This work seeks to analyze the carbon balance of a managed permanent grassland grazed by the “Blanc Bleu Belge” breed of cattle. The study site is located at Dorinne. The experimental field was equipped with an eddy covariance system that measured CO2 fluxes and with a micrometeorological station. Carbon exported through mowing, imported through compost application or through complementary feeds for cattle was also measured. Carbon lost through CH4 emissions was finally estimated, allowing the establishment of a full C budget. In addition, the vegetation development was followed in order to estimate herbage production and dry matter intake by grazing animals. First year full carbon budget is presented and discussed, in relation with climate conditions and management practices. [less ▲]

Ces dernières années, la progression de la production avicole en Wallonie est, en grande partie, liée au développement de filières dites de qualité différenciée. En 2009, ce sont près de 2.000.000 de poulets qui ont été associés à ce type de production. Cependant, contrairement au poulet standard pour lesquels les pratiques sont très standardisées, les pratiques d’élevage en qualité différenciée peuvent varier, notamment la génétique, l’âge et le poids à l’abattage, le sexe de l’animal, l’accès à un parcours… Ces variations peuvent influencer l’homogénéité de la qualité organoleptique de la viande de poulet au sein d’une même filière ainsi que la perception (et la confiance) des consommateurs vis-à-vis de la viande des poulets qui en sont issus. L’objectif de ce projet est d’étudier et d’objectiver de manière scientifique la qualité organoleptique de la viande de poulet de chair au sein de trois filières avicoles de qualité différenciée afin de fournir aux détenteurs de ces filières des informations quant aux facteurs susceptibles de modifier la qualité organoleptique de leurs produits ainsi que la perception de ceux-ci par les consommateurs.

For many years, Salmonella infection models have been developed in chickens with the aim to study the effects of prophylactic or therapeutic measures on the colonization of the gut. However, although the literature includes numerous challenge models, few studies investigated the infection rates among the inoculated population. We have implemented an antibiotic pretreatment of the chickens (vancomycin hydrochloride, 25 mg/bird) as an infection promoter. Indeed, vancomycin affects the normal gut microflora and releases sites for Salmonella at the intestinal epithelium. Two experiments were undertaken and a presence/absence cloacal swab method was used to evaluate cecal colonization. In the first experiment, birds were orally inoculated with Salmonella Typhimurium at 21 days of age. Three inoculum doses (3 × 103, 3 × 106, 3 × 109 cfu/bird) and an uninfected control were compared according to whether or not vancomycin had been used. Higher levels of Salmonella colonization (more than 70 %) were achieved in the gut by pretreating birds with vancomycin before inoculation (P < 0.05). In the second experiment, chicks were inoculated at 7 days of age with 108 cfu/bird after a vancomycin pretreatment, leading to an infection rate of 87.5 %. In conclusion, vancomycin promotes efficiently the percentage of colonized birds in the challenged population, with either young animals or olders. [less ▲]
