REGIONAL CHANGES IN THE PIG POPULATION IN POLAND IN 2010-2022

The aim of the study was to assess regional changes in pig and sow population in 2010-2022. The analysis was carried out at the voivodship level for the entire period under study, while changes in pig and sow population in poviats were based on agricultural census data for 2010 and 2020. The analysis showed a progressive regional concentration of pig and sow stock in Poland, as indicated by an increase in the share of the 62 and 93 poviats with the highest stock and the poviats with the highest density of pigs and sows using 20% and 30% of agricultural land in Poland by about 9 percentage points. However, there was no correlation of the level of pig and sow stocking in 2010 in individual poviats with changes in stocking rates by 2020. A large increase in stocking rates associated with the construction of industrial piggeries was recorded in a dozen poviats located mainly in the western and northern voivodships, where the largest number of State Agricultural Farms were located.
