Les productions animales sont soumises à des restrictions qui ont pour objectif de respecter le bien être animal et la sécurité de la chaîne alimentaire ou de contrôler les volumes de production et leurs impacts environnementaux. Ces dernières restrictions imposent des mesures de réduction du chargement en animaux par hectare et du niveau de fertilisation azotée et sont réglementées dans le cadre de la Directive Nitrate (91/676/EC). L’extensification des systèmes de production répond aux mesures encouragées par les politiques agricoles qui visent à réduire l’excèdent d’azote (N) dans des systèmes de production présentant intrinsèquement de faibles efficiences d’utilisation de l’azote. Le présent travail récapitule les résultats zootechniques, phytotechniques et environnementaux des systèmes de pâturage, pendant six années, pour trois catégories d’animaux (vaches allaitantes et veaux, taureaux et vaches laitières). Des protocoles semblables ont été utilisés pour les trois catégories, à savoir, un système avec fertilisation azotée et chargement conventionnel intensif (3/3 N), un traitement avec le même chargement et une fertilisation azotée réduite d’un tiers (2/3 N) et un traitement sans application de fertilisation azotée (0 N) avec un chargement adapté. Les résultats montrent qu’une réduction d’un tiers de la fertilisation azotée peut être envisagée pour réduire les excédents d’azote des systèmes de pâturage alors que les systèmes extensifs présentent des efficiences plus hautes d’utilisation de l’azote et des bilans azotés plus favorables, sans affecter le niveau ni la qualité des produits.

Porcine pleuropneumonia caused by Actinobacillus pleuropneumoniae is a frequent and highly infectious disease generating significant economic losses related to deficiency in zootechnical profits and intensive use of antibiotics. This synthesis aims to review the bacterium elements necessary to pathogenesis development. At first time, we describe activation, secretion and cytotoxic action of Apx toxins, recognized as A. pleuropneumoniae major virulence factors. Then, we develop the other ones which are the lipopolysaccharides, the polysaccharidic capsule, the fimbriae, iron and other nutrients capture systems, various proteases, installation of certain metabolic ways, flagella and the biofilm.

Depuis longtemps utilisé pour le suivi sanitaire et la gestion technique des troupeaux laitiers, le résultat du comptage cellulaire de tank et donc indirectement du comptage cellulaire individuel est devenu un critère officiel pour le paiement du lait et le contrôle laitier. L’étude est consacrée à l’évaluation d’un compteur à particules : le Coulter Counter® modèle Z2. Après calibrage primaire et étalonnage de l’appareil, une évaluation de ses performances a été réalisée par la détermination de la justesse, de la fidélité et des critères d’appréciation des analyses sur des échantillons de laits de quartiers. Pour l’appréciation de la justesse, les échantillons de lait ont été dénombrés au préalable par numération microscopique selon la méthode de Prescott et Breed (1910). Les résultats obtenus ont révélé une bonne corrélation (CC = 0,94) avec un coefficient de variation de 3,17 %. La fidélité, évaluée sur la base de la répétabilité (0,2 %) et de la reproductibilité (0,8 %) est de 1 %. Ces valeurs sont nettement inférieures aux normes préconisées par la Fédération Internationale de Laiterie (1995). La valeur diagnostique du matériel utilisé se trouve confirmée par les valeurs de 0,96 et 0,87 % obtenues respectivement pour la sensibilité et la spécificité. La confirmation de la qualité du matériel employé laisse entrevoir son utilisation possible à large échelle dans la Wilaya de Blida. À ce titre il constitue un outil irremplaçable de contrôle de la qualité et de valorisation du lait. [less ▲]

Infectious respiratory diseases also called ‘cat flu’ are nowadays one of the most relevant areas of feline medicine. Epidemiologic surveys revealed that 80% of the cases are due to feline calicivirus and Felid herpesvirus 1 (FeHV-1). FeHV-1 is an alphaherpesvirus that has a worldwide distribution in cat population. It is responsible for feline viral rhinotracheitis. This disease can be acute, chronic or latent. It is characterized by fever and respiratory or ocular signs among which conjunctivitis and keratitis are the most common. Severe cases can cause complete blindness of the cat mostly following repetitive reactivations. Latent viral carriers are epidemiologically important because they are the main source of infection to susceptible cats. Nowadays no vaccine can prevent infection. At best, available vaccines help to reduce clinical signs but fail to prevent establishment of latency or reactivation. Consequently, feline viral rhinotracheitis still represents a major problem in domestic cats. This review focuses on the current knowledge about feline viral rhinotracheitis and its etiologic agent, FeHV-1. [less ▲]

