The experiment was divided into 2 groups: in the experimental group, the piglets were weaned at 18 days of age and in the control group, the piglets were weaned at 25 days of age. The results showed that the early weaning of piglets had a positive effect on some growth parameters of piglets, the absolute growth in the experimental group was higher than that in the control group at the period 31-45 days of age (336.30 g/head/day in experimental group, 323.30g/head/day in control group) (P<
0.05) and 46-60 days of age (504.70 g/head/day in experimental group, 494.20 g/head/day in control group) (P<
0.05). In addition, the survival rate of piglets from SS-60 days of age of the experimental group was 94.16%/which was higher than that of the control group (92.99%) (P>
0.05). At the same time, the percentage of piglets with diarrhea in the experimental group was lower than that in the control group, but there was no statistical difference (P>
0.05). Therefore, early weaning of piglets has increased the growth performance without affecting the susceptibility of piglets to diarrheal disease.
