An experiment using 164 crossbred pigs born to 20 first-parity sows was conducted to evaluate the growth performance of piglets in four weaning management regimens: T1, conventional weaning at 56 days; T2, early weaning at 28 days; T3, split-weaning of the heavier half of the litter at day 28, the remaining half being weaned at 56 days; and T4, split-weaning of the lighter half of the litter at 28 days, with the animals kept on a special nutrient diet up to 56 days, and the heavier half being weaned at 56 days. Split-weaning of the lighter half in combination with feeding a special nutrient diet resulted in an increase of average daily gain of 21% from day 28 to day 140 compared to conventional weaning and of 36% compared to early weaning at day 28. Compared to the control (T1), the average weights of piglets at the 140th day in groups T4 and T3 were 19.6% and 6.16%, respectively, higher, whereas that of the T2 was 8% lower. It is concluded that feeding a special nutrient diet to lighter pigs is beneficial in overcoming the post-weaning lag and enables maximal weight gain.
