Summary

Objective: Description of clinical, biochemical and haematological changes in Saanen goat kids post-exposure to a naturally occurring heat stroke. Material and methods: The experimental group consisted of goats of different age (1–4 months) and sex (8 males, 12 females) with an average weight of 7.2 ± 3.1 kg. Twenty clinically healthy, three to four months old, Saanen goat kids (sex-ratio 1:1) were used as a control. The average body weight in this group was 9.4 ± 2.6 kg. Case history, clinical signs, and results of haematology and blood biochemistry were documented in all goat kids. Results: Most common findings were hyperthermia, ataxia, muscle tremor and depression. Increased serum urea, creatinine, potassium and plasma lactate concentrations as well as an increase in aspartate aminotransferase and lactate dehydrogenase activity were observed in goats post-exposure to heat stroke when compared to the control group. Two goat kids died despite supportive treatment. Physical and biochemical blood parameters improved following treatment. Conclusion: This is the first study on heat stroke in Saanen goat kids. Heatstroke may be fatal in Saanen goat kids, despite appropriate treatment, and may lead to secondary complications. Plasma lactate concentration seems to be a reliable indicator for the prognosis of heat stroke in goat kids.

Zusammenfassung

Gegenstand und Ziel: Beschreibung der klinischen, biochemischen und hämatologischen Veränderungen bei Saanen-Ziegenlämmern nach natürlich auftretendem Hitzschlag. Material und Methoden: Bei 20 Ziegenlämmern, bei denen unter natürlichen Bedingungen ein Hitzschlag auftrat, wurden neben Vorbericht und klinischen Symptomen die Ergebnisse hämatologischer und biochemischer Blutuntersuchungen erfasst und den Werten von Kontrolltieren gegenübergestellt. Die von einem Hitzschlag betroffenen Ziegenlämmer (1–4 Monate, 8 männlich, 12 weiblich) hatten ein Durchschnittsgewicht von 7,2 ± 3,1 kg. Die Kontrollgruppe bestand aus 20 gesunden Ziegenlämmern (3–4 Monate, 10 männlich, 10 weiblich) mit einem Körpergewicht von 9,4 ± 2,6 kg. Ergebnisse: Die wichtigsten klinischen Symptome der von einem Hitzschlag betroffenen Tiere waren Hyperthermie, Ataxie, Inkoordination, Muskelzittern und Depression. Im Vergleich zu den Kontrolltieren wiesen sie erhöhte Serumharnstoff-, -kreatinin-, -kalium- und Plasmalaktatkonzentrationen sowie erhöhte AST- und LDH-Aktivitäten auf. Zwei Ziegenlämmer starben trotz Behandlung. Bei den überlebenden Tieren führte die Therapie zu einer deutlichen Besserung der klinischen Symptomatik und der biochemischen Parameter. Schlussfolgerung: Dies ist die erste Studie, die die Auswirkung eines Hitzschlags bei Saanen- Ziegenlämmern beschreibt. Die Bestimmung der Laktatkonzentration im Plasma scheint ein wertvoller Indikator für die Prognose zu sein.
