Determination of True Ileal Amino Acid Digestibility in the Growing Pig for Calculation of Digestible Indispensable Amino Acid Score (DIAAS) [PDF]

The Journal of Nutrition, 2020
Digestible indispensable amino acid score (DIAAS) has been recommended by the FAO for the evaluation of protein quality in human foods, but the application of DIAAS is currently limited because of a lack of published data on the true ileal amino acid (AA) digestibility of AAs in foods. The importance of DIAAS is highlighted.

Tryptic digestion of immobilized D‐amino acid oxidase

FEBS Letters, 1978
Received 20 December 1977 1. Introduction The activity of an enzyme is dependent on its conformation and on the structure of its active site. Chemical modification and specific labelling of an active site are useful techniques for the analysis on its structure; however, they often result in undesirable changes in enzyme conformation.

A Salute to PVT TIM HiLL: Indispensable Amino Acids and Global Human Health

Meat and Muscle Biology, 2021
Students are taught the study mnemonic “PVT TIM HiLL” to memorize the 9 indispensable amino acids (IAA): phenylalanine, valine, threonine, tryptophan, isoleucine, methionine, histidine, leucine, and lysine.

Methionine plus cystine to lysine ratio in diets for tambatinga fingerlings

Ciência e Agrotecnologia, 2021
Among a variety of hybrids produced in Brazil, tambatinga is obtained from the crossing of a tambaqui female with a pirapitinga male. Although rapid weight gain in less time is an attractive characteristic from a commercial viewpoint, the information on ...

The Antibody and Organ Immune Responses of Broiler Starter Fed Diets with Graded Levels of Digestible Lysine

Media Peternakan, 2014
The objective of the study was to investigate broiler immune responses during the starter phase to graded levels of digestible lysine. This experiment used 175 mixed sex broiler chickens from 1 to 21 days of age.

Utilization of ileal digestible amino acids by pigs: Lysine [PDF]

British Journal of Nutrition, 1990
Two experiments were conducted to determine the utilization of ileal digestible lysine by pigs. In the first, the apparent ileal digestibility of amino acids in cottonseed meal, meat-and-bone meal and soya-bean meal was determined in pigs fitted with‘T'-shaped cannulas.

Effect of amino acid deficiency on precaecal amino acid digestibility in broiler chickens

Journal of Animal Physiology and Animal Nutrition, 2019
AbstractIn this study, we determined whether deficient dietary amino acid (AA) concentrations influence the precaecal (pc) AA digestibility when determined using the regression approach. We mixed two basal diets. Basal diet 1 was deficient in essential AAs, whereas adequate AA concentrations were ensured in basal diet 2 by adding free AAs.

Available versus digestible amino acids – new stable isotope methods [PDF]

British Journal of Nutrition, 2012
The nutritive value of food protein sources is dependent on the amino acid composition and the bioavailability of the nutritionally indispensable amino acids. Traditionally the methods developed to determine amino acid bioavailability have focused on intestinal absorption or digestibility, which is calculated as the percent of amino acid intake that ...
