Abstract
On the territory of Ukraine, for decades, the pig industry has traditionally remained one of the main reserves for ensuring the financial well-being of the population. Among the factors contributing to the profitability of pig breeding enterprises, a significant role is played by the breeding capacity of sows, since it guarantees the receipt of livestock for rearing and fattening. An indisputable condition for ensuring the efficiency of pig production is to increase the fattening and meat characteristics of pigs. With this in mind, the purpose of the study is to investigate the abovementioned economic traits of pigs, which is currently an urgent task. The research was preceded by the establishment of three groups of sows and young stock, numbering 10 animal units each, located in similar economic conditions. According to the investigational plan, three groups of pigs are provided depending on the genotype: control group 1 – Large White (LW); experimental group 2 – Landrace (L); experimental group 3 – 1/2LWx1/2L (maternal base – Large White, paternal – Landrace). As a result of the conducted studies, it was found out that the local pig population obtained from crossing purebred animals of the Large White and Landrace breeds prevailed in terms of productivity over the original parent forms. From them, on average for three farrowing operations, the largest number of piglets at birth and the highest multiplicity were obtained. An unreliable correlation was found between the characteristics of the reproductive ability of sows and the number of farrowing. The correlation coefficient between the farrowing number and the number of piglets at birth had a negative value – -0.013; for fertility – positive – +0.038; for the offspring size – +0.014; milking capacity – +0.044. At the age of 1, 2, 3, 5, and 6 months, local young stock had the highest live weight, and the Large White pigs had the lowest values with significant differences (P≤0.05-0.001). The Landrace pigs had the highest live weight at birth and at the age of 4 months, and the Large White pigs had the lowest live weight (P≤0.05-0.001). The findings allow increasing the efficiency of the pig industry and prove the expediency of interbreeding in order to increase the economic traits of pigs
Highlights
The ability of the state to provide the population with high-quality food products is guaranteed by the availability of appropriate resources, among which the pig industry covers the demand for meat consumption by 35%

Summary
The ability of the state to provide the population with high-quality food products is guaranteed by the availability of appropriate resources, among which the pig industry covers the demand for meat consumption by 35%. The market situation forces pig breeding enterprises to look for ways to reduce the cost of production and improve its quality [4]. Today, the development of pig breeding, as an industry with a large production potential, is marked by an in-depth use of available resources and provides for the introduction of well-organized breeding work [5]. 12 stud pig breeds are bred at farms of Ukraine, which serve as maternal and paternal forms in breeding and can improve the pork production indicators [6]
