Abstract

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.

Highlights

Scrapie of the sheep - a contagious slowly developing disease of small cattle, characterized by itching with subsequent scratching, nervous manifestations another name for the disease is "pruritus"
The importance of TSEs lies in the zoonotic characteristic of strains that affect cattle (BSE), This represents a problem both economically and for public health
The absence of a specific epidemiological picture and various strains of the pathogen play an important role in interpopulation variability

Summary

Introduction

Scrapie of the sheep - a contagious (infectious) slowly developing disease of small cattle, characterized by itching with subsequent scratching, nervous manifestations another name for the disease is "pruritus". Since the middle of the last century, the efforts of veterinary specialists have been aimed at studying the pruritus of sheep, identifying the pathogen, transmission mechanism, finding methods of treatment and prevention. Immunohistochemistry (IHC), which is the standard method for detecting scrapes in goats, can detect prions in CNS tissues or in lymph nodes. In other species, such as cattle or sheep, other diagnostic tests, such as the Western blot or the ELISA test, these tests were not widely used in goats [5]
