At the moment, an important issue for medicine and veterinary sciences is the lack of iodine and selenium in human and animal bodies. The problem of I, Se, and S deficiency in livestock has not been solved yet, which motivates the development of new effective compounds of these elements. Particularly noteworthy are the citrates of minor nutrient elements included in mineral premixes and feed additives used to balance mineral nutrition in the diets of animals and poultry. The purpose of this paper is to study the efficacy of different doses of I, Se, S citrate on the intensity of metabolic processes in the body of chicken broilers before and after the intragastric introduction of E. coli. It was found that watering of chicken broilers with I, Se, S citrate has antibacterial action. As a result of the conducted studies, it was revealed that the applied doses of I, Se, S caused both prophylactic (E2) and therapeutic (E4) effect on the development of colibacillosis in broiler chickens. This effect is more pronounced with higher doses of Iodine (20 μg/dm3 ) in I, Se, S citrate for therapeutic purposes, which contributed to the 100% preservation of the chicken population. High metabolic activity of low doses of I, Se, S citrate with a content of 2.5 μg I dm3 was noted. It provided the highest weight gain of chickens and reaching 780 g on the 35th day of growing, or 121.5% versus control and 788.4 g (119.9% versus control) on 42nd day of growing in the vivarium. The obtained data indicate a positive influence of watering I, Se, S citrate with a content of 20 μg I/dm3 , which was characterised by 100% preservation of chickens throughout the growing period
