The rabbit is an essential model in scientific research, particularly in the study of cardiovascular diseases such as hypertension and atherosclerosis and for the investigation of the osteoarticular system. Due to the fact that various factors (environmental, microbial, stress, pain.) can influence data obtained from experiments, special care must be given to housing conditions. Sensory enrichment (olfactive, auditive, visual or tactile stimuli) and physical enrichment (nutritional and social stimuli) allow rabbits to express specific behaviours and reduce stereotypies. This synthesis reminds of the importance of these factors and gives to the researcher some ways to control them. [less ▲]

The bovine mastitis : from initiation to resolution The cure of a cow suffering from a bacterial mastitis relies on the balance between the eradication of the pathogen and the resolution of the inflammatory response, two processes that are essential to come back to a normal milk composition with low somatic cell count. The persistence of the inflammatory response, which main consequence is a reduction in milk yield, is a feature of chronic mastitis. This frequent disease depends on inappropriate host-pathogen interactions and is not yet well understood. This review resumes the main defence mechanisms of the bovine mammary gland, emphasizing the predominant roles played by the neutrophil, and brings some precisions on lipoxin implications in the resolution of inflammation. Reasons that may explain the persistence of the inflammatory reaction, a phenomenon found in the Staphylococcus aureus chronic mastitis, are also discussed. [less ▲]

L’émergence de Salmonella Enteritidis dans l’industrie avicole a eu lieu dans tous les pays occidentaux entre 1965 et 1980. Depuis lors, ce sérotype est devenu le plus commun chez la volaille. Comme il se transmet verticalement dans les oeufs, il constitue la cause principale de la pandémie de salmonellose non-typhoïde qui est observée chez l’homme. En outre, la bactérie se transmet aussi horizontalement dans les exploitations de volaille. Une fois qu’un bâtiment a hébergé des poules contaminées, il est très difficile d’éliminer cette contamination par les mesures hygiéniques classiques. Le mécanisme de transmission dans les oeufs n’est toujours pas complètement élucidé, ce qui constitue un obstacle majeur pour le développement de nouvelles mesures de prévention et de traitement. Les produits et mesures actuellement disponibles pour lutter contre Salmonella chez la volaille ont été largement développés sur base de méthodes empiriques. Néanmoins, la situation actuelle impose de prendre des mesures. Au niveau européen, de nouvelles dispositions législatives prévoient une série de mesures visant à réduire les taux de contamination de Salmonella tout au long de la chaîne de production, de transformation et de distribution des oeufs et de la viande de volaille. Il est évident que les contaminations des oeufs et de la viande sont fortement influencées respectivement par les conditions hygiéniques de l’abattage et par la réfrigération des oeufs. Au niveau belge, l’Agence fédérale pour la Sécurité de la chaîne alimentaire (AFSCA) va mettre en place un nouveau programme de lutte dans le secteur avicole. Cet article passe en revue les aspects les plus importants de l’épidémiologie, de la pathogenèse et décrit les mesures de prévention et de lutte qui sont disponibles à l’heure actuelle. [less ▲]

Plusieurs années d’efforts de recherches témoignent que l’élevage des ovins Djallonké est une activité majeure dans l’Afrique subsaharienne, si l’on en juge par la masse des connaissances produites. Les auteurs, au travers d’un inventaire des différentes contributions scientifiques et techniques de 1967 à 2004, rapportent les performances de reproduction et de croissance des ovins Djallonké et les facteurs de leur variation. Les performances de reproduction ont été évaluées au travers de six critères zootechniques : cyclicité sexuelle annuelle, précocité sexuelle, intervalle entre agnelages, productions laitières, prolificité et mortalité des agneaux. Les performances de croissance ont été étudiées pendant deux périodes : la période d’allaitement naturel (croissance entre naissance et sevrage) et la période post sevrage. Les estimations des paramètres génétiques (héritabilité, corrélations génétiques et phénotypiques, répétabilité) de quelques caractères de reproduction et de croissance, ainsi que les résultats d’amélioration génétique, ont été passés en revue. Les conseils pratiques sont loin d’être uniformes étant donné la grande diversité des conditions d’expérimentation et d’analyse entre les différentes publications. [less ▲]

