In the present paper, an overview is given about Aujesky's disease (AD) eradication programmes currently applied in the different departments of France, together with the obtained results.

[Degradability in small bags of nitrogenous components of feed concentrates: standardization of the method and intra- and interlaboratory variability]. / Dégradabilité en sachets des matières azotées des aliments concentrés: standardisation de la méthode et variabilités intra- et interlaboratoires.

In sacco degradability of feed protein (DT) was measured in 13 feedstuffs by 4 laboratories according the French standardized procedure. Adjustment for variations in microbial activity by reference to DM disappearance of a standard sample of lucerne decreased within and between lab variability. When the standardized procedure was carefully followed, results were in rather good agreement between labs.
