Abstract: 【Objective】 The aim of this experiment was to investigate the effects of different concentrations of curcumin supplementation on production performance,serum biochemical indexes and apparent feed digestibility of growing Hainan Tunchang pigs.【Method】 Eighty Hainan Tunchang pigs weighted 35.88 kg±0.25 kg were randomly divided into five groups,each group had 4 replicates,and 4 pigs for each replicate.The pigs in control group were fed with basal diet,and the pigs in antibiotic group were supplemented with 300 mg/kg mucocitractin sulfate in basal diet.The pigs in other 3 treatment groups were supplemented with 200 (Cur group 1),400 (Cur group 2) and 600 mg/kg(Cur group 3) curcumin in the basal diet, respectively.The pre-feeding period was 7 days,and the trial period was lasted 50 days.The experimental pigs were weighted on the 51 st day morning for the calculation of growth performance.Six pigs’serum in each group were randomly collected for the measurement of serum biochemical indicators.The fresh feces of 3 pigs were randomly collected for each repeat to determine the apparent digestibility of feed nutrients.【Result】 Compared with control group,average daily weight gain (ADG) was improved by 23.82% (P<0.05),the ratio of feed and gain(F/G) was reduced by 20.06% (P<0.05),the activity of serum AST and DAO content was reduced by 22.23% and 29.31%,respectively (P<0.05),and serum IgA concentration was increased by 21.14% (P<0.05) in Cur group 3. Compared with antibiotic group,the ADG of pigs was improved by 23.09% (P<0.05),the apparent digestibility of crude fiber was increased by 42.14% (P<0.05), and the activity of serum AST was reduced by 31.75% (P<0.05) in Cur group 3.Compared with control and antibiotic groups,ADG of Cur groups 1 and 2 showed no significant difference(P>0.05).Compared with control group,both of serum’D-lactic acid and DAO concentrations in Cur groups 1 and 2 were significantly reduced (P<0.05),and the apparent digestibility of crude fiber of Cur group 2 was significantly increased than control and antibiotic groups(P<0.05).【Conclusion】 Adding with 600 mg/kg curcumin could increase the growth performance and apparent digestibility of crude fiber in growing Hainan Tuncahng pigs,and improve the immune state of pigs,which could play an potential role for replacing antibiotics.
