Effects of Compound Herbal Additives on Piglet Growth Performance and Serum Biochemical Indices and Serum Biochemical Indexes of Piglets
The experiment aims to investigate the effects of Chinese herbal medicine additives(mainly for replenishing qi,strengthening spleen,and nourishing blood)on the growth performance,mortality index,diarrhea index,and serum biochemical indicators of weaned piglets.The two hundred and forty weaned pig-lets at 40 days of age were randomly divided into six groups(half male and half female),with five replicates in each group and eight piglets in each replicate.The control group was fed with a basic diet,test 1 group was supplemented with antibiotics on the basis of basal dietsantibiotics,while the test 2,test 3,test 4,and test 5 groups were added with 0.5%,1.0%,1.5%,and 2.0%fermented compound Chinese herbal in the diet,respectively.The pre-trial period lasted for 15 days and the experimental period lasted for 49 days.The results showed as follows:compared with the control group,the average daily gain(ADG)in test 2,test 3 and test 4 were significantly increased(P<0.05),and the diarrhea rate in control and test 1 groups were signifi-cantly higher than other four groups(P<0.05).However,we detected no significant difference in serum between the all groups with respect to the activities of the content immunoglobulin A(IgA),immunoglobulin G(IgG),and immunoglobulin M(IgM)(P>0.05).Serum alanine transaminase(ALT)activity was sig-nificantly lower in test 3,4,and 5 groups than in the control group(P<0.05),and the difference between test group 1 and the control group was not significant(P>0.05).Overall,in practical produc-tion,it is more appropriate to add 1.5%compound Chinese herbal medicine to the diet of weaned piglets.
