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.
Frédéric Vangroenweghe (Elanco Animal Health) demonstrated the efficacy of an oral live non-pathogenic E. coli F4/F18 vaccine (Coliprotec®) for active immunization of piglets against post-weaning diarrhea, during IPVS2022 in Rio de Janeiro, Brazil....

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;...

Introduction - vaccines against parasites In modern swine medicine, vaccination against various pathogens is an integral part of the health management. However, currently not a single vaccine against parasites of swine is commercially available. Compared to viral and bacterial pathogens, there is a general scarcity for anti-parasite vaccines; only two anti-nematode vaccines, one antitick-vaccine and a handful of antiprotozoal vaccines are available for domestic animals....

A presentation prepared for the 24th International Pig Veterinary Society Congress and 8th European Symposium of Porcine Health Management at the Royal Dublin Society (RDS) Dublin, Ireland 8th June 2016. Porcine reproductive and respiratory Syndrome Virus (PRRSV) is the most economically significant infectious disease of swine worldwide. Due to the great impact of PRRS in many key swine producing areas of Asia, Europe and the Americas, the epidemiological situation created by...

Introduction For economic reasons, the pig industry is marked today by a phenotypic inbreeding for production parameters that might result in a genotypic linkage with an altered (compromised) immune responsiveness. A well-developed immune system and optimal immune responsiveness remain important for the welfare and productivity. Indeed these qualities can only be obtained if the health status of the animal scores high. Therefore a lot of energy and money is invested in...

1. Introduction With 1766–1768 nucleotides, porcine circovirus type 2 (PCV2) is the smallest genomic panzootic associated virus among the circular single-stranded DNA (ssDNA) viruses hitherto. These ssDNA viruses are remarkably understudied, and only recently have researchers begun to study these viruses due to the advent of next-generation sequencing in birds, fish, mammals, and even humans [1,2]. The small genome of PCV2 encodes at least nine different transcripts...

It is now possible to train the first line of defence system of animals. This will not only help to be better protected against diseases, it also creates a stronger and better vaccine response. This immune training can be done with beta-glucans from yeast. What are the benefits for pigs? We are more...

Introduction The emergence of Porcine reproductive and respiratory syndrome virus in the 1980s and early 1990s was a turning point in the ways in which diseases were dealt with in pig farms. The impact of the disease, its rapid spread worldwide (by 1993 the infection was present in America, Europe and Asia) and the unusual features of the virus made evident that a vaccine was urgently needed to try to control the infection. The first vaccine...

Introduction Streptococcus suis (S. suis) is a major porcine pathogen responsible for important economic losses to the swine industry. In fact, it is one of the main causes of bacterial death in post-weaned piglets, from 5 to 10 weeks of age. According to the Canadian Swine Health Information Network, S. suis-related diseases are the most common infectious problem reported in Canadian swine farms. In addition, the Monitoring and Analysis Working...
