SUMMARY OF THE INVENTION
The invention relates in general to nutritional compositions and formulations that provide honey bees with a fully nutritious, easily digestible, complex mixture of nutrients in amounts and proportions effective to support growth and development of honey bees, sustain brood rearing, and maintain hive vigor. More specifically, the invention relates to nutritional compositions and formulations that utilize corn gluten and at least one other source of protein and lipid content.
The inventors have discovered that
providing multiple sources of protein and lipids, including corn gluten, leads to improved honeybee health and longevity. The combination of proteins, lipids, and carbohydrates benefits the colony by providing the food source necessary to develop colony strength and as well as to maintain a high and healthy brood production. The high quality and excellent palatability of the compositions of the invention are especially suitable for fall, winter or early spring feeding. In addition, the compositions of the invention offer commercial operations, queen breeders and hobbyist beekeepers an excellent tool to boost colony strength, population, and brood production for a more effective pollination season and potentially higher honey yields.
In one embodiment, the artificial diet formulation includes about 20-80% protein derived from at least two sources including corn gluten, about 1-7% lipid derived from at least two sources including corn gluten, and about 10-90% carbohydrate. The inventors have found that particles in the formulation preferably are less than 35 microns in diameter. The relatively small diameter of the particles (compared to other artificial bee diets) is thought by the inventors to be important in the improvement of the absorption and the conversion to usable food reserves during the digestive process.
In another embodiment of the invention, the diet further includes protein derived from one or more of soy concentrate, barley flour, yeast, or corn distillers dried grains. Similarly, the lipids of the diet may be derived from one or more of soy concentrate, barley flour, yeast, or corn distillers dried grains.
In some embodiments, the diet preferably is a liquid diet that includes high-fructose corn syrup as the carbohydrate source. The diet also may be formulated in dry form and mixed with a sugar syrup prior to use to form a liquid. Alternatively, a patty or a dry formulation or may be formed by using less syrup or a solid carbohydrate source and bringing the product to a dough like or powdery consistency that is placed in the colony for the bees to eat.
Preferably, formulations of the invention further include about 3-6% ash, about 2-5% citric acid, and about 1-2% antifungal agent in order to have suitable acidity and stability. Also preferably, formulations of the diet is substantially free of egg-derived protein. The inventors have found that previous bee diet compositions containing egg can be difficult for the bees to digest, perhaps due to the high lipid content of eggs. Moreover, because of the high fat levels, the inventors have found that egg-containing product is more prone to deteriorate and oxidize over time and consequently lose its nutritional value.
In other embodiments of the invention, the diet is formulated to include about 40-60% protein derived from at least two sources including corn gluten, about 1-5% lipid derived from at least two sources including corn gluten, and about 40-60% total carbohydrates, of which typically 0.4% are digestible carbohydrates, about 3-6% ash, and about 2-5% citric acid, with at least a majority of the particles in the formulation being 35 microns in diameter or less.
In still other embodiments of the invention, the diet is formulated to include about 40-60% protein derived from at least three sources including corn gluten, soy concentrate, and barley flour, about 2-4% lipid derived from at least two sources including corn gluten, about 40-60% carbohydrate, of which typically 0.4% are digestible carbohydrates, about 3-6% ash, and about 2-5% citric acid, with a majority of the particles in the formulation being less than 35 microns in diameter.
The invention also comprises methods of making and using the artificial diets and diet formulations. The diets of the invention provide a complex mixture which includes proteins, lipids, carbohydrates, minerals, and other nutrients to provide all the dietary requirements for bees to rear multiple generations of young bees when there is an absence of natural pollen and nectar. The formulations are pH balanced to mimic the pH of natural pollen and promote a healthy gut environment in the bees. Optionally, anti-microbial agents may be included to prevent pre-mature deterioration of the diet.
The combination of ingredients in the diet formulations assure that a smooth, evenly mixed, substantially homogeneous, non-clumping mixture is obtained when the dry formulation is mixed with a liquid and that the formulation is palatable to bees and provides bees nutrients to raise multiple generations of young bees.
