Future efforts will be concentrated on improving the models and, as a result, the trustworthiness of the preclinical findings. Pigs have been used in gastro-intestinal surgery for a variety of purposes, including the development of meshes for abdominal defect repair and the enhancement of surgical methods aimed at compensating functional impairments. A special application has been made in liver regeneration and transplantation procedures, which have promising future prospects, as well as in metabolic surgical research for metabolic illness interventional treatment. Pigs have mostly been used in endocrine surgery to develop pancreatic and islets transplantation for type 1 diabetes therapy, with little research on the other glands. Osteoarticular and neurosurgery are two fields where the pig is increasingly being used: for ethical reasons rather than non-human primate models in neurosurgery, and because this species' rapid growth allows for the testing of the biomechanical properties of orthopedic devices in the context of skeletal growth. In general, the pig has a current and future role in testing novel surgical equipment or bioengineering solutions, establishing new minimally invasive techniques, and training in robotic surgery, regardless of discipline. Finally, pig-to-human organ xenotransplantation poses a significant translational surgical hurdle.

One must consider several factors; one of these, of utmost importance, is the translational value of the animal model. The sheep, as a translational surgical model, possesses a multiple of advantages that makes it one of the preferred models in several research domains.</p><p><strong>Summary: </strong>Sheep are the state-of-the-art test models for cardiovascular research and safety studies required for approval of cardiovascular implantable devices; the sheep's heart size, cardiac muscle, heart valves, and the mechanical, haemodynamic, and coagulation parameters are very similar to humans. Furthermore, the pregnant sheep/lamb are robust models for studying neonatal adaptation and placental physiology due to its physiological similarities with humans. Its placental structure supports efficient gas exchange, resembling human oxygen transfer mechanisms. The ovine model is mainly used in studies of adaptation at birth, foetal physiology during labour, and congenital diaphragmatic hernia. The sheep model is also used in several orthopaedic preclinical models, mainly in the study of critical bone defects, cancellous bone healing, osteomyelitis, and joint replacement surgeries. It is also a preferred model of bone healing in osteoporosis. Moreover, the sheep has gained popularity as a model of osteoarthritis (OA); it is a validated model of surgically induced OA. Several therapeutic modalities can be evaluated using validated outcome measures such as, kinetics, kinematics, imaging, repeated arthroscopic grading, synovial fluid analysis, and biomarkers. The ovine model, because of its size, is the closest to humans for the evaluation of spinal surgery techniques, devices, and spinal fusion biological enhancers/cancellous graft replacement. Finally, we will outline the different specificities of sheep analgesia and anaesthesia. Challenges encountered in ruminant anaesthesia are mainly in relation with their digestive physiology that creates a high risk of regurgitation during anaesthesia and a hindrance of diaphragm/respiratory movements due to rumen repletion and meteorism. Fasting regimen and management of recovery should encompass strategies that limit the starving sensation and allow for reduced social isolation. Clarification of the interactions between scientific objectives and anaesthesia-analgesia protocols prevents conflicts between the ethics and the purpose of the experiment while allowing for development of model-specific anaesthesia and pain management protocols.</p><p><strong>Key messages: </strong>The sheep has become a popular model because of its size, availability, robustness, cost, and ease of handling.
