Amino acid and energy digestibility of conventional corn dried distillers grains with solubles, high protein distillers dried grains, and corn fermented protein, and impacts on turkey poult growth performance and intestinal characteristics [PDF]

Poultry Science
: Amino acids (AA) are an expensive nutritional components of poultry diets. Distillers dried grains with solubles (DDGS) is the primary co-product produced by the dry grind bioethanol industry, although new technologies are being implemented to produce ...

Amino acid digestibility and protein quality of mealworm-based ingredients using the precision-fed cecectomized rooster assay. [PDF]

J Anim Sci, 2023
AbstractMealworms may serve as an alternative protein source for pet foods because of their high protein content and low environmental footprint. The amino acid (AA) content and protein quality of mealworm-based ingredients may vary depending on their composition and processing, however, so testing is required.

Amino acid digestibility and protein quality of fermented soybean-based ingredients using the precision-fed cecectomized rooster assay. [PDF]

J Anim Sci
Abstract Soybean meals, soy protein isolates, and other forms of soy have served as protein sources in pet foods for many years. The amino acid (AA) content and protein quality of soybean-based ingredients vary depending on their composition and processing, however, so the testing of new ingredients is required.

Effect of low‐temperature drying on the nitrogenous compounds and inositol phosphates in broiler chickens and cecectomized laying hen excreta

Animal Science Journal, Volume 92, Issue 1, January/December 2021., 2021
Abstract We investigated how the chemical composition of broiler chicken and cecectomized laying hen excreta is affected by drying in a forced‐air drying chamber at low temperatures. Excreta that was immediately frozen after voiding provided the reference values. The excreta were dried in drying chambers for 4 hr, 6 hr, and 12 hr at 23°C or 33°C in the

Comparing the standardized amino acid digestibility of an alternative protein source with commercially available protein-based ingredients using the precision-fed cecectomized rooster assay. [PDF]

J Anim Sci, 2023
Abstract Using single-cell-based proteins in pet foods is of interest, but little testing has been done. Therefore, our objective was to determine the amino acid (AA) digestibilities, assess protein quality of a novel microbial protein (MP) (FeedKind), and compare it with other protein-based ingredients using the precision-fed ...

Nutrient and AA digestibility of black soldier fly larvae differing in age using the precision-fed cecectomized rooster assay1 [PDF]

Journal of Animal Science, 2019
Abstract Edible insects such as black soldier fly larvae (BSFL) are alternative protein sources for animal feeds due to their high-protein content and potential low environmental footprint. However, protein quality and AA content may vary across insect species and age.

186 Amino Acid Digestibility of Various Protein-Based Ingredients Using the Precision-Fed Cecectomized Rooster Assay [PDF]

J Anim Sci, 2023
Abstract Given their high protein quality and sustainable production practices, there is growing interest in using single cell-based proteins in pet foods. Because there has been a lack of testing on these proteins, the objective of this experiment was to determine the amino acid (AA) digestibilities of a single cell protein and other ...

Amino acid digestibility and nitrogen-corrected true metabolizable energy of mildly cooked human-grade vegan dog foods using the precision-fed cecectomized and conventional rooster assays. [PDF]

Transl Anim Sci, 2023
Abstract The pet food market is constantly changing and adapting to meet the needs and desires of pets and their owners. One trend that has been growing in popularity lately is the feeding of fresh, human-grade foods. Human-grade pet foods contain ingredients that have all been stored, handled, processed, and transported in a manner that

Metabolizable Energy Values Determined with Intact and Cecectomized Roosters

Poultry Science, 2008
Mature White Leghorn roosters that were intact or cecectomized were used to determine the ME of a diet. Seven intact and 7 cecectomized roosters were fasted for 3 d, with total excreta collection on d 2 and 3. Approximately 1 wk after completion of the trial, the same roosters were force-fed 28 g of a diet that was 85% corn and 15% soybean meal after a
