1. IntroductionThe use of antibiotics growth promoters (AGPs) has been a common practice in intensive poultry production to improve animal growth performance, health, and sustainability of animal farming (1). However, AGPs threaten human health due to the risk of developing antimicrobial resistance and drug residue in poultry products (2). Consequently, AGPs have been prohibited in several countri ...

1. IntroductionThe application of antibiotics on poultry farms has been linked to the global emergence of multi-drug-resistant (MDR) bacteria in recent years (Benrabia et al., 2020; Kaonga et al., 2021). MDR bacteria can spread from food-producing animals to humans through direct contact with the food chain and the environment (Kirbis and Krizman, 2015). One-Health issues are still an im ...

IntroductionModern broiler chickens are most certainly a most visible manifestation of genetic advancements. At hatch, a Cobb500 broiler weighs 42 grams. This newborn chick grows 31 % (55 g/bird) in just twenty-four hours. By day 35 of age, this chicken reaches a body weightof 2,521 grams, representing 5,902 % relative to hatching mass (Cobb-Vantres 500, 2022). Genetic selection, food, health, and ...

IntroductionMicroorganisms constitute the largest fraction of biodiversity on Earth. Their functions are highly diverse, with fundamental roles to maintain chemical equilibria and cycles in their respective environments. It is, therefore, surprising that many humans consider all microorganisms as ”dangerous”, particularly when it comes to equating bacteria with pathogens (Musso et al., ...

1. IntroductionThe permeability of the intestinal tract controls the uptake of nutrients and the transport of unwanted extracellular substances such as bacteria and xenobiotics, in addition to the non-digested substances. Therefore, gut health plays an essential role in the pathogenesis of various intestinal disorders. The permeability of the intestine is controlled by gut microbiota, digestive se ...

In the past few years, the concept of “gut health” has established itself as a norm in the scientific literature and animal production. Although the term “gut health” is not specially well-defined, scientists are in agreement that it refers to the capacity of the gastrointestinal tract (GIT) to carry out normal physiological processes and to maintain homeostasis, thereby en ...
