At attempt was made in the paper to calculate the unit costs of piglet production depending on the number of litters and piglets per sow in a year. The unit costs of piglet production up to 300 kg of body weight depended on the production and economic results obtained in individual pigsties. The lowest costs per production unit were achieved in pigsty where 2.2 liters and 20 piglets per sow were obtained in a year
