The meat processing industry in Slovenia had show interest in rearing heavier pigs in the last fey years. This caused a lot of questions including that about the economics of such a rearing. The purpose of project is to estimate and highlight some facts in the economics of fattening heavier pigs. The estimation of the economics was made using a simulation model developed at Agricultural Institute of Slovenia, which enables the estimation of total production costs. As the initial value, the calculation of fattening pigs until 100 kg of live weight and 800 g/day of daily gain used. This calculation was completed and adjusted to fattening pigs for higher slaughter weight (130 kg). Two other models were made beside the original one. The first one considered the technological parameters of rearing heavier pigs from foreign literature, while the second one was only an extension of rearing pigs considering the parameters from one of Slovenian research projects. The fattening of heavier pigs results in the lower total costs per year, but, considering a lower number of annual realization, it also causes a lower income. If pig needs are considered and the feeding method is adjusted to them (especially the number of feeding periods and the content of energy and proteins in feeds), this has a significant influence on the decrease of costs. Fattening pigs above 100 kg live weight causes a decrease in the percentage of meat in carcasses, which means a lower selling price and a lower income. The total costs per kg of meat are 10 % higher at fattening heavier pigs. In comparison with the usual practice, breeders of heavier pigs have to achieve higher selling prices if they want to reach the same profit.
