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.

Jeyashree Elango (University of Delaware) speaks on the ability of enteroids to act as an alternative model of the chicken gut, providing a rapid way to screen antibiotic alternatives and their compatibility through the host responses against them, during the 11th Symposium on Gut Health in Production of Food Animals in St. Louis, USA....
INTRODUCTION Campylobacter is a prevalent foodborne pathogen in poultry such as chicken and turkey. It causes foodborne disease in humans (campylobacteriosis) due to consumption of contaminated poultry products, thus constituting a major public health issue (Sahin et al., 2002; Newell and Fearnley, 2003). Control of Campylobacter in poultry to improve microbiological safety is a primary concern for consumers and government food safety agencies (Lin, 2009). Traditionally,...
INTRODUCTION Avian coccidiosis is one of the most common enteric diseases of poultry, and it is caused by several protozoan parasites of the genus Eimeria (1). The disease is characterized by reduced weight gain and feed conversion efficiency and is the most economically significant parasitic infection of the global poultry industry (2). Eimeria tenella is one of the seven most prevalent Eimeria species in chickens; it is the causative agent of cecal coccidiosis, causing severe...
INTRODUCTION In the modern poultry production system, the first reported chick embryos injection of thiourea was done by Grossowicz in 1946 to observe the effect in hatchling and post-hatch life (1), followed by thyroxin by Balaban and Hill (2). Later, in ovo technique (IOT) was first opted for vaccination against Marek’s disease by Sharma and Burmester (3). Subsequently, the success of in ovo vaccination (IOV) has set forth a paradigm shift in the poultry industry by adapting...
INTRODUCTION Providing adequate quantities of animal protein to meet the demands of a continuously growing population requires that livestock producers must increase the production efficiency of farm animals. This can be achieved through improved genetics, management, and nutrition. Furthermore, feed ingredient prices continue to increase, resulting in minimizing the profit for the producers and forcing them to seek cheaper alternative ingredients, typically of lower quality and...
Poultry industry experts at the 2024 Latin American Poultry Summit will present information on topics that address avian influenza concerns. The program is organized into four sessions, and the first two sessions will be “Epidemiology of Avian Influenza” and “Vaccination.” Each session will feature two speakers followed by a panel discussion. The Summit is presented by the International Poultry Expo (IPE), part of the International Production & Processing Expo...
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 Every animal production system experiences stress because of the numerous stressors on the farms. Stress is a biologically adaptive response to re-establish homeostasis (1). Heat stress is a variant of environmental stress caused by an increase in environmental temperature (and humidity) beyond the thermotolerance of an animal. Poultry birds possess a narrow range of thermoregulatory thresholds and are sensitive to environmental temperatures, which can pose as a...
1. Introduction Salmonella enterica has emerged across the globe as a threat to health systems [1]. Serovars of this species can infect humans, causing diverse effects varying from typhoid fever to gastroenteritis [2]. Non-typhoidal Salmonella (NTS) is associated with millions of infections and thousands of deaths annually around the globe [3,4]. S. Typhimurium and S. Enteritidis are considered the principal serovars associated with human infections; nevertheless, S. enterica subsp....
Intestinal welfare is one of the most important and more complex objectives to achieve and maintain in animal production. In commercial production, the gut is under high pressure because of the metabolic effort and challenging agents present, which may favor intestinal imbalances and the reduction of nutrient utilization, decreasing production efficiency. Therefore, a good status of intestinal health is key for a sustainable and profitable poultry production , and the reinforcement of...
INTRODUCTION Demand for poultry source foods is increasing, particularly in developing countries (1), and this is driven primarily by population growth (2, 3). To keep pace with the growing request for poultry products, farmers now use antibiotics at minute doses to reduce the incidence of enteric pathogens, improve feed conversion ratio (FCR) and body weight gain (BWG) in broiler chickens (4). Despite the significant economic benefit of AGPs in large-scale broiler production, their...
In recent years protein feed ingredients are consistently increasing in cost and protein in poultry diets has become one of the most expensive nutrient. Urbanization is putting pressure to produce more and high quality protein sources in less space. Neutralizing substandard quality feed ingredients with effective tools has also become a new concern. In parallel people are more concerned on impact of animal agriculture on environmental pollution. Hence research has focused in the direction to...
I. Introduction Feed is the largest cost in poultry production, particularly in recent times due to the increased price of protein and energy sources. Feed cost can be reduced with the inclusion of alternate protein and energy sources like pearl millet, deoiled rice bran (DORB), meat and bone meal (MBM), dried distillers’ grains with solubles (DDGS) and mustard deoiled cake (MDOC) replacing soya bean meal (SBM) and corn. However, these alternate ingredients have low...
I. Introduction Plant-derived isoquinoline alkaloids (IQ) have the potential to support gut integrity and growth performance under conditions of enhanced stress such as heat stress. The previous study revealed that the BW increased in the IQ group, and the level of FITC-d, to evaluate the gut barrier function, reduced in the IQ supplement group (Kitasato et al., 2021). However, a comprehensive study on the effect of IQ on growth performance and gut integrity under heat stress during...
The increasing prices of major feed ingredients have prompted animal nutritionists to use inexpensive raw materials in their diet formulations to lower feed cost. However, due to their relatively lower digestibility, diets formulated with these raw materials often lead to poor gut health status and animal performance. For instance, poor protein digestibility results in the formation of toxic metabolites that can impair gut health and subsequently confer negative effects on broiler...
