Abstract

Ziel der Studie war eine Analyse der Häufigkeit und des Ausprägungsgrades tierschutzrelevanter Veränderungen bei Puten, die gemäß den Bedingungen der EU-Verordnung 889/2008 für den ökologischen Landbau gehalten wurden. In zwei Durchgängen wurden in neun Aufzucht- und 14 Mastbetrieben 32 Herden mit insgesamt 105.483 Tieren erfasst. Der Tiergesundheitsstatus der einzelnen Herden wurde stichprobenartig an fünf Zeitpunkten durch Beurteilung von 60 Einzeltieren dokumentiert. Bei jedem Bestandsbesuch wurden außerdem Einstreuproben entnommen und ihr Feuchtigkeitsgehalt thermogravimetrisch bestimmt. Die mittlere kumulierte Verlustrate in der Aufzuchtphase lag bei 3,3 % und in der 16. Lebenswoche bei 4,5%. Am Ende der Aufzuchtphase wiesen bis zu 44 % der untersuchten Tiere Epithelnekrosen an den Fußballen auf. Häufigkeit und Schweregrad von Ballenveränderungen nahmen im Verlauf der Mastphase weiter zu. So wurden in der 16. Lebenswoche bei über 80 % der untersuchten Puten Ballennekrosen festgestellt. Am Schlachthof erfolgte eine Aufnahme allgemeiner Daten zur Schlachtung und folgend die visuelle Beschau von 60 Puten je Herde. Der überwiegende Teil der Tiere (97,7%) wies zum Zeitpunkt der Schlachtung Veränderungen der Fußballen auf, während Brusthautveränderungen nur selten dokumentiert wurden. Vermehrt traten weiterhin Leberveränderungen, insbesondere Grünfärbungen auf, wobei deutliche Unterschiede zwischen verschiedenen Betrieben sowie zwischen den einzelnen Durchgängen festgestellt wurden. Auch Gelenksveränderungen waren häufige Befunde. Als ein maßgeblicher Faktor für die Gesunderhaltung eines Putenbestandes ist die Befähigung des bestandsbetreuenden Personenkreises anzusehen, gesundheitliche Probleme frühzeitig zu erkennen und zeitnah darauf zu reagieren. Neben der Qualität des Einstreusubstrates inklusive Beurteilung der Kotkonsistenz können Häufigkeit und Ausprägung von Ballenveränderungen wertvolle Hinweise für eine Einschätzung des Tierhaltungsstandards in einem Bestand liefern und sind als wichtige, einfach erfassbare Tierschutzindikatoren einzustufen . Auch Gelenks- und Leberveränderungen sind aufgrund hoher Prävalenzen als relevante Tiergesundheitsparameter zu betrachten, die im Rahmen eines Monitorings routinemäßig erfasst werden sollten.

Abstract

Summary Cholecystokinin (CCK) produced in the mucosa of the upper small intestine exerts several biological functions. Its secretion in physiological amounts is modulated by the interaction of extracellular regulators and by binding to intracellular receptors of the target cells. The relative affinity of CCK to its receptor has been characterized in various biological and pharmacological studies and it is now well established that CCK has a higher affinity to the CCKA than to the CCKB receptor. Furthermore CCK influences the secretion of pancreatic enzymes in several species but very little is known about the relationship between CCK and the islet hormone-producing cells in the pig pancreas. The localization of this receptor at the cellular level showed conflicting results in animal studies and has not been described in pigs. The aim of the present study was to characterize the precise cellular location of the CCKA receptor in the porcine pancreas. Polyclonal antiserum was raised against the N-terminal epitope of the CCKA receptor molecule and used for localization studies. Using immunohistochemistry on methanol/acetic acid-fixed, paraffin-embedded pancreas, the CCKA receptor could successfully be localized in islet cells. Parallel staining of serial sections with antibodies directed against insulin and glucagon revealed colocalization with glucagon in alpha cells. No immunoreaction was found in the exocrine pancreas. Our results support the concept that in the porcine species the stimulation of the exocrine pancreas is mediated by the CCKB rather than the CCKA receptor, as it is known for the rat species.

39. Inappropriately rough play behaviour and predatory attacks against people by a tomcat. A case report

Author

Morber, M., Bartels, A., and Erhard, M. H.

Abstract

The owner of a 6-months-old tomcat came to seek help because the cat had attacked her face on a near-daily basis. Through a detailed behavioural history, the cat’s behaviour was diagnosed as human- directed predatory attack behaviour, play-related aggression and reduced motor as well as emotional self-control. Within a few weeks, behavioural therapy produced a significant improvement. After 5 months of therapy, the cat showed neither predatory attacks nor inappropriately rough or aggressive behaviour in play towards its owner or other humans.

42. Behaviour therapy in the practice management of a veterinary practice. Survey among practicing veterinarians and veterinarians specialized in behaviour therapy.

Author

Sprauer, S., Döring, D., Herb, I., Küchenhoff, H., and Erhard, M. H.

