Effects of Some Novel Thiamine Derivatives in Chickens

Abstract

The present experiment was designed to compare the effects of thiamine chloride hydrochloride (B-HCL) and its derivatives, thiamine propyldisulfide (TPD), thiamine tetrahydrofurfuryldisulfide (TTFD) in chickens.The first experiment was performed to examine the replacing possibility of thiamine derivatives to thiamine in the test of body weight, egg laying ability, fertility ratio and hatchability as well as to examine thiamine content transported into egg and liver.Generally speaking, better results were obtained in the use of thiamine derivatives than that of thiamine, and this tendency was most remarkable in the case of thiamine propyldisulfide. With respect to the transportation of thiamine into egg and liver, no difference was found among trials in case of egg, but thiamine volume decreased in all trials. In case of liver, thiamine content was less in the derivatives trial than in thiamine trial.The second experiment was performed to examine the influence of thiamine propyl disulfide added to the diet of mother chickens on the growth of chicks. Female chickens that were fed on the standard diet into which various levels of thiamine derivatives added (1mg, 5mg, 5mg/kg: increased by every other week) were inseminated to male chickens that were fed on the standard diet. The growth of chicks was compared from day old to four weeks.Chicks hatched from 5mg group showed better growth than that of other groups. Unfavorable influence was not found in case of an excessive addition of thiamine derivatives.
