Evaluation of nutritional values of defatted black soldier fly (Hermetia illucens) larvae meal using the precision-fed cecectomized rooster assay. [PDF]

J Anim Sci
Abstract The use of insects, such as black soldier fly (Hermetia illucens) larvae meal (BSFLM), as an alternative protein source for pet food has gained attention due to their high nutritional value. The objective of this study was to determine the chemical composition, amino acid (AA) digestibility, and protein quality of defatted BSFLM

The Effects of Several Oligosaccharides on True Amino Acid Digestibility and True Metabolizable Energy in Cecectomized and Conventional Roosters

Poultry Science, 2007
Prebiotics, such as indigestible oligosaccharides, are considered to be possible dietary alternatives to antibiotic growth promoters in poultry. The effects of indigestible oligosaccharides on nutrient digestibility in poultry are largely unknown. Therefore, an experiment was conducted to evaluate the effects of several oligosaccharides on amino acid ...

Metabolizable energy and amino acid digestibility in spray-dried animal plasma using broiler chick and precision-fed rooster assays [PDF]

Poultry Science, 2022
: Four experiments were conducted to determine ME and amino acid (AA) digestibility of spray-dried animal plasma (SDAP) and soybean meal (SBM). The 48-h precision-fed adult rooster assay was used in 2 experiments; TMEn and standardized AA digestibility ...

Research Note: Influence of Microorganisms on the Lysine and Diaminopimelic Acid Values in the Excreta of Intact, Cecectomized, and Cannulated Roosters

Poultry Science, 1988
Abstract Microbial determinations were made on excreta obtained from intact, cecectomized, and ileal-cannulated roosters. Mean diaminopimelic acid (DAP) quantities in the excreta from intact and cecectomized birds did not differ significantly. The DAP value was greater in excreta from intact and cecectomized birds when they were fed 30 g of either ...

True metabolizable energy, standardized amino acid digestibility, phosphorus digestibility, and phosphorus bioavailability of fermented soybean meal and fermented full-fat soybeans fed to chickens [PDF]

Poultry Science
The objective was to evaluate the nutritional value of conventional soybean meal (SBM-CV), fermented SBM-CV (FSBM), full-fat soybeans (FFSB), and fermented FFSB (FFFSB). In Experiments 1 and 2, two precision-fed rooster assays were conducted to determine

Determination of phytic acid disappearance, ileal P digestibility at different dietary Ca levels, and relative P bioavailability in soybean meal, canola meal, distillers dried grains with solubles, corn fermented protein, and wheat middlings [PDF]

Poultry Science
: Three experiments were conducted to evaluate P utilization in soybean meal (SBM), canola meal (CM), distillers dried grains with solubles (DDGS), corn fermented protein (CFP), and wheat middlings (WM) using different assays.

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

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

Standardized amino acid digestibility in cecectomized roosters and lysine bioavailability in chicks fed distillers dried grains with solubles

Poultry Science, 2009
This study was conducted to compare the concentration of standardized digestible (SDD) Lys and relative bioavailable Lys in 7 sources of corn distillers dried grains with solubles (DDGS). A second objective was to evaluate 2 in vitro methods, reactive Lys and color score, to predict the concentration of SDD Lys and bioavailable Lys in DDGS.

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 ...
