“…A large proportion of comfort behavioural patterns and minor appearance of agonistic behaviours can especially testify to a high level of welfare of hens kept in a given production system. Stretching of the wings, wing flapping, dustbathing, sunbathing and preening are often referred to as comfort behaviours [ 24 , 25 ]. Agonistic behaviour is any social behaviour-related fighting.…”

This study investigated the welfare of laying hens in different non-caged housing systems, namely a deep-litter barn system (BS), a free-range system (FRS) and an organic system (OS). The study was conducted on 270 hens of a native breed Green-legged Partridge (Z-11) and 270 Hy-Line Brown hybrids. Visual scans were performed to record behaviour of hens. Hens were housed in groups of 30 and observed over the course of one day at 20, 36 and 56 weeks of age. Dustbathing, scratching, wing stretching, wing flapping and preening were recorded as comfort behaviours. Pecking, fighting, threatening and chasing were recorded as agonistic behaviours. The percentage of run use was higher in native hens than in commercial hens (p < 0.05). The proportion of hens exhibiting comfort behaviours housed in the FRS and OS was similar but over twice as high as in the BS (p < 0.05). In the FRS and OS, the percentage of hens displaying comfort behaviours increased with age (p < 0.05). In all the production systems, the percentage of birds displaying comfort behaviours was higher in native breed hens than in commercial breeds (p < 0.05). In the BS, the higher proportion of hens displaying an agonistic behaviour was seen more in commercial breed than in the native breed hens (p < 0.05). The percentage of birds displaying an agonistic behaviour declined with hen age, both in commercial and native breed hens.

“…Therefore, it is not a surprise that today's legislation requires animals to be housed in a "naturalized" environment, as is the case of laying hens, for example, a cage should be equipped with things for climbing, hiding, poking about and plucking. (Costa et al, 2012). …”

Abstract:Behavior is the fastest way of animal adaptation to changes that occur in its organism or in its habitat. This is a visible feature of animals. Therefore, veterinarians can use knowledge about animal behavior in many branches of veterinary practice and veterinary science. Knowledge of animal behavior can also be helpful in diagnostics in veterinary practice. In addition, knowledge of animal behavior can be applied in all animal treatment procedures, as well as in their restraint, animal examination, animal learning and training, animal tracking, feeding, reproduction and many other activities. Accommodation systems and all kinds of enrichment of living conditions are part of applied animal behavior science. Veterinarians must know how to prevent behavioral disorders and pathological forms of animal behavior, but also how to treat them. They also need to know how to apply knowledge about animal behavior to protect animal welfare. Applied animal behavior science can be applied to control game animals and pests in a more humane way as well as in conservation of species. There are many other examples of application of animal behavioral knowledge in veterinary practice, as it is presented in this paper.

“…High AW degree is achieved in the absence of negative situations and affective states and in the presence of positive situations and affective states (Boissy et al, 2007). Some behaviors may promote AW, with physical, psychological, and social benefits, whereas negative behaviors may compromise the welfare of birds submitted to frustration or anxiety (Costa et al, 2012). There are few evidences of the emotional states poultry, but behaviors such as running, jumping, feeding, singing, resting, and dust-bathing are considered pleasant activities, while hunger, thirst, discomfort, pain, and feat are considered unpleasant (Appleby et al, 2004).…”

Scientific information on the welfare of broilers reared in alternative systems is scarce. The objective of this study was to assess the welfare of free-range broilers using the Welfare Quality® protocol. Free-range broilers reared in ten farms were observed, and measures were made in broilers of five of these farms. The collected data were transformed into scores (0-100), with higher scores indicating better welfare, except for emotional states. Prevalence percentages were calculated for the remaining data. Median (min-max) scores were 81 (63-98) for lameness, 93 (83-99) for hock burn on the farm, 100 (95-100) for plumage cleanliness, 35 (8-70) for podermatitis on the farm, 56 (26-88) for density, 53 (20-53) for dust, 34 (14-67) for litter quality, 93 (41-100) for drinkers, and 100 (100-100) for birds panting or huddling on the farm. The following average (min-max) prevalence percentages were obtained: total mortality 2.0% (1.4-7.2%), culling 0.0% (0.0-2.2%), feed withdrawal time 875 min (715-945 min), water withdrawal time 220 min (170-275 min), dead on arrival at the processing plant 0.00% (0.00-0.01%), broken wings 0%, (0-0%), inefficient stunning 3.9% (1.3-6.7%), pre-stun shock 49.3% (26.7-56.8%), hepatitis 4.5% (1.8-11.0%), bruising 9.3% (6.7-16.7%), and ascites 0% (0-0%). The negative broiler welfare points detected were pododermatitis, litter quality, density, dust, culling, feed withdrawal time, inefficient stunning, pre-stun shock, and hepatitis. The positive points identified were the absence of birds panting or huddling on the farm; low prevalence of lameness, hock lesions, dead on arrival, broken wings, and ascites; good plumage cleanliness scores, and short water withdrawal time.
