The Effects of Saturea and Thyme Medicinal Plants with or without Enzyme on Performance, Blood Parameters in Broiler Chickens

This experiment was conducted to assess the effects of using Thyme, Saturea, medicinal plants with or without enzyme on performance, blood parameters in broiler chickens. This experiment was conducted in a completely randomized design with 480 broiler (Ross-308) in 8 treatments and 3 replicates (n=20) for starter (1-21 days) and grower period (21- 42 days). The experimental diets contained: 1, Control (basal diet); 2, Containing 1% Thymus; 3, containing 1% Saturea; 4, Containing 0.05% enzyme; 5, using of 0.5% Thymus 0.5% Saturea; 6, 1% thymus 0.05% enzyme; 7, 1% Saturea 0.05% enzyme); 8, 0.5% Thymus 0.5% Saturea.05% enzyme. The results of this experiment showed that thyme and saturea and enzyme supplementation significantly increased the amount of body weight gain, and improved feed conversion ratio in grower (21-42 days) and whole period (0-42 days), in comparison to control diet (P
