Estimating endogenous amino acid flows at the terminal ileum and true ileal amino acid digestibilities in feedstuffs for growing pigs using the homoarginine
, b-ODAP, and asparagine contents of grass pea landraces cultivated in Turkey.
(hArg), asymmetric dimethylarginine (ADMA) and symmetric dimethylarginine (SDMA) were measured by high-performance liquid chromatography (HPLC).
Recent studies have shown that patients with low plasma homoarginine
are at increased risk of stroke, myocardial infarction and heart failure (HF).
For FAA analysis, 100-mg samples were first extracted with 7% trichloroacetic acid, containing homoarginine
as an internal standard, then the extracts were washed with diethyl ether to remove trichloroacetic acid (Konosu et al.
In PF and PE, diets and ileal digests, chromic oxide was determined by atomic absorption, total and reactive lysine after reaction of these materials with O-methylisourea to form homoarginine
by high pressure liquid chromatography.
Evaluation of the furosine and homoarginine
methods for determining reactive lysine in rumen-undegraded protein.
The procedures, including the homoarginine
technique, the feeding enzymehydrolyzed protein and the isotope-dilution technique, are used for estimating the total endogenous losses of AA (Hodgkinson et al.
The effect of dietary homoarginine
derived from guanidination of synthetic lysine on endogenous amino acid loss and apparent and true ileal amino acid digestibility in the pig.
T] include the homoarginine
method (Rutherfurd and Moughan, 1990) and isotope tracer dilution techniques (de Lange et al.
