Influence of Pik-antistress fodder additive on the content of macroelements in blood and tissue of broiler chickens of industrial growing

Growth and development of broiler chickens with intensive fattening, especially in the finishing period, reaches a peak in intensity. Under conditions of technological stress, mineral metabolism takes an active part in the development of the adaptation syndrome. Feeding the bird with a stress protector at a dose of 1269 g / t of feed led to a statistically significant increase in the ash content of the pectoralis minor, serum calcium, magnesium in the bone tissue and a decrease in phosphorus in the pectoralis minor; at a dose of 1693 g / t of feed, it significantly increased the ash content of the skin, the content of calcium in the blood, magnesium in the bone tissue, and reduced the level of phosphorus in the femoral muscles.
