Increasing dietary phytate has a significant anti-nutrient effect on apparent ileal amino acid digestibility and digestible amino acid intake requiring increasing doses of phytase as evidenced by prediction equations in broilers [PDF]
Poultry Science, 2020 : Cobb 400, male broilers (n = 4,752) were housed in 12 pens/diet and 33 birds/pen. There were 3 levels of phytate P (0.24, 0.345, or 0.45%) and 4 phytase doses (0, 500, 1,000 or 2,000 phytase units (FTU)/kg) to evaluate the influence of phytate and ...

Growth performance of male broiler chickens in different growth phases in response to amino acid concentrations in the pre-starter diet [PDF]
Journal of Animal Science and TechnologyAn experiment involving 720 one-day-old male broilers (Ross 308) was conducted to investigate the effects of graded levels of crude protein and standardized ileal digestible (SID) amino acids (AA) on growth performance during the pre-starter period (0 to

Additivity of digestible energy and nutrient concentrations in hatchery byproducts fed to nursery pigs [PDF]
Animal Bioscience, 2022 Objective The objective was to test additivity of digestible energy and nutrient concentrations in the hatchery byproduct mixture fed to nursery pigs. Methods In the previous studies, energy, phosphorus, calcium, and amino acid digestibility of infertile

True ileal amino acid digestibility and digestible indispensable amino acid scores (DIAASs) of plant-based protein foods [PDF]
Food Chemistry, 2021 Plant-based protein foods are increasingly common, but data on their nutritional protein quality are scarce. This study evaluated it for seitan (wheat-based food), tofu (soya-based food), soya milk, and a pea emulsion. The true ileal digestibility (TID) of their amino acids was determined in minipigs, to calculate the digestible indispensable amino ...

Variation among arthropod taxa in the amino acid content of exoskeleton and digestible tissue
Ecology and Evolution, 2023 Arthropod consumption provides amino acids to invertebrates and vertebrates alike, but not all amino acids in arthropods may be digestible as some are bound in the exoskeleton.

Digestible indispensable amino acid score and digestible amino acids in eight cereal grains [PDF]
British Journal of Nutrition, 2014 To determine values for the digestible indispensable amino acid score (DIAAS), it is recommended that ileal amino acid (AA) digestibility values obtained in growing pigs are used to characterise protein quality in different foods. Therefore, an experiment was conducted to determine the standardised ileal digestibility (SID) of AA in eight cereal grains

Available versus digestible dietary amino acids [PDF]
British Journal of Nutrition, 2012 Available amino acids are those absorbed from the gastrointestinal tract in a form suitable for body protein synthesis. True ileal digestible amino acids are determined based on the difference between dietary amino acid intake and unabsorbed dietary amino acids at the terminal ileum.

Biomarkers and De Novo Protein Design Can Improve Precise Amino Acid Nutrition in Broilers
Animals, 2022 Precision nutrition in broilers requires tools capable of identifying amino acid imbalances individually or in groups, as well as knowledge on how more digestible proteins can be designed for innovative feeding programs adjusted to animals’ dynamic ...
