VETERINARY AND SANITARY ASSESSMENT OF THE MEAT FROM ANIMALS AFTER ORAL ADMINISTRATION OF THE ANTIPARASITIC DRUG «DEGELM-16»

Abstract

The paper presents veterinary and sanitary assessment of the meat from rabbits and pigs, who had taken a new anthelmintic drug «Degelm-16» in their diet. The meat from 6 rabbits and 6 gilts who were divided into experimental and control groups was studied, three samples per each group. The drug «Degelm-16» was given alimentary with foodstuff to the animals of the experimental group 5 days before the slaughter at a dose of 50 mg/kg. Rabbits and gilts of the control group did not receive the drug. It was discovered that meat samples taken in the control and experimental groups of rabbits and gilts contained a drying crust, elastic muscle fibers. The characteristic smell of test samples corresponded to the specimens species. Meat samples from both animal species were of pale pink colour. Boiling of the meat from rabbits and gilts resulted in cloudy-white broth with pleasant specific smell. The benzidine reaction revealed a peroxidase positive result in the meat extract. The amount of amino-ammonia nitrogen in both rabbit groups ranged from 0.54 to 0.60 mg, in gilt groups – from 0.76 to 0.79. The volume of volatile fatty acids in rabbit meat samples ranged from 1.82 to 1.89 mg KOH. In gilt meat – from 2.19 to 2.43 mg KOH of volatile fatty acids. The reaction for the protein primary decomposition products using copper sulphate in both groups resulted in getting the broth without clots and flakes confirming appropriateness of the meat. The touch smears bacterioscopy showed presence of single microorganisms in the surface layers and complete absence of the bacteria in the deep layers. The data of microbiological analysis did not reveal deviations from the reference values.
