U.S. research suggests that porcine SDP could represent a biosecurity risk for the pork industry and, as a result, bears further scrutiny
by JANICE MURPHY
Incorporating spray-dried plasma (SDP) into the diet of weaned pigs has been proven to increase feed intake and growth performance. However, limited research has been carried out to confirm that the spray-drying process eliminates viral contaminants, such as porcine circovirus type 2 (PCV2). Fear of spreading the virus has resulted in some producers removing plasma proteins from their rations completely.
