Abstract: 
Postpartum dysgalactia syndrome (PDS) is an economically important condition in sows. Thesyndrome is characterized by a reduced milk and colostrum production within 12 to 48 hourspost partum. The objective of this study was to determine whether preventive treatment withketoprofen (Ketofen®10%, Merial, Belgium) has a positive effect on the subclinical form of PDS.Sows (n = 39) were randomly divided into two groups: one served as control group whereas theother was treated intramuscularly with ketoprofen within twelve hours after parturition.During the first 24 hours postpartum, the rectal temperature of the sows decreased (-0.43 ±0.13 °C) in the ketoprofen group. In the control group, an increase was seen (+0.07 ± 0.02 °C)(P < 0.05). There was no significant effect on back fat loss of the sows, weight gain of the piglets(n = 541) and survival rate.In conclusion, a single intramuscular administration of ketoprofen to sows shortly afterfarrowing decreased rectal temperature but did not improve the performance of the piglets.

Title: 
Equine BNP measurement using a porcine BNP enzyme-linked immunoassay: a pilot study
Author(s): 
N. VAN DER VEKENS, A. DECLOEDT., D. DE CLERCQ, S. VEN, G. VAN LOON
Abstract: 
Brain natriuretic peptide (BNP) is used in human medicine for the diagnosis of congestiveheart failure. Since BNP is species-specific and no equine assay is available, BNP has never beendetermined in horses. Because there is more than 90% homology between porcine and equineBNP, a porcine BNP enzyme-linked immunoassay (ELISA) was used in the present study tomeasure BNP in plasma of healthy horses (group 1; n=20), horses with cardiac disease without(group 2a; n=8) and with atrial dilatation (n=8), ventricular dilatation (n=1) or both (n=1) (group2b; n=10). Samples were stored at -20°C and -80°C to study the influence of storage temperature.No significant differences were found between the BNP concentrations of group 1 (77.79; 37.20-513.36 pg/mL), group 2a (52.02; 24.69-268.37 pg/mL) or 2b (94.73; 42.88-470.66 pg/mL). Samplesstored at -80°C showed significantly (72.19, 24.69-513.36 pg/mL; P=0.001) higher concentrationsthan samples stored at -20°C (47.35, 24.69-430.60 pg/mL). In this pilot study, it is suggested thatthe porcine BNP assay does not allow accurate detection of equine BNP. An equine specific BNPassay should be developed to study BNP concentrations in horses.

Penetrating solar wounds to the foot: benefit of MRI in treatment decisions
Author(s): 
N. DE HEER, E. COMPAGNIE, F. TER BRAAKE
Abstract: 
Penetrating injuries to the sole of the hoof are common in horses. Prognosis and treatmentdepend on the structures involved. In this report, nine horses are described with a penetratinginjury to the sole of the hoof that then underwent magnetic resonance imaging (MRI) examination.The radiographic examination performed in seven of these horses provided information about thebone involvement and an MRI examination was performed in all cases to obtain information aboutthe affected soft tissues. MRI has excellent soft tissue contrast and can provide detailed images inany anatomical plane. For all nine horses, the MRI examination provided a clear guidance towardprognosis and a treatment plan. For two of the horses, the MRI examination confirmed that onlysuperficial debridement was required. In seven of the horses, the MRI findings indicated that amore invasive approach was needed, such as navicular bursoscopy or street-nail procedure.This study illustrates that an MRI examination can provide useful additional informationleading to an appropriate therapy and prognosis, and shows a good correspondence between MRIobservations and surgical findings.

Author(s): 
J. HUYGHE, V. MEGANCK, M. VAN EETVELDE, G. OPSOMER
Abstract: 
In the present study, the effect was investigated of administering an oral electrolyte solution(Glutellac®) to newborn Belgian blue calves on their vitality, the acid-balance in the blood, andtheir passive immunity. Twenty newborn calves were incorporated in the study, of which ten wereadministered a placebo and ten were administered Glutellac®. Only three calves showed metabolicacidosis. The group, which was administered Glutellac®, showed a significant higher base excess at twohours (p < 0.05), six hours (p < 0.001) and twelve hours (p < 0.001) after birth. Clinically and in termsof IgG absorption capacity, there were no significant differences between both groups. In conclusion,it can be stated that the administration of Glutellac® to Belgian blue calves without metabolic acidosisimmediately following birth by caesarean section beneficially influences the base excess.

Title: 
Effect of propofol anesthesia on ultrasonographic measurements of the adrenal glands of healthy cats
Author(s): 
A. COMBES, E. VANDERMEULEN, L. DUCHATEAU, K. PEREMANS, M. HESTA, J.H. SAUNDERS
Abstract: 
Although real-time ultrasonography is feasible in awake cats, cats are frequently anesthetizedwith propofol, if they are uncooperative or during perioperative ultrasonographic examinations.Propofol induces hypotension in cats and may cause venous vasodilation that redistributesblood volume in abdominal organs and organomegaly. In this paper, ultrasonographic adrenalmeasurements are compared before and during intravenous propofol anesthesia in healthycats. No significant effect of propofol anesthesia on adrenal size was found, and the observeddifferences were small and clinically irrelevant. Therefore, it can be concluded that propofolanesthesia does not prevent ultrasonographic diagnosis of adrenomegaly.

