Histomorphological parameters of quail liver when using a feed additive with L-carnitine in the diet

The article presents data on the effect of the feed additive “FITODOK® Carnitine” (manufacturer – OOO «AVZ FARM», Moscow) on the histomorphological indices of quail liver. The experimental part of the work was carried out at the Department of Parasitology and Veterinary-Sanitary Expertise of the Federal State Budgetary Educational Institution of Higher Education Moscow State Academy of Veterinary Medicine and Biotechnology – Moscow Veterinary Academy named after K. I. Skryabin. Clinically healthy Texas quails were used in the experiment. Use of the feed additive “FITODOK® Carnitine” in the diet of animals and birds. Analysis of the conducted studies showed that the quail liver exhibits a pathohistological picture indicating the development of parenchymatous fatty degeneration of hepatocytes. Pronounced large- and medium-droplet fatty degeneration of hepatocytes was found in the birds of the control group, while in the first experimental group of birds fatty degeneration was predominantly medium-droplet, and in the second experimental group – weakly expressed small-droplet.
