Poultry welfare
Proper animal welfare involves providing the proper housing, management, nutrition, disease prevention and treatment, responsible care, humane handling and, when necessary, humane euthanasia. These factors allow for the most optimal and humane growing environment. The concept of animal welfare includes three elements: the bird’s normal biological functioning, its emotional state and its ability to express its natural behaviors. Improving animal welfare can be accomplished through offerings like poultry feed enrichment, which can reduce stress, thereby increasing performance, productivity and profitability. Animal welfare is currently a major requirement for intensive poultry production. Beak trimming, stocking density, free access to feed, heat stress, and air pollutants became important issues, which are regulated in several countries. Animal welfare is observed by watching how birds naturally behave and even by looking at mortality stemming from aggressive behaviors.
Air quality control in poultry farms is a fundamental factor to ensure animal welfare, health, and performance. Some environmental parameters are controlled periodically, like humidity and temperature, although there are others, like environmental ammonia concentration, which do not suppose a deep concern for farmers, and whose related economic losses are always underestimated. Ammonia: Origin and effects on poultry Ammonia is a toxic and irritant gas ...

1. Introduction The welfare of laying hens has been the subject of interest in consumers, industry, and the government in Chile. The current main egg production system in Chile is the intensive cage system [1], allowing high egg production (3.9 thousand million in 2019) for an increasing human population. Joint efforts have been carried out between the industry, universities, and the government to establish minimum welfare conditions, including the development of the Good...

Decisions that impact hen welfare may be influenced by the expectations of the community, such as development of regulations (Coleman et al., 2018). Although some reaserch has been conducted on Australian consumer attitudes (Bray and Ankeny, 2017), wider community perceptions (for example, vegans) towards laying hen welfare remain largely unknown.
This research was approved by the University of New England’s Human research ethics committee (HE18-235). Focus groups of industry...

Free range hens are exposed to various potential stressors including weather conditions and risk of predation (Gilani et al., 2014). Distress can result in impaired biological functions including reduced reproduction, immunity and growth (Palme, 2012). In order to investigate the impact of early range usage, corticosterone concentrations in egg albumen were measured in response to a stressor (manual handling and relocation) in free range hens. Two groups (n = 625) of commercial free...

High ambient temperatures coupled with high humidity can be devastating to commercial broilers. Heat stress interferes with the broiler´s comfort and suppresses productive efficiency. Although increased heat is seen as a major problem in poultry production, studies show that it is not only the excessively high temperatures, but also the fluctuation of the temperature which is more detrimental for a broiler to perform. Heat stress is a significant source of economic loss...

Tessa Grebey and colleagues researched dustbathing behavior in a range of commercial laying hen breeds, including Hy-Line Brown, Bovan Brown, DeKalb White, and Hy-Line birds.
They found that strains respond to social situations differently.
DeKalb White and Hy-Line W36 birds dustbathe in larger groups (10-11 birds), compared to the brown breeds (3-4 birds)
DeKalb White and...

1. Introduction In free-range and aviary housing systems, individual hen behavior can vary significantly, such that, some hens rarely access the outdoors while others utilize the range regularly [1–4]. Free-range and aviary housing systems provide hens with horizontal and vertical space, allowing for various choices, opportunities, and interactions; including dust bathing, sunbathing, perching, and exploration which are believed to improve hen welfare [5,6]. However, not...

1. Introduction One of the main goals of free-range egg production is to optimise laying performance and egg quality while supporting hen health and welfare. However, opportunities provided in the free-range system allow for the expression of a variety of behaviours, interactions and physical experiences (e.g., being exposed to uncontrolled environmental conditions) which may impact hen health, welfare, and survival [1–3]. For example, free-range flocks are frequently...

I. INTRODUCTION The global supply of poultry products will need to double by 2050 if we are to meet the aspiration of all people to be food secure. We will need to produce more poultry meat in the face of changing consumer perceptions and constrained resources. Consumers expect this to be achieved in a sustainable manner. The industry has the skills to achieve this. Genotypes continue to improve; production methods and business models are evolving; and we have enhanced our...