Title: 
Insect bite hypersensitivity in Belgian warmblood horses: prevalence and risk factors
Author(s): 
L.M. PEETERS, S. JANSSENS, A. COUSSÉ, N. BUYS
Abstract: 
Insect bite hypersensitivity (IBH) is an allergic reaction to the bites of certain Culicoides spp.or other insects. In this study, risk factors for IBH in Belgian warmblood horses stabled or grazingin Flanders (Belgium) were investigated. IBH records (n=3409) were collected in 2009 and2011 using a questionnaire and face-to-face interviews. The classification of IBH-affected versusunaffected horses was based on the owner’s statement, and the reported IBH lifetime prevalencewas 10%. Thirty eight percent of IBH affected horses had no clinical symptoms at the time ofquestioning. When only the presence or absence of clinical symptoms at the time of questioningwas taken into account, the prevalence of IBH symptoms was 6.2%. Seventy percent of IBH-affectedhorses were treated with IBH measures to reduce clinical symptoms. Model selection wasbased on backwards elimination in a logistic regression framework starting with 17 factors. Theage of the horse, vegetation of surrounding pasture and stud size were found to be significantlyassociated with the self-reported IBH status.

Abstract: 
Chlamydia (C.) abortus enzootic abortion still remains the most common cause of reproductive failure in sheep-breeding countries all over the world. Chlamydia abortus in cattle is predominantly associated with genital tract disease and mastitis. In this study, Belgian sheep (n=958), goats (n=48) and cattle (n=1849) were examined, using the ID ScreenTM Chlamydia abortus indirect multi-species antibody ELISA. In the sheep, the highest prevalence rate was found in Limburg (4.05%). The animals of Antwerp, Brabant and Liège tested negative. The prevalence in the remaining five regions was low (0.24% to 2.74%). Of the nine goat herds, only one herd in Luxembourg was seropositive. In cattle, the highest prevalence rate was found in Walloon Brabant (4.23%). The animals of Limburg and Namur tested negative. The prevalence rate in the remaining seven regions ranged between 0.39% and 4.02%.

Author(s): 
V.J.F. Van Loon, T.J. van den Brink, J.P.A.M. Van Loon, C.J.W. Scheffer, H.J. Bergman
Abstract: 
In de voorliggende studie werd de kwaliteit van de inductie en de recovery vergeleken bij 146paarden na totale intraveneuze anesthesie met guaifenesine, ketamine en detomidine, ten behoeve vancomputertomografie (CT). Ze werden willekeurig ingedeeld, waarbij de ene groep romifidine (n=110)en de andere groep detomidine (n=36) als premedicatie kreeg. De anesthesie werd geïnduceerd meteen combinatie van ketamine/midazolam. De gemiddelde anesthesieduur van de CT was kort (gemiddeld+/- SD: 23,5 +/- 8,8 minuten). Er bleek geen significant verschil te zijn voor de inductiescore. Welbleken paarden gepremediceerd met romifidine een significant betere recoveryscore te hebben.

Abstract: 
Chronic progressive lymphedema (CPL) is a well-known problem in the Belgian draft horse.However, tools for clinical diagnosis have not been standardized. Therefore, the exact diseaseprevalence and the possible CPL risk factors have not been investigated in the Belgian breedyet. The aim of the present study was to assess a uniform CPL clinical examination method toincrease diagnostic objectivity as well as to determine the occurrence and severity of lesions.Using univariate and stepwise multivariable logistic regression models, the association of factors,such as age-gender interaction, coat color and season, with CPL occurrence was examined. In thisstudy, it was demonstrated that CPL is highly prevalent in the Belgian draft horse: 60.66% of thehorses of the total sample were affected, including a large proportion of young horses (< 3 years),whereas 85.86% was affected in a subset of older horses (≥ 3 years). In the latter, the lesions weremore explicit as CPL is a chronic disorder. In some horses (i.e. 14% of the yearlings), mild clinicalsymptoms appeared at approximately the age of one, while distinct onset of the disease occurredfrom the age of three onwards. The factors age-gender interaction, coat color and season, whichare significantly associated with CPL occurrence, were identified and quantified. In this study,a standardized diagnostic protocol is proposed that will enhance future data collection andfurthermore will offer a foundation for quantitative genetic research. Ultimately, it will help toreduce CPL occurrence in the Belgian draft horse by means of selection.

Author(s): 
J. Van den hof, J. Beek, K. Chiers, D. Maes
Abstract: 
In this study, the incidence of auricular hematomas in weaned piglets was examined, and it wasinvestigated whether the incidence was linked with certain risk factors. In total, five successive batchesof weaned pigs (n=10,657) were investigated from weaning (three weeks of age) until the end of thenursery period (ten weeks of age). The mean incidence was 2.3%, ranging from 1.3% to 2.9% for thedifferent weaned batches. The incidence in barrows was 2.1% and in female piglets 2.5% (P > 0.05).The incidence in piglets from primiparous sows was 0.92% and in piglets of multiparous sows 2.45%(P < 0.001). The highest incidence was observed four to five weeks after weaning. There was a twotimes-higher risk to develop an auricular hematoma at the ear with the ear tag (RR=2.28 [1.74 – 2.98]).Further research, preferably in more herds, is warranted to confirm and/or explain the present resultsand to further optimize control measures.
