Abstract
Samples of 1st and 5th cutting baled alfalfa hay from the same stand were collected weekly for 18 wk to determine the effect of storage on concentrations of tocopherols and carotene. There was a loss of tocopherol and carotene during storage for 1st cutting hay, but not for 5th cutting hay. The difference in the initial concentrations between 1st and 5th cutting hay was significant for tocopherol, but not for carotene. These differences were attributed to the difference in moisture content. The practical importance to the dairy farmer is questionable.Keywords
