Efficiency of methionine and cystine utilization by broiler chickens using stable isotopes
(2020-01-01)
The aim of this study was to develop a method to determine the efficiency of utilization of Met and Cys using stable isotopes in order to reduce the number of sacrificed animals relative to the comparative slaughter ...
Utilization of amino acids and dipeptides by Lactobacillus plantarum from orange in nutritionally stressed conditions
(Wiley Blackwell Publishing, Inc, 2008-12)
To investigate amino acid and dipeptide utilization by Lactobacillus plantarum N4 isolated from orange peel, in a nutritionally depleted medium basedon MRS (Mann, Rogosa, Sharpe).Methods and Results: In MRS with 0 Æ1 g l)1 ...
Partitioning the efficiency of utilization of amino acids in growing broilers: Multiple linear regression and multivariate approaches
(2018-12-01)
Determining the efficiency of amino acid (AA) utilization in growing animals is crucial to estimate their requirement accurately. In broiler chickens, the composition of AA in feather is different from feather-free body ...
Evaluation of the optimum dietary essential amino acid pattern for adult pacu (Piaractus mesopotamicus)
(2021-07-15)
The optimum levels of essential amino acids (EAAs) are required to be maintained in fish feed for obtaining normal body protein synthesis and muscle growth. This study aimed to determine the optimum dietary EAA pattern for ...
Modelling broiler requirements for lysine and arginine
(2021-10-01)
Six assays were conducted to investigate male and female broiler responses to standardized ileal digestible (SID) lysine (Lys) and arginine (Arg). Response data were modeled to estimate the efficiency of utilization (k) ...
A procedure to evaluate the efficiency of utilization of dietary amino acid for poultry
(Editora da Universidade Estadual de Maringá (EDUEM), 2014-06-01)
The aim of this study was to develop a procedure based on Gompertz function to determine the efficiency of utilization of amino acid. The procedure was applied to determine the efficiency of utilization of dietary lysine, ...
The optimal digestible valine, isoleucine and tryptophan intakes of broiler breeder hens for rate of lay
(Elsevier B.V., 2018-04-01)
Three concurrent assays were conducted with objective of to evaluate the response of broiler breeder hens to valine (Val), isoleucine (Ile), and tryptophan (Trp) intake, determine amino acid utilization efficiency (k), and ...
The cysteine, total sulfur amino acid, tyrosine, phenylalanine plus tyrosine, and non-essential amino acid maintenance requirements of broiler breeders
(Oxford Univ Press, 2016-06-01)
Two hundred and fifty Cobb-Vantress broiler breeders were used to determine the maintenance requirement and efficiency of utilization of dietary Cys, Tyr, and non-essential amino acids (AA) in a 21-day experiment. The ...
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 ...
Response of Nile tilapia (Oreochromis niloticus) to lysine: Performance, body composition, maintenance and efficiency of utilization
(2021-05-30)
The purpose of the three trials reported here was to measure the efficiency of lysine utilization for growth and lysine requirement for maintenance of Nile tilapia (Oreochromis niloticus) during three growing stages. For ...
