Belgian Blue (BB) beef cattle is particularly prone to selenium (Se) deficiency due to the poor Se content of soil and roughages on rearing farms and the higher requirements of this hypermuscled breed. The goal of this trial was to compare the effects of different forms and concentrations of Se supplementation on Se status, health and performance in 60 pregnant Se-deficient BB cows. Cows were allocated to 3 experimental groups receiving selenized-yeast at 0.5 ppm Se on total ration (Y-Se 0.5), Na-selenite at 0.5 ppm Se on total ration (Na-Se 0.5) and Na-selenite at 0.1 ppm Se on total ration (Na-Se 0.1), respectively. Cows were supplemented from 2 months before calving until 2 months after calving. Data on performance, health and Se status of the dams and their calves were analyzed using a linear model, least squares means and logistic regression. At the end of the study, plasmatic Se (pSe) was significantly higher (P<0.01) in cows receiving Y-Se than in cows from other groups. Glutathion-peroxidase in erythrocytes (GSH-pxe) was higher in Y-Se and Na-Se 0.5 than Na-Se 0.1 group (P<0.01). Se content in colostrum and milk was significantly higher (P< 0.01) in Y-Se than other groups. At birth, Se status of calves from group Y-Se was significantly higher than those of other groups (P<0.01). Plasmatic Se in calves remained higher for 75 days after birth in Y-Se compared to other groups (P<0.01). Diarrhoea was the most commonly observed disease in the calves and, during the first 15 days of life, diarrhoea occurred in 6%, 21% and 35% of calves from groups Y-Se, Na-Se 0.5 and Na-Se 0.1, respectively. Over the whole 75 days trial period, incidence of diarrhoea was 19, 29 and 65%, respectively. Average daily gain (ADG) in calves born from Y-Se group of cows tended to be higher than in Na-Se 0.5 (P=0.06) and Na-Se 0.1 (P<0.05) but there was no difference between Na-Se 0.5 and Na-Se 0.1 (P>0.1). At the same dosage, Y-Se conferred better Se status in both dams and their calves than did Na-Se. Requirement of 0.1 ppm Se seems to be insufficient in BB to optimise health and performance. Regarding health status and ADG in calves, Y-Se seems also to result in better performance. (C) 2007 Elsevier B.V. All rights reserved. [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 ▲]

La fièvre catarrhale ovine (FCO) a été identifiée au Nord de l’Europe le 14 août 2006. L’Allemagne, la Belgique, les Pays-Bas et, dans une moindre mesure, le Grand-Duché de Luxembourg et la France ont été affectés. Le sérotype 8 du virus de la FCO (exotique) a rapidement été identifié ainsi qu’un vecteur, Culicoides dewulfi, une espèce indigène du Nord de l’Europe. La maladie s’est rapidement développée et au 1er février 2007, on recensait 2137 foyers de FCO, toutes espèces de ruminants confondues. Globalement, la maladie a affecté davantage les bovins (54 %) que les ovins (46 %). Les signes cliniques le plus fréquemment observés chez les bovins étaient des lésions sur le museau et la cavité buccale (ulcérations/croûtes), de la salivation et des boiteries chez des animaux adultes. La morbidité et la mortalité animales étaient respectivement de maximum 5 % et 1 %. Les principaux signes cliniques rencontrés chez le mouton étaient également des lésions sur le museau et la cavité buccale (ulcérations/croûtes), de l’amaigrissement et des boiteries. La morbidité et la mortalité animales étaient respectivement de maximum 12 % et 6 %. Les signes cliniques n’étant pas pathognomoniques et le diagnostic différentiel relativement vaste, seul un examen de laboratoire permet de poser un diagnostic de certitude. [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 ▲]
