WOOL AND SHEEPSKIN-CHEESE PRODUCTIVITY OF SHEEP OF DIFFERENT ETHOLOGICAL TYPES OF BEHAVIOR

Abstract

It is now well known that the wool productivity of sheep depends on hereditary, feed and environmental factors. The interaction of the animal organism with paratypic factors occurs under the direct control of the nervous system, therefore the level of productivity of sheep, including wool, depends on the type of nervous activity, i.e. animal behavior.
Wool is of great economic importance as a raw material for light industry. Despite the rapid development of the production of synthetic fibers used in the textile industry, the need for natural wool does not decrease.
In this regard, of particular interest is the study of wool productivity and wool quality, depending on the ethological characteristics that we obtained from the Romanivka meat-wool breed of sheep.
Therefore, the aim of the work was to study the wool productivity of meat-wool breeds of sheep of different ethological types of behavior and their welfare and well-being. 
The research was conducted using modern general zootechnical research methods, namely: experimental, analytical and statistical.
As a result of our research in the field of sheep breeding, the conditions of keeping sheep are significantly changing, individual care for animals is sharply reduced and modern technologies are used to a large extent.
Under these conditions, stress factors arise that cause stress to the nervous system of animals or even their death.
As a result of research, wool productivity, being a hereditary trait, largely depends on the conditions of feeding, housing and biological characteristics of the nervous system of sheep. At the same time, the age of raising animals has a significant impact on the formation of wool products.
Therefore, for the full formation of sheep wool production, the type of sheep behavior and the duration of their rearing should be taken into account.
Thus, animal behavior, like other economically useful traits, is under the constant influence of evolutionary processes.
In this case, animals acquire high plasticity of adaptation to changes in existence; first, behavior changes under the influence of the external environment, and then the entire organism is restructured.
