Abstract. Phytobiotics have a significant impact on the health of animals and increase productive qualities. At the same time, the question of studying the effect of individual herbal supplements on the physiological and productive indicators of poultry remains open. In this regard, the purpose of this study was to evaluate the effect of combinations of 4-hexylresorcinol with other herbal preparations on weight growth, as well as morphological and biochemical blood compositions of broiler chickens. Methods. The studies were conducted on 125 heads of 7-day-old broiler chickens (cross Arbor Icres, 5 groups, n = 25). Experimental scheme: control group – basic diet (BD); I experimental (BD + 4-hexylresorcinol; at a dosage of 0.5 mg /kg of live weight per day); II experimental (BD + 4-hexylresorcinol + gamma-octalactone at dosages of 0.4 mg/kg and 0.1 ml/kg of live weight per day); III experimental (BD + 4-hexylresorcin + 7-hydroxycoumarin in dosages of 0.1 mg/kg and 0.15 ml/kg of live weight per day); IV experimental (BD + 4-hexylresorcin+gamma-octalactone + 7-hydroxycoumarin in dosages of 0.05 mg/kg, 0.15 ml/kg and 0.01 mg/kg of live weight per day). The scientific novelty lies in the fact that for the first time the effect of the use of the herbal preparation 4-hexylresorcin in combination with other phytobiotics on the physiological parameters of broiler chickens has been studied. Results. It was found that chickens of the I, II and IV experimental groups at the age of 35 days were superior in live weight to individuals from the control group, with the maximum difference in relation to broiler chickens receiving a basic feeding diet. The introduction of the tested herbal preparations into the diet of the experimental bird had an ambiguous effect on the morphological and biochemical composition of the blood, which was expressed in the form of an increase in the level of individual elements with a significant decrease in others.
Keywords: broiler chickens, 4-hexylresorcinol, 7-hydroxycoumarin, gamma-octalactone, weight growth, morphological and biochemical parameters of blood.
