ABSTRACT:
BACKGROUND OF THE INVENTIONS
Properly feeding animals, particularly farm animals, is absolutely critical for maintaining health and maximizing growth and production. In addition to the obvious requirements of protein, starch and fats, animals must receive additional nutrients in substantially lesser amounts. These nutrients such as minerals and vitamins are absolutely critical for the health of the animals. Unfortunately, animals will not feed on a 100% nutrient composition in the correct amounts. Therefore, the nutrients must be provided to the animals in a way so that the correct amounts are consumed.
One way to provide the nutrients to the animal is to mix them with the other feed ingredients that provide protein, starch and fat. Premixes of minerals and vitamins can be obtained and added to the bulk feed of the animal. Generally these are combinations of free flowing meals and powders of different sizes, shapes and densities. These nutrient products do not remain suspended in the bulk feed and tend to separate. Further, it is difficult to keep these mixed adequately to maintain an even concentration of a nutrient throughout the bulk feed. Another disadvantage is that the nutrients separate from each other both in bulk and in the feed because of the different sizes, shapes and densities.
A solution to this is to form processed feed particles which includes nutrients. However, for many farmers to invest in the manufacturing process to produce these products is cost prohibitive.
Bulk feed supplements which are over 26% protein and which farmers can feed to animals with other grain products are also known. But these are used at high concentration and are designed to be an animal's protein source and nutrient source. No care was ever given to maintaining these suspended in bulk feed.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a method to combine nutrients with bulk feed for farm animals. More particularly, it is an object of the present invention to provide such a mechanism whereby the nutrient supplement remains suspended in the feed to ensure desired concentration levels are maintained.
The objects of the present invention are obtained by forming pellets which have a high concentration of the nutrients in combination with a carrier and, if necessary, a lubricant and/or a binder. The pellets are then rolled to a size which is approximately equal to or greater than the size of the average particle size of the bulk feed. When combined with the feed, these particles, due to their size and approximate density, remain suspended in the feed and do not separate as easily over prolonged periods of time.
This provides an effective, efficient way to supply nutrients to farm animals. Further, due to the convenience, different nutrient pellets can be formulated for a variety of different animal needs such as lactating or nonlactating cows, young animals, older animals, chickens, turkeys, and so on.
The objects and advantages of the present invention will be further appreciated in light of the following detailed description.
