Effect of reducing 3.2% dietary protein level on the growth performance and immunity of Nile tilapia (Oreochromis niloticus) with supplementation of multi amino acids
Reducing dietary protein content in fish feeds will reduce cost of production if growth performance can be maintained. In this study, we assessed the effects of reduced dietary protein content from 33.5% to 27.4% with ideal amino acids profile on the growth, immune parameters, intestinal microvilli length and total ammonia nitrogen discharge of tilapia. After 8 weeks of feeding, growth performa...
متن کاملMetal-Ion-Coordinating Properties of Various Amino Acids, Investigation of the Essential Function in Biological Systems regarding to their Nano-Structure
The acidity constants of some amino acids (Am) were determined by potentiometric pH titration. The stability constants of the 1:1 complexes formed between M2+: Ca2+, Mg2+, Mn2+, Co2+, Ni2+, Cu2+ or Zn2+ and Am2-, were determined by potentiometric pH titration in aqueous solution (I = 0.1 M, NaNO3, 25°C). The order of the stability constants was reported. It is shown that the stability of the bi...
متن کاملUptake and nitrate accumulation affected by partial replacement of nitrate-N with different source of amino acids in spinach and lettuce
As natural plant growth stimulators, amino acids are widely used to improve the yield and quality of crops. Change in enzymes activities of N assimilation (NR, NiR and GS), residual nitrate (NO3-), soluble protein content, and yield of spinach and lettuce plants were investigated under replacing 20% nitrate-N in the nutrient solution by L-glycine and blood meal amino acids. Seeds of the mention...

متن کاملبررسی اثرات اسیدهای آمینه بر رشد ترایکوفیتون روبروم و ترایکوفیتون ورکوزوم
Background: Amino acids have different effects on the growth of dermatophytes. Some may encourage growth while others may inhibit it. These effects not only depend on the type of the amino acid but also on the amino acid concentration and type of the dermatophyte. The aim of this study was to investigate the effects of amino acids on the common dermatophytes in Iran.Methods: In this experimenta...
