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, methionine+cystine and threonine by growing pullets and based on the efficiencies were estimated the requirements for the growth phase of birds. The Gompertz function was fitted to the data of feed intake, body weight, feather-free body protein weight and feather protein weight of four strains of laying hens in the growth phase. The rates of consumption and daily protein deposition (PD) were calculated. The amino acid deposition was obtained by multiplying the PD by the amino acid concentration in feather protein and feather-free body...

Animal performance and carcass characteristics from confined lambs fed on concentrate feed and additives Anais da ABC (AABC)
Prado,Tayrone F.; França,Aldi F.S.; Meirinhos,Maria Lúcia G.; Peron,Hugo J.M.C.; Ferreira,Reginaldo N.; Oliveira,Leonardo G.; Corrêa,Daniel S..
ABSTRACT The number of sheep flocks in Brazil is increasing. It is known that lambs must be slaughtered when young for producing quality meat. The current study evaluated the inclusion of protected methionine, protected lysine, lysophospholipid and amylolytic enzymes in a diet to lambs and their effects on weight gain and quantitative carcass traits at slaughtering. Eighty non-castrated male crossbred Dorper x Santa Inês lambs, 20.57 ± 4.33 kg live weight, were used. The feedlot lasted 64 days and 60 animals were slaughtered. There were no differences for live weight, daily feed intake, feed conversion and average daily weight gain at the first 28 days of feedlot. From the 28th day lysophospholipid treatment presented the highest live weight....

ARCHER DANIELS MIDLAND: PRICE FIXER TO THE WORLD AgEcon
Connor, John M..
Both market structure and corporate practices of Archer Daniels Midland fostered the implementation of the largest price- fixing conspiracies seen in modern times. These events have spurred renewed attention by U.S. antitrust authorities in prosecuting international cartels. The overcharges imposed on buyers of lysine and citric acid during 1994-1995 by ADM and its co-conspirators amounted to at least $200 million, and the total amount of public penalties, private damages, and legal costs exceeds $500 million. Perpetrators of price-fixing now face monetary exposures that are five times the amount of the harm caused to buyers.

Are high-lysine cereal crops still a challenge? BJMBR
Ferreira,R.R.; Varisi,V.A.; Meinhardt,L.W.; Lea,P.J.; Azevedo,R.A..
The essential amino acids lysine and threonine are synthesized in higher plants via a pathway starting with aspartate that also leads to the formation of methionine and isoleucine. Lysine is one of most limiting amino acids in plants consumed by humans and livestock. Recent genetic, molecular, and biochemical evidence suggests that lysine synthesis and catabolism are regulated by complex mechanisms. Early kinetic studies utilizing mutants and transgenic plants that over-accumulate lysine have indicated that the major step for the regulation of lysine biosynthesis is at the enzyme dihydrodipicolinate synthase. Despite this tight regulation, recent strong evidence indicates that lysine catabolism is also subject to control, particularly in cereal seeds. The...

Determination of aspartate kinase activity in maize tissues Scientia Agricola
Ferreira,Renato Rodrigues; Vendemiatti,Ariane; Gratão,Priscila Lupino; Lea,Peter John; Azevedo,Ricardo Antunes.
Lysine, threonine, methionine and isoleucine are synthesized from aspartate in a branched pathway in higher plants. Aspartate kinase plays a key role in the control of the aspartate pathway. The enzyme is very sensitive to manipulation and storage and the hydroxamate assay normally used to determine aspartate kinase activity has to be altered according to the plant species and tissue to be analyzed. We have optimized the assay for the determination of aspartate kinase in maize plants callus cell cultures. Among all the assay parameters tested, the concentration of ATP/Mg and temperature were critical for enzyme activity. In the case of temperature, 35°C was shown to be the optimum temperature for aspartate kinase activity.

Diet formulation techniques and lysine requirements of 1- to 22-day-old broilers Rev. Bras. Ciênc. Avic.
Siqueira,JC; Sakomura,NK; Dourado,LRB; Ezequiel,JMB; Barbosa,NAA; Fernandes,JBK.
Two experiments were carried out to compare two techniques (amino acid supplementation and dilution) for formulating experimental diets for pre-starter (1 to 8 days) and starter (8 to 22 days) broiler chicks and to estimate digestible lysine requirements using the dose-response method. In each experiment, 1,200 male Cobb 500 chickens were randomly distributed according to a 5x2 factorial arrangement (lysine level x formulation technique) with six replicates of 20 birds each. For the supplemented diet, a basal diet was formulated to meet the nutritional requirements, then L-lysine HCl was added to achieve digestible lysine levels of 0.975, 1.082, 1.189, 1.296 and 1.403% in the pre-starter diets and 0.840, 0.932, 1.024, 1.116 and 1.208% in the starter diets....

