The influence of purple sweet potato anthocyanin on indicators of chicken’s growth performance,immunity function and serum oxidation resistance
Abstract：The experiment select 40 one age healthy growing chickens, assigned to four treatment groups at random, each group has ten chicks.We feed different groups with different diets which are content of 0, 50, 100, 150 mg/kg purple sweet potato anthocyanin, to discuss the influence of different level of purple sweet potato anthocyanin on seedling period of growth, immunity performance and serum's antioxidant properties indexes in chicken.There are two times when allocating feeding experiment,one formal experiment period has 35 days,another advance experiment period has 7days.,when chickens were at age of 42 day,we separated bursa of Fabricius, and tested its immune function and oxidation resistance.Test results display that: (1)when purple sweet potato anthocyanin increase to 100 or 150 mg/kg,it play a significant role in aging 22 to 42 days at chickens (P<0.01),but in early growing when chickens are at age of 1 to 21 days,purple sweet potato anthocyanin can put on weight in chicken but it is not significant(P>0.05).(2) when fodders are contained of 100 mg/kg purple sweet potato anthocyanin ,there is a great increasing in indicators of SOD and CAT (P<0.01),but it is not obvious for GSH-Px and GSH (P>0.05). (3) when the foods which are contented of purple sweet potato anthocyanin increased to 150 mg/kg ,the immunity performance decreased,besides antioxidant capacity for example GSH-Px,GSH,CAT.
