INTRODUCTION Natural medicinal products originating from herbs and spices have been used as feed additives for poultry (Guo et al., 2004). Compared with synthetic antibiotics or inorganic chemicals, these plant-derived products have proven to be natural, less toxic, residue-free, and are thought to be ideal feed additives in feeds for animal production (Wang et al., 1998). Any attempt to improve poultry production and increase its efficiency, therefore, needs to focus on the...

Introduction It is widely appreciated that a variety of new technologies and human behavioral change will be required to feed an estimated population of 10 billion people by 2050 with environmentally sustainable production. It is also estimated that about one third (in weight) of the world’s food is lost or wasted annually. In 2021 the poultry industry supplied some 286 eggs per capita to consumers in the US market alone [1]. Remarkably, this has been achieved with an...

Introduction Heat stress (HS) is one of the most challenging environmental stressors despite the modern climate control equipment in broiler chickens’ houses. Broiler flocks may be seasonally exposed to HS that varies in intensity according to the relative humidity of the region [1]. Multiple studies have identified the various adverse effects of acute or chronic HS on chickens, such as a severe reduction in feed intake and growth [2–4], systemic alkalosis [5],...

Introduction Locomotory activity is strongly associated with broiler chicken welfare; many behavioral patterns that depend on locomotion, such as exploration, seeking food, water, shelter, and escaping predators, are negatively affected by the poor walking ability in fast-growing broiler chickens [1]. Rapid muscle growth and exacerbated development of the Pectoralis major muscle in fast-growing broiler chickens change the chickens’ center of gravity, altering the...

Introduction The emergence of antimicrobial resistance (AMR) in enteric bacteria of humans and animals is a global health threat that has decreased treatment efficacy and increased the cost of infections with antimicrobial-resistant bacteria [1, 2]. It is projected that by 2050 an estimated 10 million AMR-related infections will occur worldwide [3]. Surveillance systems play a critical role in the mitigation and containment of AMR by monitoring antimicrobial use (AMU) and...

Introduction Inert digestibility index markers are the anchor of many feeding trials designed to analyse nutrient utilisation and amino acid digestibility along the gastrointestinal tract of animals. Marker use is widely accepted as a method less laborious than total tract retention. Additionally, it enables the determination of digestibility along intestinal sections in ruminant and non-ruminant animals [1]. Digestibility markers, chromium dioxide, CrO 2 , or chromic...

Introduction Food safety is a central concern in the poultry industry, with pathogens such as Salmonella causing outbreaks associated with meat and eggs [1]. Nearly 1 in 25 packages of chicken products at the average grocery store are contaminated with Salmonella, and Salmonella causes 1.35 million cases of infection every year in the United States (US) [1]. A multi-state Salmonella Enteritidis outbreak in 2021 connected to not ready-to-eat (RTE) products has refocused producer...

Light and dark cycles within a 24-hour period play a crucial role in maintaining physiological and behavioral rhythms in animals. In birds, daily rhythms associated with feed intake, physical activity, sleep-wake cycles, and physiological rhythms are influenced by photoperiod. The ancestors of domestic chickens, the Red...

The hatching phase of broiler production refers to the last three days of incubation, which are embryonic days 18-21. This phase of embryonic development is critical for the chick’s survival, as well as welfare and production later in life. In commercial hatcheries, eggs with viable embryos are transferred from incubators to...

The holiday season is once again here, which means many kitchens will be filling up with baked goods and savory dishes. It is also the time of year when the use of eggs increases for all of those delicious dishes! However, eggs can be a potential source of Salmonella bacteria that can cause illness or in rare cases even death. Here are some tips to...

Introduction The main issues that burden the broiler industry today might be caused by genetic selection strategies, such as a rapid growth rate, a decreasing slaughter age and facilitating feed efficiency [1]. Indeed, achieving extreme growth potential is a serious biotic stress factor that is accompanied by health problems leading to systemic diseases [2,3]. The path mechanisms of most common infectious diseases, including pneumonia, sepsis and enteritis, are directly linked...
