“…In this study no differences were found between castration methods in weaner or mature liveweights, which is consistent with other studies that have compared tension banding with other methods (mainly surgical and burdizzo) in bulls ranging from 95 kg (Stafford et al, 2002) to 400 kg (Knight et al, 2000;Fisher et al, 2001;Pang et al, 2008;Repenning et al, 2013) or more (ZoBell et al, 1993;Chase et al, 1995) during experimental periods of 4 (Rust et al, 2007) to 17 weeks (Knight et al, 2000). Inferior liveweight gains in banded compared with surgical castrates in the weeks following castration have been reported for 240 kg bulls (Fisher et al, 2001) and 360 kg bulls (Rust et al, 2007).…”

“…The time taken for all scrotums to be lost is variable between studies, and is reported as 5 (Chase et al, 1995), 6 (this study, mature bulls), 7 (this study, weaners), 8 (Knight et al, 2000;Fisher et al, 2001), 9 (Knight et al, 2000) and 12 (Pang et al, 2008) weeks post-castration. From the limited information provided in these studies, the variability does not appear to be correlated with liveweight, initial scrotal size or genotype.…”

“…We anticipated no difference between the two castration methods given that previous studies comparing tension banding and other castration methods (mainly surgical and burdizzo) have produced mostly consistent findings of no differences in liveweight or average daily gains in bulls (e.g. ZoBell et al, 1993;Chase et al, 1995;Knight et al, 2000;Fisher et al, 2001;Stafford et al, 2002;Pang et al, 2008;Repenning et al, 2013).…”

a b s t r a c tTension banding castration of cattle is gaining favour because it is relatively simple to perform and is promoted by retailers of the banders as a humane castration method. Two experiments were conducted, under tropical conditions using Bos indicus bulls comparing tension banding (Band) and surgical (Surgical) castration of weaner (7-10 months old) and mature (22-25 months old) bulls with and without pain management (NSAID (ketoprofen) or saline injected intramuscularly immediately prior to castration). Welfare outcomes were assessed using a range of measures; this paper reports on some physiological, morbidity and productivity-related responses to augment the behavioural responses reported in an accompanying paper. Blood samples were taken on the day of castration (day 0) at the time of restraint (0 min) and 30 min (weaners) or 40 min (mature bulls), 2 h, and 7 h; and days 1, 2, 3, 7, 14, 21 and 28 post-castration. Plasmas from day 0 were assayed for cortisol, creatine kinase, total protein and packed cell volume. Plasmas from the other samples were assayed for cortisol and haptoglobin (plus the 0 min sample). Liveweights were recorded approximately weekly to 6 weeks and at 2 and 3 months post-castration. Castration sites were checked at these same times to 2 months post-castration to score the extent of healing and presence of sepsis. Cortisol concentrations (mean ± s.e. nmol/L) were significantly (P < 0.05) higher in the Band (67 ± 4.5) compared with Surgical weaners (42 ± 4.5) at 2 h post-castration, but at 24 h post-castration were greater in the Surgical (43 ± 3.2) compared with the Band weaners (30 ± 3.2). The main effect of ketoprofen was on the cortisol concentrations of the mature Surgical bulls; concentrations were significantly reduced at 40 min (47 ± 7.2 vs. 71 ± 7.2 nmol/L for saline) and 2 h post-castration (24 ± 7.2, vs. 87 ± 7.2 nmol/L for saline). Ketoprofen, however, had no effect on the Band mature bulls, with their cortisol concentrations averaging 54 ± 5.1 nmol/L at 40 min and 92 ± 5.1 nmol/L at 2 h. Cortisol concentrations were also significantly elevated in the Band (83 ± 3.0 nmol/L) compared with Surgical mature bulls (57 ± 3.0 nmol/L) at weeks 2-4 post-castration. The timing of this * Corresponding author. Tel.: +61 (0)7 4936 0331; fax: +61 (0)7 4936 elevation coincided with significantly elevated haptoglobin concentrations (mg/mL) in the Band bulls (2.97 ± 0.102 for mature bulls and 1.71 ± 0.025 for weaners, vs. 2.10 ± 0.102 and 1.45 ± 0.025 respectively for the Surgical treatment) and evidence of slow wound healing and sepsis in both the weaner (0.81 ± 0.089 not healed at week 4 for Band, 0.13 ± 0.078 for Surgical) and mature bulls (0.81 ± 0.090 at week 4 for Band, 0.38 ± 0.104 for Surgical). Overall, liveweight gains of both age groups were not affected by castration method. The findings of acute pain, chronic inflammation and possibly chronic pain in the mature bulls at least, together with poor wound healing in the Band bulls support behavioural findings reported in...

“…Conversely, Ting et al (2005) observed increased haptoglobin concentrations in Burdizzo-castrated calves at 2.5 and 3.5 months of age during the first 7 days following castration, thereafter levels returned to baseline values. An increase in haptoglobin after Burdizzo castration was also reported by Pang et al (2008) during the first 3 days after the treatment.…”

“…Castration by the Burdizzo method is frequently used in various countries (Stafford et al, 2000;Boesch et al, 2006;Coetzee et al, 2010). During the first days after castration, a swelling of the scrotum is reported independent of the age of the calves at castration (Molony et al, 1995;Ting et al, 2005;Pang et al, 2008).…”

The objectives of this study were to evaluate the effects of Burdizzo castration and abrupt weaning on the behaviour, blood traits and performance of beef calves when weaning was conducted concurrently or consecutively to castration. In total, 64 male beef calves aged between 6 and 7 months were assigned to a 2 × 2 factorial design with the following treatment groups (n = 16 animals per treatment): (1) castrated and concurrently weaned in week 0 (CAS-WEA); (2) castrated in week 0 and weaned in week 4 (CAS-CON); (3) bulls weaned in week 0 (BUL-WEA); and (4) bulls weaned in week 4 (BUL-CON). The behaviour of the calves was observed for 3 days following weaning. Blood was collected weekly from weeks 0 to 5 and analysed for the acute-phase protein haptoglobin, and neutrophil and lymphocyte percentages. BW was recorded weekly from weeks 0 to 7. Animals were slaughtered at 17 months and weight, dressing percentage and carcass classifications were recorded. On day 1 after weaning, the number of vocalizations (calls/10 min) was higher in BUL-WEA (7.2) and CAS-WEA (5.4) than in calves of CAS-CON (2.8) and BUL-CON (2.9) groups (P < 0.05). From days 1 to 3 vocalizations decreased in all groups. CAS-CON and BUL-CON animals spent 20% lying on day 1 after weaning compared with 40% in CAS-WEA and BUL-WEA calves (P < 0.05). The haptoglobin concentration decreased during the first 5 weeks after weaning in all groups independent of the castration, weaning group or its interaction (P > 0.05). WEA groups showed an increased average daily gain (ADG) during weeks 0 to 3 and a reduced ADG during 4 to 7 weeks in comparison with CON animals. At slaughter, bulls were about 80 kg heavier than castrates and had a superior dressing percentage and carcass classification (P > 0.05). In conclusion, weaning had a greater effect on the number of vocalizations, standing/walking and lying behaviour and ADG compared with Burdizzo castration. In comparison with undertaking the procedures separately, concurrent castration and weaning neither affected behaviour and haematological parameters nor impaired performance. There was no evidence that the concurrent application of both treatments markedly increased the stress response compared with their application at intervals of a few weeks.
