Abstract

The amount of attention paid to the welfare of animals and their maintenance conditions has grown considerably in recent years. This paper examines the effects of extensive and intensive housing systems on the environmental, behavioural, health, nutritional and social aspects of sheep welfare. It presents the current state of knowledge regarding this welfare, and its significant contributing factors, based on a search of PubMed, Web of Science, Google Scholar and Scopus using defined keywords. It compares the impact of the two systems on the physical, psychological and social comfort of the animals, and identifies husbandry practices conducive to improving welfare. In doing so, it pays particular attention to the role of social bonding and the importance of grooming interventions. The paper reviews the factors shaping welfare in different production systems, with a particular focus on extensive and intensive rearing. It demonstrates that while the extensive system is conducive to the realisation of natural behaviour and the formation of social bonds, it can also be associated with a higher risk of nutritional deficiencies and environmental stressors. In contrast, an intensive system allows better control of health and nutrition, but often limits the ability to meet behavioural needs. The study also discusses the importance of feeding strategies, herd structure and thermal comfort, as well as the impact of routines such as shearing and hoof correction. It demonstrates that high levels of welfare can be achieved in both extensive and intensive systems, provided that husbandry practices are appropriately adapted to the needs of sheep as a species.
