Abstract :

Four immunostimulating preparations (IPs) – Levamisol, Lidium KLP, Echinacea and Baymix Se+E
– were administered to Hy-Line hens aged 8 months (group I, II, III and IV, respectively, 10 birds in
each). The egg white lysozyme activity (LA) was determined before administering the IP, and next
17, 24, 31, 45 and 60 days after. All IPs led to an increase in the egg white LA which was maintained over a period of 45 (group II, III and IV) and even 60 days (group I) after administration. Levamisol was shown to be most effective IP, while Baymix Se+E the least.
