Dear Ward Peeters. Thank you for visiting the KOSIS website. ○ As you see, the net profit of hogs recorded 82,000 won per head in 2016. The net profit per hog is calculated as the difference between gross receipts and the cost incurred in the process of purchasing / acquiring a baby hog and selling it after a certain period of time. And according to Livestock Statistics in the third quarter 2017, on average, 2,372 pigs are raised by a hog-breeding household. ※ Net profit per hog = Gross receipts – Breeding cost - Gross receipts: Total amounts of receipts of main products by selling a hog after breeding it for a certain period of time and receipts of by-products - Breeding cost: Total cost value of goods and services consumed when breeding a hog Thank you.
