ABSTRACT
The present study included 2 trials which were performed to investigate in which way graded vitamin B6 supplies or vitamin B6 deficiency would influence the chemical composition of the whole body, the liver, pectoral muscle or the eggs of hens and in which way it might change the pattern of amino acid composition in the proteins of the pectoral muscle. The following results were obtained No direct changes in the protein and fat content of the birds (total body, liver, pectoral muscle) were noted in trial 1 when graded amounts of vitamin B6 were supplied, whereas in trial 2 signifikant increases in the fat content of the body and decrases in the protein levels were observed when vitamin B6 supplements were added to a vitamin-deficient diet (pair-fed group) or fed to animals receiving increased amounts of food (controls). Variations in dietary vitamin B6 concentrations did not produce statistically significant changes in the protein and fat content of eggs, and in the pattern of amino acid composition of proteins in the pectoral muscle. However, with increasing vitamin B6 uptake, the serine to glycine ratio was narrowed.
