Abstract. The purpose of the study investigates the impact of Fucus vesiculosus seaweed extract in the diet of the white-and-black young cattle on the additional live weight gain and stimulation of nonspecific suppressor factors. Sixty calves aged 3 to 4 months were randomly divided into three groups, with twenty calves in each. Calves from the control group received standard diet. Those from two experimental groups received standard diet with additional 25 ml of the adaptogen of Fucus vesiculosus (experimental group I once a day, experimental group II – twice a day). Blood serum samples were taken from calves on the 0 and 30th day of the experiment. Authors assessed the lysozyme and bactericidal activity of blood serum, as well as the phagocytic activity of white blood cells. The objective is to analyze the effectiveness of adding the adaptogen of Fucus vesiculosus to the diet of young white-and-black cattle in order to increase their live weight gain. Methods. During the course of the study, the authors have used analytical, biometric, and statistical methods, as well as their own research. The study’s scientific novelty consists in analyzing the effectiveness of using the adaptogen of Fucus vesiculosus in the diet of young cattle for the first time ever. Results. The authors have found that, in order to stimulate the degree of live weight gain in young cattle and to preserve and enhance their metabolism, it is recommended to use the Fucus vesiculosus seaweed extract. Adding the adaptogen to the diet of calves in both experimental groups has led to the increase of 8.7 % to 15.9 % in live weight gain (based on the amount added) compared to calves from the experimental group. The number of NSFs in the experimental group II was higher than in the experimental group I and the control group.
