Iodine (I) and selenium (Se) deficiencies are commonly reported in cattle, however, there are also studies regarding a very high iodine supply. The aim of the study was to determine the long-term effect of I and Se supplementation on non-pregnant cows, pregnant cows and their calves. The hypothalamus pituitary axis was investigated (TSH, T4, T3 assays) during a TRH challenge on non-pregnant cows. Twenty-four cows, half of them pregnant, were assigned into 2 diet-groups, one group with a low I (0.45 ppm) and Se (0.15 ppm) diet (LISe), the other with a high I (5.45 ppm) and Se (0.45 ppm) diet (HISe), for a period of 120 days. Nutritional (plasma iodide, urinary I, plasma Se, I content in colostrum and foetal fluids) and functional (thyrotropin, thyroid hormones, glutathione-peroxidase activity in erythrocytes) markers of I and Se status were assayed in dams at regular intervals for 120 days and in their calves at birth. A TRH challenge was performed on 8 non-pregnant cows at day 110 of the trial. At the end of the study, I and Se nutritional markers were higher in dams in the HISe group, compared to the LISe group, except for plasma Se. At birth, I nutritional markers in calves in the HISe group were higher compared to the LISe group. Reactivity of the pituitary–thyroid-axis was not influenced by I and Se supplementation. I and Se supplementation is efficient in improving newborn status. [less ▲]

After ingestion of moulded beet pulp silage, cases of cerebro-cortical necrosis (CCN) and mortalities were observed in a dual purpose Belgian Blue (BB) herd. Contamination with Paecilomyces spp., a mould that produces byssochlamic acid, malformins and patulin, was proven. Twenty-five days after progressive introduction of beet pulp silage into the ration, most of the animals showed diminished appetite, excessive salivation and decreased milk production. Some of them showed anorexia, head pressing and blindness while 4 animals died within 1 week after onset of neurological symptoms. The survivors had been treated successfully with thiamine and recovered completely within five days. Once the beet pulp silage had been identified as causative agent, it was removed from the animals’ ration and no more clinical cases were observed. Silage was obviously moulded and analysis revealed the presence of 1.6 million CFU Paecilomyces spp./g of silage. Although no further investigation was undertaken to identify the mycotoxins, intoxication with patulin was suspected, since other mycotoxins produced by these species are less toxic. Although it has not been described that CCN can be induced by ingestion of Paecilomyces spp., it seems that there is a close relation between ingestion of Paecilomyces-contaminated silage and clinical signs observed in this herd.

Background: Failure of passive transfer (FPT) in beef calves can be detected by refractometry. Nevertheless, different models of refractometers are available, and few studies compare them for the detection of FPT. Objectives: To compare the accuracy of 4 different refractometers for measuring serum total protein concentrations in comparison with results obtained by the biuret method and, based on the serum IgG threshold of 1,600 mg/mL, to determine, for each refractometer, the optimal serum protein concentration’s lowest threshold for successful passive transfer. Animals: One hundred and eight healthy beef calves, 3–8 days of age. Methods: Observational study. The concentrations of serum total proteins were determined with 4 different models of refractometers and compared with the biuret method by a Bland–Altman statistical method. The optimal serum protein concentration’s lowest threshold for successful passive transfer was determined for each refractometer by receiver operating characteristic (ROC) analysis. In addition, the serum immunoglobulin G (IgG) concentration was compared with the serum gamma-glutamyl transferase (c-GT) activity and with the total immunoglobulin concentration. Results: The refractometric measurements were highly correlated with those obtained by the biuret method. Serum total protein concentration threshold values of 56, 58, 54, and 56 g/L were found respectively for the Atago, Atago ATC, Wolf ATC, and digital ATC refractometers. Immunoglobulins were highly correlated with IgG, whereas Gamma-GT only reflected colostrum uptake by the calf. Conclusions and Clinical Importance: All refractometers could be used for the assessment of passive transfer using their individual serum protein concentration threshold. [less ▲]

Background Cardiac morphologic and functional changes consistent with cardiomyopathy have been reported in field cases of calves with accidental doxycycline overdosing. The purpose of this study was to evaluate clinically the cardiac effects of an experimentally-induced doxycycline overdosing in healthy calves. Twelve 2 months-old healthy Belgian Blue calves were studied. Six of them (group 1) received the normal dose (5 mg/kg, BID) and the six others (group 2) received five times the normal dose (25 mg/kg, BID) of oral doxycycline for five consecutive days (D1 to D5). Each calf was clinically examined daily. Measurement of serum AST, CK, Iso-CKs and LDH activities and an echocardiographic examination were performed before (D0) and one day after (D6) the last doxycycline administration. An ECG tracing was recorded at D0, D4, and D6. Results In both groups, no clinical, blood, echocardiographic or electrocardiographic changes suggestive of a cardiomyopathy were observed. Only a decreased appetite was observed in the calves of the group 2 between D3 and D6. Conclusions This trial failed to reproduce cardiac changes reported in accidental doxycycline-poisoning in calves, suggesting that high doses of doxycycline may not be the only etiologic factor of the cardiomyopathy reported in the field cases.

