Swine vaccines
Vaccinations are available for a number of diseases that affect swine. In some cases vaccination constitutes the major part of the control of the disease. In many other cases it is only a small part of the control program. Vaccination programs need to be tailored to each swine operation. Remember that vaccination only raises a pig's level of resistance. If other important management procedures are neglected, even this elevated level of resistance may be inadequate to prevent disease.
Vaccines must be stored and administered according to label directions if they are to be effective. Slaughter withdrawal time must be observed at all times to avoid illegal residues. The most common times for administering many vaccines are before breeding and before farrowing. This protects the sow and passes antibodies to the piglets for their protection.
Introduction: Porcine Respiratory Disease Complex (PRDC) is a multifactorial syndrome which is a source of heavy economical losses. Its control implies herd management and therapeutic measures (vaccines, antimicrobials). Objective of this study was to assess efficacy of a multivalent vaccine to prevent PRDC and related losses in a Philippine herd. Materials and Methods: The study was performed in a farrow-to-finish herd with1,400 sows having a history of...

Introduction: Streptococcus suis ( S. suis ) is a major bacterial pathogen in pigs. Vaccination is a foremost strategy to reduce the impact of the infection and the antibiotic consumption due to this pathology. In France there is no available vaccine and autogenous vaccines are widely used, but there are no accurate and repeatable criteria for evaluating the efficiency of the vaccination. Field clinical observation on several farms is thus a tool for...

Introduction: Mycoplasma hyopneumoniae (Mhyo) and PCV2 cause significant economic losses to the U.S. swine industry. Circumvent® PCV-M G2 (Merck AH, USA) protects against both pathogens using two dosing options: single, 2mL intramuscular (IM) dose at 3 weeks of age (WOA) or older, or 1 mL IM as early as 3 days of age followed by 1mL dose 3 weeks later. The objective was to evaluate different vaccination dosing and timing protocols on PCV2 viremia and post...

Introduction: Foot-and-mouth disease (FMD) causes severe economical problems in livestock industry because of rapid spread and inducing low productivity. Thus, the administration of vaccines is a highly effective method for preventing FMD. In an effort to prevent and control FMD, Korea is currently implementing a vaccination policy. Despite all the hard work, Korea is suffering from recent FMD outbreaks of serotype O. FMD vaccines were evaluated characteristics, purity,...

Introduction: Mycotoxins are a group of structurally diverse secondary metabolites of fungi that can result in health problems in animals and severe economic losses. Pigs are naturally exposed to mycotoxins due to the high inclusion of cereals and by-products in their diets. Based on recent surveys, 70% of worldwide feed and feed raw materials are positive for at least one mycotoxin and 40% are found to be co-contaminated. Co-occurrence of mycotoxins is thus the norm and not the...

Introduction: The farm was a closed herd using AI and comprised 430 breeding sows. Progeny were kept until 10 weeks of age when they were sent to a second unit for finishing. The farm was infected with PRRS virus, as well as enzootic pneumonia (EP) (Mycoplasma hyopneumoniae), pleuropneumonia (Actinobacillus pleuropneumoniae) (APP) and streptococcal meningitis/arthritis (SM) (Streptococcus suis). The farm was planning to replace the weaning...

Introduction: Piglet weaning is an interesting model of oxidative stress (OS), but due to large inter-individual variations, there is a need to standardize in vivo response by applying usual challenges, such as vaccination (vacc) and heat stress (HS). The objectives of this trial are the development of a reproducible model of OS and the determination of the most accurate blood biomarkers. The effect of a combination of antioxidants was also investigated. Materials and...
