This study aimed to determine the porcine circovirus type 2 (PCV2) serological and virological dynamics in piglets vaccinated at different ages a PCV2 subclinical infection (PCV2-SI) scenario. Six hundred forty-four week-old healthy were selected distributed into four treatment groups: vaccination 3, 6 or 10 weeks of age (3W-VAC, 6W-VAC 10W-VAC groups, respectively) unvaccinated pigs (NON-VAC group). Blood (n = 112 pigs) oral fluid (OF) 40 pens) samples taken throughout assess load, humoral...
This study sought to evaluate the effect of sow vaccination against Porcine circovirus 2 (PCV2) on reproductive parameters during two consecutive cycles. The was performed in a PCV2 subclinical infected breeding herd (PCV2 circulation but absence major problems). Ninety-four pregnant sows were primo-immunized with commercial vaccine and ninety-seven injected phosphate-buffered saline at 6 3 weeks before first studied farrowing, then boosted second one. Blood samples taken throughout assess...
The present work describes the serum haptoglobin (Hp) dynamics in piglets vaccinated and non-vaccinated with a commercial porcine circovirus type 2 (PCV2) vaccine at 3 weeks of age, its relationship average daily weight gain (ADWG). field study was carried out on two farms (A B) previous clinical history PCV2-systemic disease (PCV2-SD). aim to assess whether Hp could be used as surrogate marker PCV2 efficacy. infection confirmed by quantitative real time PCR (qPCR) pigs from both farms, but...
