Please post what information you have on the RIGHT fat content, Adony (or
where to get that information). I posted that question previously and if I
recall the replies correctly, non fat soyflour was too low, and full fat
soyflour was too high. Brewers yeast has no fat, so one could obtain the
optimum fat content by adjusting the soyflour percentage and/or using a
mixture of full fat / non fat soyflour.
Here are some interesting (to me) facts from Hive and Honeybee:
-Bees do not need lipids (fats) or indeed even pollen in order to
synthesize or secrete wax.
-Sterols are nonsaponifiable fats (don't make soap in alkali). Man can
manufacture cholesterol from fats, but many insects can't and must obtain
them in their diet for normal growth
-"Gontarski (1954) showed that young bees feeding on sugar solution alone
showed considerable development of the abdominal fat bodies" (so they were
manufacturing some fat from sugars).
-"The incorporation of corn oil in the basic bee diet (Haydak and Dietz,
1965) did not result in increases in brood rearing activity, hypopharyngeal
gland development or the average dry weight of emerging bees reared on the
test diet. It was concluded that adult honey bees do not require require
supplementary lipids."
-Phospholipids were found to inhibit feeding.

Stan
