Comparative characteristics of the Ayrshire breed population size by constituent entities of the Russian Federation

Comparative characteristics of the population size of the Ayrshire cattle breed make it possible to determine the current state of the breed and the direction of its development in the constituent entities of the Russian Federation. The research was conducted on the basis of statistical data on the Russian Federation, districts, regions and republics using grouping, sampling, and comparing indicators in graphical and tabular versions. The relevance and novelty of the research consists in the fact that a comparative description of the modern livestock of the Ayrshire breed of cattle has been carried out in the Russian Federation, districts, regions and republics, making it possible to determine the numerical composition of the entire livestock and cows, taking into account the breeding status of the animals. The North-Western Federal District has been identified as the main breeding area of the Ayrshire cattle breed for all categories of farms, where 40.35 thousand heads or 57.9% are concentrated. In the Northwestern Federal District, 81.6% of Ayrshire breed animals are of pure-breeding strain, including 57.1% that belong to breeding farms. It has been established that the largest breeding population of Ayrshire breed animals is in the Northwestern Federal District in the Leningrad Region, the Republic of Karelia, and the Vologda Region. It has been found that there is the same number of animals in breeding farms (40.3%) and pedigree breeding units (36.8%) in the Central Federal District. The main number of Ayrshire breed animals in the Central Federal District is concentrated in the Tula, Moscow and Belgorod Regions. It has been established that in the Southern Federal District there is the largest breeding stock in the Krasnodar Territory and the Rostov Region. The Volga Federal District is represented mainly by the breeding stock of the Ayrshire breed of the Kirov and Samara Regions. It has been found that the lowest number of Ayrshire breed animals is in the Siberian and North Caucasian Federal Districts.
