An investigation was done to evaluate the effects of adding green tea probiotics, Alisma canaliculatum probiotics and fermented Kelp meal on the growth performance and immune response in sows and piglets. A total of 32 pregnant sows were assigned to 4 treatments in 8 replications with 1 sow as a replicate in this experiment from 2 months before parturition to 28 days after parturition. Three hundred nineteen(319) piglets were produced from experimental sows after parturition. The dietary treatments were CON group(without antibiotics), GTP(basal+green tea probiotics, 0.5% of the diet), ACP group(basal+Alisma canaliculatum probiotics, 0.5% of the diet) and FKM group(basal+fermented Kelp meal, 0.5% of the diet). Litter size and body weight at birth and weaning size and body weight at weanling in piglets were greater in additives group compared to CON group but no statistical differences were found(P>0.05). Diarrhea score showed a decreasing tendency with three additives groups compared to CON group. The lymphocytes in blood of sows fed ACP and FKM group were significantly higher compared to CON group (P<0.05), and the MID of GTP and FKM group were significantly lower compared to CON group(P<0.05). The serum IgG concentration in sows tended to increase with additives groups compared to CON group and the serum IgA and IgM concentration in GTP and FKM group were significantly higher compared to ACP group(P<0.05). The cortisol levels showed a decreasing tendency in additives groups without statistical differences among the groups(P>0.05). Based on these observations, it can be inferred that the GTP and FKM may have such efficacy as antibiotics in growing pigs.
