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: 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...

Introduction There is growing advocacy for antibiotic-free (ABF) livestock production to minimize the emergence of antibiotic-resistant foodborne pathogens and subsequent human exposure to these treatment-refractory organisms [1–4] This trend has been driven by the escalating presence of antibiotic resistance, including multi-drug resistance, among a variety of important bacterial pathogens that infect both animals and humans [5,6]. In food-animal settings, resistant...

Introduction: There are two registered vaccines available (Clostriporc A, Enteroporc A, IDT Biologika GmbH) to prevent suckling piglet diarrhea caused by Clostridium perfringens type A (CpA). These are based on the α- and β2-toxoids. The goal of this study was to evaluate the development of antibodies against the α- and β2-toxins after recurrent vaccination of gilts with ENTEROPORC A under laboratory conditions. Materials and...

Introduction: The purpose of this study was to demonstrate the economic benefit and improved yield of groups of gilts vaccinated with SUISENG®, on a farm with a high prevalence of neonatal diarrhoea caused by E.coli/Clostridium . Materials and Methods: 49 clinically healthy, PRRSV-positive and ADV-negative gilts were selected on a farm with 800 sows, and divided into 4 groups, 2 vaccinated (V1 n=13; V2 n=12) and 2 not vaccinated (NV1 n=12;...
