PIGS OF MEAT BREEDS IN UKRAINE AND THE NEED FOR THE REVIVAL OF PIG BREEDING

Abstract

The article highlights the peculiarities of pork production in Ukraine, examines the productivity of domestic and foreign meat breeds of pigs in the dynamics of 2002–2022. It was found that the meat pork market in Ukraine developed intensively from 2002 to 2016, with a sharp reduction thereafter. The breeds of pigs in the meat direction of productivity include Durok, Landras, Pietrain, Poltavian Meat, Welsh, Ukrainian Meat and Red White-Beltid with some changes in the breed composition during 2002–2022. It was established that until 2005, the leaders in the meat pork production market were the Ukrainian and Poltavian Meat breeds, which were later supplanted by Landrace pigs. The population of the main sows of the investigated breeds was 7.8–9.3% of the total number of pigs, including 8.9% in 2022, which ensured the necessary reproduction of animals with some nuances regarding small populations. In 2022, the number of queens of the landrace breed will be 87.7–98.8% higher than the number of the rest of the studied breeds. Sows of meat breeds, which were bred in breeding farms during 2002–2022, are characterized by significant variability of multifertility, and the difference in the trait within one breed quite often exceeded the interbreed difference. The variability of the best indicators of the age of pigs reaching a live weight of 100 kg in the process of their cultivation in representatives of the Durok breed during the years 2002–2022 was 164–178 days, Landras 148–183 days, Pietrain 150–154 days, Poltavian Meat 179–198 days, Welsh 156–187 days, Ukrainian Meat 174–187 days and Red White-Beltid 181–207 days. The highest indicators of average daily gains were among pigs of the Durok breed, which varied between 658–810 g, Landras 612–860 g, Pietrain 520–890 g, Poltavian Meat 574–735 g, Welsh 344–628 g, Ukrainian butchers 435–768 g and Red White-Beltid 470–635 g. It has been proven that Durok pigs in the best breeding herds had lard thickness at the level of 13–16 mm, Landras 10–12 mm, Pietrain 7–9 mm, Poltavian Meat 21–23 mm, Welsh 12–16 mm, Ukrainian Meat 16–20 mm and Red White-Beltid 22–23 mm. On the example of the genealogical structure of pigs of the Landrace and Pietrain breeds, as well as the market for the sale of breeding offspring and semen, the conduct of purebred breeding in subjects of the breeding business in the pig industry of Ukraine is questioned. In order to revive Ukrainian pig farming and bring order to breeding pig breeding, it is recommended to take into account the requirements for the functioning of the pig breeding industry in the countries of the European Union.
