摘要

Because of the busy fall season, it sounds like some producers didn't have time to double check feed stores, and are concerned about adequate feed this winter. For those concerned about hives being light, and the colonies are wintered indoors, the best course of action is to feed in early spring or late winter. If hives are wintered outdoors, then be sure to take advantage of any early break in winter, say in early March, and check and feed if necessary, Of course it's important not to disturb colonies too much and to use good judgement in working hives when conditions are not ideal. Regarding the quality of winter feed, Dr. Rob Currie says that "high quality high-fructose corn syrup (HFCS) should be clear and colourless. Noticeable yellowing is a cause for concern and could be correlated with increases in acidity and/or hydroxymethylfurfural (HMF) that would make the feed undesirable to use as a winter food source." HMF content will increase with temperature and time.
