Effects of Polysaccharides on lymphocyte transformation & cytokine in Early-weaned Piglets
To study the effects of polysaccharides on lymphocyte transformation and cytokines in early-weaned piglets. Twenty-five “Duroc×Landrace×Yorkshire crossbred weaned piglets (21th day, 5.30±0.25kg BW) were randomly divided into 5 groups of 5 replicates per treatment and one piglet per replicate, fed with basal diet, basal diet plus 0.3 ％ pure polysaccharides of Atractylodes macrocephala koidz(PPAM)、0.6 ％crude compound polysaccharides(CCP) or 0.6 ％ polysaccharides of Atractylodes macrocephala koidz(CPAM), or adding antibiotic(15％ chlortetracycline 150mg/kg and 4％ flavomycin 50mg/kg)(ANT) respectively. The trial lasted for 14 days. The results showed as follows: the serum TNF concentration of PPAM and CCP were higher than that of CR(P<0.05); lymphocyte transformation and IL-2 of PPAM、CPAM and CCP were greater than that of CR ,but there were no significant differences (P>0.05) among them .These results from this study indicated that the dietary supplemented with PPAM and CCP could improve some immune indices of early-weaned piglets.
