Optimal feeding of sows is a complex problem due to their very different needs and use of nutrients during certain phases of the reproductive cycle. In pregnancy the sows need for nutrients is relatively small and slightly higher than maintenance requirements. In the last few years, the recommendations for feeding pregnant sows have been revised in such a way that greater protein (amino acid) and energy intake have been proposed for late gestation, compared to early gestation. The U.S. National Research Council (NRC, 2012) published the Nutrition models for swine, combined into a Microsoft Excel workbook and stored in the file NRC swine 2012. The program also includes a database with nutrient profiles of ingredients and a means to formulate diets and generate feeding programs. In the current paper, we will show agreements and differences between models and empirical data and discuss the implications and relevance for pregnant sow nutrition.