Certains Escherichia coli producteurs de Shigatoxines (STEC) sont responsables de toxi-infections d’origine alimentaire qui se traduisent par des diarrhées mais aussi par des syndromes plus graves pour l’homme comme le syndrome hémolytique urémique pouvant provoquer la mort. Il s’agit d’agents zoonotiques dont le réservoir principal est le bovin et les autres ruminants. Les principaux modes de transmission des infections à STEC à l’homme sont la consommation d’aliments contaminés (viande de boeuf peu cuite, produits laitiers non pasteurisés), la transmission de personne à personne, l’ingestion d’eau contaminée et le contact avec des animaux (notamment les bovins) et leur environnement. Les facteurs de virulence des Escherichia coli producteurs de Shigatoxines sont principalement les protéines codées par un îlot de pathogénicité, « Locus of Enterocyte Effacement », impliquées dans la formation de la lésion d’attachement et d’effacement et de la diarrhée et les toxines de Shiga codées par des bactériophages et impliquées dans les syndromes extraintestinaux. La souche de STEC du sérotype O157:H7 est responsable d’épidémies dans le monde causant des milliers de malades et des dizaines de morts. De nombreuses méthodes de diagnostic ont été développées pour identifier ce pathogène à partir des aliments. Elles regroupent des méthodes de bactériologie classique, des méthodes immunologiques et des méthodes moléculaires. Des mesures d’hygiène sont particulièrement importantes pour éviter la contamination des animaux à la ferme et celle de la viande à l’abattoir. Enfin, des modèles d’évaluation du risque ont été développés notamment afin de modéliser le comportement des STEC dans l’aliment. [less ▲]

The aim of this study was to assess the accuracy of judging age from teeth, with standard aging guides, of mares from 2 to 20 years old registered in the Belgian draft horse stud-book. The replacement of the deciduous incisors by permanent teeth occurred when expected as the disappearance of the infundibulum on the permanent lower intermediate incisors. The disappearance of the infundibulum was however observed until 16 months earlier than expected on the central incisors and until 18 months later on the corner incisors with 64 % and 50 % of the concerned mares respectively. The modifications of the shape of the occlusal tables from oval to round occurred from 1 to 4 years earlier than expected. The risk to attribute an older age than the true age during the so called round period is lower when taking into account the disappearance of the cup cement leaving only an enamel spot on the occlusal table surface. The modifications of the shape of the incisor tables from round to triangular and to biangular was also observed earlier than expected but only with the central and intermediate incisors, not with the corner incisors. The measurement on photographs of the profile angle of the corner incisors confirmed that this angle decreases with age from about 134 degrees at about 5 years to about 72 degrees at 20 years. Statistical analyses of the differences between real ages and those estimated on pictures by a college of three experts, show that ageing horses from their dentition is more accurate for animals of 8 years old or less, than for older ones. For those animals, the overestimation was about 10 % of the real age. [less ▲]

An ovarian cyst is classically defined as a fluid-filled space larger than 24 mm, that can persist for more than 7 to 10 days in the absence of a corpus luteum. The frequenc y of this pathology is between 7 to 15%. Contrary to the follicular cyst, the luteinised follicular cyst is characterized by the presence in its periphery of a luteal tissue. The ovarian cyst is a dynamic structure. Its presence doesn't interfere with the follicular waves but can modify their characteristics. An ovarian cyst results from or induces an absence of ovulation. Ovarian cyst diagnosis and especially the differential diagnosis between follicular and luteal cysts necessarily imply the use of ultrasonography to clearly identified their diameter and thickeness. The ultrasonography sensibility is better than that of transrectal palpation. Progesteronemia interpretation supposes the preliminary definition of a threshold. Behavioural(anoestrus or nymphomany), uterine(tonicity of the uterine horns) or vaginal (mucus) abnormalities can help to direct the diagnosis. [less ▲]

