Abstract

The aim of the method is recommend a stable source of vitamin C for feed mixture to farmers. Simultaneously, inform about the influence of the pelleting of mixed feed on the stability of selected vitamins. Ascorbyl-2-monophosphate (Lutavit® C Monophosphate 35), tested in Institute of Animal Science in Prague, showed a high stability in mash and pelleted mixed feed during a guaranteed period of 12 weeks. Crystalline ascorbic acid is unstable and it is not suitable for incorporation into the complete mixed feed. Vitamin C protected by ethylcellulose (ROVIMIX® C-EC) and recommended to mixed feed showed greater losses than ascorbyl monophosphate. Ascorbyl monophosphate positively influenced the stability of vitamin E and A. Pelleting increased the retention of vitamin E and β-carotene in diets. The opposite was found in vitamins C and A.
