“…The blood corticosterone, glucose and triglycerides were lower than respective levels in controls. Olsson & Keeling (2005) and Dixon et al (2008) found that the behaviour of taking dust baths is an important indicator of social welfare of birds. According to Sherwin & Kelland (1998), the higher welfare in turkeys increased the time spent in stretching, feather pecking, and dust bathing.…”

The welfare assessment model in poultry under different rearing systems has gained increasing importance. An economically profitable approach for improvement of laying hens welfare during the hot summer period is diet's supplementation with specific additives (microelements, vitamins, and minerals) to satisfy the body's needs under heat stress. The purpose of the present study was to evaluate the welfare of DeKalb Brown laying hens (n=295) whose feed was supplemented with either 10 mg/kg Larginine or with the combination 10 mg/kg L-arginine and 250 mg/kg vitamin C during the hot summer days, using a mathematical assessment model. The laying hens' welfare was scored on the basis of birds' behaviour, plasma corticosterone levels, blood biochemical parameters (glucose, cholesterol, creatinine, total protein and triglycerides) and rearing microclimatic parameters. The behaviour was observed by a video camera accounting the number of birds engaged in specific forms of activity: ingestive (ingestion of water or food), gregarious (moving, resting, egg-laying, dust bathing and feather cleaning), sexual and agonistic behaviour. The plasma corticosterone levels were assayed by means of commercial ELISA kit. Blood biochemical indices -cholesterol, glucose, creatinine, total protein and triglycerides were determined on an automated biochemical analyzer. The welfare score of DeKalb Brown laying hens during the hot period from the control group was 33.33% that of the group supplemented with L-arginine -66.67 %, and in birds supplemented with arginine and vitamin C -73.33 % due to the synergic heat stress-reducing effect of both compounds.

“…latency to emerge from a box and response to a tonic immobility test), which was interpreted as a response to the anxiety associated with not performing this maintenance activity. Later, Olsson and Keeling (2005) suggested that the selection operates directly on the fear response because dustbathing is realized only when the bird is not at risk of predation. The pre-laying behaviour of laying hens (sitting activity) is among the rare stereotypes observed in livestock.…”

Behavioural adaptation of farm animals to environmental changes contributes to high levels of production under a wide range of farming conditions, from highly controlled indoor systems to harsh outdoor systems. The genetic variation in livestock behaviour is considerable. Animals and genotypes with a larger behavioural capacity for adaptation may cope more readily with varying farming conditions than those with a lower capacity for adaptation. This capacity should be exploited when the aim is to use a limited number of species extensively across the world. The genetics of behavioural traits is understood to some extent, but it is seldom accounted for in breeding programmes. This review summarizes the estimates of genetic parameters for behavioural traits in cattle, pigs, poultry and fish. On the basis of the major studies performed in the last two decades, we focus the review on traits of common interest in the four species. These concern the behavioural responses to both acute and chronic stressors in the physical environment (feed, temperature, etc.) and those in the social environment (other group members, progeny, humans). The genetic strategies used to improve the behavioural capacity for adaptation of animals differ between species. There is a greater emphasis on responses to acute environmental stress in fish and birds, and on responses to chronic social stress in mammals.

“…It acts to remove skin parasites, regulate the amount of feather lipids, and maintain plumage condition (Olsson and Keeling, 2005). Hens have been found to work to obtain a dustbathing substrate, and after deprivation of dustbathing, are more motivated to dustbathe, indicating that it is a high priority (Widowski and Duncan, 2000).…”

“…However, the dustbathing sequence cannot be completed, as there is no substrate, nor shaking off lipid-saturated dust. Sham dustbathing lacks positive feedback (Widowski and Duncan, 2000), does not satisfy birds' motivation for dustbathing (Olsson and Keeling, 2005), and indicates a reduced state of welfare (Lay et al, 2011). Further, when birds are unable to dustbathe, plumage is in a poorer condition as it is dirtier, less waterproof and less insulative (Scholz et al, 2014).…”

“…However, the evidence on the motivation to access substrate for dustbathing is not as conclusive as the motivation to access other resources, and some some sstudies have not found any evidence of a motivation to dustbathe. It has been suggested that the methodology used, for example, whether or not hens can see the litter in the experiments, may affect differences between studies (Olsson and Keeling, 2005).…”
