This study evaluated the effects of ketamine-xylazine (KX) and alfaxalone-xylazine (AX) administered via blow darts to nine muntjacs. Induction and recovery times as well as the quality were assessed by a blinded observer. Peripheral oxygen saturation (SpO₂), heart rate, respiratory rate, and rectal temperature were recorded for at least 30 min. Tolazoline (4 mg/kg) was used post-procedure to reverse xylazine's effects. The mean doses were 4.68 ± 2.18 mg/kg for ketamine and 3.22 ± 1.33 mg/kg for xylazine in the KX group. In the AX group, the mean doses were 4.38 ± 0.31 mg/kg for alfaxalone and 1.19 ± 0.26 mg/kg for xylazine. The median induction times were 339.5 s (range 180.0-375.0) for KX and 125.0 s (range 71.0-334.0) for AX, with both groups scoring 3.0 for induction quality. The recovery times were 507.5 s (range 266.0-1081.0) for KX and 243.0 s (range 92.0-480.0) for AX, with recovery scores of 2.3 and 3.0, respectively, showing no significant difference.

This commentary argues for critical programme change in three overarching themes relevant to the Irish bTB eradication programme, if eradication is to be successful: (1) Limiting infection in cattle. Residual (hidden) infection is an important constraint to eradication, due to the use of imperfect diagnostic tests. This is resolved with a risk-based approach, as is widely used in other national programmes, and would impact herd management, cattle trade and regionalisation. (2) Limiting infection within and from wildlife. Infection in wildlife is a key feature of bTB in many countries, including Ireland. Early research with badger vaccination has been promising. However, wide-scale badger vaccination has proved logistically challenging, and research to monitor progress is underway. It is unlikely that badger vaccination, in addition to current cattle controls, will be sufficient to achieve bTB eradication. (3) Programme leadership, management, governance and cost-sharing. There are a number of substantial, seemingly intractable, issues relating to programme leadership, management, governance and cost-sharing which alone are sufficient to preclude any sustained move to eradication. International examples of success are available, with funding models being critical to progress. In these three themes, most of the constraints are non-technical. If difficult decisions are not taken and the status quo is allowed to continue, there is a risk that infection may establish in further wildlife species, which may make eradication unattainable.

Moreover, the paramphistomid species affecting sheep in the area have never been molecularly identified. To evaluate the prevalence of paramphistomid infections in sheep from northwestern Spain, 826 faecal samples from 25 sheep farms were collected and analysed via coproscopic techniques.
