Abstract. Title of the paper: Application of Echinacea-extract in pregnant and suckled sows
In an experiment with thirteen sows (echinacea: n = 6; control: n = 7), the influence of Echinacea purpurea treatment of pregnant and suckled sows on immune system, health status, growth performance, and carcass quality of the offspring (echinacea: n = 69; control: n = 79) was investigated. Echinacea was given as liquid feed supplement during the whole pregnant and suckling period of sows in six intervalls (5 days of treatment, followed by 2 weeks of break, respectively). During the treatment time the daily dosage per sow in echinacea-group was 0.125 ml preparation of echinacea extract (incl. solution)/kg body weight. To measure the concentrations of immunoglobulin G (IgG), immunoglobulin A (IgA) and C-reactive protein (CRP) in serum, blood samples were taken by punction of V. cava cranialis (sows and piglets) at different times. The treatment of sows resulted in immunostimulatory effects both in sows and piglets with highest changes in peripartal period. In one day old piglets, the concentrations of IgG, IgA and CRP were significantly increased in echinacea-group (P = 0.0004, P < 0.0001, P = 0.05, respectively). Up to day 70 of age, the rate of therapeutical treatments of piglets from echinacea-treated sows was decreased in tendency (P = 0.08). The growth performance and carcass quality of offspring was not influenced by echinacea treatment of sows.
