Modulation of Plasma Antioxidant Activity in Weaned Piglets by Plant Polyphenols

摘要: This study was conducted to evaluate the effect of plant polyphenols (PP) on antioxidant activity in weaned piglets. First, a uniform design, one optimising an experimental technique that can rationally arrange concentrations mixture components, used obtain best PP apple, grape seed, green tea and olive leaf based vitro capacity inhibitory action bacterial growth. Second, optimised tested vivo with efficacy trial The optimal effects mix were observed when tea, carrier (silicon dioxide) accounted for 16.5, 27.5, 30, 2.5 23.5%, respectively, mixture. Forty-eight piglets randomly allocated two dietary treatments (6 replicates 4 each per treatment) fed control diet (CTR) or CTR supplemented 0.1% Dietary did not affect growth performance compared group. Plasma total protein, urea nitrogen lysozyme content affected by treatment. No differences E. coli Clostridia counts faeces caecum between groups observed. A reduced malondialdehyde concentration group day 21 (P=0.02). In conclusion, prepared has potential improve plasma activity.
