    Survey of husbandry practices and captive environments for North Island brown kiwi (Apteryx mantelli) housed in facilities within and outside New Zealand
    (Cambridge University Press on behalf of The Universities Federation for Animal Welfare, 2025-06-20) Connor RL; Ling N; Beausoleil NJ; Descovich K; Jenkinson T
    North Island brown kiwi (Apteryx mantelli), endemic to New Zealand (NZ), are held in captivity both within and outside of NZ. However, more knowledge is required regarding how kiwi are housed and managed. This study aimed to characterise the demographics and reported health/ behavioural issues of the captive population of kiwi, investigate current housing and husbandry practices, and explore the association between reported behavioural problems and housing practices. Between November 2021 and June 2022, all 31 facilities holding kiwi were invited to participate in a questionnaire. Thirteen facilities within NZ (92.9% response rate) and ten elsewhere in the world (58.8%) responded, covering 97 kiwi in NZ (93.3%) and 40 outside NZ (83.3%). Kiwi in NZ were younger on average than birds elsewhere. Environmental conditions, including enclosure size, temperature, and lighting, varied across facilities. Health issues were reported in 39% of kiwi and behavioural in 20%, with common behavioural issues including stereotypical or reproduction-related behaviours. Kiwi in those facilities outside of NZ were heavier and housed in smaller enclosures. Kiwi in nocturnal houses were more likely to be reported as displaying behavioural problems than off-display enclosures. A higher proportion of NZ kiwi were housed in nocturnal houses compared to elsewhere, and one in five NZ kiwi were reported as displaying a behavioural problem, compared to 1/8 in other countries. Behavioural issues in kiwi may be underreported due to their nocturnal nature, and both behavioural and health challenges could negatively impact their welfare. Further research is essential to optimise captive conditions and improve health, behaviour, and welfare outcomes for this iconic species.

    Objective measures for the assessment of post-operative pain in Bos indicus Bull calves following castration

    The aim of the study was to assess pain in Bos indicus bull calves following surgical castration. Forty-two animals were randomised to four groups: no castration (NC, n = 6); castration with pre-operative lidocaine (CL, n = 12); castration with pre-operative meloxicam (CM, n = 12); and, castration alone (C, n = 12). Bodyweight was measured regularly and pedometers provided data on activity and rest from day -7 (7 days prior to surgery) to 13. Blood was collected for the measurement of serum amyloid A (SAA), haptoglobin, fibrinogen, and iron on days 0, 3 and 6. Bodyweight and pedometry data were analysed with a mixed effect model. The blood results were analysed with repeated measure one-way analysis of variance (ANOVA). There was no treatment effect on bodyweight or activity. The duration of rest was greatest in the CM group and lowest in the C group. There was a significant increase in the concentrations of SAA, haptoglobin, and fibrinogen in all of the groups from day 0 to 3. Iron concentrations were not different at the time points it was measured. The results of this study suggest that animals rest for longer periods after the pre-operative administration of meloxicam. The other objective assessments measured in this study were not able to consistently differentiate between treatment groups.
