Porcine Health Management

Sows’ mass vaccination (SMV) with modified live virus vaccines (MLVv) is a very common strategy in order to control and prevent porcine reproductive and respiratory syndrome (PRRS) in breeding herds. Despite the safety of MLVv which have been widely...

Vaccinating sows with modified live PRRS virus vaccines (MLV) may result in transient shedding of the vaccine’s virus, which has the potential to be transmitted to their offspring. Therefore, sow mass vaccination (SMV) programs may affect PRRS status of...

Oral live E. coli vaccines against PWD can be administered to pigs from 18 days of age. These vaccines are made up into suspension with water to be orally administered and should be consumed within 4 hours. Administration of the vaccine with bowls is...

The study was conducted to evaluate the protective efficacy of type 1 porcine reproductive and respiratory syndrome virus (PRRSV) modified live vaccine (MLV) when administered intramuscularly (IM) or intradermally (ID) in pigs against either a single...

PRRS (Porcine Reproductive and Respiratory Syndrome) is probably the most costly pig disease in The Netherlands and farmers are increasingly vaccinating piglets with MLV (modified-live-virus) PRRS vaccines. The objective was to assess the presence of PRRS...

Edema disease (ED) is an enterotoxaemia caused by the Verotoxin 2e (Vt2e) of E. coli. The subclinical form of the disease is characterized by a delayed growth performance without clinical signs. Detection of the vt2e gene in piglets allows the...

The aim of this study was to assess and compare the humoral immune response and safety effects after vaccination against Swine Erysipelas (SE) and Porcine Parvovirus (PPV), using two commercial bivalent vaccines under field conditions.

The future ban on using antimicrobials and heavy metals as prophylactic measures pushes to find new approaches to maintain the gut health of piglets. By understanding how alternatives work, new feeding strategies could be developed. The main objective of...

High levels of maternally derived antibodies (MDA) partly interfere with the induction of humoral immunity elicited by vaccination against Porcine circovirus 2 (PCV-2). Within this scenario, there is controversy about its interference on vaccine efficacy...

Spanish piglets are usually vaccinated against PCV-2 and Mycoplasma hyopneumoniae (M.hyo). The market offers different possibilities. This field study compares two different protocols; one using separate vaccinations with monovalent PCV-2 and M.hyo...

PCV2 and Mycoplasma hyopneumoniae are two of the most frequent pathogen of swine causing major economic losses. The efficient prevention requires a long lasting protection, which can be evaluated by scoring lungs at slaughter and by recording pigs’...

Vaccination against PRRSV still remains unsatisfactory regarding efficacy and safety. In this study, we tested the in-vitro antigenicity and safety of highly pathogenic (HP) Porcine Reproductive and Respiratory Syndrom Virus (PRRSV) 2 irradiated in two...

A single herd can suffer a variety of diseases caused by different pathogens. To reduce the number of injections, and therefore the stress on the sows, it is preferable to use combined vaccinations against more than one agent. The aim of the present...

The objective of this trial was to evaluate the efficacy of piglet’s vaccination to reduce the clinical signs and mortality related to H,parasuis in finishing pigs.

A new octavalent vaccine, Porcilis® Ery+Parvo+Lepto (MSD AH) was recently launched in Europe. The aim of this trial was to evaluate the safety of the vaccine in a commercial sow’s farm.
