Lipoic acid and ascorbic acid affect plasma free amino acids selectively in the teleost fish pacu (Piaractus mesopotamicus)
(2004-11-01)
Most studies on the antioxidants, lipoic acid (LA) and ascorbic acid (AA), focused on species that, unlike teleost fish, are not scurvy-prone, and are able to synthesize AA. The antioxidant properties of LA may make it ...

Methionine to cystine ratio in the total sulfur amino acid requirements and sulfur amino acid metabolism using labelled amino acid approach for broilers
(2018-11-22)
Background: Assuming that part of Methionine (Met) is converted into Cystine (Cys), but ignoring the rates with which such phenomenon occurs may lead to an excessive supply of Met in poultry diets. Such inconvenient could ...
Assessment of the ideal ratios of digestible essential amino acids for pacu, Piaractus mesopotamicus, juveniles by the amino acid deletion method
(2021-02-01)
The present study aimed to determine the ideal ratios of digestible essential amino acids (EAAs) for pacu (Piaractus mesopotamicus) juveniles by the amino acid (AA) deletion method. A completely randomized design which ...
Whole-body amino acid pattern of juvenile, preadult, and adult pacu, Piaractus mesopotamicus, with an estimation of its dietary essential amino acid requirements
(2019-01-01)
In the present study, juvenile (live body weight, 54.3 ± 8.2 g), preadult (live body weight, 822.5 ± 33.9 g), and adult (live body weight, 1,562.8 ± 41.8 g) pacu, Piaractus mesopotamicus, were used to estimate their dietary ...
Establishing the optimal essential amino acid ratios in juveniles of Nile tilapia (Oreochromis niloticus) by the deletion method
(Wiley-Blackwell, 2016-04-01)
One of the strategies used to improve fish production is lowering the feed costs and the environmental impact by reducing dietary protein content. Using the deletion method, we determined the optimal amino acid (AA) ratio ...
Determination of digestible lysine and estimation of essential amino acid requirements for bullfrogs
(2017-01-20)
The traditional method to determine the nutritional requirements of animals is based on individual dose–response experiments that are time consuming and costly. One alternative to establish the dietary protein profile is ...
Lysine and methionine + cystine for laying hens during the post-molting phase
(2012-12-01)
One experiment was conducted to evaluate the effect of using different lysine and methionine + cystine levels on body weight recovery, performance, and egg quality of laying hens during the postmolting period. In this ...
