Bridging the gap between veterinary student interest and professional demand for poultry-specialized veterinarians: a French experience.

Recent crises concerning poultry production revealed a relative deficit in the availability of veterinary competencies to manage some acute public health and animal welfare concerns. Veterinary education might be critically questioned about this deficit. The authors present the experience of the education program on poultry production medicine at the Veterinary College of Nantes in France over a 10-year period. First, the program consists of integrative teaching focused on a holistic multidisciplinary approach to this professional field on a compulsory basis. Evaluation of the course by the students through a questionnaire (N=1,032) showed a large favorable consensus. Second, the completion of an elective program targeting profession-specific competencies may allow the student to challenge his or her choice of this professional orientation in the undergraduate curriculum. According to the importance they want to give to poultry, and concurrently to other species, students have the possibility of building a curriculum that is either partly or fully devoted to poultry production medicine: a 6-month thesis, 2-10 weeks of professional training, 2 weeks in the field to solve a poultry flock health problem, and 2-4 weeks of specialized courses in poultry production medicine. To round off this curriculum, the national post-graduate program in poultry production medicine is highlighted, as well as its links with the residency program of the European College of Poultry Veterinary Science.

Genital form of pasteurellosis in breeding turkeys infected during artificial insemination and isolation of an unusual strain of Pasteurella multocida.

A genital and potentially fatal form of Pasteurella multocida infection was reported on two turkey-breeding farms on which birds were vaccinated against Pasteurella multocida. Both outbreaks were linked to the use of semen from young vaccinated toms with a history of respiratory pasteurellosis followed by treatment during rearing. Typing by agar gel immunodiffusion and rapid slide agglutination of P. multocida isolated from cloacal swabs was completed by multilocus sequence typing. Restriction enzyme analysis showed that that the isolates were clonal. They belonged to sequence type (ST) 30, described in chickens, cats, and ducks. This strain differed in sequence type from the ones used in the vaccine (ST8, ST60, ST53, and ST235), which might have limited its effectiveness. No contamination of the semen (n = 30) was found, suggesting fecal contamination during semen collection.

A case-based learning approach for teaching undergraduate veterinary students about dairy herd health consultancy issues.

A case-based learning (CBL) format was implemented at the Veterinary School of Nantes, France, for veterinary students in their last year of the curriculum who had chosen to track toward a farm animal career. The focus of the CBL format was learning about dairy herd health consultancy. The goal was to emphasize teamwork among students, introduce professional communications and advisory relationships with clients, and work within the technical and economic limitations of participating farms. These farms volunteered to participate and had identified a problem. The learning objectives included gaining basic knowledge of herd-level diseases and the methods to control these within herds. The program focused on health audits of dairy farms performed by teams of four to five students, culminating in submission of a herd health management action plan specific for the farm visited by each team. The CBL program was comprised of defined learning objectives for each team. The learning process was supervised, from orientation through to validation, by a panel of experts from within the veterinary school and from local industry. Teams submitted written reports that listed recommendations and an action plan for implementation. This report was defended by each team in front of the farmers, their professional partners, and the panel of supervisors. Assessment of the program by students, participating farms, and industry professionals was positive.

Factors associated with carcass contamination by Campylobacter at slaughterhouse in cecal-carrier broilers.

A study was conducted in 2009 to identify risk factors of Campylobacter spp. transmission from the digestive tract to the carcasses of standard broilers (slaughter age: 37 day, carcass weight: 1.3 kg on average). Counts of Campylobacter were performed on pools of 10 ceca and 10 neck-skins from 108 Campylobacter ceca-positive batches in three slaughterhouses. Technical and health data also was collected on the broilers: age, size, carcass weight (mean and standard deviation), condemnation rate, mortality rate and nature of treatment during the rearing period. Cecal counts varied from 4.8 to 10.2 log(10) cfu/g. In seventeen batches (15.7%), the skin count was below the detection limit. In the 91 batches with positive neck-skin test results, the counts varied from 2.0 to 5.2 log(10) cfu/g. Standard deviation of carcass weight, condemnation rate, slaughter rate and cecal count were significantly lower and growth rate higher in the 17 batches where neck-skin results were not detected positive. Multivariate analysis showed that batches with higher standard deviation of carcass weight were 5 to 9 fold more at risk of having detectable carcass contamination. Among the 91 positive neck-skin batches, only slaughter rate and cecal counts were found to have a significant but limited effect on the level of neck-skin contamination. As far as body weight homogeneity may be affected by disease, better health control can contribute to a reduction of the contamination of the broiler carcasses in Campylobacter carrier batches.
