THE MORPHOLOGICAL ADAPTATION OF HEART STRUCTURES AND BIOCHEMICAL BLOOD PARAMETERS OF ROSS-308 BROILER CHICKENS WHEN INTRODUCING THE «KOVELOS-SORB» SORBENT INTO THE MAIN DIET

Abstract

Background. Currently, the poultry industry is developing quite intensively, this is why the use of various additives that accelerate growth and improve the quality of products is associated with this. The biologically active additive «Kovelos-Sorb» has similar properties – an enterosorbent based on particles of amorphous silicon dioxide.
 Purpose. To study the features of morphological adaptation of heart structures and biochemical blood parameters of Ross-308 broiler chickens when introducing the «Kovelos-Sorb» sorbent into the main diet.
 Materials and methods. Two groups of Ross-308 broiler chickens were studied from 1 day to 40 days, with a total number of 160 heads from 8 age groups of 10 individuals each. The experimental group of chickens was injected with the sorbent «Kovelos-Sorb» in the amount of 0.1% by weight of feed to the main diet. The study of morphological and biochemical parameters of the broiler organism was carried out according to generally accepted methods.
 Results. The analysis of the dynamics of changes in the morphological structures of the heart (linear measurements – longitudinal size, transverse size, girth, thickness of the epicardium, myocardium, endocardium, thickness of muscle fibers), the volume of cardiomyocyte nuclei, biochemical blood parameters of Ross-308 broiler chickens when added to the main diet of the enterosorbent «Kovelos-Sorb».
 Conclusion. It was found that the silicon-containing sorbent «Kovelos-Sorb» has a positive effect on the qualitative morphological characteristics of the heart of Ross-308 broiler chickens, manifested by stabilization of shell structures, in an increase in the thickness of the muscle fibers of the atria and ventricles of the heart.
