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...
Spring has come to stay for a few months, everything is getting greener, and the environment is recovering from the harsh cold, but as optimistic as we are, we find spring to be a great moment for raising awareness of poultry’s most common diseases. Want to know some of them? 1. Coccidiosis Represented in poultry...

In the realm of food safety, mycotoxins present a significant challenge to manufacturers, processors, and regulatory bodies alike. These toxic compounds, produced by certain fungi under specific environmental conditions, can contaminate various food and feed products, posing serious health risks to consumers and...
Frank Ivey (Feed2Gain) shares his experience and insights on diet changes, cost savings in formulations, as well as how the impact of enzymes is evaluated, in this Engormix interview....
Ottawa, ONTARIO — What impact will global changes have on Canada’s feed industry? How can local solutions help the sector thrive? How can the feed industry address animal nutrition and feed security to build the sector of tomorrow?
Answers to these questions will be at the...
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...
Introduction The United States (US) has three main broiler chicken production systems which mandate that birds have outdoor access. The first is certified organic production overseen by the United States Department of Agriculture (USDA), which requires that birds have access to the outdoors, with shade, shelter, exercise areas, fresh air, direct sunlight, and protection from predators year-round [1]. The second is free-range poultry production, overseen by the USDA, where...
Introduction Non-typhoidal Salmonella (NTS), one of the principal causes of limiting diarrheal diseases in humans due to the presence of a myriad of virulence determinants, is responsible for approximately 155,000 deaths annually (Pan et al., 2009; Majowicz et al., 2010; Eguale et al., 2015; Balasubramanian et al., 2019; Nale et al., 2021). It is estimated that 93.8 million cases of gastroenteritis caused by Salmonella infection occur worldwide each year...
Introduction It is well known that humans need food in order to survive. When all people, at all times, lack physical and financial access to sufficient, secure, and nourishing food that meets their dietary needs and food preferences for an active and healthy life, food insecurity results [1]. According to [2], around 795 million people globally suffer from chronic undernourishment, and Africa is responsible for more than 60% of the world’s food insecurity. With a hunger...
Introduction Nepal’s poultry industry has seen a significant and rapid growth in the last decade, contributing more than 4% to the national gross domestic product (GDP) [1, 2]. Majority of the poultry products are supplied by numerous commercial farms (54% of total poultry production) scattered throughout the country. Backyard poultry also accounts for significant proportion of the total poultry production (46%); poultry meat and eggs are an easy source for protein and...
Introduction Influenza A viruses (FLUAV) from waterfowl are of global concern. Multiple pandemics have occurred as the product of genetic exchange between FLUAV circulating in humans and the avian reservoir (1). FLUAV contains eight gene segments, two of which encode for the surface glycoproteins hemagglutinin and neuraminidase (HA and NA, respectively). The other six for the internal gene cassette, comprised by the set of polymerases, PB2, PB1 and PA, the nucleoprotein NP, the...
1. Introduction “Feed-food competition” was defined as “the tensions and trade-offs between two alternative uses for edible crops: direct consumption by humans versus feeding livestock” (1). However, feed-food competition includes the use of production resources, such as land, wild fish, and water, and labor, capital, and ecosystem services. The allocation of these resources between all their possible uses is often determined by which end use is most...
