The main effect of chromium on amino acids is to promote the entry of amino acids into cells, thus improving protein synthesis.
Chromium binds to pyrophosphates, nucleoproteins, glycine, methionine and serine in animal blood, accelerating the entry of these amino acids into cells, promoting intracellular protein and nucleic acid synthesis, prompting partial utilization of urea nitrogen in blood as a nitrogen source for amino acid and protein synthesis, and enhancing protein synthesis and deposition.
Chromium is more abundant in nucleic acids, affecting the synthesis of nucleoproteins, RNA and nucleic acids, protecting RNA from thermal denaturation, and helping to maintain the structural integrity and stability of nucleic acids.
The addition of yeast chromium to broiler duck diets reduced dry matter excretion by 15.52%, reduced protein excretion by 9.72% and increased nitrogen retention.
