[Thiamine allowance of animals receiving rye and wheat grains grown with the use of herbicides from the phenoxy acid chlorine derivative group].

Investigations carried out for several years have shown that the treatment of rye and wheat crops with an amine salt of 2,4-dichlorophenoxyacetic acid and dialene produces sometimes a decrease in the grain thiamine content of these cereals. Feeding of rye and wheat grains grown with the use of the amine salt of 2,4-dichlorophenoxyacetic acid to growing ratlings has demonstrated that the thiamine content in the liver of ratlings is directly proportional to thiamine supply to their body with food.
