An experiment was conducted to determine whether spray‐dried porcine plasma containing 2·47 × 10 5 dna copies of porcine circovirus type 2 ( pcv‐2 ) could infect weanling pigs when fed to them. Five specific pathogen‐free ( spf ) weanling pigs were fed ad libitum for 45 days a control diet and six pigs were fed a test diet containing 8 kg sdpp per 100 kg feed. The two groups were housed in separate biosecurity level‐3 rooms. None of the pigs in either group developed any clinical signs or became pcv‐2 viraemic or seroconverted.
