Název v původním jazyce

The stability of vitamin C and other vitamins in the diets of breeding hens

Popis výsledku v původním jazyce

The stability of vitamin C in mash and pelleted mixed feed was studied. Feed without the addition of ascorbic acid (AA) and mixed feed supplemented with 200 mg/kg AA in the form of crystalline or protected AA (Lutavit? C Monophosphate 35) were analysed.The interaction between the source of vitamin C and the pelleting (P<0.001), between the source of vitamin C and the storage time (P<0.001) and the combined effect of the pelleting and the storage time (P<0.001) was ascertained in the vitamin C content in the feed mixture. Monophosphate was highly stable in the mixture until the 10th week of storage and seems to be an appropriate source of vitamin C in animal feed. In contrast, crystalline AA had notably low stability. The process of pelleting of the diet had a different effect on the stability of the monitored vitamins. During storage, the stability of vitamin C and retinol was lower and ?-tocopherol and ?-carotene stability was higher in the pelleted feed than in the non-pelleted feed
