Changing moral and ethical considerations have led to societal demands for better agricultural practices and enhanced wellbeing for food producing animals all around the world. In this perspective, proper pain management is a critical component of promoting farm animal welfare. Pain alters behavior, autonomic, and neuroendocrine function. It causes a depressed mood and is a common cause of animal welfare violations (Steagall et al., 2021). In farm animals, chronic pain, for example, was shown to reduce food consumption and average daily weight gain, raises heart rate and blood pressure, and lowers body temperature (Stewart et al., 2010).Sheep are subjected to various husbandry operations such as castration, vasectomy, and tail docking, and are prone to developing painful pathologies such as lameness, mastitis, vaginal prolapse, and penis deviation. Moreover, sheep are also widely employed as an experimental animal model for particularly invasive surgeries (Coulter et al., 2009), for educational purposes, and biological research (Lizarraga & Chambers, 2012).
