I. INTRODUCTION Phytogenics and probiotics are gaining more attention in the animal industries due to market trends to reduce antibiotics use, whilst still preventing disease outbreaks and maintaining, or even improving, animal performance. Phytogenics have been shown to inhibit non-beneficial, potentially pathogenic bacteria such as E. coli (Ouwehand et al., 2010, Bento et al., 2013), positively influencing the gut microbiome and inhibiting C....

I. INTRODUCTION Human consumption of chicken meat products has risen exponentially over the past five decades and continues to grow on a global scale. Thus chicken meat production has seen unparalleled expansion, to meet the continually increasing consumer demand (Allievi et al., 2015). Such expansion has resulted in the chicken meat industry being at the forefront of animal production, where advances in animal nutrition and genetics are near optimal. Therefore, producers...

One of the reasons chicken meat is considered a healthy food is due to its relatively low-fat level. Black soldier fly (BSF) larvae are a promising alternative feed ingredient for monogastrics, including poultry. However, the impact of feeding BSF larvae in broiler diets on the fatty acid profile of the breast chicken meat remains unknown. This study aimed to investigate the impact of up to 20% BSF larvae dietary inclusion on the fatty acid profile of meat chicken breast meat when fed until...

Poultry rely on enzymatic digestion more so than any other livestock species due to their very short digesta transit time and because their large intestines lack the bacteria that aids other species in digestion. Because of this, their ability to digest nutrients in the feed is not absolute. Recently, along with phytase and non-starch polysaccharide-degrading enzymes, protease has become a standard component in broiler diets to improve nutrient digestibility and utilization. However, there...

I. INTRODUCTION While the inclusion of feed enzymes is routine in poultry fed sorghum-based diets, the effects of these enzymes are often muted or substandard, especially with phytase (Selle et al., 2018). The exact mechanism for this underperformance is not known, however, it is most likely caused by one or all of three key endogenous grain components: kafirin, phytate and phenolic compounds. Phenolic compounds,...

I. INTRODUCTION The inclusion of exogenous phytases in diets for broiler chickens has developed into a routine practice because of their positive phosphoric and extra-phosphoric effects. On one hand, phytase liberates phytate-bound phosphorus (PP) which is found in all plant-sourced feedstuffs as the dominant P fraction. On the other, phytase enhances amino acid (AA) digestibilities, essentially because they...

I. INTRODUCTION The AgriFutures Australia Chicken Meat Program funds research, development and extension activities for the benefit of the Australian chicken meat industry. Through the process of reviewing the 5-year strategic plan (RIRDC, 2014), the objectives were adjusted to align each objective with a stage of chicken meat production. This included the consolidation of all research related to the live chicken...

Feed represents the primary cost of broiler production, thus the formulation of cost-effective diets that meet broiler nutritional requirements is critical. To ensure this objective is met, nutrient specifications of feed ingredients must be accurately determined. However, Australian broiler nutritionists have expressed concern, as many nutrient specification databases contain dated information or lack Australian specific data. Therefore, the aim of this project was to compile current...

I. INTRODUCTION Estimating the available energy of feed ingredients is fundamental to formulating a well-balanced diet and lower the production cost. Measurement of apparent metabolisable energy (AME) is the accepted standard procedure for evaluating the available energy value of ingredients for poultry, as it is simple and straightforward and considers most of the energy losses after digestion and metabolism (Carré et...

I. INTRODUCTION Cereal grains are ground prior to feed mixing to reduce the particle size with the aim of modifying their physical characteristics. This facilitates handling, mixing and further processing (extrusion and pelleting) and increases the exposure of nutrients in the endosperm to digestive enzymes (Amerah et al., 2011). Available recommendations regarding optimum particle size are contradictory, due to...

Copper (Cu) is a vital element involved in various physiological and biochemical processes, namely cellular metabolism and enzyme systems. Higher levels of copper than nutritional requirements (up to 250 mg/kg) are supplemented to poultry diets. However, if in excess, excreted Cu can contaminate the environment. High levels of copper sulphate (CuSO 4 ) may damage other dietary nutrients through increased oxidation. Meanwhile, copper hydroxychloride (IBC) is less soluble than...

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...

INTRODUCTION Hemp ( Cannabis sativa L.) is an annual herbaceous plant belonging to the family Cannabinaceae 1 , traditionally grown for fiber and seed production. Whole hemp seed contains approximately 25% crude protein, 33-35% oil and 34% carbohydrate, in addition to a broad range of vitamins and minerals 2-4 . Hemp seed oil contains 75 to 80% polyunsaturated fatty acids (PUFA), including 60% linoleic acid and 17-19% α-linolenic acid...

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...

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...
