The unresolved problem of quail is feed stress and high sensitivity of poultry of this species to feed quality. To eliminate such consequences it is possible with the use of various biologically active feed additives. However, their introduction into the diet automatically raises questions about the quality and safety of the products for the consumer. The purpose of the research is to conduct a veterinary and sanitary assessment of the quality of quail meat for feeding NDC. The purpose of the research is to conduct a veterinary and sanitary assessment of the quality of quail meat for feeding NDC. The object of study were the quails of the Pharaoh breed, at the age of 24 were divided into two groups: experimental and control 30 heads each. The birds were kept in cages with free access to food and water. Quails of the experimental group were added to drinking water feed additive "Nanocerium" at a dose of 8.6 mg per liter of drinking water. Nanocerium feed additive is an aqueous dispersion of NDC with average nanoparticle sizes of 2–7 nm. Antemortem examination of quails of both groups revealed a satisfactory clinical condition of birds. The average weight of the gut carcass of quails of the experimental group was higher by 8.3% compared to the control. Examination of 20 carcasses of quails showed that they can be classified as first class. According to organoleptic parameters, quail meat is of good quality in veterinary and sanitary terms. Microbiological studies of quail meat indicate no effect of NDC in the applied doses on its bacterial contamination. Chemical parameters of meat (pH, aminoammonia nitrogen, volatile fatty acids during storage in the refrigerator) (5 days, t = 4–5 ° C) tended to increase and were within the normal range for fresh product. Tissue in quails of both groups was not detected. The biological value of quail meat in both groups was identical and no toxicity. Tasting evaluation of the broth and meat showed that NDC did not affect the studied taste. The obtained results show that the quails that received the feed additive "Nanocerium" with water according to the indicators of veterinary and sanitary examination are of good quality, which allows to use it in human food without restrictions.

The territory of Ukraine is unique area in terms of iodine, which indicates the need for daily additional consumption of iodine along with the foodstuff. The major products applied for iodine deficiency prevention include salt and water optimized in terms of iodine and another microelements content. The thesis objective is to study influence of Iodis-Concentrate® preparation on rabbit meat quality parameters. Our aim was to find out the amino acid composition, the fatty-acid composition and mineral composition, as well as the iodine content in rabbit meat. There were two groups of two months old laboratory rabbits formed: the stud and control group (5 rabbits in each group). The rabbits of the control group were watered with the water taken from the well located in Obukhiv, Kyiv Oblast, while the rabbits of the study group were watered with the same water, although adding Iodis-Concentrate Preparation in the dosage of 0.35 mg/kg. In terms of organoleptic, physical and chemical indices, the rabbit meat corresponded to the fresh meat. The amino acid composition of the rabbit meat in the study and control group was slightly different. Subject to watering the rabbits with potable water with Iodis-Concentrate preparation added, the contents of certain indispensable and dispensable amino acids, and the aggregate contents thereof slightly increased, however, no trustworthy difference was recorded. No abnormal ratio of indispensable and dispensable amino acids was recorded. The biological value of the rabbit meat is preserved. As regards the fatty acids content, the meat of rabbits treated with Iodis- Concentrate preparation contained more fatty acids, as follows: lauric acid, myristic acid, Cys-10 heptadecenoic acid, elaidic acid, oleine acid, linolic acid, linolenic acid, Cys-11- eicosenic acid, Cys-8, 11,14- eicosatrienoic acid, Eicosatetraenoic acid, as compared to the control parameters, which indicates stimulation of lipid metabolism. During studying the influence of Iodis- Concentrate preparation on rabbit meat composition, the trustworthy high contents of the following microelements and microelements was ascertained: aluminum, calcium, chrome, ferrum, magnesium, manganese, natrium, strontium, and zinc. In the meat of rabbits treated with Iodis-Concentrate preparation, the researcher unveiled twice higher contents of iodine as compared to the performance in the control group of rabbits.