Dietary lysine requirement of adult lambari ( Astyanax altiparanae ) (Garutti and Britski, 2000) R. Bras. Zootec.
Campelo,Daniel Abreu Vasconcelos; Salaro,Ana Lúcia; Ladeira,André Luis Fialho; Moura,Lorena Batista de; Furuya,Wilson Massamitu.
ABSTRACT A 90-day feeding trial was conducted to estimate the dietary lysine requirement of adult lambari ( Astyanax altiparanae ), based on growth performance, whole-body composition, muscle development, and aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities. Six isoproteic (345.0 g kg−1) and isoenergetic (19.51 MJ kg−1) diets were formulated, and crystalline L-lysine was added to obtain diets with lysine concentrations of 12.13, 13.31, 15.36, 18.79, 19.92, and 23.02 g kg−1 dry diet. Female adult lambari (n = 480; weight of 4.96±0.02 g) were distributed into 24 (70 L) aquaria and fed the experimental diets six times daily. Fish fed 12.13 to 19.92 g kg−1 lysine showed increased weight gain and percent weight gain, and fish from...

Distribution of soluble amino acids in maize endosperm mutants Scientia Agricola
Toro,Alejandro Alberto; Medici,Leonardo Oliveira; Sodek,Ladaslav; Lea,Peter John; Azevedo,Ricardo Antunes.
For human nutrition the main source of vegetable proteins are cereal and legume seeds. The content of total soluble amino acids in mature endosperm of wild-type, opaque and floury maize (Zea mays L.) mutants were determined by HPLC. The total absolute concentration of soluble amino acids among the mutants varied depending on the mutant. The o11 and o13 mutants exhibited the highest average content, whereas o10, fl3 and fl1 exhibited the lowest average content. In general, the mutants exhibited similar concentrations of total soluble amino acids when compared to the wild-type lines, with the clear exception of mutants o11 and fl1, with the o11 mutant exhibiting a higher concentration of total soluble amino acids when compared to its wild-type counterpart...

Effect of different digestible isoleucine/lysine ratios for broiler chickens R. Bras. Zootec.
Tavernari,Fernando de Castro; Lelis,Guilherme Rodrigues; Carneiro,Paulo Roberto de Oliveira; Vieira,Rodolfo Alves; Polveiro,Richard Costa; Luengas,Jorge Armando Prada; Rostagno,Horacio Santiago; Albino,Luiz Fernando Teixeira.
Two experiments were conducted to evaluate different digestible isoleucine/lysine ratios on diets for broiler chickens in the starter (7 to 21 days) and finishing (30 to 43 days) phases. For the tests, the experimental design was of randomized blocks with seven treatments (six different digestible isoleucine/lysine ratios and a control treatment) and eight repetitions of 25 and 20 birds (COBB males) per experimental unit in the starter and finishing phases, respectively. The diets met the requirements, except for isoleucine and lysine. To avoid excess lysine in the experimental diets, the digestible lysine content was calculated to be 87% and 89% of the recommended for the starter and finishing phases, respectively. The control treatment was adequate in...

Effects of lysine levels of diets formulated based on total or digestible amino acids on broiler carcass composition Rev. Bras. Ciênc. Avic.
Nasr,J; Kheiri,F.
The study was conducted to evaluate carcass yield and chemical composition of thigh and breast muscles of broilers fed three different lysine requirement levels: high lysine (+10% NRC), standard (NRC) and low lysine (-10% NRC) and two ways of expressing amino acids in feedstuffs (total or digestible amino acids). The results of this study showed that diet formulation based on digestible amino acids significantly influenced breast yield and abdominal fat deposition. The study showed that increasing lysine level (+10% NRC) of diet significantly increased both carcass and breast percentage and also carcass, breast and thigh weight. The interaction between digestible amino acids and lysine requirement levels affected carcass and breast percentage. Feeding...

Energy and lysine for broilers from 44 to 55 days of age Rev. Bras. Ciênc. Avic.
Araújo,LF; Junqueira,OM; Araújo,CSS; Barbosa,LCGS; Ortolan,JH; Faria,DE; Stringhini,JH.
An experiment was conducted to evaluate the performance and carcass yield of broilers at 55 days of age fed diets with different levels of metabolizable energy and lysine. Evaluated data of performance were weight gain, feed intake, energy intake, lysine intake, caloric conversion and feed conversion. Carcass assessment was performed based on data from carcass yield, breast weight, whole wings, whole legs, back, head + neck, feet and abdominal fat. A 3 x 3 factorial arrangement was used, with 3 levels of metabolizable energy (3,200; 3,400 and 3,600 kcal ME/kg) and 3 lysine levels (0.95%; 1.05% and 1.15%). There was no interaction between the two factors. Nevertheless, increasing levels of metabolizable energy improved weight gain (745 g; 841 g and 910 g,...
