Challenge and Suggestion of Traditional Food Protein Nutritional Evaluation System

open access: yesLiang you shipin ke-ji, 2022
Protein is the one of the most important material basis of life. Insufficient or excessive protein intake and unbalanced amino acid intake will have a great impact on health.

Accretion Rates and Efficiency of Amino Acid Utilization during the Twenty-nine Days Post-Hatch Period in Male Ducks

open access: yesThe Journal of Poultry Science, 2012
The amino acid contents of whole body were determined in male ducks at 5 age intervals from d 1 to 29 post hatch. Whole body homogenates were analyzed of dry matter, nitrogen, and amino acids and used to determine amino acid accretion rates and ...

Initial assessment of protein and amino acid digestive dynamics in protein-rich feedstuffs for broiler chickens.

open access: yesPLoS ONE, 2020
A study evaluating apparent digestibilities of protein and amino acids and their corresponding digestion rates in four small intestinal sites in broiler chickens was completed to further investigate dietary optimisation via synchronised nutrient ...

Lysine levels in diets for broilers from 8 to 21 days of age

open access: yesRevista Brasileira de Zootecnia, 2013
This study was conducted to evaluate the effects of digestible lysine levels in diets with and without supplementation of industrial amino acids on performance and fat deposition in the carcass of broilers in the starter phase.

Protease Supplementation under Amino Acid Reduction in Diets Formulated with Different Nutritional Requirements for Broilers

open access: yesBrazilian Journal of Poultry Science, 2019
This study aimed to evaluate the effect of different reductions in digestible amino acids content (lysine, methionine, and threonine), according to two nutritional requirements in corn, soybean meal, and meat and bone meal based diets, with protease ...

Estimation of digestible sulphur amino acids requirements for growth performance and immune responses to Newcastle disease and avian influenza vaccination in broilers

open access: yesItalian Journal of Animal Science, 2021
This study was conducted to determine the effects of grower diet (d11-24) digestible sulphur amino acids (SAAs) levels on performance traits, blood metabolites, and immune responses to Newcastle disease (ND) and avian influenza (AI) vaccination in the ...

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

open access: yesJournal 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.

THE METABOLISM OF AMINO ACIDS AND CASEIN DIGEST IN PHLORHIZINIZED DOGS [PDF]

open access: yesJournal of Experimental Medicine, 1947
When solutions of sugar-forming amino acids are given parenterally or orally to phlorhizinized dogs, extra sugar and nitrogen are excreted in the urine. The route of administration does not influence the way in which the amino acids are metabolized.

Tryptic digestion of immobilized D‐amino acid oxidase

open access: yesFEBS 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.
