The disappearance of total N, non-protein-N and amino acid-N after washing, rumen incubation and intestinal passage of sugarbeet pulp, maize-gluten feed, maize feed meal, palm kernel meal, soyabean hulls, soyabean meal, grass silage, maize silage and concentrate was measured in four dairy cows using nylon-bag techniques. Disappearance of amino acid-N after washing varied between feedstuffs from...

The nutritional value of six tropical seaweeds (Sargassum wightii, Ulva lactuca, Kappaphycus alvarezii, Hypnea musciformis, Acanthophora spicifera and Gracilaria corticata) as complementary source of dietary proteins for human and animal nutrition based on amino acid profile was evaluated. All these species showed similar non-essential amino acid patterns in which aspartic and glutamic acids co...

Fasting plasma and urinary amino acid concentrations were studied under carefully controlled conditions in 22 children with Down's syndrome and in age matched controls. The only significant difference between the groups was a higher mean plasma lysine concentration in Down's syndrome patients compared to controls.

MOTIVATION The observed correlations between pairs of homologous protein sequences are typically explained in terms of a Markovian dynamic of amino acid substitution. This model assumes that every location on the protein sequence has the same background distribution of amino acids, an assumption that is incompatible with the observed heterogeneity of protein amino acid profiles and with the suc...

effects of different levels of dietary nucleotides (nt) were studied on muscle amino acid profile of rain bow trout with an average weight 11.35±0.32 over 8 weeks. this experimental was carried out in 700 l circular tanks with 40 fish per tank. nt was added to the diet at the rates of 0.0, 0.05, 0.1, 0.15 and 0.2%. fish were fed 5 times a day at a rate of 3-5% body weight. after 8 weeks of feed...

In this study rainbow trout (Oncorhynchus mykiss) fillets were vacuum packed, frozen and stored at -18°C and  the effect of this packaging method on proximate composition, fatty acids and amino acid profile and their changes compared to control conditions during 9 months of storage were studied. The results showed that 18 fatty acids were identified. The unsaturated fatty acid (UFA) were 56.77 ...

The protein content and amino acid profile of Anchote (Coccinia abyssinica) leaves and tubers were determined from ten different accessions taken from Debre Zeit Agricultural Research Center, Ethiopia. Crude protein content was determined by Kjeldahl method and amino acid profile was analyzed using performic acid oxidation and acid hydrolysis by ninhydrin-derivatized analysis with amino acid an...

an experiment was conducted to reevaluate the digestible lysine requirement of arian male broilers by comparing the performance of chicks fed different levels of cottonseed meal (csm) on a total amino acid (aa) versus a digestible aa basis. four hundred and thirty two (432) arian male broiler chicks were allotted to 18 treatments with four repli-cates of six chicks each in a completely randomiz...