Abstract

Objective of the study was to investigate whether behaviour therapy may be an economic niche within practice management. Material and methods: A questionnaire was used to analyze to what extent veterinarians have already applied behaviour therapy (BT) and how they evaluate economic efficiency and patient owners’ attitude. The descriptive analysis included the data from 312 practicing veterinarians (167 randomly selected, interviewed and 145 signed on for training sessions, veterinarians) and of 23 veterinarians specialized in BT. Results: Two-thirds (67% of n=288) of the practicing veterinarians offered BT in their practices. The economic efficiency of BT was evaluated as positive by 64% (of n=281) of the practicing veterinarians and by 83% (of n=23) of specialists. 32% (of n = 146) of practitioners who offered behavioural therapy confirmed an increase in sales through the application of BT. Among the specialists, 84% (of n=19) confirmed this experience. In comparison to the specialists and literature data, most of the practicing veterinarians spent insufficient time (61% of n=180) for a behaviour consultation. Furthermore, most of them (86% of n=162) charged less for BT than the amounts fixed by the German Payment Regulations (Gebührenordnung für Tierärzte), as compared to the specialists. Conclusion: The specialized veterinarians offered, in contrast to most practitioners, a consultation of BT with sufficiently calculated time and accurate payment planning to realise a therapeutic and commercial outcome. Therefore, the assessment of the economic efficiency of BT and their sales increase through BT were better than the estimation of the practicing veterinarians. Behaviour therapy cannot be managed by providing advice free of charge or charging less. Veterinarians have to become aware that BT is a veterinary area of specialization for which an adequate qualification is necessary. If the veterinarian is not specialized in BT he should refer to a qualified colleague.

43. Investigation on the immunoglobulin G (IgG) levels in newborn piglets by use of three different ELISA tests

Author

Pausenberger, A., Schuster, K., and Erhard, M. H.

Abstract

Objective of the study was to evaluate whether the Colostrum Quality Counter (CQC), a new test method for immunoglobulin G (IgG) levels in newborn piglets, is easy to handle and provides comparable results to established testing regimes. Material and methods: Blood samples from 219 piglets from four different farms were tested for their IgG-concentrations using three different ELISA tests. Furthermore, double samples from 30 piglets were taken from both the anterior vena cava and from the tail to determine whether the collection site affects the results. The three tests used were the Colostrum Quality Counter (CQC; FarmulaONE, NL-Best), the internal IgG-ELISA from our laboratory (MUC) and a commercially-available IgG-ELISA (NAT; NatuTec, Frankfurt/Main, Germany). Results: MUC and NAT showed a higher correlation to each other than to the CQC when referring to the individual results per single piglet. The results from the CQC were higher and the standard deviation was significantly greater. The sampling site had no significant effect on the IgG concentrations measured. Clinical relevance: The CQC is a straightforward and simple test, being very convenient for sampling a large number of piglets. CQC results were inhomogeneous with some unusually high IgG-concentrations. MUC and NAT provided comparable results to one another and the IgG-concentrations showed a good correlation.

Abstract

Prophylactic effect of specific egg yolk antibodies in diarrhea of weaned piglets caused by Escherichia coli K88 (F4) In this study, the protective effect of specific egg yolk antibodies on diarrhea caused by Escherichia coli K88 (F4) was investigated with 179 weaning piglets in a double-blind field trial. The piglets were divided into three groups. The antibody group received egg powder with specific antibodies to E. coli K88, K99, 987P, and rotavirus, while one control group was fed with egg powder without specific antibodies and a second control group received no egg powder at all. The piglets were fed ad libitum. The egg powder was offered in a 5% feed ration. Compared with the control groups, the piglets of the antibody group showed significant differences (P < 0.05, X2-test) in the parameters rate of diarrhea (17.2%) (antibody group) to 60.7% (control egg group) or 56.7% (control group without egg powder), severity of symptoms (5.2-39.3% or 26.7%) and frequency of additional treatments (8.6-55.7% or 51.7%). Because of the additional treatments, no difference could be found in body-weight gain. In control groups, three piglets died, while no pigs died in the antibody group. Zusammenfassung In der vorliegenden Arbeit wurde bei 179 Absatzferkeln die prophylaktische Wirkung von spezifischen Dotterantikörpern auf Escherichia coli K88-bedingte Durchfallerkrankungen in einem Doppelblindversuch überprüft. Die Absatzferkel wurden in drei Gruppen eingeteilt. Die Ak-Pulver-Gruppe erhielt Volleipulver mit spezifischen Antikörpern gegen E. coli K88, K99 und 987P sowie Rotaviren, während eine Kontrollgruppe Volleipulver ohne spezifische Antikörper (Ko-Pulver-Gruppe) und eine weitere Kontrollgruppe (Kontroll-Gruppe) kein Eipulver bekam. Die Eipulver wurden jeweils in einer 5%igen Zumischung den Ferkeln ad libitum angeboten. Im Vergleich zu den Kontrollgruppen zeigten die Ferkel der Ak-Pulver-Gruppe signifikante Unterschiede (P < 0,05, X2-Test) bei den Parametern Durchfallinzidenz (17,2% (Ak-Pulver-Gruppe) zu 60,7% (Ko-Pulver-Gruppe) bzw. 56,7% (Kontroll-Gruppe), Auftreten von Störungen des Allgemeinbefindens (5,2-39,3% bzw. 26,7%) und Anzahl der zusätzlich notwendigen Therapiemaßnahmen (8,6-55,7% bzw. 51,7%). Aufgrund der zusätzlichen Behandlungen war die Körpergewichtsentwicklung unbeeinflußt. In den Kontrollgruppen starben drei Ferkel, während in der Antikörper-Gruppe keine Verluste zu verzeichnen waren. [ABSTRACT FROM AUTHOR]
