    The profit equation method was used in order to derive economic weights on a hypothetical Hungarian Large White pig population. The size of the population was held constant at the number of 100 sows ... which constructed four equal age categories (12, 18, 24, 30 months of age). Average farrowing interval was supposed to be 6 months, all of the sows were fertilised each year. Conception rate and weaning rate was 85% and 90%, respectively. The average litter size was set to be 10 thus total number of the weaned piglets per year was 1530. After replacement 25 culled sows and 1505 pigs could be sold in every year. Economic weight for number of piglets born was 1.1 EURO. Comparing the economic weight of the born piglet with that of the unit of product it can be concluded that reproductive performance receives strong emphasis in Hungary.
