Variation of a ratio of yelts and gilts in a nest has a significant effect on economic indicators. A positive effect can be achieved if gilts prevail in nests. It is explained by a steady dependence between a ratio of gilts and yelts at birth and the need for sows for production of a specified number of piglets of a defined sex.
