Влияние пробиотического штамма Bifidobacterium longum на содержание химических элементов в биологических тканях цыплят-бройлеров при минералдефицитной диете

Abstract

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.
