I. INTRODUCTION Sustainability comprises three principal components: the environment (demand for resources and potential for environmental pollution), ethical issues (welfare of man and his animals), and economic robustness (FAO, 2012). At first glance, insect protein is a sustainable alternative to traditional protein sources such as soybean meal. Insect production requires less land, water and other resources than traditional protein sources, and they can be raised on...

1. Introduction The performance and activities of male breeders (roosters) are critical for egg fertility and hatchability in commercial layer and broiler breeding houses [1,2]. In a study, researchers found positive correlations between rooster body weight and both the laying intensity of fertilized eggs and the hatchability percentage of chicks [2]. A review by Kingor [1] underscores the importance of how the physical conditions and management of roosters can directly impact...

Introduction Poultry scientists have long discussed and debated how the energy values of feed ingredients should be expressed (Zuidhof 2019). Pesti (2024) suggested that it is time for a paradigm shift in the way feed ingredient nutrient contents are described, and labeled the new categories collectively the Armidale method (see Fig. 1 for examples). He also proposed expanding the net energy (NE) to NEATP, based on the production of adenosine triphosphate (ATP) system of...

1. Introduction Poultry is the most consumed animal protein source in the world, and the trend is expected to continue increasing [1]. The world population reached 8 billion in 2022, and is likely to reach 9 billion in 2037 [2], which will continue to increase pressure on the global chicken-meat industry. One way to meet this increasing demand is to improve the efficiency of chicken-meat production. Precision nutrition is a strategy to improve growth efficiency, reducing the...

INTRODUCTION Reducing the production cost of quality meat and eggs for the ever-growing world population is a prime target of the poultry industry. Conventional feed ingredients like corn and soybean meal are widely used in broiler feeding programs, which increase the competition among food and feed and lead to raise production costs (Donohue and Cunningham, 2009; Stefanello et al., 2016). Several strategies were attempted to minimize the cost per unit production, such as...

Introduction With genetic improvement changes, today poultry species are more sensitive to nutritional and management changes which can easily induce osmoregulatory perturbation that can cause flushing (Many, 2023). A typical layer farm of 100,000 hens produces 1,500 to 2,000 tons of manure every year (Chai, 2012). And 1000 broilers chickens produce up to 1370 lbs of manure per in a growing cycle (Parker et al., 1959). Manure is acquired by the agricultural industry for land...

INTRODUCTION The world’s population is growing exponentially, causing a rise in demand for animal-based protein. To meet the meat demand, broiler chickens have been genetically selected for higher feed efficiency and high muscle yield. As a result, these broiler chickens produce a high amount of metabolic body heat and are highly susceptible to heat stress (HS), especially during the summer. Moreover, chickens lack sweat glands and have feather covers, which make them extremely...

INTRODUCTION There is an increasing demand for animal-based protein to meet the nutritional needs of the ever-increasing global population. The protein obtained from broiler meat is one of the most promising animal-sourced proteins, considering its quality and affordability. To contribute to the supply of animal-based protein, fastgrowing broiler strains have been developed for higher muscle yield in a short period. However, broiler’s faster growth in a limited time results in...

Nutritional factors of gut inflammation (D. Korver) The intestinal tract is one of the largest, if not the largest, surface areas exposed to the environment of humans and poultry (Ferrer et al., 2003; Helander and Fandriks, 2014). Although the digestive tract is contained within the body, the lumen is actually outside of the bird. Therefore, although the function of the intestinal tract is usually thought of as being the uptake of nutrients, it has another important function:...

Leg health is an integral part of the economics of poultry. It is estimated that approximately 12.5 billion poultry worldwide suffer from various leg injuries each year (Nicol, 2013; Xu et al.,2025). According to a review of Huang et al (2023), leg diseases in the United States have caused economic losses of more than 80 million to 120 million US dollars in the broiler industry (Huang et al. 2023). These could indirectly lead to a further decline in reprocessing margins and reduce the gross...

Introduction Salmonella, a gram-negative, rod-shaped, facultatively anaerobic bacterium in the Enterobacteriaceae family, is a zoonotic pathogen responsible for human gastrointestinal disease. Contaminated poultry products, particularly meat and eggs, are the primary source of Salmonella infection in humans (1). Nontyphoidal S. enterica serovars, such as Typhimurium and Enteritidis, can infect multiple host species, complicating their transmission dynamics. Although these serotypes...

Introduction The poultry industry plays a vital role in global food security, providing an affordable and efficient source of animal protein (Castro et al., 2023). However, maintaining flock health and productivity remains a major challenge, with intestinal health playing a central role in poultry performance (Korver, 2023). With the rise of antibiotic resistance across the globe, the potential restriction of in-feed antibiotic growth promoters (AGPs) in animal food production could...

1. Introduction Newcastle disease (ND), caused by an avian paramyxovirus ser otype 1 (now designated as orthoavulavirus 1) [1], and infectious bronchitis (IB) caused by an avian coronavirus [2], are known to give rise to severe diseases in chickens, with disastrous economic losses and welfare concerns [3,4]. ND and IB have been important and common chicken diseases worldwide since 1926 and 1936 respectively. In the last three decades, publications from both our and other...

Numerous liver diseases originate from prior alterations in the intestinal barrier and the gut microbiota. The gut-liver axis has an anatomical and immunological connection that makes the liver the first organ exposed to everything that crosses the intestinal barrier. The intestinal mucosa constitutes the body's most important biological barrier. In addition to absorbing nutrients, it acts as a defense structure capable of preventing the passage of microorganisms, endotoxins,...

INTRODUCTION To maximize the profitability of the broiler breeder production chain, it is necessary to increase egg production and hatching rates to obtain more viable offspring. The inclusion of substances with antioxidant properties in the diet of broiler breeders aids the enzymatic defense system in controlling the damage caused by free radicals in cells. Carotenoids are an example of this type of substance because they have antioxidant, pigmenting, provitaminic and...
