kg WG, in which the GF399xGF24 crossbred had a tendency to have the lowest feed conversion ratio. These crossbreds should be considered used in the industrial pig production system.
