Introduction Poultry producers attempt to control infectious diseases through a variety of means, including appropriate farm management practices and breeding genetically resistant lines (Sartika et al. 2011; Scott et al. 2018). Unfortunately, existing farming conditions favour increased chicken densities in poultry houses, increasing the risk of spreading entero-pathogens such as Salmonella and Clostridium spp. (FAO 2013). For over half a century,...

Introduction Clostridium septicum (CS) is a ubiquitous, spore-forming bacterium associated with spontaneous gas gangrene in both livestock and humans. The spores can persist in harsh environments, such as the gastrointestinal tract or tissue, and remain undetected for extended periods. When environmental conditions are appropriate for growth, the spores will germinate and proceed to proliferate. CS is capable of producing a variety of toxins. However, the alpha-toxin is the one...

1. Introduction Food safety and economic gains are the priority consideration for food animal production industry. The antibiotic growth promoters (AGP) have been used in animal feed for decades to promote animal health and production. However, extensive use of antibiotics in animal agriculture led to increased concerns over antibiotic contamination in food and environment, and the emergence of antibiotic-resistant microorganisms. With the reduction and eventual withdrawal of...

1. Introduction Deoxynivalenol (DON) is a secondary metabolite produced by Fusarium fungi. DON is the most widespread mycotoxin found in grains such as wheat, rye, barley, maize, oats, and their byproducts [1,2]. A recent survey, reported that DON is the most frequent contaminant of feedstuffs in Europe [3]. From 4311 samples evaluated, 63% were positive, with an average positive level of 0.6 mg/kg and a maximum of 40.7 mg/kg. For poultry feeding stuffs, the recommended maximum...

Paulo Martins, thank you for your comment, an intensive Salmonella monitoring that includes at the minimum the detection and serotyping is certainly important to understand what type of Salmonella is persisting in poultry environments. We should be more proactive in that sense and not just wait for a regulation to exist to start acting. Governments should promote this as well and reward those companies who make the effort to detect, identify and characterize the pathogen to look for better...

Introduction Exosomes are membrane vesicles, approximately 40–100 nm in diameter, and present in most biological fuids [1–3]. Exosomes are derived from multivesicular bodies (MVBs) to form intraluminal vesicles (ILVs), which are then released into the extracellular environment as exosomes after fusion with the plasma membrane [3]. Lipids and proteins are the main components of exosomes and various nucleic acids, such as mRNAs, microRNAs (miRNAs), and other...

Poultry feed contains major ingredient i.e., soybean meal as the principal source of protein. Soybean meal is the dominant protein supplement used in poultry diets & also has an excellent amino acid profile the primary protein source in poultry diets. In recent years most producers are looking for alternate protein sources of soybean due to skyrocketing of the commodity. There are some alternative protein sources which have been used by poultry/feed producers as a...

Barley ranks fourth in global cereal production after corn, wheat and rice. About 65% of the world’s barley produced is fed to animals, including poultry. Australia is a significant global producer of barley, ranking in the top 5 countries with about 5% of global production and is among the top 3 barley exporters accounting for about 30% of malt and 20% of feed barley trade. Australia is a reliable supplier of two-row spring barley that is suitable for a wide range of malting, brewing...

Calculating a proper stocking density will determine the maximum farm profitability in broiler chickens. Choosing the stocking density implies knowing the impacts on live performance, and its interrelations with the environment and dietary nutrients. Abundant studies about stocking density run under non-commercial conditions might not indicate the best reliable information to know the farm profitability. As a result, few studies are reliable for commercial purposes. Poultry managers should...

INTRODUCTION The genetic improvement of modern broiler lines has contributed to the success of the poultry industry worldwide. Since the 1950s, slaughter age has been reduced by approximately 40%, and slaughter weight has more than doubled. Current lines have been genetically improved with focus on rapid growth and maximum performance based on continuous improvement of feed conversion. Embryonic development (ED) accounts nowadays for more than 33% of the whole life period of...

1. Introduction Contamination of cereal grains and their byproducts by mycotoxins is a worldwide problem negatively affecting poultry production [1]. Two Fusarium mycotoxins which are among the most toxic and frequent feed contaminants are the trichothecene deoxynivalenol (DON) and fumonisins (FUM). DON is produced as a secondary metabolite by Fusarium graminearum and Fusarium culmorum, whereas FUM are secondary metabolites which are mainly produced by Fusarium verticillioides...