A study of the fish caught in the reservoirs of the Khadzhibey estuary (Odesa region) was conducted in order to determine its quality and safety according to microbiological indicators. No pathogenic or conditionally pathogenic microorganisms were found in all the fish samples studied – mirror carp (Cyprinus carpio) and round goby (Neogobius melanostomus). During the study of physico-chemical indicators of water quality and safety of the estuary, water samples were taken for the content of pesticides, insecticides and heavy metals. The content of cadmium, copper, lead and mercury does not exceed the permissible level for fish farms, zinc exceeds the maximum permissible concentration by 2.3 – 3.0 % (depending on the period of the year). The insecticide dichlorodiphenyltrichloromethylmethane was found in the water, the content of which exceeds the maximum allowable concentration for sea fishing ponds by 18 %, and the pesticide betahexochlorocyclohexane – by 5.2 %. It has been studied and established that the fish caught in the estuary, according to its microbiological and physicochemical indicators, is safe, does not pose a threat to the health of people and animals, and is suitable for further use and consumption.

Scientifically substantiated and experimentally proven the feasibility of conducting proper risk-based control of the safety and quality of freshwater fish in the Kyiv region's agro-food markets following the regulatory document's requirements, developed by express, improved methods for determining freshness and microstructural examination of muscle tissue. At organoleptic assessmentUkrainian scaly carp, crucian carp, and pike perch were fresh, and rotan was of dubious freshness. Regarding pH value, Nesler number, and qualitative reaction to the content of ammonia and ammonia salts with 'Nesler's reagent, the meat of Ukrainian scaly carp, crucian carp, and pike perch corresponded to fish of a fresh degree. For rotan meat, its dubious freshness was established. In the photometric determination of the studied fish's freshness, the optical density of the supernatant correlated with the quality indicators for the content of ammonia and ammonia salts. An improved benzidine test with a filtrate from the gills of the mouth confirms the doubtfulness of the freshness of the fish. The studied fish samples corresponded to the standard indicators according to microscopic indicators and the number of mesophilic aerobic and facultative anaerobic microorganisms. By determining the chemical parameters of the studied fish, it was found that the mass fraction of water in meat was the highest in rotan (78.30 ±0.13%) and was accompanied by the smallest mass fraction of dry matter (21.70 ±0.09), the proportion of proteins (16.96 ±0.06), indicators of fat in meat (3.01 ±0.06%) and formed the lowest indicator of its relative biological value - 92.5%. In benign fish with organoleptic indicators, a microstructural study of muscle tissue revealed significant changes in its structure with atrophy of individual muscle fibers and growth in these areas of connective, mainly fatty tissue.

In the modern conditions of dairy farming, the presence of indigestible foreign bodies in the stomachs of cattle is common, which is due to many factors. In 15 cows of the farm (6 % of the total number of animals in the herd), culled due to the pathology of the digestive organs, damage to the mesh and adjacent organs was diagnosed. The largest number of indigestible foreign bodies was metal objects, which were found in 8 cows; nylon ropes, kapron nets, polyethylene bags – for 4 cows; rags and leather items – from 2 cows; gravel and pieces of concrete were found in one animal. Consumption of indigestible foreign bodies is a common occurrence in farmed cattle, which can be a significant cause of loss of productivity, premature culling, and even animal death. Proper handling of indigestible foreign objects, plastic waste on the farm should be an integral part of preventive measures for animal disease, reduction of culling and improvement of animal welfare. Comprehensive dispensation must be carried out in the following areas: determination of herd syndromes, clinical studies of animals, laboratory studies of blood, milk, urine, analysis of feeding and keeping of animals. One of the main preventive measures is the regular probing of cows for metal-carrying objects with magnetic probes, the introduction of metal object catchers. Among the workers serving the livestock industry, carry out explanatory work on the danger of spreading various indigestible objects on the territory of fodder lands and livestock farms.
