The experiment was been performed in the sector of Nutrition and Animal Feeding discipline from Timisoara Didactic Station, on a 6 week period, beginning with hatching and finishing with 42 days of age, on 120 broilers divided into four experimental variants, each of them with 30 individuals. In LEU group was incorporated essential oils of Satureja hortensis, Mentha piperita and Hyperici herba 250 mg in 1 kg combined fodder, in LEP group was included in combined fodder structure a plants premix in 2%, in LEUP group was incorporated plants premix 2% +250 mg essential oil of Satureja hortensis, Mentha piperita, Hyperici herba in 1 kg combined fodder. After seric lizozime quntification was observed an increase with 303.46% in LEPU group, followed by LEU with 200.14%, results who demonstrated the presence of an immunological stimulation in broiler chickens. Increased values of seric properdine were observed in LEPU group, with 210.45% more increased in comparison with LM group, followed by LEU group, demonstrating that the changing of unspecific immune effectors values took place like a result of a exogenous substance with immunomodulator effect. Was also observed an easy increase of limfocytes in LPU group, but not so important like in first two determinations, if the experiment will continue, these values maybe will be significant increased, taking into consideration that these increases become more evident after a period of time after stimulation.