Several scientific studies revealed that substances with hormonal (or antihormonal) activity are widely distributed in the environment as well as in food, either as natural constituents (as phytoestrogens), or as substances of anthropogenic origin (for example, Several observations concerning both the wild fauna and humans indicate that these products with hormonal activity are endocrine disruptors. Numerous ecotoxicological studies evidenced important disturbances of the fertility of the wild fauna in zones contaminated by pesticides. In humans, epidemiological studies revealed a significant increase of certain cancers (among others, that of the testicles) and a decrease of the male fertility. Substances with estrogenic activity are often considered, but other hormonal effects are more and more frequently discovered (i.e. anti-androgenic). Numerous worries appear concerning the long-term effects on human health linked to a chronic exposure to these substances by food ingestion. It is urgent to review, not only on the actual contamination of our food by endocrine disruptors (in terms of identification and quantification of every individual chemical), but also the potentially toxic activity of food containing a mixture of contaminants present at levels below their individual toxicity threshold.

The degenerative osteoarthritis is a common source of disease in the horse, causing pain and leading finally to the destruction of the cartilage in the diarthrodial joints. The synovial membrane is a constitutive element of the joint, but often neglected due to its less obvious alterations, despite its crucial role. This review of literature considers the embryology, the histology of synoviocytes in vivo and in vitro, gives information about the production of inflammatory mediators, degrading enzymes, free oxygen radicals, about the composition of the synovial fluid and the interaction with chondrocytes. The number of studies on equine synoviocytes in osteoarthritis is very restricted, therefore we included studies in other species and other types of joint diseases to achieve a more complete image of the complex, interdependent and mutual acting mechanisms.

Foodborne disease have an important impact on the public health. In Europe and in the USA, Salmonella and Campylobacter are the two main bacterial causes because of their presence in the intestinal tract of poultry, pig and beef. For the monitoring of the bacterial contamination of food, the enumeration of certain groups or species of bacteria of intestinal origin is an alternative to the detection of the pathogenic microorganisms. They can be used as index indicating the possible presence of pathogenic agents having a similar ecology, or as indicators announcing the non-observance of the good practices. The most used are the total plate counts, E. coli and the Enterobacteriaceae. During meat production, they are counted at the level of environment, along the food chain, on carcasses at the slaughterhouse, on carcasses and in meat, in plants and distribution. Various surveys are carried out by the producers of food and the authorities for the control of the auto-control, the national inspection plans or to determine the national baseline. [less ▲]

Selenium and iodine deficiencies are frequently present in cattle in Europe with a negative impact on animal health, reproduction and production. Deficiencies in animals also influence human health owing to consumption of their products. These deficiencies must be correctly diagnosed in order to avoid lack of diagnosis or wrong diagnosis. Since there are many interactions between nutrients, a nutritional approach only is of limited interest. Therefore, the diagnosis based on samples obtained on the animals is more reliable. Clinical signs of selenium and iodine deficiencies are rarely pathognomonic. Laboratory analyses are thus necessary to confirm the diagnosis. The present review relates the principal clinical signs of selenium and iodine deficiencies and the confirmation of the deficiency by the measurements of different nutritional and functional markers available for cattle, either on blood, milk, urine or tissues. Finally, a protocol for the diagnosis of selenium and iodine deficiencies is proposed [less ▲]

The erythrocyte, as an oxygen carrier, is submitted to areas where oxidative stress is important. The maintenance of the structure and fluidity of its membrane is essential to its function. Indeed, oxygen must diffuse through the membrane and the deformability of the cell is essential to its progression through capillaries. The structure and, as a consequence, the fluidity of the membrane influence these properties. The red blood cell presents antioxydant capacities, but in some cases, free radical production is increased and exceeds antiradical defences leading to irreversible defects of the membrane, and, as a consequence, of its function. Horse erythrocyte seems to be more sensitive to oxidative stress than other species and resulting hemorheological changes could have tissular and organic consequences. [less ▲]

Human transmission of Salmonella enterica from new companion animals is usually suspected even though very few data according Salmonella infections in these animal species are available. The prevalence of Salmonella enterica infections in the digestive tract of 450 new companion animals ( 45 ferrets, 7 birds, 308 rodents, 82 rabbits and 8 reptiles) coming from pet shops or individual owners was determined by bacteriological examinations of anal swabs or pooled fresh faeces. Only one Salmonella Enteritidis strain was isolated from a ferret in a pet shop. The symptomatic or asymptomatic Salmonella carriage in ferrets, rodents and rabbits is thus not as frequent as what was suspected. [less ▲]
