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...
NOREL participated in the Poultry Research Days (JRA) in France, represented by its Area Sales Manager for France, Germany, and Belgium, Marie Cadieu. This French scientific congress was held over two days, on March 18 and 19, 2026, in the city of Tours. The event is organized every two years...
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,...

Victor Naranjo, Technical Director at Evonik Animal Nutrition, explains from a technical perspective what guanidinoacetic acid (GAA) is and how it supports animal energy metabolism. He also discusses its reliability during feed processing and handling, and outlines the key nutritional factors that must be considered to maximize the benefits of GAA in animal production systems. ...
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...

Background North Carolina’s poultry farmers produced 36 million turkeys and 800 million broiler chickens in 2012 (NASS, 2013). Most turkeys and broilers are raised on bedding such as wood shavings, peanut hulls, or sawdust. Fecal material, spilled feed and water, and feathers accumulate on the bedding, creating a material known as cake. The material beneath the cake, which is mostly bedding with some fecal and feed constituents, is known as litter. In North Carolina, most...
The Poultry Research Foundation, in conjunction with WPSA - Australian Branch, cordially invites you to attend the 38th Annual Australian Poultry Science Symposium, to be held at The University of Sydney Business School Belinda Hutchinson Building (H70) (Camperdown Campus), Monday 1st - Wednesday 3rd, February,...
1 | Introduction Broiler production fundamentally depends on the quality of fertile eggs and chick output, with incubation representing a critical process in this context. For production efficiency, day‐old chicks must exhibit high physical, sanitary, and immunological qualities (Araújo et al. 2019). Chick quality at hatch is strongly associated with broiler performance throughout the production cycle, directly influencing the productivity of the poultry industry...
Introduction It is assumed that net energy (NE) represents the most accurate way to value a feed for productive purposes (Barzegar et al., 2020; Liu et al., 2017; Wu et al., 2019). This explains the variations in the metabolic utilization of metabolizable energy (ME) from nutrients and ingredients (Noblet, 2015), explains the loss of energy as heat (Swick et al., 2013), and allows for more accurate prediction of the productive response of animals. The composition of diets (type...
There has been an observed increase in the presence of agricultural chemicals in drinking water (1). However, the health risks associated with chronic exposure remain poorly understood (2). Most risk assessments rely on single-chemical studies, despite evidence that mixtures exert synergistic or compensatory effects on host physiology and microbial function. Xenobiotics, including pesticides and emerging contaminants such as microplastics (MPs), enter livestock and humans primarily...

1. Introduction Intense genetic selection, combined with an effective feeding program and efficient rearing management greatly improved productivity and efficiency of broiler production [1]. Despite the low genetic variation and well-controlled rearing environment in modern broiler production, there can still be noticeable variations in body weight (BW) within a flock [2]. Ideally, broiler production wants to produce homogenous products for production efficiency [3]. High variations...
