Field Evaluation of the Efficacy of Vaccination against Porcine Proliferative Enteropathy Depending on the Vaccination Protocol and Farm Management System
نویسندگان
چکیده
The purpose of the study was to determine the efficacy of Enterisol Ileitis vaccine administered orally in water against porcine proliferative enteropathy. For a comparison, two administration protocols were used for the vaccination: individual oral drench or via drinking water accessible to the herd. The efficacy of the vaccine was studied on breeding, commercial, and fattening swine farms. As has been found, the percentage of immunised pigs that required further therapeutic action, during the fattening period, was significantly lower than that observed in the control (non-treated) group. Besides, the number of culled and Lawsonia intracellularis positive pigs was reduced. Better efficacy was found with individual oral drench applications than via drinking water. In addition, the vaccination had a positive impact on daily weight gain. In general, better results were observed on breeding and commercial farms than on fattening farms.

Background A controlled randomized trial was performed on a well-managed conventional French 180-sow farm. The trial compared the growth performances of piglets vaccinated at weaning (single shot) either with a commercial monovalent Mycoplasma hyopneumoniae bacterin vaccine or with a commercial bivalent vaccine (Porcilis® PCV M Hyo) against M. hyopneumoniae and porcine circovirus 2 (PCV2).
