Sheep farming plays an important role in the production of meat. Romanov
breed is known for its high fertility and therefore is used all over the
world due to increased production of lambs and lamb meat. Meat products are
the main food elements of the man. Most of the inhabitants of industrialized
countries cannot imagine their menu without meat. Value of meat for human
health is known, it supplies protein to the body. The Yaroslavl Region is a
leading region of the Romanov sheep breed. Therefore, the aim of our
research was to determine the strength and reliability of the influence of
the factor «genetic value of the father» on productive characteristics of
animals as a factor that helps to increase the productivity of animals. Upon
determining the strength of the influence of factors for statistical data
have used the procedure of generalized linear models (General Linear Models
- GLM), and evaluation components of phenotypic variation attributes were
analyzed by multivariate dispersive analysis. Our research has allowed
allocating rams with genetic value that has the improving effect. Using the
recommended lines the farmers of the Yaroslavl region may increase
productive characteristics of animals and the profit of the farms and
improve the efficiency of breeding.
