Influence of water soluble vitamins on the absorption of select exogenous amino acids in chickens
The aim of the study was to show whether water soluble vitamins contained in fodder may influence the absorption of exogenous amino acids from entrails. Tests were done on live broiler chickens (aged 2-4 months) in which the small intestine was looped. The physiological liquid included amino acids such as: L-threonine, L-valine, L-methionine, L-lysine, L-histidine, L-phenylalanine, L-leucine, L-isoleucine as well as amino acids with water soluble vitamins: thiamin, riboflavin, pyridoxine, nicotine acid, panthotenic acid, cholin, biotin, vitamin C and folic acid. The method of liquid chromatography before and 30 min after the flow through the loop was used to mark the concentration of amino acids in the perfusion liquid. The results of the study indicate a stimulatory effect of the vitamins on the absorption of amino acids in chickens. The influence on absorbing amino acids was highest when the water soluble vitamins were combined together in doses of 10 mg/l, 50 mg/l, 100 mg/l. A significant influence on the absorption of exogenous amino acids for threonine, valine, histidine and isoleucine observed after applying thiamin, riboflavin, cholin and biotin used in separated liquid. Changes in the absorption level of exogenous amino acids in relation to water soluble vitamins may have a stimulating influence on the development and growth in chickens.
