The present study aimed to investigate the effect of milk liquid and powder supplements on piglets' performance, drinking behavior, and sow back-fat thickness change during the lactation period. There were four experimental groups (n = 24), and in the control group (n = 6), the piglets were suckled from the sow. For the supplemental groups (n = 18), milk powder (MP), milk liquid by feeding trough (MLFT), and milk liquid feeding by the bucket (MLFB). Data were collected with the weight of a total of 252 piglets measured at birth, at 14 days and at weaning (28 days), respectively. Sow back-fat thickness was measured 3 days before farrowing, 14 days after farrowing and at weaning. There were significant differences in average daily weight gain between day 14 and weaning age for the MP and MLFT (P < 0.05) but not in MLFB (P > 0.05). For approaches to the feeder, there were significantly higher in MP and MLFT groups (P < 0.05). Based on the examination of sow back-fat thickness, the back-fat loss was minimal (P < 0.05) in the MP and MLFT compared to the MLFB and the control. Giving the milk supplement as powder and liquid by feeding trough has increased the piglets' average daily gain and body weight on day 14th and the weaning day. Moreover, the back-fat thickness reduction of sows in the supplemental groups is lower compared to the control group.
