Abstract:

This experiment was conducted to study the effect of supplementary feeding milk replacer on growth performance,nutrient digestibility,serum biochemistry indexes in piglets during lactation,and explore the feasibility of shorten the weaning age of piglets by feeding milk replacer. One hundred and twenty (twelve litters) 5 days old piglets with average body weight of (3.12±0.63)kg were assigned into two groups with sixty piglets per group (six litters)and one litter of piglets per replicate. The piglets in control group received supplementary creep feed and were weaned on 28 days old,whereas the piglets in experimental group received supplementary creep feed and milk replacer (creep feed:milk replacer=1:1) and were weaned on 21 days old. The piglets in experimental group were continued feeding with creep feed and milk replacer until 28 days old. All piglets were fed with same diets from 28 to 70 days old. The results showed as follows:① Comparing with control group,the body weight of piglets in experimental group were not significantly changed at 5,21,28 and 70 days old (P>0.05),ADFI and F/G were extremely significantly or significantly increased during 5 to 21 days old,22 to 28 days old and 5 to 28 days old (P < 0.01;P < 0.05),while ADG was extremely significantly decreased during 22 to 28 days old compared with control group (P<0.01).② The digestibility of GE,DM,OM and EE of experimental group were significant higher than control group (P<0.05).③ All serum biochemistry indexes between the two groups had no significant differences (P>0.05). In conclusion,supplementary milk replacer feeding could increase the feed intake and dietary digestibility of weaned piglets. The age of wean could be forward to 21 days old according to the final body weight of weaned piglets when fed milk replacer supplementation.
