The Amino Acid Excretion Values in Intact and Cecectomized Negative Control Roosters Used for Determining Metabolic Plus Endogenous Urinary Losses

Poultry Science, 1981
Intact and cecectomized adult male, Single Comb White Leghorns were fasted for 24 hr prior to the initiation of the collection period. Excreta were quantitatively collected from each of the unfed control roosters for a 24 to 48 hr fasting period. The amino acids excretion values (mg/bird/24 hr) were not significantly different (P greater than .05 ...

Chemical Composition, Amino Acid Digestibility, and True Metabolizable Energy of Cowpeas as Affected by Roasting and Extrusion Processing Treatments Using the Cecectomized Rooster Assay

Journal of Applied Poultry Research, 2016
SUMMARY Nutritional differences due to variety, source, and effects of heat processing on cowpeas (Vigna unguiculata) were assessed. The precision-fed cecectomized rooster assay was used to determine amino acid digestibility and TME of cowpeas. Mozambican cowpea (nhemba) treatments included either raw or roasted, whereas those (black-eyed beans ...

Evaluation of four raw meat diets using domestic cats, captive exotic felids, and cecectomized roosters

Journal of Animal Science, 2013
Our objective was to evaluate raw meat diets for captive exotic and domestic carnivores containing traditional and alternative raw meat sources, specifically, beef trimmings, bison trimmings, elk muscle meat, and horse trimmings. We aimed to examine diet composition and protein quality; apparent total tract energy and macronutrient digestibility in ...

Short Communication: Intestinal Digestibility of Amino Acids in Fluid- and Particle-Associated Rumen Bacteria Determined Using a Precision-Fed Cecectomized Rooster Bioassay [PDF]

Journal of Dairy Science, 2014
Microbial protein represents the majority of metabolizable protein absorbed by ruminant animals. Enhanced understanding of the AA digestibility of rumen microbes will improve estimates of metabolizable protein. The objective of this experiment was to determine the digestibility of AA in fluid- (FAB) and particle-associated bacteria (PAB) using the ...

PSIII-24 True Nutrient and Amino Acid Digestibility of Commercial Pork-Based Extruded Dog Foods Using the Precision-Fed Cecectomized Rooster Assay

Journal of Animal Science, 2019
Abstract Pork-based dog foods are increasing in popularity, but there has been a lack of research conducted on these diets, including information about their digestibility. Therefore, the objective of this experiment was to determine the true nutrient and amino acid (AA) digestibilities of commercial pork-based extruded dog foods using ...

PSXI-8 Evaluation of Nutrient Composition and Protein Quality Using the Precision fed Cecectomized Rooster Assay of Novel Avian Protein Sources for pet Nutrition

Journal of Animal Science, 2022
Abstract Alternative protein sources are being incorporated in companion animal diets as a response to the market demand for high quality products. Chicken is a commonly used protein in pet food and was used as a comparison for emerging alternatives goose, quail, duck, and emu which have been evaluated in the current study.

Altering the Bed Depth in the Desolventizer/Toaster (DT) Used in Soybean Meal Preparation Affects Protein Quality and Amino Acid Digestibility by Cecectomized Roosters

Animal Feed Science and Technology, 2007
Abstract To determine optimal processing conditions for preparation of a SBM that will result in optimal amino acid digestibilities, six lots of high protein SBM were produced under different toasting conditions. Specifically, the bed depth in the desolventizer-toaster (DT) was varied (11.4, 12.7, 14.0, 15.2, 17.8, and 20.3 cm).

Effects of Species Raw Material Source, Ash Content, and Processing Temperature on Amino Acid Digestibility of Animal By-Product Meals by Cecectomized Roosters and Ileally Cannulated Dogs.

Journal of Animal Science, 1998
We conducted experiments to determine amino acid (AA) digestibility of nine animal by-product meals using precision-fed cecectomized roosters and ileally cannulated dogs. The products initially evaluated in roosters were meat and bone meals (MBM) containing 24 or 34% ash, poultry by-product meals (PBP) containing 7 or 16% ash, lamb meals (LM ...

PSXI-9 Chemical Composition and Calculation of Standardized Amino Acid Digestibility and Diaas-Like Scores Using the Precision fed Cecectomized Rooster Assay for Novel Proteins of Aquatic and Reptile Species

Journal of Animal Science, 2022
Abstract There has been a quest for novel and alternative protein sources in pet nutrition due to product diversification, need for novel and single protein diets, and concerns with sustainability. However, limited information on chemical composition and amino acid (AA) digestibility of these ingredients are available.
