The experiment was carried out on Starbro chickens divided randomly into 5 groups, each in 4 replications comprising 45 birds. Reared period was performed during 51 days. All chickens were fed semi ad libitum with the same mixtures: starter, grower and finisher. Group 1 was treated as control. Chickens from groups 2-5 received for drinking aqueous herb extracts made from milfoil, melissa, St. John's wort or nettle in amount which corresponded to the supplement of 1.5 percent of air-dry herbs into mixtures.
