POLLEN
SUPPLEMENTS AND SUBSTITUTES
Pollen is the principal source of proteins, vitamins, lipids and
minerals for honey bees. Feeding pollen supplement or
substitutes is one of the best beekeeping practices to
encourage colony growth. A pollen substitute is any material
that can be fed to colonies to replace its need for natural
pollen. A pollen supplement is a pollen substitute that
contains about 10 % natural pollen (dry weight basis). A
pollen supplement can best be described as a pollen
extender. Among the most commonly used protein sources are
soybean meal, brewer's yeast, low-lactose whey (dried) and Torula yeast. Pollen substitutes and extenders can be fed in
a moist patty, or dry. If fed in a patty, it should be
placed as close as possible to the combs containing unsealed
brood. Dry materials can be fed in a feed-lot system but
this requires protection from adverse weather conditions and
good foraging conditions.
The are numerous recipes for both pollen substitutes and pollen
supplements. The following recipes (modified from The
Encyclopedia of Beekeeping, 1985) are a sample and are given
in parts by weight, for dry mixes and moist patties, as
appropriate.
