Laying hens’ preferences for nest surface type are affected by enclosure

The nest surfaces preferred by hens are inconsistent with those typically provided in commercial settings. However, little research has explored hens' preferences for commercially available nest surfaces. Our objective was to compare hens' preferences for two such surfaces – red...

Feeding from perches in an aviary system reduces aggression and mortality in laying hens

Some commercial aviary systems for laying hens allow birds to access feed by standing on perches instead of platforms. Despite reports that providing laying hens with perches relates to reduced aggression and cannibalism, and increased prevalence of keel bone damage,...

Perch-shape preference and perching behaviors of young laying hens

Provision of perches in enriched colony or cage-free hen housing facilitates birds' ability to express natural behaviors, thus enhancing animal welfare. Although considerable research has been conducted on poultry perches, further investigation is needed of perching behavior and preference of...

Effects of horizontal distance between perches on perching behaviors of Lohmann Hens

Perching is a highly-motivated natural behavior of laying hens that has been considered as one of the essential welfare requirements. The objective of the study was to evaluate perching behaviors of laying hens as affected by horizontal distance (HD) between...

Abnormal repetitive behaviours in captive birds: A Tinbergian review

Abnormal repetitive behaviours (ARBs) are associated with past, or present, welfare problems and are common elements of the behavioural repertoire of some captive animals, including birds. Millions of birds from hundreds of species are held in various captive settings, yet...

Effect of litter material and stocking density on bone and tendon strength, and productive performance in broilers

Litter material and stocking density were evaluated on welfare-related variables and productive performance in broilers. Male chicks (n = 744, “Ross 308” strain) were raised on either tezontle (TEZ) or wood shavings (WS) litter, with a stocking density of either...

Providing laying hens in group-housed enriched cages with access to barley silage reduces aggressive and feather-pecking behaviour

Two trials were conducted to study the effect of feeding barley silage on the behaviour and performance of beak-trimmed laying hens. In each trial, 20 hens and 2 roosters were housed in each of eight group-housed enriched cages, with four...

Evaluation of alternative euthanasia methods of neonatal chickens

Hatched male layer chicks are currently euthanized by maceration in the United States. Public concerns on the use of maceration have led to the search for alternative methods. We hypothesized that gas inhalation and low atmospheric pressure stunning (LAPS) are...

Assessment of plumage and integument condition in dual-purpose breeds and conventional layers

The assessment of plumage and integument condition in laying hens provides useful information about the occurrence of feather pecking and cannibalism. Although feather loss and skin injuries can result from mechanical abrasion or clinical diseases, they are valid animal-based indicators...

Free dietary choice and free-range rearing improve the product quality, gait score, and microbial richness of chickens

Poultry welfare has been extensively studied; however, there is a lack of rigorous scientific knowledge relating to the different aspects of welfare factors and how this may contribute to the production quantity and product quality as well as the welfare...