Among the most important elements of the nursery pen design, the feeder allows or not the optimisation of pigs' performance. Two principal design features can characterize a feeder : the way pigs will be fed ( wet, dry or wet/dry) and its capacity, which depends in turn on the trough length or the number of feeding spaces ( mono - or multi- space feeder and communal trough). To determine the number of pigs that can be accommodated per feeder, the daily time spent per pig at the feeder - depending on pig size and feed delivered - must be taken into account. Recommendations of 4 to 10 weaned pigs per feeding space are generally given. Pigs are able to adapt their eating behaviour when crowding occurs but suboptimal situations may reduce feed intake and productivity and even impair welfare. Some particularities of the feeder such as limited depth, feeder gap opening, lip height, side panels or protective crate can limit feed spillage and/ or agonistic interactions at the feeder. Feeder position in the pen should prevent pigs to be disturbed while eating and allow free movement of penmates. [less ▲]

Porcine stress syndrome is related to a point mutation in Ryr1 gene encoding the ryanodin receptor. This syndrome involves mortality after stress conditions or poor quality meat. Five hundred and five individuals among 5 Belgian production systems were genotyped. This genotyping was performed by polymerase chain reaction-restriction fragment length polymophism (PCR-RFLP) or real time PCR. The results indicated that 22,4 % of the pigs were stress sensitive (TT genotype) and 77,6 % stress resistant (63,4 % CT heterozygotes and 14,2 % CC genotype). Statistical analysis allowed to split the production systems into two groups: the production system 1 and 2 presenting a high level of TT individuals (44 % and 52 % respectively) although production systems 3, 4 and 5 presented a high level of heterozygotes individuals (74 %, 92 % and 78 % respectively). At the technical level, real time PCR appeared to be a faster and an easier technique than PCR-RFLP. [less ▲]

The characterization of the gastric aspartic proteases and the understanding of their mechanisms of activation led to several applications in many domains as the use of chymosin in cheese industries and the diagnostic of gastric diseases in humans and animals. Particularly, in cattle, the indirect measurement of pepsinogen activity is largely used for the diagnosis of ostertagiosis. Today, the gastric strongyloses are responsible for serious problems of management or the emergence of parasites resistence towards antihelminthics, and no immediate solution is available. Nevertheless, several tracks are proposed such as a more rational use of antihelminthics by the study of blood pepsinogen. This approach held our attention. The present review describes bovine pepsinogen and prochymosin, with an accent on the zymogen structure, their mechanisms of activation and the methods of blood levels measurement. The manuscript will end on the importance of the problems raised by gastric worms, and on the interest of the measurement of blood pepsinogen in the management of these diseases in cattle. [less ▲]

Urethral sphincter mechanism incompetence is characterized by unvoluntary urine leakage, worsening when the animal is recumbent or asleep, or during excitement. It mainly affects large breed dogs, and mostly middle-aged spayed bitches. The aetiology of this condition is multifactorial and predisposing factors include a decrease urethral tone, an intrapelvic bladder neck position, a short urethra, sterilisation, obesity, and age. Diagnostic workup should include a vaginourethrography to identify possible vaginal abnormalities and to visualize the urethra and the position of the bladder neck, and urethral profilometry to demonstrate a decrease in maximal urethral pressure and functional profile length. Medical treatment with oestriol is an option. This short-acting oestrogen does not exhibit oestrogenic side effects. Unfortunately, its success rate is only of 65 % of complete continence. The a- adrenergic agents ( phenylpropanolamine and ephedrine) are more efficacious, with a success rate reaching 75 to 90 %, with very few side effects. In absence of response to the treatment, or if the animal becomes refractory, a colposuspension can be recommended, with a fairly good prognosis. [less ▲]

This work compares two dramatically different types of wildlife management in Senegal, a country threatened by poaching and deforestation : the first concerns the management of the Niokolo Koba National Park, by a public utility service and the second, the management of the Bandia Reserve, a fenced area which surface is more than thousand times lower, by private investors. In order to do this comparison, the structure, type of management, evolution of flora and fauna, and management problems encountered for each protected area are analysed. This comparison allows to formulate some recommendations for a sustainable management of Senegalese wildlife. [less ▲]

Among acute phase proteins, haptoglobin is considered as the most interesting in cattle. Due to its early and marked increase in acute inflammation, it is useful for the diagnosis and prognosis of acute inflammation and for the evaluation of treatment. Physiological variations of its serum concentrations can be observed in the days following parturition. From very low or even undetectable concentrations, its serum levels can rise significantly during acute inflammation. Haptoglobin could improve the sanitary control of animals and the identification of pathologies even before clinical signs become apparent. It could also detect subclinical diseases and improve the sanitary control at the slaughterhouse, because haptoglobin has a good combination of specificity and sensitivity in such a context. At the herd scale, it could be used to evaluate the sanitary status in order to allocate it a quality label. [less ▲]

