A study performed by Darling Ingredients tested pig blood plasma as a replacement of fishmeal in shrimp. Researchers found an average of 1 gram weighed higher on shrimps fed on plasma diets and higher levels of IgT antibodies in the intestinal villi.
The company collects plasma mostly from pig’s blood, separating the red blood cells and spray-drying the plasma to avoid damage on active proteins. It is still a relatively expensive protein to produce, but the company suggests using it in combination with other protein sources.
“We are getting experience in this field and we are also looking for ways to do more research in aquaculture,” said Lourens Heres.
