Понеже някои се присмяха на споменатото от мен рибено брашно (fish meal) ще цитирам някои неща по-скоро като инфо за колеги-експериментатори.
Ето какво пише в тази книга: http://books.google.bg/books/about/E...AJ&redir_esc=y
Ето какво пише тук: http://www.google.com/patents/WO1994017674A1?cl=enThe sources, costs and compositions of various pollen substitutes are compared. Pacific herring meal is cheaper, and its protein content higher than that of any other pollen substitute that has been considered. It may be readily diluted to the 23% protein level considered optimal for honeybee brood rearing by adding cane sugar, and it is particularly rich in lysine and arginine, and in B vitamins. Preliminary trials by the author, using small patties placed on the brood nest, indicated that fish meal was readily accepted. Colonies remained in good condition throughout the trials.
Откъси и от други изследвания:Typically, substitutes proposed to date include one or more of the following proteins:- soy flour, lactic yeast, brewers' yeast, torula yeast, skimmed milk powder, casein, and fish meal. U.S. Patent 4,386,107 describes a pollen substitute in which a mixture of lactic yeasts, vegetable protein and egg protein is proposed. However, it has been found that while some proteins appear useful, others of similar composition inexplicably have been
unsuitable or even fatal. For example fish meal has been reported to be satisfactory while meat meal, linseed meal and peanut meal have not. Pea-protein and rapeseed meal have given discouraging results.
