In 2009, an increase in the number of pigs and sows was detected. The number of sows is considered to be particularly important because it forms the basis of pig production. In 2009. , the number of sows increased by 4% compared to the previous year, which is the largest increase in the observed period. PIC and Topigs hybrids are most often kept on large headlights. The advantages of breeding hybrids are multiple: the animals are identical, and this is especially important on the slaughter line, because the halves are the same weight, cut certain pieces of meat weigh the same and look the same, and sorting and packaging meat in large production is faster and easier. Noble breeds and old indigenous breeds are still kept on small farms and family farms for the sake of tradition. These breeds are not highly productive as they produce fewer piglets per litter than hybrid breeds. Regardless of the representation of individual breeds in breeding, the efficiency of pig breeding in Croatia is still lower than in some European countries. One sow in Croatia releases an average of 27 piglets per year, while in more developed pig farms in Europe the number is 32 piglets per sow per year. The autochthonous breed of Black Slavonian pig has gained high popularity on small farms and large farms over a period of ten years. This breed has a higher fat content than the hybrid breed, but has very tasty meat, which makes it interesting as a product. The disadvantage of its cultivation is the slow and long production, and the advantage is the recognizability of the product quality. In the time period from 2008 to 2019, the fertility of sows on large farms recorded a positive trend, which means that certain breeds and hybrids in the selection program increased the number of pollinated piglets per litter. In 2008, an average of 11 piglets were pollinated per litter, and in 2019 that number increased by 36% and averaged 15 piglets. In the observed period, the number of heads delivered for fattening increased by 14.3% and the number of heads delivered for slaughter increased by 22.6%. The duration of fattening in days decreased 50 50 by about 12% (from 120.2 days to 106 days), daily gain increased by 32%, average weight of halves by 14.7%, and the share of meat in halves by 16.4%. A significant difference in the number of litters per sow per year was observed between large farms (about 2.3 litters) and family farms (about 1.5 litters). In the chapter that explained import and export of pigs, pork, meat products and fats, it is clear that imports in the Republic of Croatia are higher than exports. The self-sufficiency of the Republic of Croatia in pork production increased from 33% in 2016 to 49% in 2019.
