In Belgium, the main economic penalty accounted for bovine milk quality is the bulk milk somatic cell count geometric mean over 3 months reaching more than 400,000 cells/ml. Yet, it is still difficult to make progress on udder health and milk quality because regional risks related to endemic farming practices are not broadly known. Hence, a first step in understanding specific udder health risks associated with herd management has to be a broad ecopathological survey. A random stratified sample of 349 dairy farms, representing 25% of producers registered for performance recording, was selected with a total of 16,000 cows. Thorough audits recording 400 farming practices were made in each farm by 2 different surveyors during milking. The practices were recorded across four categories: Herd structure, Housing, Milking practices and Herd Management (including Nutrition). Our chosen variable was the geometric mean of the herd composite somatic cell count from the last three months compared to the 400,000 cells/ml European threshold. The sample had a mean somatic cell count of 287,000 cells/ml following a normal distribution between 73,000 and 807,000 cells/ml. From 19 risk indicators identified through univariate logistic analysis (p<0.15), half were related to milking practices and 5 were underlined by significant odds-ratios (OR) found through multivariate logistic analysis (p<0.05). Therefore, it was found that cubicle housing had the least risk (OR= 0.59 compared with tightened stalls, OR= 0.42 compared with straw stalls); Presence of a calving pen (OR= 0.40), use of post-dipping (OR= 0.50) had a positive impact; whereas pre-dip had a negative impact in our study (OR= 3) though it was not clear if this routine was performed correctly. Stripping also had a bad impact on milk quality whether it was systematic (OR = 1.90) or occasional (OR = 2.43). It was also found that farms with poor milking liner hygiene had more trouble (OR = 2.34). The results were comparable to other ecopathological studies such as northern and southern American and European studies. This study is a prerequisite in operational veterinary advice in southern Belgium dairy farms, because it provides a cross-sectional study of dairy practices and states on major epidemiological risk factors in dairy management for this region.

The worldwide status of bovine tuberculosis (bTB) as a zoonosis remains of great concern. This article reviews the main risk factors for bTB in cattle based on a three-level classification: animal, herd and region/country level. A distinction is also made, whenever possible, between situations in developed and developing countries as the difference of context might have consequences in terms of risk of bTB. Recommendations are suggested to animal health professionals and scientists directly involved in the control and prevention of bTB in cattle. The determination of Millennium Development Goals for bTB is proposed to improve the control/eradication of the disease worldwide. [less ▲]

La mammite a de multiples origines et est souvent de type subclinique, rendant contrôle et surveillance difficiles. La majorité des études relatives aux mammites se caractérise par une approche individuelle. Le cadre expérimental restreint de celles-ci ne permet pas une interprétation précise des observations, à la suite du nombre limité de facteurs étudiés. L’approche choisie pour cette étude se veut globale et implique un grand nombre d’exploitations. Elle a pour objectifs d’identifier et de hiérarchiser, au travers d’une enquête, les caractéristiques générales de traite et les conditions environnementales des élevages laitiers influençant le statut sanitaire du pis [less ▲]

Haptoglobin and serum amyloid A are major acute phase proteins in cattle. Dairy cattle often develop pathologic conditions in the peripartum period; acute phase proteins may be useful in their diagnosis. Objectives: The purpose of this study was to compare the accuracy of serum haptoglobin (Hp) and serum amyloid A (SAA) concentrations with clinical health status for diagnosing disease during the peripartum period in dairy cattle. Methods: Dairy cows from 4 herds were evaluated every 15 days over a 6-month period. Health status was determined by thorough clinical examination. Haptoglobin and SAA concentrations were measured in serum using validated methods and the results were classifed as positive or negative based on defined cutoff points. Disease prevalence, sensitivity, and specificity were compared using clinical examination as the gold standard. Results: A total of 1896 samples from 158 cows were analyzed. Significant increases in mean Hp and SAA concentrations were observed in the week following parturition in both primiparous and multiparous cows, although high interindividual variability was observed. Both Hp and SAA had low sensitivity but higher specificity in determining disease status compared with clinical examination. Increased concentrations of Hp and SAAwere found in ,10% of samples from clinically healthy cows, except in the week after parturition. Conclusions: Haptoglobin and serum amyloid A should be used with caution as markers of inflammation in the week after calving. Poor sensitivity in other postpartum periods could be related to the higher incidence of chronic (vs acute) inflammation. Haptoglobin may be appropriate for routine screening, but further work needs to be done to assess its value as an indicator of herd health. [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 ▲]

Blood samples were taken from calves with respiratory disease the first day of examination for determination of the serum concentration of haptoglobin, fibrinogen, alpha-2- and gamma-globulins, and albumin. A clinical examination was performed daily for the duration of the disease. The animals were retrospectively classified in two categories: those animals requiring no treatment or antibiotics alone (group A), and antibiotics associated to anti-inflammatory drugs (group B). The serum proteins were tested in order to check whether they were able to distinguish, on the first day of clinical examination, between calves requiring anti-inflammatory treatment (group B) or not (group A). About 80% of calves were properly classified in both groups by the combined use of the two serum proteins haptoglobin and fibrinogen: these two proteins, and especially haptoglobin, were useful for the identification of calves requiring an anti-inflammatory treatment.
