Effect of phytobiotics in the diet on zootechnical and biochemical parameters of broiler chickens

The article is devoted to the assessment of the productivity and biochemical composition of the blood serum of broiler chickens against the background of the use of phytobiotic feed additives. For the study 100 seven-day-old broiler chickens of the Arbor Acress cross were selected. According to the principle of pairs of analogues, chickens were divided into four groups. Phytobiotic "Butitan" was added to the basic diet of the I experimental group at a dosage of 500 mg / kg of feed, Oreganum was added to the diet of the II experimental group at a dosage of 200 mg/ kg of feed, "Probiocide-Phyto" was added to the diet of the III experimental group at a dosage of 1 g / kg of feed. The results of the study demonstrated that phytobiotic feed additives are not only an alternative to antibiotics, hormones and other growth stimulants, but also an effective method of forming productive qualities in broiler chickens. The use of phytobiotic feed additives is a promising area that can be recommended for introduction into poultry farming practice.
