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.
1. Introduction Eggs offer accessible and affordable sources of high-quality protein along with important micronutrients [1]. With the growing population, demand for table eggs continues to rise [2]. Meanwhile, consumers are demanding improved animal welfare, with a notable shift in table egg production from caged to cage-free (CF) systems [2,3]. Considering the welfare issues in conventional cages (CC), CF housing systems are gaining momentum globally [4,5]. As part of this trend,...

Winter brings a unique set of challenges to modern poultry production, especially in open or poorly insulated houses. As temperatures drop, chickens expend more energy just to maintain body heat, which diverts nutrients away from growth, egg production, and immune function. Prolonged cold stress elevates...

The brooding area of most broiler houses requires a heating system capable of providing between 40 and 60 Btu's/hr to maintain an air temperature in the low 90's during cold weather. For instance, a 54' X 250' brooding area would typically require a heating system capable of producing between 675,000 BTU/hr (54' X 250' X 40 BTU/hr = 540,000 BTU/hr) and 810,000 BTU/hr (54' X 250' X 60 BTU/hr = 810,000 BTU/hr) depending on climate and house...

A house tightness test is conducted on a 40' X 500' broiler house using a 54" tunnel fan that moves 25,900 cfm @ 0.10". With everything closed, the 54" fan generates a static pressure of 0.20", which would be considered a relatively tight house by most. Using the Poultry411 Poultry House Leakage Area Calculator, it was determined that the house had a total of approximately 12 ft 2 of cracks in the end and side walls, tunnel doors, and fan shutters. The producer...

Introduction Slow-growing broilers have recently gained traction in mainstream broiler production in some European countries due to their improved leg health and welfare compared to conventional broilers (Rayner et al., 2020; Abeyesinghe et al., 2021; Baxter et al., 2021). Slow-growing broilers have been shown to have a better gait, lower prevalence of hock burn and footpad dermatitis (Rayner et al., 2020; Baxter et al., 2021), and perform more behaviors associated with positive...

Description of the problem Broiler chicks are typically exposed to continuous or near-continuous light for their first week of life (Scanes and Christensen, 2019), a practice supported by many broiler management guidelines (Aviagen, 2018; Cobb, 2021). The rationale behind this approach is to provide chicks with ample time for feeding during their rapid growth phase. However, the effectiveness of continuous lighting for modern fast-growing broilers during brooding remains...

Introduction Dorsal cranial myopathy (DCM) is characterized by muscular changes, including degenerative and multiphasic lesions that specifically affect the anterior Latissimus dorsi (ALD) muscle in chickens, a superficial, bilateral muscle located in the dorsal region of the wings, which functions as an abductor of the humerus and wings [1–4]. Macroscopically, the ALD muscle region affected by DCM shows yellow, odorless, gelatinous edema under the skin [5,6]. The muscle...

Mycotoxins are known to decrease health and performance in poultry production. Their modes of action, such as reducing protein synthesis and promoting oxidative stress and apoptosis, lead to cell destruction and lower cell replacement, affecting several organs and tissues. When different stress factors collude, such as high temperatures and humidity, poor ventilation, high stocking density, and management events, the effects of in-feed mycotoxins can reach a higher level, which may...

1. Introduction
Stress, a response to adverse stimuli, is difficult to define and understand because of its nebulous perception. According to Selye [1], “stress is the nonspecific response of the body to any demand”, whereas stressor can be defined as “an agent that produces stress at any time”. Therefore, stress represents the reaction of the animal organism (i.e., a...

I. INTRODUCTION Alternative rearing systems are becoming increasingly important mainly because of growing public concerns about intensive systems. Regulations have been established in some countries to restrict or ban the use of conventional systems. The European Union banned the use of conventional battery cage systems in 2012 and alternatively, new enriched colony cages, free range production systems or barn systems have been introduced as substitutes (Leinonen et al., 2014). As a...
