Assessment of regeneration of the bronchial ciliated epithelium with an increase in vitamin A content in the diet turkey

Abstract

The study was aimed at studying the relationship between the concentration of vitamin A in the turkey diet and the change in the amount of ciliated epithelium in the bronchi. Methods and methodology: to increase the dosage of vitamin A, the “Alphabet AD3E” multivitamin complex was used in the experimental group for 10 days with the slaughter of poultry on days 3, 5 and 10 of the study with the study of macro and microcartins of the epithelium with the counting of ciliated epithelium cells per 1000 cells in each bird. Subsequently, the concentration of cells of the ciliated epithelium was analyzed in the experimental and control groups. The results of the study demonstrated not only an increase in the number of cells of the ciliated epithelium in the experimental group compared to the control group by 27.3% at the end of the experiment, but also allowed us to note a greater speed of processes during the recovery period after the respiratory disease of the turkey. The scientific novelty lies in the study of the relationship between the concentration of vitamins in the diet of poultry and the quantitative change in the epithelium of the respiratory system of poultry, which in turn is necessary for a broader understanding of the causes and spread of diseases of the respiratory tract.
