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 Chickens have a well-developed trichromatic vision system composed of diverse photoreceptors and cones [1], allowing them to perceive a broad range of the color spectrum [2]. Chickens can see in ultraviolet wavelengths and perceive colors that are not visible to most mammals [3], including humans [4]. The chickens’ sharp visual capabilities allow them to effectively survey their surroundings and localize feed [5,6]. In addition, broiler chickens have shown...

1. Introduction Factors such as investments in breeding facilities and the adoption of advanced technologies have been decisive in consolidating Brazil’s global leadership in broiler chicken exports [1]. Among the available structural typologies, the “dark house” stands out as an intensive production system, equipped with automated systems that control variables such as temperature, relative humidity, wind speed, and light intensity. The precise control of these...

What is the pre-slaughter phase? The preslaughter phase is the last phase of the broiler chicken’s life before slaughter. This phase includes multiple steps: withdrawal of feed and water, catching, loading into transportation crates, and transportation by road, In some cases, chickens may be placed in lairage (waiting area)...

1. Introduction For decades, the livestock production sector has focused on improving animal production efficiency to stretch out the world population’s needs concerning farmed products [1]. This is particularly true for conventional broiler chickens’ production, where advancements in genetics, nutrition programs, management strategy, and medicine have resulted in more efficient birds, allowing a decrease of the slaughter age dramatically [2,3]. This is well illustrated...

1. Introduction 1.1. Background Chickens struggle to recognize other individuals after visible changes are applied to the comb or plumage [1]. Much like chickens are able to use visual cues to differentiate each other, artificial intelligence (AI) is capable of utilizing image or video inputs for reidentification (re-ID) purposes. Animal re-ID, the task of identifying individual animals within one (or sometimes several) species, finds applications in various fields,...

The Unseen Cost of Price Fluctuation Poultry farmers and integrators live with constant uncertainty. One day, the live bird price is INR 100/kg; the next day, it's INR 70. Despite careful planning and biosecurity, they find themselves at the mercy of a market without controls, hedging tools, or predictability. This snake-and-ladder game isn’t just a minor inconvenience. For thousands of farmers and integrators, it means boom-or-bust cycles, mounting debt, and...

Broiler farming is a dynamic business, but one of its biggest challenges is managing birds during hot and humid conditions. While broilers are bred for rapid growth, their ability to regulate body temperature is limited, making them vulnerable to heat stress. Signs of Heat Stress: 1. Increased panting and open-mouth breathing. 2. Increased water intake and reduced feed intake. 3. Lethargy and reduced activity levels. 4. Restlessness and seeking shade. Causes...

INTRODUCTION The ability to maintain an affordable, safe, and sustainable food supply is a global challenge. Meat consumption trends are changing, with increasing preferences for cheaper and processed white meat and a decline in cereals share of the total food (Sefeedpari et al., 2013; Faridi et al., 2011). The consequent increases in poultry meat production by a factor of seven (3206%) and eggs by a factor of three have overburdened sustainable production (Sousa et al., 2005)....