Microarray technology is a miniaturized biotechnological tool with potential applications for study and analysis of multiple molecular compounds as proteins, lipids, carbohydrates or nucleic acids. The nucleic acids microarray technology focuses interest of scientists for fifteen years because of its huge potential as regard to the scientific research, clinical diagnosis, and development of new drugs. Only DNA microarrays are investigated in this paper. Born from the conjunction of micro-electronics, biochemistry, molecular biology, and image processing, microarrays allow to analyse several thousands of genetic information simultaneously. Thanks to this new tool, it is possible in parallel to identify, to even proportion, a considerable number of nucleic acid sequences contained in a biological sample (blood, biopsy, water, food, etc). This article proposes, after having considered the operating mode of the microarrays, to understand their quality standards as well as their advantages and disadvantages. The two following parts are devoted to the place the microarrays occupy in scientific research and in the establishment of a clinical diagnosis. Finally the last part evaluates prospects the microarrays offer in veterinary sciences. [less ▲]

Energy metabolism of skeletal muscles in cattle is characterized by several specificities, mostly related to particularities of the digestive physiology. Energy metabolism of muscles relies on preferential utilization of some nutrients, such as volatile fatty acids and ketone bodies on the one hand, and glucose on the other hand, the contribution of non-esterified long chain fatty acids being limited. As for other species, nutrients utilization is influenced by the nature of muscle fibers, leading to preferential metabolic pathways. Energy metabolism can be either more oxidative, oxido-glycolytic, or glycolytic. Close relationships are found between energy metabolism, chemical composition of muscle - more particularly its fat level - and organoleptic quality of meat. [less ▲]

From a biochemical point of view, in ruminants, there are two major groups of fatty acids. They are firstly the volatile fatty acids from the rumen metabolism of dietary carbohydrates, and secondly the fatty acids from the rumen metabolism of lipids. This second group is made of the fatty acids synthesized by the microorganisms of the rumen and the fatty acids originating from the hydrolysis of dietary triacylglycerols, which are mostly hydrogenated by microorganisms in the rumen before intestinal absorption. In such conditions, the absorbed fatty acids are always more saturated than the ingested fatty acids. [less ▲]

Double-muscling in cattle is a generalised hypertrophy of skeletal muscle resulting from a hyperplasia of the myofibers. Using a positional cloning strategy, we have identified the gene underlying double-muscling, namely myostatin, and causal loss-of-function mutations therein. Myostatin is a novel member of the TGF-beta superfamily of growth and differentiation factors. Using conditional gene targeting in a murine model, we have demonstrated that post-natal muscle specific inactivation of the myostatin gene causes full-blown double muscling. This demonstrates the potential value of myostatin antagonist whether to promote muscle regeneration in patients suffering from muscle wasting disease, or to enhance meat production in livestock species. Finally, by targeting a myostatin transinhibitor on the Y chromosome, we have demonstrated in the mouse the feasibility of a more efficient cattle production system combining superior beef production abilities for bulls and dairy abilities for cows.

A comparison of somatic cell count and antimicrobial susceptibility of subclinical mastitis pathogens in organic and conventional dairy herds.Bovine subclinical mastitis is the most important disease affecting dairy cows. The fluctuating increase in somatic cell count (SCC) that occurs causes major economic losses in dairy industry. This comparative study between conventional and organic dairy herds was conducted in the aim to better characterize which consequences might have different management practices on SCC but also on the frequency of pathogens isolated and their antimicrobial susceptibility. Four conventional and four organic herds, with bulk milk SCC >300x103cells/ml were selected, in which respectively 47 and 44 cows were investigated. Each quarter was sampled 3 times at 15 days interval for SCC, microbiological analysis and antimicrobial susceptibility. In both herd categories, major pathogens isolated were by order of importance Streptococcus uberis, Staphylococcus aureus and Streptococcus dysgalactiae with a great impact on SCC. Coagulase negative staphylococci were the most frequent minor germs and had a moderated but real impact on SCC. In certified organic dairy farms, the three most frequently isolated major pathogens were significantly more susceptible to antimicrobials in vitro. This study suggests that the limited use of antibiotics in organic dairy herds could explain, at least in part, the lower resistance obtained from analysed isolates. [less ▲]
