| description | Feed supplements containing B-vitamins are marketed as having a calming effect on nervous horses, improving the function of the hindgut, easing the change of coat and increasing the growth and quality of hoofs. The aim of this literature study was to review whether and when horses have a requirement of B-vitamin supplements, and if studies can validate the statements used in the marketing. Since the middle of the 20th century, studies have shown that thiamine, riboflavin, niacin, pantothenic acid, pyridoxin, folic acid, biotin and cobalamin are synthesised in the colon of the horse. Apart from in experimental studies with B-vitamin deficient diets, clinical symptoms of vitamin B deficiency have never been reported in horses. A calming effect of thiamine supplementation on nervous horses has both been proven and disproven in studies, but an orally supply of the vitamin has not shown any calming effect. Feeding horses high doses of biotin have shown positive results in the growth and quality of the hoof horn. Using B-vitamin supplements for improving the function of the hindgut and easing the change of coat has not been investigated in studies and the statements used in marketing can therefore not be validated. |

Fodertillskott innehållande B-vitaminer marknadsförs som att de har lugnande effekt på nervösa hästar, främjar en god grovtarmsfunktion, underlättar vid pälsbyte samt ökar tillväxt och kvalitet på hovhorn. Denna litteraturstudie syftar till att undersöka om och i så fall när hästar har ett behov av B-vitamintillskott, samt om studier kan styrka marknadsföringens påståenden. Redan i mitten av 1900-talet visade studier att B-vitaminerna tiamin, riboflavin, niacin, pantotensyra, pyridoxin, folsyra, biotin och kobalamin syntetiseras i hästens tarmkanal. I andra fall än under foderförsök har kliniska symptom på B-vitaminbrist aldrig rapporterats. Tiamins effekt av att lugna nervösa hästar har både påvisats och motbevisats i studier, men någon lugnande effekt av oralt tillförd tiamin har inte visats. Utfodring av biotin i höga doser har visat positiva resultat på hovhornets tillväxt och kvalité. Användning av B-vitamintillskott för förbättrad grovtarmsfunktion och för att underlätta vid pälsbyte har inte undersökts i studier och marknadsföringens argument kan därför inte styrkas.
