Saccharomyces cerevisiae yeast (SCY) is commonly used as an additive in feed (<1% of the formulation), but there is a limited amount of available information about its function as a promising source of proteins for pig diets, and especially, the nutritive value of yeast protein for gestating sows remains to be clarified. Feeding stuff has different digestibility between growing and gestating pigs. Therefore, our study evaluated the standardized ileal digestibility of amino acids and crude protein together with metabolizable and digestible energy in SCY for gestating sows, to provide nutritional value parameters on its potential as an effective alternative to traditional protein ingredients such as soybean meal in sow diet formulations.
