I. Introduction Salmonella spp. in poultry pose a serious risk for food safety. The complex nature of Salmonella infections in poultry requires a multifactorial solution. It is key to preventing Salmonella colonization throughout the entire gastrointestinal tract (GIT). Short chain fatty acids (SCFA) have been described as having beneficial effects in the upper part of the gut, whereas medium chain fatty acids (MCFA) target the lower GIT (Van Immerseel et al., 2009). Coated butyrate...

I. Introduction Poultry diets are currently formulated based on total calcium (Ca) and available phosphorus, with a ratio of 2:1 being maintained between them. For a number of reasons, there is increasing interest in shifting the formulations based on digestible Ca and digestible P. To enable this move, information is required of the requirements of digestible Ca and digestible P. A recent study at our laboratory (David et al., 2021) determined the standardised ileal digestible (SID)...

I. Introduction Wheat and sorghum are the two major feed grains used in Australia for broiler diets; however, wheat is more common and is usually considered better quality than sorghum. The local chicken meat industry may have to increase by 60% to meet demand in 2050 so strategies are needed to promote sustainable chicken-meat production to meet this anticipated demand. Crude protein reductions in broiler diets could be a major factor in the quest for sustainable production....

As in commercial broiler chicken production, broiler breeder performance depends upon adequate dietary trace minerals, including zinc (Zn), manganese (Mn), and copper (Cu). Broiler breeder diets currently used in the industry contain levels of the inorganic forms of these minerals with generous safety margins. Researchers now report that combining inorganic sources of Zn, Mn, and Cu with organic hydroxy analog of methionine (HMTBa) forms in breeder hen...

We know that young geese benefit from warmer drinking water, but what is the optimal water temperature? Poultry scientists take a closer look
A new investigation into goose health suggests providing drinking water that is at least 18? (64.4?) may boost the activity of digestive enzymes, promote intestinal development, increase water consumption, and even increase goose eye temperature. Based on their findings, the...

Particulate matter (PM) can damage bird lungs. Now poultry scientists gather data to give a fuller picture of the effects of PM in different housing systems
Poultry scientists are working to better understand the impacts of particulate matter (PM) on bird health and production. Particulate matter includes very small particles of feed, feathers, animal waste, and dander. Researchers have found that PM...

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...
