Poultry gut health
The efficient conversion of feed into its basic components for optimal nutrient absorption is vital for both broiler and broiler breeder production and welfare. Gut health, an intricate and complex area combining nutrition, microbiology, immunology and physiology, has a key role to play. When gut health is compromised, digestion and nutrient absorption are affected which, in turn, can have a detrimental effect on feed conversion leading to economic loss and a greater susceptibility to disease. In addition, recent changes in legislation on the use of antimicrobials, differing feed requirements and more efficient birds highlight the need for a better understanding of gut function and gut health.
Introduction Between 15 and 20 weeks of age, layer pullets undergo rapid physiological changes, including reproductive tract maturation, ovarian follicles development, increased calcium intake for medullary bone formation, and metabolic and hormonal adjustments to support daily egg production (Xin et al., 2022; Bahry et al., 2023; Noetzold and Zuidhof, 2025). These developmental events impose higher nutritional and immunometabolic demands. Consequently, pullets entering lay are...

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...

INTRODUCTION
For many years, broiler intestinal health was supported by the widespread use of antimicrobial growth promoters (AGPs). These AGPs are antibiotic substances that were added to the feed at subtherapeutic levels, leading to improved animal performance. In the European Union, the use of AGPs was banned in 2006 while the Center for Veterinary Medicine of the US Food and Drug.

The global poultry industry is undergoing a major transformation driven by increasing demand for sustainable production practices, reduced antibiotic usage, and improved feed efficiency. Modern poultry producers are under constant pressure to maintain bird performance while minimizing environmental impact and production costs. In this evolving landscape, sustainable feed additives have emerged as an effective solution for improving poultry gut health, nutrient utilization, and overall...

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...

Introduction Whereas modern broilers have low genetic variation and wellcontrolled rearing environment, there are still high variations in BW within a flock (Lundberg et al., 2021). While uniformity is a universal issue in poultry production, there are still no cost-effective interventions other than culling heavy and small birds to improve uniformity within a broiler flock (Choi et al., 2026). Poor uniformity can cause tremendous economic loss mainly by decreasing efficiency...

Disruptions within the microbiome–gut–bone axis are increasingly recognized as key contributors to impaired bone metabolism and leg disorders in broiler chickens. This study investigated the effects of a combined dietary additive containing Bacillus subtilis DSM 29784 and a phytogenic blend of garlic and essential oil components (BsP) on the modulation of microbial communities, intestinal integrity, mineral utilization, and bone-associated immune–osteogenic...

Abstract The effect of addition of sunflower hulls (SFH) as an insoluble fiber on performance and some physiological parameters of broiler chickens fed diets containing full-fat canola seed (CS) was evaluated from 11 to 42 d of age in a 2 × 2 factorial arrangement of treatments. A total of 240 one-day-old broilers (Ross 308) were randomly devoted to 4 treatments, with 6 replicates each and 10 birds per replicate. Treatments were canola oil source (CS, and...

Butyrate is a short-chain fatty acid that can be given as a dietary additive to support intestinal health and poultry performance. Providing butyrate in a protected form that reaches the hindgut could have different effects than an earlier-absorbed butyric acid salt. To compare these additives, 468 broiler chicks were housed 12 birds per pen, with 13 pens per dietary treatment. Birds were fed a three-phase feeding regimen for 42 d divided into three dietary treatments: a negative...

1. Introduction Corn plays an important role in broiler diets due to its high energy contribution, which makes it an essential ingredient for optimal development and productive performance of broilers [1]. On average, corn provides around 3378 kcal/kg ME [2], which represents around 65% of the energy content of a typical broiler diet [3]. Most of the energy value of corn comes from its high amount of digestible starch. Additionally, corn is rich in essential amino acids such as...

Introduction: Using low-dose antibiotics as feed additives can enhance poultry and swine performance. However, such practices have led to bacterial resistance and antibiotic residues in animal-derived foods. Consequently, there has been a shift towards finding replacements for antibiotics as growth promoters (AGPs). Among the various alternatives, organic acids have emerged as a significant option. Acidifiers have gained attention as viable alternatives to antibiotics in poultry...
