Summary. In connection with global environmental pollution, the use of intensive technologies in the animal industry animals’ health status study is becoming particularly urgent in areas with high development pressure and search for methods to reduce its negative impact. Prolonged exposure of toxicants on the animal organism, oppressive or stimulating the immune system, reduces the natural resistance and the development of immunodeficiency conditions, which reduces the use of the biological potential of the animals. To explore the possibility of easing the pressure on the toxigenic organism in productive animals of contaminated by industrial emissions territories authors conducted with enterosorbents, which were introduced into diets of animals. Polysaccharides derived from marine aquatic: zosterine (sea grass Zostera marina L.), sodium alginate (brown alga Laminaria japonica Aresch), were used in the researches. All three groups of calves of the age of 6 months were sampled for biochemical and immunohaematological analyzes. Biochemical study of the blood of calves in the beginning of the experiment revealed a low level of carotene and high level of cholesterol. Urea and total protein levels were at the lower limit of normal. Albumin content was also reduced, while gamma globulins are slightly higher than the average indices. This state may indicate a breach of protein synthesis function, impaired lipid exchange due to chronic intoxication. Three months after the feeding of preparations there was a tendency of calcium, phosphorus, iron levels increase in the blood. It was established that a greater effect is the use of alginate and zosterin at the final fattening stage, that gives reason to recommend them for general practice.
Keywords: ecotoxicants, intoxication, correction, heavy metals, natural resistance, biological potential, biochemical blood analysis, carotene, urea, total protein.
