The SPC is distinctly different to the soybean meal ; thus it contains just traces of oligosaccharides and the antigenic substances glycinin and β-conglycinin. Therefore it can be used in milk replacer feed for non-ruminant calves, piglet pre-starter feed, pet food, feed for fur bearing animals and in aquaculture. In milk replacer feed, SPC substitutes dried skim milk to a large extent. In pig starter feeds it also can replace dried skim milk, whey powder and fishmeal. The nutritional value is only slightly below that of dried skim milk. The negative influence of dietary soybean meal on the intestinal tract lining of pigs and on the serum antibody titer is not observed when SPC is used. Whereas in feeds for young mammals the use of SPC has been established for many years, in aquatic diets it is still at the beginning. The focus of nutritional research today is to evaluate the possibilities of replacement of fishmeal in diets for salmon and trout. Also the fast growing shrimp industry is investigating the use of SPC in their shrimp diets. However, the dietary amino acid pattern has to be balanced according to the species specific amino acid requirements. Due to the fact, that methionine plus cystine are the limiting amino acids in soy protein, DL-methionine should be added to the diets when necessary.
