| dc.description.abstract | The aim of this study was to make an inventory of the total production and use of autogenous vaccines in the Dutch pig industry in 2011 and to investigate the arguments to start using an autogenous vaccine. Finally, recommendations were given to improve the current legislations of autogenous vaccines. Two different surveys were formulated, one for the veterinarians working in the Dutch pig industry and one for the producers of autogenous vaccines in the Netherlands. The veterinarians received questions about the use of autogenous vaccines on Dutch pig farms in 2011, the producers received questions about the total production and the production process of autogenous vaccines for the Dutch pig industry in 2011. Each veterinary practice used autogenous vaccines. An average of 11.72 percent of sow farms used autogenous vaccines and 18.96 percent of the total sows were vaccinated with an autogenous vaccine. Autogenous vaccines were used for Streptococcus suis, Staphylococcus hyicus, Pasteurella multocida, Bordetella bronchiseptica, Actinobacillus pleuropneumoniae, Clostridium perfringens, Clostridium difficile and Escherichia coli. There was a big difference in total production between the different Dutch producers of autogenous vaccines (40 liters ' 520,5 liters). The producers produced autogenous vaccines for Streptococcus suis, Staphylococcus hyicus, Bordetella bronchiseptica, Pasteurella multocida, Haemophilus parasuis and Clostridium spp. | |
