Mechanical Nociceptive Threshold, Tissue Alterations and Horn Growth in Calves after Injection of Isoeugenol or Clove Oil under the Horn Bud.

Disbudding of calves is a common, painful intervention. Due to cytotoxic and anesthetic properties, the injection of clove oil or its component isoeugenol may be less detrimental to animal welfare. We investigated mechanical nociceptive threshold (MNT), possible tissue alterations and horn growth for up to 12 weeks after injection of 1.

Nociceptive Threshold of Calves and Goat Kids Undergoing Injection of Clove Oil or Isoeugenol for Disbudding.

In this preliminary study, we compared changes in mechanical nociceptive thresholds (MNT) of calves and goat kids injected with clove oil or isoeugenol under the horn bud as a potential, more welfare-friendly alternative to hot-iron disbudding. Twenty male calves and goat kids were randomly allocated to clove oil (n = 10 per species) or isoeugenol (n = 10 per species) injection under the horn buds. MNT was measured via a pressure algometer in calves and kids at several locations around the horn buds at several time points before and up to 24 h after injection.

Sinonasal cysts causing dyspnoea in two cattle - case report.

Two cattle were referred to the University Clinic for Ruminants of the University of Veterinary Medicine in Vienna. The main clinical sign in both cattle was dyspnoea with nasal stridor. Clinical examination of the upper respiratory tract was conducted, supplemented by ultrasonography, endoscopy and radiography.

[The occurrence of "Candidatus Mycoplasma haemolamae" infections in clinically asymptomatic South American Camelids in Austria].

Reports of CMhl infections in South American Camelids in Europe are only available from the United Kingdom and Switzerland. Knowing that CMhl infections can lead to severe disease resulting in death if combined with other diseases or stress, it was the aim of this study to assess prevalence data from camelids in Austria. In comparison to the previous studies a representative number of camelids was investigated nationwide.
