When can a veterinarian be expected to detect classical swine fever virus among breeding sows in a herd during an outbreak?

The herd sensitivity (HSe) and herd specificity (Hsp) of clinical diagnosis of an infection with classical swine fever (CSF) virus during veterinary inspection of breeding sows in a herd was evaluated. Data gathered from visits to herds during the CSF outbreak in 1997-1998 in The Netherlands were used for the analysis. Herds were visited one or more times by the same or by different veterinarians. On the basis of the veterinarians' reports, each visit was coded as 0 (negative clinical diagnosis) or 1 (positive clinical diagnosis). The HSe for clinical diagnosis of CSF was modelled as a function of days elapsed since introduction of the virus. The moment of introduction of the CSF virus in the CSF-positive herds was unknown, so for each herd, a probability distribution for the unknown number of days since introduction was derived from serum samples collected at depopulation. The information from the reports of the veterinarians and from the test results of the serum samples at depopulation was combined in a Bayesian analysis. Data from CSF-negative herds were analysed to estimate HSp of clinical diagnosis of CSF. The HSe of clinical diagnosis was 0.5 at 37 days after virus introduction (95% CI: 31, 45) and reached 0.9 at 47 days after virus introduction (95% CI: 41, 54). The estimated herd specificity was 0.72 (95% CI: 0.64, 0.79). Dependence of HSe and HSp on characteristics of the veterinarians and the herds also was studied. Specialisation of the veterinarian significantly, although not markedly, affected the HSe.     

Canine obesity: is there a difference between veterinarian and owner perception?

Objectives : The overall aim of this study was to examine the nature of the relationship between dog‐ownership and canine obesity, explored in two cohorts of overweight/obese or non‐overweight dogs (n=125). This paper concentrates on the owners’ perception of dog weight. Methods : A researcher‐mediated questionnaire was used to collect data from dog owners attending a small veterinary practice. Interviewees (n=121) were asked qualitative and quantitative questions, designed to examine the owners’ views of their relationship with their dogs. Results : Although a high proportion of owners claimed to have discussed the dog's weight with their veterinarian, some discrepancies were apparent between owner perception of animal weight and the veterinarian's evaluation of body condition score. Owner disagreement was significantly greater for the veterinarian‐defined overweight dogs (P=0·005). Owners often provide personal narratives to account for their dog's weight status. Clinical Significance : This study confirms the important role of the vet in providing information about the issue of dog weight but also suggests that providing verbal information is sometimes insufficient. The study also indicates the potential value of qualitative research methods to further understand client perception of complex animal care issues and highlights the need for further in‐depth research.     

The global veterinarian: the why? The what? The how?

Globalization has created an entirely new landscape for veterinarians. Opportunities abound to meet the formidable challenges presented as animals, people, and microbes travel at a previously unimagined speed, fueled by the engine of commerce, resulting in a plethora of new diseases, issues, and partnerships. Re-tooling our profession to ensure that we can continue to fulfill our veterinary oath in the face of these changes will require both short- and long-term changes. It is essential that a single overarching, non-affiliated organization be formed to tie together all entities, providing the structure to create needed synergy to enhance our currently fragmented professional responses and to solicit funds to effect necessary changes.     

Where are the food animal veterinarian shortage areas anyway?

In 2010 the United States implemented the Veterinary Medicine Loan Repayment Program (VMLRP) to address perceived regional shortages in certain veterinary occupations, including food animal practice. With county as the unit of analysis, this paper describes a pair of models to evaluate factors associated with being designated a private practice shortage area in 2010. One model is used to explain food animal veterinarian location choices so as to provide an objective evaluation of comparative shortage. The other model seeks to explain the counties chosen as shortage areas. Model results are then used to evaluate the program. On the whole the program appears to perform quite well. For several states, however, VMLRP shortage designations are inconsistent with the food animal veterinarian location model. Comparative shortage is generally more severe in states that have no VMLRP designated private practice shortage counties than in states that do.
