Impact of porcine ear necrosis on weaned pigs

Porcine ear necrosis may have social causes among others risk factors already described.
A high incidence of social nosing, which can be an indicator of good social cohesion in a group, was significantly associated with less frequent lesions of ear necrosis;
A high incidence of oral manipulation of pen mates was significantly associated with more frequent lesions of ear necrosis;
Finally, the higher the increase in hydroperoxides and haptoglobin during the early post-weaning period, the higher the severity of ear necrosis.
Our study suggests that improving the welfare of piglets should be a first step in a farm dealing with porcine ear necrosis.

Rezoolution saw one of its wishes granted at the start of the year: Florent Peyre joined us on January 15.

Graduated from the Liège veterinary school in 2023 after a License 2 Life Sciences (Biochemistry & Biopharmaceutical Chemistry Option), he followed the ruminants/pigs course in his final year and developed a particular attraction for breeding audits and project management. He therefore has the ideal profile to complete our team in its breeding monitoring and clinical trial activities. It comes to us straight from the South East and the Alps. Welcome to Brittany Florent!

AFMVP 2023 Congress

Today, Arnaud Lebret presented the results of a study carried out on one of our farms at the annual meeting of French pig practitioners, the AFMVP congress. The aim was to assess the safety and efficacy, both clinically and in terms of antibiotics usage reduction, of a vaccine recently marketed in France. An original insight of this clinical study was to assess the vaccine’s efficacy through the presence of rotavirus in the environment (farrowing crate’s slatted floors, drinking bowls, door handles, etc.) before and after the vaccine was applied. Many thanks to Virbac for the confidence in our services.

Let’s go EAAP 2023 !

Théo Nicolazo started with the first of our four oral presentations, presenting the impact of social behaviours of weaned piglets on the prevalence and the severity of porcine ear necrosis. This study was conducted in partnership with Elodie Merlot and Caroline Clouard from INRAE.

He went on with a second oral presentation about the interest of Sow Caliper® measurement at insemination (compared with backfat thickness measurement with Renco®) to estimate body condition on different genetic types: influence on farrowing performances. Data from more than 1700 sows from 6 different farms were recorded.

The congress ended with two oral communications from Charlotte TEIXEIRA.
– The first one about antimicrobials usage reduction following the implementation of PRRS virus control measures (biosecurity and vaccination).
– The second one reported the development of an APP to detect sows at risk for stillbirth and to improve farrowing monitoring in order to reduce stillborn rate.
