Amino acid digestibility of various feedstuffs using different methods
… for poultry is actually a requirement for amino acids. Recently, there has been much interest in formulating diets on a digestible amino acid basis. The most accepted methods of determining amino acid digestibility are the precision-fed cecectomized rooster assay (PFR) and standardized …

Impact of exogenous factors on amino acid digestibility in non-ruminants
The nutritional value of an amino acid (AA) is determined by its bioavailability, however concept of digestibility is mostly used in practical situations. Four studies were conducted to test 2 exogenous factors that were hypothesized to affect the AA digestibility in non-ruminant animals. In study …

Estimation of amino acid digestibility and its usefulness in swine feed formulation
"The practical utility of digestible amino acid values in swine feed formulation has been a subject of debate among nonruminant nutritionists. Unfortunately, little has been done experimentally to compare values obtained for similar feedstuffs by different methodologies or to validate the …

Amino acid digestibility and concentration of energy in processed soybean and rapeseed products fed to pigs
… were conducted to determine the AA and energy digestibility in 2 sources of enzyme-treated soybean meal (ESBM-1 and ESBM-2), in extruded soybean meal (SBM-EX), in soy protein concentrate (SPC), in conventional dehulled soybean meal (SBM-CV), in conventional 00-rapeseed expellers (RSE), and in a …

Evaluation of several methods for detecting differences in amino acid digestibility among meat and bone meals
Digestibility or bioavailability of amino acids (AA) can vary greatly among meat and bone meals (MBM). Five methods were evaluated to determine AA digestibility or bioavailability among MBM samples; these were the pepsin nitrogen digestibility, the precision-fed cecectomized rooster AA …

Corn Co-Products as Feed Ingredients for Swine: Effects on Growth, Carcass Composition and Fiber and Amino Acid Digestibility
… amounts of CGF and CGM were evaluated. The amino acid and fiber digestibilities of corn co-products were quantified using pigs fitted with ileal cannulas. The use of the cecectomized rooster as a model to predict pig digestibility values was evaluated. The feeding of diets containing 50% CGM …

Effects of the Maillard reactions on chemical composition and amino acid digestibility of feed ingredients and on pig growth performance
… damage on the nutritional composition and AA digestibility of feedstuffs fed to pigs, and also to determine the negative effects of feeding heat-damaged soybean meal (SBM) or heat-damaged distillers dried grains with solubles (DDGS) on growth performance of weanling pigs. In experiments 1, 2, …

Effects of dietary enzyme supplementation on performance, bone ash, small intestinal morphology, and apparent ileal amino acid digestibility of broilers exposed to a live coccidia oocyst vaccine
… tended to improve (P = 0.10) ileal amino acid digestibility (IAAD) in vaccinated broilers in EXP 1 and EXP 3. Phytase supplementation improved (P ≤ 0.05) IAAD and vaccination reduced (P ≤ 0.05) IAAD in EXP 3. Small intestinal morphology and goblet cell numbers were affected by enzyme …

Effect of particle size on nutritional value of soybean meal for poultry
… zero nitrogen retention (TMEn) and standardized amino acid digestibility in seven SBM samples that had a mean particle size of < 386, 466, 809, 1,174, 1,577, 2,026, or 2,321 μm. The TMEn of the SBMs were determined using conventional roosters while the standardized amino acid digestibility was …

Comparative Amino Acid Digestibilities in Growing Pigs and Sows
… gestating and lactating sows are able to digest amino acids. A procedure for surgically inserting a T-cannula in the distal ileum of gestating sows was developed, and ileal fluid was successfully collected from sows in gestation as well as in lactation. It was shown that apparent ileal amino acid …

Effects of inulin or yeast cell wall extract on nutrient digestibility and fecal fermentative end-product concentrations of healthy adult dogs fed raw diets
… their effects on stool characteristics, nutrient digestibility, fecal fermentative end-product concentrations, and fecal microbial populations is needed. The objective of this research was to determine the effects of inulin or yeast cell wall extract (YCW) on macronutrient digestibility, blood …
