On-site farm = farmer’s farm; On-station = Khon Kaen University experimental farm; BW0, BW4, BW8, BW12, and BW16 = birth weight, body weight at 4, 8, 12, 14 and 16 weeks of age (g); ADG0–4, ADG4–8, ADG8–12, and ADG12–16 = average daily gain during 0–4, 4–8, 8–12, and 12–16 weeks of age (g/day); BrC8, BrC12, and BrC16 = breast circumference at 8, 12, and 16 weeks of age (cm); * indicates a significant value (p < 0.05).
