The effects of bioactive additive based on aqueous extract of Siberian fir tree on the morphological and biochemical blood parameters in broilers
The effects of bioactive additive based on aqueous extract of Siberian fir tree (applied with drinking water since 1 to 40 days of age in doses 1.0 and 2.0 L/t of water) on the morphological and biochemical blood parameters in Ross-308 broilers were studied. It was found that after 40 days of the application the additive in a dose-dependent manner significantly (though still within the respective physiologically normal ranges) increased concentrations of red blood cells and hemoglobin in blood; concentrations of total protein, albumins, triglycerides, glucose, total calcium, inorganic phosphorus, and iron, albumins/globulins ratio, activities of aspartic and alanine transaminases in blood serum. The conclusion was made that the additive beneficially intensifies the metabolism of protein, carbohydrates, and minerals in broilers.
