Redução do nível protéico da dieta, através da formulação baseada em aminoácidos digestíveis Protein levels reduction of broilers in the initial phase

open access: yesCiência Rural, 2004
Um experimento foi conduzido para estudar a redução do nível protéico da dieta, através da formulação baseada em aminoácidos digestíveis, de frangos de corte na fase inicial. Foram utilizados 800 pintos machos, Cobb, as quais foram pesados e distribuídos

Effects of increasing crystalline lysine and dietary fat on finishing pig growth performance [PDF]

open access: yes, 2003
A total of 1,024 barrows (each initially 157 lb, PIC L337 x C22) were used in a 28-d study to evaluate the effects of increased crystalline amino acids (none versus 4.5 lb/ton of L-lysine HCl plus L-threonine to maintain the proper ratio relative to ...

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.

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.

Single-phase feeding and compensatory growth in growing and finishing pigs (OK-Net Ecofeed Practice Abstract) [PDF]

open access: yes, 2020
• Limit the supply of essential amino acids during early growth and utilise the pigs’ capacity to fully compensate for the restriction by increased protein retention and faster growth during later growth phases.

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 ...

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

open access: yesBritish 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.
