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...

1. Introduction Campylobacter jejuni has been considered one of the leading causes of human gastrointestinal diseases worldwide, with outbreaks registered both in industrialized and developing countries [1]. Campylobacter spp. colonizes the avian gut in high concentrations with few or no clinical symptoms. Hence, it has been traditionally considered commensal, although a revision of this bacteria–host interaction has been recently proposed [2]. Upon interaction with avian...

1. Introduction In animal husbandry, antibiotics are principally used to prevent, control, and treat diseases. However, they have also been extensively used as growth promoters [1,2]; this practice has been banned in Europe and the U.S. [3,4] but is still widespread in other regions, especially in rural areas, where farmers tend to depend more on antibiotics. Various countries lack legislative measurements to control antibiotic use. Moreover, farmers are not appropriately...

1 Introduction Amino acids are organic compounds containing both amino (—NH 2 ) and carboxyl (—COOH) groups. Due to the presence of asymmetric carbon, all amino acids except glycine exhibit optical activity and exist as D- and L-isoforms or enantiomers (Lehninger et al., 2005). The asymmetric α-carbon imparts chirality, a phenomenon where the molecule is not superimposable to its mirror images in space. Due to this, amino acids except glycine exist in...

Introduction Routine supplementation of dietary Cu, as well as other trace minerals, is intended to prevent deficiencies that originate from the lack of sufficient amounts of this micromineral in the feeds. Copper sulfate (CuSO4) is traditionally utilized as the source Cu of supplementation in poultry feeds because of its wide availability and low cost (1). Total supplemental Cu in commercially formulated broiler feeds is variable, as can be observed in the...

In 2023 mycotoxins semiannual survey, Life Rainbow Biotech randomly collected 152 feed samples of raw materials and feed mills in farms and analyzed. The samples were tested for aflatoxins (B1, B2, G1, and G2), zearalenone, fumonisins (B1, B2, and B3), and deoxynivalenol (DON) by the ELISA Mycotoxin analysis kit. Contamination in animal feed 152 feed samples collected, and 77% were contaminated with fumonisins ( table 1 ). The maximum concentrations of aflatoxins,...

As the global poultry industry has grown and developed, a great variety of consumer products has emerged, focused on convenience and practicality, that provide opportunities to regain value from carcass parts that may have otherwise gone to waste.
During poultry processing, novel products such as fresh sausages can be an alternative use for compromised meats, such as those affected by deep pectoral myopathy (DPM), a recurrent problem in the pectoral (breast) muscles of birds...

Dietary alfalfa may improve broiler growth, but fiber inclusion may be detrimental during coccidiosis challenge.
Alfalfa is a source of health-promoting bioactive compounds (phytochemicals) that may offer several benefits to the poultry industry by direct action or by influencing the microbial communities in chickens.
Iowa State University researchers recently examined the role late-cutting alfalfa — either as ground hay or a lipid-soluble extract — may have on...

Commercial egg laying operations can benefit from more effective and economical ways to depopulate flocks at the end-of-lay while improving worker performance and maintaining or improving animal welfare. Recent on-farm research in Switzerland applied portable blue light units and specialized crate carts, seeking to improve depopulation during catching, carrying, and crating without changes to flock housing or other infrastructure. However, neither the blue light nor the cart reduced layer...
