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.
Coccidiosis is a disease caused by Eimeria spp. and causes a negative economic impact on the poultry industry, inducing global losses over 2.4 billion dollars annually (1). Specific Eimeria spp. identified in poultry includes E. acervulina, E. brunetti, E. maxima, E. necatrix, E. praecox, E. mitis, E. tenella, E. mivatti, and E. hagani (2). Eimeria spp. colonize in the intestine from duodenum to ceca, leading to inflammation, hemorrhaging, and diarrhea. Damaged intestine caused by...

INTRODUCTION In South Africa and worldwide, the poultry sector contributes immensely to the global food security status of consumers (1). According to the Food and Agriculture Organization (FAO) (2), the demand for poultry feeds is increasing due to the high growth of commercial and smallholder poultry enterprises. Moreover, in the poultry sector, feed accounts for approximately 60–80% of the total cost (3), with fish and soybean meal used as the main protein sources. However,...

I. Introduction Immediately after birth, or hatch in birds, the initial inoculum shapes the gut microbiota for life. The first bacteria to settle in the intestine can attach to epithelial cells with no competition, rapidly establish, grow, and set the intestinal environment to suit their own needs (Stecher and Hardt, 2011; Edwards, 2017). The first bacterial settlers have the most substantial influence on developing the host's immune system and overall ability to thrive (Stecher...

I. INTRODUCTION The following statement was made by Landers et al., (2012) in a public health report. “Although the majority of antibiotic use occurs in agricultural settings, relatively little attention has been paid to how antibiotic use in farm animals contributes to the overall problem of antibiotic resistance”. Some classes of antibiotics are becoming less effective due to overuse and microbial adaptation leading to resistance to treatment. The pool of...

INTRODUCTION Corn is one of the major components of poultry feed, and up to 65% of finished poultry feed can be comprised of corn and corn byproducts (Alqaisi et al., 2017). Poultry diets are often contaminated with more than one mycotoxin. Fumonisins (FB) and deoxynivalenol (DON) are secondary mycotoxin metabolites produced by Fusarium verticillioides and Fusarium graminearum, respectively (Glenn, 2007). According to the 2021 survey by Biomin, FB and DON are the most prevalent...

1. Introduction The use of antibiotics growth promoters (AGPs) has been a common practice in intensive poultry production to improve animal growth performance, health, and sustainability of animal farming (1). However, AGPs threaten human health due to the risk of developing antimicrobial resistance and drug residue in poultry products (2). Consequently, AGPs have been prohibited in several countries, including the European Union, the United States, and China. However, AGPs...

INTRODUCTION Campylobacteriosis is among the most frequently reported bacterial foodborne infection in both the European Union (EU) and the United States, with Campylobacter jejuni as the major causative agent. In the last decade, the number of confirmed infections in the EU exceeded 200,000/year. Symptoms of campylobacteriosis include diarrhea, fever and cramps. Death rarely occurs, but complications can increase more than fivefold due to infections with antibiotic-resistant...

INTRODUCTION Livestock monogastric species, including swine and poultry, are the main sources of meat; therefore, they are, at the same time, the main livestock species reared under intensive conditions (Eurostat, 2022). The pressure to increasingly optimize breeding resulted in antimicrobials often being used for both prophylactic and metaphylactic purposes to counteract the diseases of these animals or as growth promoters. It is currently commonly recognized that the misuse of...

Annelies Kers (Utrecht University) Knowledge of factors that influence the functioning of gut microbes is essential to improve health and reduce the use of antibiotics in poultry production. The environment, and more specifically housing conditions, can affect the gut microbiome of broiler chickens. The gut microbiome is defined as the collection of all the microorganisms and their “theatre of activity” in the gut environment. Previous...
