Comparative evaluation of the integrative parameters of the bone tissue of lower limbs of broiler chickens when using osteotropic additives in the diet

Abstract

The article presents the results of studies of the comparative assessment of the bone tissue integrative parameters of the lower limbs of broiler chickens of the Arbor Acres cross when using in their diet the drug siliostin and feed additives for correcting mineral metabolism – acidic calcium and bentonite clays of the Kantemirovskoye deposit of the Voronezh region. Based on the measurements of the width of the sum of the cortical zone of the diaphysis of the X-ray images of the bones, the assessment of its average brightness, as well as the assessment of the average brightness of the middle part of the bone, it was found that in hens and cocks of meat poultry during the period of intensive growth and development, the use of various feed mineral additives leads to unequal changes in the structure and degree of mineralization of the femur and tibia bones of the extremities. Moreover, the most stable positive picture of changes was noted in chickens treated with siliostin + acidic calcium. The absence of a stable picture from other radiological parameters should be considered as a part of complex biochemical processes in the body that accompany the growth and development of young poultry.
