Influence preservatives on the histopathological picture of some internal organs of minks
The study was conducted at the “"scanbrown"” mink breeding farm. After weaning, the animals were divided into two groups, 50 units each (I treatment, II control). Both groups were fed a diet having an identical composition and energy level, but group I received a dietary preservative and antioxidant additives. Sodium pyrosulphite was added at a dose of 0.2-0.3% ready feed mass and Hadox antioxidant at a dose of 0.15-0.20 g per 1 kg ready feed until November. The slaughtered animals (10 units from each group) were subjected to postmortem and pathomorphological examinations. Histopathological examinations were carried out on sample specimens of the internal organs essential to the digestive and absorption processes and metabolism (stomach and duodenum, small intestine, large intestine, liver, kidneys).The feed preserved with sodium pyrosulphite and Hadox antioxidant did not show microbiological contamination at a level which would be hazardous to animal health. Supplementing the feed with a preservative and antioxidant resulted in a variation within the histopathological changes in the liver of both groups of animals. The kidneys were reported to show slight epithelium steatosis of the I order and convoluted tubules. No pathological changes were recorded in the images of the mink'’s alimentary tract.