Bovine ehrlichiosis is a tick-borne rickettsial disease caused by Anaplasma phagocytophilum. The disease can also be transmitted to humans. Outbreaks in cattle have been described in many European countries. In Belgium, infections caused by Anaplasma phagocytophilum have been reported in humans and dogs; however this paper details the first report of ehrlichiosis in cattle herds in Belgium. The first case described was in a dairy herd located in east Belgium. Clinical signs included hyperthermia, polypnea and swelling of the limbs. The other case was diagnosed in a second, mixed purpose, herd in west Belgium. Within the second herd all of the affected animals came from the same pasture. All animals in that pasture showed recurrent hyperthermia and some also showed signs of mastitis and late-term abortions. Blood smears and serology revealed the presence of Anaplasma phagocytophilum in the majority of animals with pyrexia. Furthermore, the presence of leptospirosis, Neospora caninum and Q fever antibodies was tested by serological analysis but all results were negative. Paired serology for Adenovirus, BHV-4, BHV-1, BVD, PI3 and RSV-B did not show any significant seroconversion. Milk samples from cows affected by mastitis revealed minor pathogens. Fecal testing for the presence of Dictyocaulus viviparus in the first herd was negative. Recurrent pyrexia in pastured cattle is a non-specific sign, and can be related to several different pathogens. Bovine ehrlichiosis is transmitted by the tick species Ixodes ricinus which is known to be present throughout Belgium. Belgian practitioners should include ehrlichiosis in their differential diagnosis when confronted with pastured cattle suffering from recurrent pyrexia. [less ▲]

The purpose of this study was to evaluate, under field conditions, the efficacy of an european registered bovine concentrated lactoserum (Locatim) in 3 farms with neonatal diarrhoea in calves. A total of 117 healthy Belgian Blue (BB) calves were allocated in 2 groups. Two thirds of the calves received Locatim orally immediately after birth and maternal colostrum one hour later (treated group), while control calves only received maternal colostrum. Every day during 14 days, mental status, faeces consistency, suckling reflex and hydration status of each calf were monitored. Individual blood samples were assessed for passive transfer and specific Escherichia coli antibodies against strains F5, CS31A, F17 and F41. Faecal samples from diarrheic and non diarrheic calves were analysed for rotavirus, bovine coronavirus, Cryptosporidium parvum and Escherichia coli F5. Locatim had no significant effect on the onset, duration and incidence of diarrhoea. The mean serum IgG concentration of 23.1 ± 7.8 mg/ml indicates a good IgG transfer. Only the CS31A strain titer was significantly higher in the treated group. The major identified causative agent of diarrhoea was C. parvum. In conclusion, Locatim only has a slight effect when IgG transfer is optimal, but could be justified when specific antibodies lacking in colostrum are needed [less ▲]

For several decades, the bovine was subject to various hemorrhagic syndromes which causes have historically been found. Since the mid-2000s, a new hemorrhagic syndrome seems to emerge with a significant epidemiological consistency, suggesting a common etiology, although unknown at present. The affected animals were calves of less than 30 days, of all races born to mothers without specific parity. We noticed a very sporadic disease (1/10.000) but lethal to 99%. The characteristic lesions are multifocal hemorrhages, hyperthermia, melena, we noted medullar aplasia systematically. These calves are vironegative for BTV, enzootic bovine leukosis and BVDV. No viral or bacterial agent could be isolated. It seems that most of these calves were born from dams vaccinated against BVDV. The track of an immune dysfunction is the most serious for the moment.

BACKGROUND: Reports of doxycycline-induced toxicity are limited despite common use of this antibiotic to treat infectious respiratory disorders in calves. OBJECTIVE: To describe previously unreported kidney lesions and diagnostic test results in doxycycline-overdosed calves and to compare these results with other findings reported previously. ANIMALS: Thirty-two calves that presented with adverse effects after receiving high doses of doxycycline as a treatment for mild respiratory disorders. METHOD: Retrospective review of medical records. RESULTS: Clinical examination identified mainly lethargy, dyspnea, cough, tongue paresia or paralysis associated with dysphagia and sialorrhea, tachycardia, tachypnea, and signs of myopathy. Blood analysis indicated increases in creatine kinase, lactate dehydrogenase, aspartate aminotransferase, and sorbitol dehydrogenase activities and increased serum creatinine and urea concentrations. ECG recordings and Doppler echocardiography examination identified ventricular premature beats and a decrease in left ventricular global and systolic function, respectively. Necropsy and histopathology disclosed necrosis of the myocardium, tongue, and some striated muscles, acute renal tubular necrosis, and fatty degeneration or congestion of the liver. CONCLUSIONS: Most of these findings corroborate previous observations made in doxycycline-overdosed calves, and further suggest myocardial and striated muscular toxicity as well as renal toxicity in doxycycline-overdosed calves.

