PRRSV can cause significant impact on reproductive performance in endemically infected herds. This study aimed to investigate sow performance before and after implementation of a sow herd vaccination against PRRSV on a farm in Serbia.
Cough is a common symptom of finishers. Nowadays, real-time technology is available for pig cough recognition as part of a precision livestock farming system1,2. However, once cough is recognized in the field, there is a need for a better understanding of its concurrent impact on growth performance. Therefore, the objective of this study was to compare and quantify the impact in daily growth (ADGW) of disease-coughing outbreaks occurring in a finishing batch of pigs under commercial conditions.
Current swine production systems are achieving remarkably high numbers in piglets/wean/sow per year. This high performance of the sow during the lactation period is potentially due to genetic, feed, health, and management improvements. However, despite these important efforts, post-farrowing vaccination in sows is routinely applied to protect the breeding stock against Parvovirus sp. and erysipelas1.Therefore, there is a need to study the impact that this strategy may have on sow and piglet’s production performance parameters when applied during their lactation period2,3. As a result, the objectives of this study were to evaluate the potential impact that vaccination during the lactation period may have in sows and their offspring’s performance.
Porcine circovirus type 2 (PCV2) has a great impact on breeding herds, predominantly associated with increased stillborn and mummified fetuses at parturition. (1, 2) Reports have shown that mass vaccination of sows against PCV2 would improve the reproductive performance and are proven to be safe. This study reports a recurrence of PCV2 infection in the sow herd after discontinuation of mass vaccination against PCV2.
