Effect of dairy-yeast prebiotic on growth performance and antioxidant capability of juvenile starry flounder Platichthys stellatus
摘要
Abstract
An 8-week feeding trial was conducted to study the effect of dairy-yeast prebiotic (Grobiotic-A) on the survival rate,growth performance and antioxidant capacity of juvenile starry flounder Platichtahys stellatus.A total of 540 fish at body weight of 15.05±0.04 g were randomly allocated into six groups with three replicates and each replicate contained 30 fish.The fish were fed diets supplemented with 0,0.4％,0.8％,1.2％,1.6％ and 2.0％ dairyyeast prebiotic,respectively.The results are shown as follows:1) weight gain rate (WGR),specific growth rate (SGR),feed intake (FI),protein efficiency rate (PER) and condition factor (CF) increased whereas feed conversion ratio (FCR) decreased significantly (P＜0.05) with the supplementation of dairy-yeast prebiotic in diets.However,there were no statistical differences in viscerosomatic index (VSI),hepatosomatic index (HSI) (P＞0.05) ; 2) compared with the control,the activity of catalase (CAT) and total anti-oxidation capability (T-AOC) in serum and liver,and superoxide dismutase (SOD) and anti-superoxide anion activities (T-AOC) in serum were significantly increased (P＜0.05),while the malondialdehyde (MDA) content in serum and liver of fish fed diets supplemented with dairy-yeast prebiotic was significantly decreased (P＜0.05).These results indicated that dairy-yeast prebiotic positively influenced the growth performance and anti-oxidation of juvenile starry flounder in this experiment.Quadratic regression of SGR indicated that the optimal supplementation level of dairy-yeast prebiotic in juvenile starry flounder diet was 1.32 ％.关键词
