In this paper, we consider the control of animal carcasses and the detection of such a disease as scrapie. For our country, this animal disease remains quite rare, but at the same time it should not be overlooked. This is due to the fact that there are regular purchases of breeding cattle from abroad, and this is a risk of importing an infected animal. The relevance of the work is that the disease of sheep and goats-scrapie can not be detected at very early stages of its development. Symptomatic manifestations do not appear immediately, there are no clear clinical characteristics, which is why this disease can not be diagnosed for a long time. To assess the health status and predict the quality of products obtained, new approaches are needed to study the products of sheep and goat slaughter. Great importance is given to standard methods of studying, identifying certain patterns in clinical, anamnestic, morphological, metric and anatomical indicators of the animal body. Using these indicators and changing their dynamic characteristics, it is possible to make significant adjustments in the definition of this disease, which would allow us to develop a number of rules for modern veterinary and sanitary evaluation of animal slaughter products.
We have developed an ointment preparation consisting of silver and zinc oxide nanoparticles, which form the basis of the nanocomposition. This drug can reduce the healing time of the wound surface due to the inclusion of nanodispersed particles in the composition. Application of nanoparticles allows to reduce inflammatory process, to carry out disinfecting treatment of a wound surface from pathogenic microorganisms, and accordingly to create optimum conditions for reparative process. Nanocomposite preparation has many advantages over existing analogues without irritating and allergic effects. Due to the high adsorption capacity, it allows to accelerate the healing process of the damaged surface of the skin. Initial studies were conducted on laboratory rats at the age of 6 months with a close mass that was up to 250 g in accordance with international requirements for the use of laboratory animals. As a result of the experiment, a new ointment preparation based on silver and zinc oxide nanoparticles, which are active components of the nanocomposition, was obtained. The use of these components allowed to accelerate the process of reparative restoration of the skin with full recovery of the studied animals. As shown by the experience, the recovery rate on average accelerated by seven days, compared with similar drugs available on the pharmaceutical market.
This paper discusses the use of feed additives with the addition of amino acids containing methionine and cysteine. To study the effectiveness of the use of feed additives, one of the main functional systems of the body of any animal, blood, was monitored. In confirmation, blood samples were taken for hematological and biochemical examination. It is shown that in the first months of use there is an increase in the weight of ducks, and in the period of egg production there is a decrease in productivity. Reduced productivity is associated with the preparation and restructuring of the body for egg production. New approaches to the development of feed additives are needed to assess the state of health and predict the quality of products. Great importance is given to standard methods of studying and identifying certain patterns in the clinical, anamnestic, morphological, metric and anatomical parameters of the bird body.
The intensity and direction of the living organism’s metabolic processes determine the growth rate, development, nutrients synthesis, as well as the reproductive body function and the biosynthesis of proteins, fats and carbohydrates in the form of feedstuff and raw materials. The higher animals’ productivity, the more intensive are metabolic processes. The living bodies’ metabolism proceeds with a certain speed and at the same time contrariwise, but with accurate coherence and interaction due to the participation of “life regulators”, enzymes, which represent the specific proteins, the activity of which is regulated by hormones, vitamins and various synergistic elements. Chemical elements included in the living organism structure are not synthesized in it but must be originated from feeds and other nutrients. Changes in essential micronutrients supply shall not be studied in isolation from the general bio-geochemical situation. Both excess and deficiency may lead to metabolic disorders involving enzyme systems. Knowledge applied by veterinary specialists about the imbalance of various chemical elements in soil, water and feeds has formed the basis for raising the issue of endemic animal diseases diagnosis and prevention. The feeds inadequacy often leads to undernutrition and the reduction of their value in the stall period, which causes the fatness reduction and, therefore, the decrease in mobility and activity, and the weakness of animals. General inspection and palpation of animals reveal ruffled coat, dry-looking and non-supple skin, and if the lack of nutrients becomes more intense, anemic mucous membranes (in more complicated forms even cyanosis and icterus) are observed.
The work is devoted to assessing the quality of livestock slaughter products, taking into account skin diseases of various etiologies. This criterion sometimes makes a significant contribution to the quality of livestock products, so it must be taken into account during veterinary and sanitary examination in laboratories. To assess the state of health and predict changes in the quality of products of the slaughter of sheep, great importance belongs to the study of patterns in the clinical, anamnestic, morphological, metric, and anatomical indicators of the body of the sheep. The use of these patterns and their dynamic changes characteristics helps to find out certain patterns that made it possible to develop several rules for the modern veterinary and sanitary assessment of sheep slaughter products. These rules allow not only to indicate the premisses for the occurrence of dermatitis of various etiologies but also to improve existing developments, as well as improve the quality of preventive remedies to prevent and eliminate these types of diseases. It should also be noted that for the start of preventive steps, the strict observance of elementary rules is important when grazing the number of sheep. This includes their movement in compliance with certain periods, the seasonality of the use of forage land, and the mandatory inspection of the livestock of animals and their parking places. In the case of the detection of infected animals with signs of damage to the skin, the animals are immediately isolated with subsequent diagnosis and treatment.
