Abstract：The study aims to explore the effects of different feeding strategies on the growth performance of different types of suckling piglets.The experiment was divided into two parts,namely,the effects of creep feed and milk replacer on ultra-early weaning dominant piglets,and the effects of supplementary feeding of creep feed and milk replacer on weak piglets.Sixty-six 14-day-old grade A piglets were randomly divided into two groups,with three replicates in each group and 11 piglets in each replicate.Both groups of piglets underwent ultra-early weaning treatment.The control group 1 was fed dry mixed feed,while the test group 1 was fed porridge feed and the water source was disconnected.Another 44 14-day-old weak piglets were randomly divided into two groups,with three replicates in each group,two replicates had seven piglets and one replicate had eight piglets.Neither group of piglets was weaned.The control group 2 was supplemented with dry mixed feed,while the test group 2 was supplemented with tidal mixed feed.The test periods of both experiments were 8 days.The results showed that there was no significant difference in the initial and final weight of piglets between the control group 1 and test group 1(P>0.05),and the survival rate was 100.00%in both groups.The average daily feed intake of creep feed and milk replacer,feed to gain ratio and diarrhea rate of the piglets in the test group 1 were all higher than those in the control group 1(P>0.05).There was no significant difference in the initial weight and final weight of piglets between the control group 2 and test group 2(P>0.05),among which the final weight of the test group 2 was slightly higher than that of the control group 2.The average daily feed intake,average daily weight gain and feed to gain ratio of piglets in the test group 2 were slightly higher than those in the control group 2,but the differences were not significant(P>0.05).The survival rate of piglets in the control group 2 and test group 2 was 100.00%,with no deaths,culling or diarrhea.Studies have shown that with the promotion of high-yield sows,ultra-early weaning(at 14 days of age)can be carried out for suckling piglets.After weaning,they can be fed with a mixture of dry feed containing creep feed and milk replacer without affecting their growth performance.Weak piglets in the later stage of lactation can be supplemented with tidal mixed feed to reduce the lactation pressure on sows and enhance the growth potential of piglets.