For 30 years, many haemorrhagic syndromes were observed in cattle. The recent observation in Europe of a new entity hemorrhagic highlights a consistent set of clinical cases in calves of all breeds under 30 days of age, with pancytopenic haemorrhagic purpura. Calves are vironegative for BVD and BTV, most are seropositive for both viruses antibodies. No specific etiology has been highlighted, but it seems that the syndrome is linked to the ingestion of colostrum immunized against cells of the calf. The syndrome is sporadic, with a prevalence ranging between 1:10,000 and 1:100,000 cattle under one year of age, causing a lethality of 99%. The origin of the pancytopenia is a medullar aplasia.

Since the last 5 years, a specific hemorrhagic syndrome of unknown etiology was described in young calves. This disease has a low incidence but a very high mortality rate. No etiology has been found yet, though many labs have already gathered lots of cases around Europe. For example, more than 200 cases in 170 farms in Germany, 60 cases in 40 farms were described in Gent’s veterinary faculty in Belgium. In France and in the United Kingdom, several cases have been recorded yet, in multiple different locations. As far as we know, the disease concern young calves aging between 10 and 30 days, from different breeds. Most calves present a purpura on multiple sites on skin, gums, eye sclera and ears. Hematology indicates severe anemia, thrombocytopenia, neutropenia with or without leukopenia. Necropsy indicates multiple hemorrhages in serous membranes on every abdominal viscera. Alfort’s veterinary faculty has described acute necrotizing hepatitis on one case in France. Those calves are BVDV and BTV negative both on antigen tests. In Liege’s veterinary faculty one live case was examined, from a modern farm with 160 calvings, and less than 5% of calf mortality per year. The farm had 3 hemorrhagic fatal cases during July 2009, of very quick evolution. From those, 2 were autopsied and diagnosed BVDV negative. The 20 days old calf had hyperthermia in the morning, received oxytetracycline in the farm and began bleeding at noon. As many of the described cases, the calf presented mild depression with hyperthermia and tachypnoea. Skin and ear purpura, gum hematoma, melena, hematuria and hemoglobinuria were noticed. Hematology revealed a severe anemia with decreased hematocrite due to a profound thrombocytopenia (4.79*109/l). Leukocytes formula also shown neutropenia (0.10*109/l) and a monocytosis (1.32*109/l). It resulted in a mild leukopenia (3.59*109/l). We also noticed hypogammaglobulinemia (2.92 g/l and 6.8% of total protein). This calf received an immune-suppressive treatment with a high dose of dexamethasone (0.64mg/kg), and a cover antimicrobial therapy (Enrofloxacine). A good evolution of the symptoms on day 2 was observed. Leukocyte formula had a normal answer to dexamethasone concerning the lymphocytes and neutrophils population. On day 6, blood formula was already stabilized, with increasing hematocrite from 12% on day 3 to 15%. Thrombocytes count has also increased to 58.20*109/l; leukocytes count was also back to normal with normal formula. Flow cytometric measures on the lymphocytes subpopulations indicated a subnormal Gamma-Delta and Natural Killer population, and a high number of apoptotic cells 12 hours after sampling. This syndrome can be linked to idiopathic thrombocytopenia in human newborn both regarding symptomatology and treatment answer. Though this data helps in the understanding of this pathology, it concerns only one animal and needs to be confirmed through further experiment on live cases. [less ▲]

Cardiomyopathies in cattle are disorders that are sometimes encountered by rural practitioner. They usually lead to cardiac dysfunction, heart failure, arrhythmias and even sudden death. Most of cardiomyopathies in cattle are of hereditary, nutritional or toxic origin. Bovine cardiomyopathies may involve only one animal as they may affect several animals of the farm and can cause considerable economic losses either in treatment costs, decrease of zootechnical performances or in mortality. The etiological variability of cardiomyopathies as well as non-specificity of clinical signs often complicate the diagnostic approach of the practitioner. In this paper, a literature review on cardiomyopathies that may occur in cattle is proposed. Their different aetiologies and clinical aspects as well as diagnostic means in affected cattle are discussed [less ▲]

