    <p>Аннотация. Исследование направлено на изучение влияния пробиотического штамма Bifidobacterium longum на содержание химических элементов в биологических тканях цыплят-бройлеров на фоне минералдефицитной диеты. Методология и методы. Исследования были проведены на цыплятах-бройлерах кросса Арбор-Айкрес в возрасте от 7- до 42-дневного возраста. С 21-суточного возраста цыплят методом аналогов были сформированы две группы по 15 голов в каждой, исследуемая птица содержалась на дефицитной по минералам диете. Птица опытной группы получала жидкий пробиотический препарат «Соя-бифидум» в дозировке 0,7 мл/кг корма. Особенности обмена химических элементов определяли путем исследования содержания элементного состава печени, грудных и бедренных мышц по 25 показателям. Результаты и практическая значимость. Дополнительное включение пробиотического штамма в рацион способствует максимальному выведению токсичных элементов, тем самым снижает интоксикацию всего организма. Так, установлено, что пробиотический штамм Bifidobacterium longum способствовал достоверному снижению в печени алюминия на 34 % (р = 0,048), свинца – на 50 % р = 0,008), олова – на 67 % (р = 0,0064), в грудных мышцах – алюминия на 54,6 % (р = 0,005), кадмия – на 55,6 % (р = 0,005), в бедренных мышцах – кадмия на 50 % (р = 0,006), свинца – на 75 % (р = 0,001), стронция – на 50 % (р = 0,013) относительно данных показателей в контрольной  группе. Научная новизна. Впервые описаны особенности элементного обмена по 25 показателям цыплят-бройлеров при введении пробиотических препаратов на фоне минералдефицитной диеты.</p>

    <p>Abstract. The study is aimed at studying the effect of the probiotic strain Bifidobacterium longum on the content of chemical elements in the biological tissues of broiler chickens against the background of a mineral-deficient diet. Methods. The research was conducted on cross Arbor-Icers broiler chickens between the ages of 7 and 42 days old. From the 21-day-old age of chickens, two groups of 15 heads each were formed by the method of analogs, the studied bird was kept on a mineral-deficient diet. Poultry of the experimental group received a liquid probiotic preparation “Soy-bifidum” in a dosage of 0.7 ml/kg of feed. Features of the exchange of chemical elements were determined by studying the content of the elemental composition of the liver, thoracic and femoral muscles on 25 indicators. Results and practical significance. The additional inclusion of the probiotic strain in the diet contributes to the maximum elimination of toxic elements, thereby reducing the intoxication of the entire body. Thus, the probiotic strain Bifidobacterium longum contributed to a significant decrease of aluminium in the liver by on 34 % (p = 0.048), lead – 50 % (p = 0.008), tin – 67 % (p = 0.0064), aluminium in the thoracic muscles by 54.6 % (p = 0.005), and cadmium by 55.6 % (p = 0.005), cadmium in the femoral muscles by 50 % (p = 0.006), lead by 75 % (p = 0.001), strontium – 50 % (p = 0.013) compared to such values in the control group. Scientific novelty. There were described the features of elemental metabolism by 25 indicators of broiler chickens with the introduction of probiotic drugs against the background of a mineral-deficient diet for the first time.</p>
