The study was conducted to determine the suitable energy and protein levels in diets of commercial
Xao Va pigs at 2 growth stages: 3-15 kg and 15 kg-slaughter weight. The experiment was arranged
according to a completely randomized design with 2 factors per 12 experimental units (2 energy levels x 2
protein levels x 3 replicates/each combination of energy level and protein level), each experimental unit was
a group of 6 pigs (3 castrated males and 3 females). Two energy levels are 3,000 and 3,100 Kcal ME/kg
of feed during the entire growing periods. Two crude protein levels are 17 and 18% at the 3-15kg stage
and 16 and 17% at the 15kg-finishing stage. The results showed that, pigs consuming the diet with the
energy level of 3,100 Kcal ME/kg of feed grew faster and consumed less food than the other group, in
detail: the final weight reached 26.18-26.45 vs. 24.82-25.18 kg/head (P=0.001), ADG was 125-127 vs. 118-
120 g/day (P=0.000), FCR was 4.33-4.35 vs. 4.48-4.49kg feed/kg ADG (P=0.002). In contrast, crude
protein levels did not affect the growth and feed consumption of pigs in this experiment. There was no
influence of the interaction between energy and protein on the study parameters in both periods. Thus, a
diet with 3,100 Kcal ME/kg feed and 17%CP at the weaning-15kg period and 3,100Kcal ME/kg feed and
16%CP at the 15kg-finishing period should be applied for the commercial Xao Va pigs to improve their
growth and feed efficiency.
