In the last Porcmag of July, find Chevance Céline’s ventilation technical sheet and its advice for calculating the need for extraction and choosing the appropriate equipment for your construction or building renovation project. Since the November-December 2022 issue, every month, you can find our recommendations for managing the atmosphere in pig farming.

Gwenaël BOULBRIA was granted by ECPHM for his project “Risk assessment of PRRSV vaccine strains transmission via residual presence in intramuscular or needle free injection devices” in partnership with Agence nationale de sécurité sanitaire – Anses. This study is part of our researches on PRRS virus and aim to investigate one of its transmission routes in farms. Thanks to the ECPHM board and the independent jury for selecting this project.

During the 14th ESPHM, held in Thessaloniki (Greece) from May 31th to June 2nd, Gwenaël BOULBRIA presented a retrospective study on enteric pathogens detection in 106 diarrhoeic cases. This study also reports the link between pathogens detection and the observation of histopathological lesions in the small intestine. This work is part of a larger project aiming to improve the understanding of neonatal diarrhoea to reduce mortality and the use of drugs during lactation.

Neonatal diarrhea in piglets is a daily concern for breeders, veterinarians and technicians. Mortality, loss of growth and the use of antibiotics that they generate oblige us to continue our research in order to better diagnose and better adapt our prevention plans. In the continuity of our previous study on the quality of the soup distributed to sows on the appearance of neonatal diarrhoea, our team has just published a second study in order to improve our knowledge when looking for the responsible germ, in partnership with Labocéa . The sole detection of a bacterium or a virus (by culture, genomic test or rapid test) is not sufficient to conclude on its pathogenic role in the disease, an observation of the lesions at the microscopic level is essential to conclude. Our study is a synthesis of the germs detected and the lesions observed in 106 piglets between 2020 and 2022 in order to link these inseparable diagnostic steps.
