Broiler chickens grow rapidly with nutrient requirements changing daily. However, broilers are fed 3-5 diet stages throughout their growth, meaning nutrients are under- and over-supplied throughout production (Kleyn, 2013). Thus, blending rations on a daily basis to meet the daily energy and lysine requirements may improve the efficiency and reduce the coefficient of variation (CV) in broiler floc ...

INTRODUCTIONChicken meat consumption has drastically increased in the past decades, and Australia has the fourth highest consumption of chicken meat in the world, eating 47.64 kg/person in 2020 (ACMF, 2021). The success of the poultry industry is highly related to the improved growth and performance capabilities of chicken meat birds with some strains of broilers capable of reaching market weight ...

I. INTRODUCTIONThe current system of feeding laying hens with a fully mixed diet, that attempts to meet all the nutrient requirements of the birds, only really developed with the introduction of cage housing facilities after the Second World War. Research on confining laying hens to cages ramped up in the first half of the 20th Century in California but it was not until the late 1940s that the fir ...

BackgroundMaintaining and improving gut health is fundamentally important as the gut supports optimal digestion and therefore performance and profitability of production. Managing gut health through barrier function is regarded as a new frontier for disease prevention across different species [1]. In poultry, considerable research has been done on improving animal performance and gut health throug ...

INTRODUCTIONPoultry production is one of the largest sources of animal protein supply for human consumption in the world. For many countries, like Australia, chicken-meat is the dominant animal protein, therefore production must continue to expand to supply increasing demand. In Australia, for instance, per capita consumption of chicken-meat is predicted to increase by 7.9% over the next 5 years [ ...

I. INTRODUCTIONHuman 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 advan ...

I. INTRODUCTION Exogenous phytase improved ileal amino acid digestibility by an average of 5% based on 745 observations across 24 studies in a systematic review (Cowieson et al., 2017). Nevertheless, the post-enteral availability of amino acids is ultimately determined by their transition across enterocytes in the gut mucosa. Amino acids may be denied access to the portal circulation because they ...