Selenium (Se), iodine (I), zinc (Zn) and copper (Cu) deficiencies in cattle have been reported in Europe. These deficiencies are often associated with diseases. The aim of the study was to assess trace element status in Belgian cattle herds showing pathologies and to compare them to healthy cattle herds. Eighty-two beef herds with pathologies, 11 healthy beef herds, 65 dairy herds with pathologies and 20 healthy dairy herds were studied during barn period. Blood and/or milk samples were taken in healthy animals. Plasma Zn, Cu, inorganic I (PII) and activity of glutathione peroxidase in erythrocytes (GPX) were assayed. In milk, I concentration was measured. Data about pathologies and nutrition in the herds were collected. According to defined thresholds, it appeared that a large proportion of deficient herds belonged to "sick" group of herds. This conclusion was supported by the mean value of trace elements and by the fact that a majority of individual values of trace elements was below the threshold. Dairy herds had mean values of trace elements higher than beef herds. More concentrates and minerals were used in healthy herds versus "sick" herds. These feed supplements were also used more often in dairy herds, compared to beef herds. Trace elements deficiencies are present in cattle herds in Belgium and are linked to diseases. Nutrition plays a major role in the trace elements status. [less ▲]

Iodine (I) deficiency is commonly reported in cattle around the world and is often associated with clinical or sub-clinical diseases. As most of clinical signs are not pathognomonic, diagnosis has to be confirmed by biochemical analyses such as plasmatic inorganic iodine (PII) or urinary I. Different oral mineral forms of I are available in Europe for cattle. The aim of the study was to compare the kinetic of I in blood and urine in non-lactating cows, following oral administration of different forms of I. Five groups of 6 non-lactating cows (aged 6 ± 2 years, weight 604 ± 89 kg), receiving the same ration (11 kg dry matter) and housed in the same conditions (tied-stall and straw) underwent a double-blinded trial during 2 months. Excepting in Group A (Control), all cows received a daily oral supplementation of I equal to 5 ppm, in the form of Ca(IO3)2 (Group B), KI (Group C), organic form of I 1 (Group D) and organic form of I 2 (Group E). Formulas of the organic forms of I are not public and coverable by patent. Supplementation was stopped at T45. Blood and urine samples were taken at T0, T15, T30 and T60. Thyroxine (T4) was measured at T0, T30 and T60 while PII and urinary I were measured at the 4 times of the trial. Student-t test and multiple comparisons of means (mix crossed model) were used to compare I and T4 concentrations between groups and times. All characteristics about the cows and I levels in blood or urine were not significantly different at T0 (p>0.1). There was no significant difference (p>0.1) between groups B, C, D, E at the different times of the trial. PII and urinary I in Group A were significantly lower than in other groups (p<0.01) at T15 and T30. Highest concentrations of I (PII up to 242 ± 30 µg/L and urinary I up to 2326 ± 439 µg/L) were reached at T15 for groups B, D and E. At T60, PII (19 ± 4 µg/L) and urinary I (110 ± 29 µg/L) of all groups reached the basal level. A good correlation was found between PII and urinary I (r² = 0.77). No significant differences were found about T4 (67 ± 10 nmol/L) in all groups and times (p>0.1). PII and urinary I are good markers to assess I nutritional status. No difference was found between either inorganic or organic forms of I, nor between them. Concerning the mineral forms of I, Ca(IO3)2 might be preferably used because of its higher stability in the mineral complexes. [less ▲]

The widespread use of elite sires by means of artificial insemination in livestock breeding leads to the frequent emergence of recessive genetic defects, which cause significant economic and animal welfare concerns. Here we show that the availability of genome-wide, high-density SNP panels, combined with the typical structure of livestock populations, markedly accelerates the positional identification of genes and mutations that cause inherited defects. We report the fine-scale mapping of five recessive disorders in cattle and the molecular basis for three of these: congenital muscular dystony (CMD) types 1 and 2 in Belgian Blue cattle and ichthyosis fetalis in Italian Chianina cattle. Identification of these causative mutations has an immediate translation into breeding practice, allowing marker assisted selection against the defects through avoidance of at-risk matings. [less ▲]

There have been few formal studies on stress in veterinary surgeons and, in the rare studies available, stress is not examined jointly through the levels of job strain and job engagement, the sources of stress in the issue of work environment and the work-home interference. The authors’ goal in this study was to analyse job engagement, job strain, burnout, work-home interference and job stress factors among 216 Belgian veterinary surgeons. Rural practice was compared to small animal and mixed activity. The mean job strain and job engagement level in veterinary surgeons was not higher than what we found in other working populations. However, 15.6 % of the group were found to be suffering from high burnout. Rural practitioners had a lower level of job engagement than small animal veterinary surgeons. These small animal practitioners had a lower level of job strain than the mixed practitioners. The level of burnout did not differ significantly across the three types of activity. In comparison to other Belgian and Dutch workers, veterinary surgeons perceived more negative workhome interference. Bovine and mixed practitioners were the most concerned with this problem. The two most important sources of stress reported by bovine practitioners were relations to farmers and working time management (including emergencies and availability). [less ▲]
