I. Introduction Methionine plus Cysteine (Cys) requirement of poultry and swine has been determined using graded levels of DL-Met. Currently, Aviagen recommends 0.95, 0.87, and 0.83% SID Met plus Cys for starter, grower, and finisher phases of Ross 308 broilers (Aviagen, 2019). Cobb recommends 0.88, 0.80, and 0.74% SID Met plus Cys for the respective growth phases (Cobb, 2018). Similarly, Brazilian tables recommend 0.99, 0.97, and 0.91% SID Met plus Cys for broilers starter, grower,...

I. Introduction Phytase, apart from increasing phosphorus (P) availability from plant ingredients, improves availability of non-P nutrients like Ca, amino acids (AA), and energy (AME) by facilitating the breakdown of phytate P and thus negating its antinutritional effects (Dersjant-Li et al. 2016). Phytase along with carbohydrase enzymes could improve productivity of chickens with a lower feed cost when proper downspec (reduction of nutrient levels in the diet) is applied. It is...

1. Introduction Listeria monocytogenes is a foodborne pathogen of notable concern, especially due to its growth under household refrigeration temperatures (40 ◦F, 4 ◦C) and at a pH range of 4.5 to 9.6 [1–3]. Listeria monocytogenes has been subdivided into four phylogenetic evolutionary lineages due to variations in ecology recombination rates and genomic content [4,5]. Lineage I consist of most human clinical isolates and includes serotypes 1/2b, 3b, 3c, and 4b...

INTRODUCTION Finding effective strategies to improve chicken’s feed efficiency (FE) is a major goal to decrease overall production costs, preserve additional edible resources for humans, and reduce the ecological footprint of chicken rearing systems (Bottje and Carstens, 2009; Yan et al., 2017). Chickens of divergent FE differ in several phenotypic characteristics with the most obvious difference being the lower feed intake of high feed-efficient chickens compared to low...

Description of problem Feed ingredients and feed manufacturing account for 60 to 70% of production costs in an integrated poultry operation. Modern commercial broilers are fed predominately pelleted diets, and researchers have demonstrated how improving pellet quality (PQ), by increasing the percentage of pellets in the diet, further enhances bird performance (Proudfoot and Sefton, 1978; Dozier et al., 2010; Corzo et al., 2011; Lilly et al., 2011; Glover et al., 2016; Lemons and...

1. Introduction The best strategy to optimize production and reproduction in poultry species while mitigating the harmful effects of environmental conditions is proper nutrition 1,2,3 . One of the pillars of nutrition is the use of amino acids in poultry diets, among which Methionine (Met) represents the first limiting amino acid in broilers. As Bunchasak 4 reported, Met can act as an amino acid in the synthesis of protein and polyamine, a sulfur donor, a...

1. Introduction As feed grade amino acids are commercialized at prices that are economically feasible for including in industry poultry diets, nutritionists are able to better supply diets containing amino acid profiles more closely representing ideal amino acid profiles (Baker, 1997). Refinement of dietary amino acid profiles allows for reductions in crude protein (CP), inclusion levels of protein-rich ingredients in the diet and nitrogen excretion in broiler chickens (Kidd et...

INTRODUCTION Conventional broiler production is dependent on maize as a source of energy and soybean meal as a source of protein. Nutrient digestibility of plant-based feeds in poultry is limited by the proportion of their components for which there are no corresponding endogenous enzyme secretions. These components include non-starch polysaccharides (NSPs) that are present within the cell walls of maize and soybean meal 1,2 . The NSPs are either indigestible or of very...

1. Introduction Coccidiosis is a major enteric infection of poultry that is estimated to cost more than USD 14.5 billion annual losses globally [1]. Although coccidiosis control using various anticoccidial chemicals, such as ionophores, coccidiocides, and coccidiostats, has long been a mainstream strategy in modern poultry production, alternative control strategies to antibiotics are necessary owing to the antibiotic ban [2]. Therefore, much effort has been made to develop...

Enzyme supplements are used widely in poultry diets in an attempt to improve poultry performance, feed consumption, and also minimized environmental pollutions due to the reduced output of excreta 1 . Different enzyme supplements have been developed with respect to their target substrates in feed ingredients. Exogenous xylanase is an example of an enzyme supplement to improve nutritional factors by efficiently decomposing the non-starch polysaccharides (NSP) 2 ,...

Introduction The need for the animal sector to create ever-more-sophisticated strategies for producing animal protein in increasingly environmentally and economically responsible ways is growing. In addition to setting up ethical and environmentally friendly structures for subsequent generations, this is done to ensure that food is safe for consumption today [1, 2]. The incorporation of feed additives to accomplish these objectives has grown increasingly crucial as regulations...

Introduction High cost of conventional ingredients such as maize as source of energy, soybean, groundnut cake and fish meal as source of protein in broiler’s diet has increased the cost of feed and consequently increased cost of production (Attia, 2015). The cost of feed represents about 75% of the total costs of animal production. Also, non-availability and competition existing among man, industry and livestock have necessitated the need to find cheap and available...

1. Introduction The global demand for chicken-meat is increasing. Globally, poultry meat is expected to represent 41% of all the protein from meat sources in 2030 and exceed the 34% share for pig meat, 20% for beef and 5% for sheep meat [1]. In Australia, the 46.9 kg per capita chicken-meat consumption in 2021/22 is clearly superior to pork (27.7 kg), beef (19.1 kg) and lamb (5.5 kg) with a 47.3% market share [2]. To meet this high consumption, Australian broiler operations processed...

About the study Phytase supplementation has become a standard practice for poultry diets to enhance phosphorus (P) utilization and subsequently reduce P excretion. Previous phytase studies on hen performance, eggshell and bone quality have been done over short durations and using hens of varying ages. The knowledge gap is that there are no long-term phytase studies covering the rearing period through the end of production cycle. The objective of this study was to...
