A groundbreaking new study by researchers from South Africa has provided valuable insights into the behavioural responses of lambs during and after tail-docking procedures. It offers important considerations for sheep producers balancing animal welfare with farm management practices.
The 2025 study, led by M. Teubes and colleagues A.J. Scholtz, K. Dzama, and S.W.P. Cloete, meticulously observed 228 Merino lambs to evaluate their comfort levels during this common yet controversial farming practice.
The research team employed a methodical approach to assess lamb behaviour across three critical periods: during the tail-docking procedure, immediately afterwards, and ten minutes after. Their observations revealed significant differences between docked lambs and their undocked counterparts.
“During docking, treatment lambs exhibited significantly more distress behaviours than control lambs, who were more likely to remain calm,” the authors noted in their findings. These distress indicators included increased restlessness, bleating, intense kicking, and tense facial expressions.
The researchers observed signs of discomfort persisted after the procedure, with docked lambs displaying more agitated behaviours such as tail-flicking and standing with their legs apart. However, they found “no evidence of worsening or prolonged pain” during the observation period.
This study is critical for the livestock industry, as Teubes and colleagues acknowledge: “As consumers become more welfare-conscious, the livestock industry is being increasingly pressured to reevaluate and justify routine procedures such as tail-docking.”
In their conclusion, the researchers highlight the delicate balance between short-term discomfort and long-term benefits. “Although discomfort was significant during and shortly after the procedure, the pain and unease appeared transient,” they observed. They noted that the practice helps prevent fatal conditions like breech blowfly strikes.
While not advocating for an immediate end to tail-docking, the research team emphasises the need to continue evaluating the practice in light of their findings regarding lamb discomfort.
Further research should focus on refining the procedure, exploring effective pain mitigation methods, and analysing the trade-offs between the procedure’s welfare outcomes and its ethical implications,” the authors recommend.
The study offers an evidence-based perspective on routine management practices for sheep producers and promotes the consideration of pain management strategies during tail-docking procedures.
As the agricultural industry evolves with changing consumer expectations, research such as this study by Teubes and colleagues provides critical information for developing best practices that balance animal welfare concerns with practical farm management.
This research contributes to the ongoing discussion about humane farming practices and underscores the industry’s commitment to continuous improvement through the scientific evaluation of traditional methods.
