Defence of work of research on PCV2

Next Thursday, 29th October 2009, Sergio López Soria, researcher of the CReSA, will defend his work of research entitled “Lack of transmission of porcine circovirus type 2 to weanling pigs by feeding them spray-dried porcine plasma” directed by Dr Joaquim Segalés.

Spray-dried porcine plasma (SDPP) is an animal by product widely used in diets for weanling pigs to improve their growth and feed efficiency. SDPP is obtained from porcine blood at slaughterhouse and its manufacture has several safety steps that would be expected to have at least a partial neutralising effect on potential pathogens.

The present study was conducted to determine whether SDPP, containing porcine circovirus type 2 (PCV-2) genome, could infect weanling pigs when fed to them. For a higher probability of PCV-2 infection, SDPP was provided in more than twice the usual amount in commercial diets, and the SDPP batch used was that with the largest number of PCV-2 DNA copies among five different batches. After 45 days of consumption of a diet with 8% SDPP, none of the pigs developed any clinical signs or became PCV-2 viraemic or seroconverted.

This study was published at The Veterinary Record as “Lack of transmission of porcine circovirus type 2 to weanling pigs by feeding them spray-dried porcine plasma.  Pujols J, López-Soria S, Segalés J, Fort M, Sibila M, Rosell R, Solanes D, Russell L, Campbell J, Crenshaw J, Weaver E, Polo J. Vet Rec. 2008 Nov 1;163(18):536-8”.

The event will be hold next Thursday, 29th October 2009, Seminari 11 (V1-201) of the Veterinary School of the Universitat Autònoma de Barcelona, at 11:00 h.
