[more ▼] Application of phosphorus (P) fertilizers to agricultural soils should be based on sound knowledge about soil P reserves, availability and lability to optimize conditions for plant uptake while limiting P transport to surface waters. This study investigated relationships between parent material (PM), land use and P fractions in agricultural soils at a regional scale. Surface and deep (100–120 cm) soil samples were collected from 120 agricultural sites (240 total samples) and analysed for three P forms (inorganic, organic and available) as well as for additional key properties. Land uses within the study area were continuous cropland, permanent pasture and temporary grassland. The area covered the 12 most common parent types in Wallonia. Mean total P contents were 904 and 401 mg/kg in surface and deep samples, respectively, with a 33% coefficient of variation for both horizons. The organic P fraction represented, on average, 30% of total P, while available P corresponded to 9% of total P. The influence of PM was apparent in both the surface and deep soil samples, while land use influenced only surface properties. The pattern in total P content relative to land use was pasture ≥ cropland ≥ temporary grassland. Correlation analyses highlighted significant relationships between edaphic parameters viz Alox, Feox, CEC, TOC, pH and P content, the main soil parameter being Alox which determines P sorption capacity. An enrichment factor was used to distinguish between geogenic sources and human activities in terms of topsoil P content.

[more ▼] The present study aimed to monitor skin test practices as performed by veterinarian field practitioners in Belgium. For this purpose, an anonymous postal questionnaire was elaborated and dispatched to veterinarians involved in bovine tuberculosis detection. The questionnaire included items focusing on the skin test performance. International experts in the field of bovine tuberculosis were asked to fill the questionnaire and a scoring scale was built as follows: 0='ideal' answer, 1=acceptable answer, whereas 2=unacceptable answer. Furthermore, experts were asked to rank the questionnaire's items according to their possible impact on the risk of not detecting reactors. A global score was further calculated for each participant and a comparison of practices was carried out between the two regions of the country, i.e. Wallonia and Flanders. Significant differences were observed between both regions, a harmonization at the country level is thus essential. No veterinarian summed a null score, corresponding to the ideal skin test procedure, which suggests that skin-testing is far from being performed correctly. Field practitioners need to be sensitized to the importance of correctly performing the test. The authors recommend the questionnaire is suitable for application in other countries or regions [less ▲] Detailed reference viewed: 23 (6 ULg)Assessment methodology of the intradermal tuberculosis skin test performed in cattle by field practitionersHumblet, Marie-France ; ; et alPoster (2010) Detailed reference viewed: 13 (1 ULg)Le sanglier wallon est-il un réservoir potentiel du virus de la maladie d’Aujeszky pour les élevages porcins ?; ; Saegerman, Claude in Epidémiologie et Santé Animale (2006), 49 With the screening organized for the monitoring of the classical swine fever in wild boars in Walloon area, a serologic investigation concerning the SuHV1 virus was undertaken between September 2004 and ... [more ▼] With the screening organized for the monitoring of the classical swine fever in wild boars in Walloon area, a serologic investigation concerning the SuHV1 virus was undertaken between September 2004 and December 2005 into approximately 2 300 wild boars. This survey is based on in-house commercial Elisa test validated for wild boar. This study shows the existence of an endemic infection of the Walloon wild boars by Pseudorabies virus, with important sub-regional disparities. The preliminary analysis of various parameters (age, sex, season or month of sampling), according to the biology of wild boars, makes it possible to wake up or confirm tracks concerning the pathogenesis of the infection in this species.

[more ▼] In 1998 werden 6 runderen tussen de 54 en 71 maanden ouderdom, afkomstig van de provincies West-Vlaanderen (3 gevallen), Oost-Vlaanderen (2 gevallen) en Luik (1 geval), gediagnostiseerd als gevallen van boviene spongiforme encephalopathie (BSE). De hypotheses betreffende de oorsprong van de infectie op zijn de volgende : het optreden van sporadische gevallen zonder duidelijk definieerbare oorzaak; de mogelijke kruiscontaminatie tussen voeder voor monogastrische dieren met daarin dierlijk meel en voeder voor herkauwers waarin geen dierlijk meel is verwerkt en dit tijdens het fabricatieproces, de stockage, het transport of de distributie; het gebruik van dierlijk beendermeel in het voeder voor runderen geproduceerd voor de ban (van kracht vanaf 27/7/1994). Algemeen kan men dus stellen dat in België de aanwezigheid van gecontamineerd diermeel als risicofactor voor BSE niet kan worden uitgesloten. De oorsprong van deze diermelen kon nog niet gedetermineerd worden.
