Compound and yeast hydrolysate composition for replacing spray dried plasma protein, as well as preparation methods and applications thereof

The invention provides a compound and a yeast hydrolysate composition for replacing spray dried plasma protein, as well as preparation methods and applications thereof. The compound comprises the following components in parts by weight: 100-250 parts of glutamine, 5-20 parts of butyric acid, and 2-5 parts of ethyl maltol. The yeast hydrolysate composition comprises the compound and a yeast hydrolysate. The compound containing glutamine, butyric acid and ethyl maltol is added into the yeast hydrolysate, in order to obtain the yeast hydrolysate composition. The yeast hydrolysate composition cancompletely replace spray dried plasma protein with bio-safety hidden trouble; compared with effects by using spray dried plasma protein, pigling ingestion characteristics, immunization performance andgrowth speed are equivalent or improved, and the products have wide application prospects. 本发明提供种替代血浆蛋白粉的复合物、酵母水解物组合物及制法和应用。该复合物包括谷氨酰胺100-250重量份，丁酸5-20重量份以及乙基麦芽酚2-5重量份。该酵母水解物组合物包括上述复合物和酵母水解物。在酵母水解物中添加包含谷氨酰胺、丁酸和乙基麦芽酚的复合物，得到酵母水
