Nutritional composition, nitrogen-corrected true metabolizable energy, and standardized amino acid digestibility of palm kernel meal from several countries [PDF]
Poultry ScienceExtensive nutritional analyses were conducted for palm kernel meal (PKM) sourced from 5 countries. Two precision-fed rooster trials were conducted to evaluate the nitrogen-corrected true metabolizable energy (TMEn) and standardized amino acid (AA ...

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

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

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 ...

True metabolizable energy, standardized amino acid digestibility, and digestibility of phosphorus in soybean expellers produced from conventional or high-oil varieties of soybeans fed to chickens [PDF]
Poultry ScienceThe objective was to test the hypothesis that nitrogen-corrected true metabolizable energy (TMEn), standardized amino acid (AA) digestibility, and apparent ileal P digestibility are not different in soybean expellers produced from high-oil soybeans (SBE ...

Poultry Science, 1987 The sensitivity of several bioassays was determined using soybean meal and two autoclaved soybean meals. Chick growth study results revealed that a four percent difference in weight gain was sufficient to show statistical significance (P less than .05) between the diets.

Determination of TMEn, standardized amino acid digestibility, phosphorus digestibility, and phosphorus bioavailability in conventional and reduced phosphorus distillers dried grains with solubles [PDF]
Poultry Science, 2023 : The TMEn, amino acid (AA) digestibility, and P availability in 2 conventional corn distillers dried grains with solubles (C-DDGS1 and 2; 0.86 to 1.14% P, DM basis) and reduced phosphorus DDGS (RP-DDGS; 0.39% P) were evaluated. The TMEn of C-DDGS1 and 2

PSXIII-27 Evaluation of Protein Quality of Select Chicken-Based Protein Sources Using the Precision-Fed Cecectomized Rooster Assay [PDF]
J Anim Sci, 2023 Abstract The objective of this experiment was to determine and compare the standardized amino acid (AA) digestibility of chicken-based protein sources using the precision-fed cecectomized rooster assay. Four ingredients were tested: spray-dried chicken protein hydrolysate (CPH), spray-dried chicken meat (CC), spray-dried chicken broth ...
