1. Technical Field of the Invention
This invention generally relates to bovine health, primarily to the prevention of “Hardware Disease” in cattle, and secondarily to prevention of toxic Al blood and bone poisoning, thirdly to strengthening of bones, fourthly to healthy red blood cells.
2. Description of Prior Art
Cows have been known to accidentally eat fencing staples, bailing wire remnants, nails, etc. while grazing. Cow magnets are administered orally to cows to attract and retain ferrous material within the Rumen (upper stomach). The magnet is heavy enough to prevent passage from the Rumen. The magnet remains in the Rumen collecting iron pieces and particles and retaining them within the Rumen for the entire life of the cow. Retention of sharp iron pieces within the Rumen greatly reduces the possibility of damage to other more delicate, vital organs. Damage to intestines, organs, etc. caused by ingestion of iron objects often causes the animal to stop eating and eventually expire. The cause of death is then categorized by veterinarians as “Hardware Disease.” Various types of cow magnets have been available over the past forty years and have contributed greatly to the prevention of Hardware Disease.
Heretofore cow magnets have appeared to be made of non-toxic metals. They have however not adequately fulfilled the necessity for the magnet to be non-toxic to the cow. They also have not been made of minerals to supplement the cow's health. Prior art suffers as follows:
The following charts (deleted available upon request) first show Aluminum toxic levels. Later under advantages we compare Aluminum with Strontium toxic levels, according to the ATSDR. Allowable levels of these two minerals before becoming seriously toxic are:
1) Al serious toxic levels average 350 mg/kg of body weight/day
2) Sr serious toxic levels average 2300 mg/kg of body weight/day
The ATSDR studies to date conclude that Al is 6 times more toxic than Sr. ATSDR Studies to date conclude that Aluminum is 6 times more toxic than Strontium. http://www.atsdr.cdc.gov/toxprofiles/tp22.html
Ferrite type magnets before 1987 were made using Barium. Ferrite magnets earned the reputation among dairy veterinarians for being toxic to cows. Gradually some factories have replaced Barium with Strontium in ferrite magnets. However, there is still a fear associated with radio-active type Strontium 89 and 90. This fear has kept veterinarians from using cow magnets made with stable Strontium 84, 86, 87 and 88.
According to the present invention, a mineral supplement cow magnet comprises a solid piece of SrFeO with a dosage of only non-toxic and healthy minerals. The magnet in accordance with the present invention is made of or coated with healthy minerals for cows. The magnet in accordance with the present invention may have pole patterns configured to localize metal fragments at particular locations on its surface, so as to minimize the risk of injuring the cow's stomach. The nails will be pulled to a position parallel to the length of the magnet and centered along the length. The invention is dimensioned and weighted so as to not pass on to a cow's intestines. The magnet material having stronger magnetic properties than current cow magnets.
According the National Research Council (NRC) Aluminum is toxic at levels of 1000 mg/kg of body weight. Strontium is not toxic until 2000 mg/kg. Aluminum is twice as toxic as Strontium, in this study:

New data supports SrFe cow magnets. My previous patent U.S. Pat. No. 5,128,644, July 1992, Nellessen, a SrFe magnet assembly type cow magnet, has been tested for over 10 years in cows. No muscular growth losses, no bone loss, no nervous system disorders, no metabolism disorders, or any of the disorders associated with Aluminum, were found. The past fears of Barium being used in ferrite magnets can be dispelled.
While many devices have attempted to adequately account for these factors, none have successfully done so. The need exists, therefore, for a durable yet non-toxic cow magnet possessing a relatively strong magnetic field that may be easily introduced into the stomach but that cannot pass into a cow's intestines, which safely collects metal fragments while being inexpensive to construct.

A preferred embodiment of the cow magnet of the present invention is illustrated in
Additional Embodiments are shown in
There are various possible pill shapes. There are various surface treatments of healthy minerals. While the invention has been described in five embodiments, it is to be understood that the words which have been used are words of description rather than limitation, and that changes may be made within the purview of the appended claims without departing from the true scope and spirit of the invention in its broader aspects.
The nutritional value of Sr is discovered to help bone growth and strength. The polarity pattern is discovered for a SrFe type magnet so that a nail will be held along parallel to the length of the magnet and pulled towards the center of the length. This pole pattern has been discovered to turn a nail parallel to the length of the magnet if the nail is placed on the magnet perpendicular to the length. Furthermore, this pole pattern also prevents a nail from being held along the length of the magnet with the sharp nail tip sticking out the end of the magnet. The magnetic properties of this material make it difficult to demagnetize with time or heat or other magnetic fields. The invention has a shape that may be easily introduced into the first stomach, but that cannot pass into a cow's lower stomachs, which safely collects metal fragments, while being inexpensive to construct.
The mineral supplement cow magnet is pushed down the cow's throat. It stays in the first stomach due to its weight and size. It slowly leeches Sr and Fe minerals of the magnet. The Sr is used with Ca to increase bone osteoblasts. Which increase bone growth. The Sr has also been found to stop absorption of the bone by the body know as osteoporosis. The magnet collects metals to keep them from going down into the cow's more delicate second, third and forth stomach. The magnet holds the metal along the magnets length so that sharp edges of metal are covered by round edges of magnet.
Accordingly the reader will see that the mineral supplement cow magnet invention of this patent is most likely to prevent sickness and death in cows. The need exists, therefore, for a healthy mineral supplement cow magnet. One that is non-toxic, without Aluminum, possessing a relatively strong magnetic field. The polarity pattern is discovered for a SrFe type magnet so that a nail will be held along parallel to the length of the magnet and at the maximum strength. This pole pattern has been discovered to turn a nail parallel to the length of the magnet if the nail is placed on the magnet perpendicular to the length. Furthermore, this pole pattern also prevents a nail from being held along the length of the magnet with the sharp nail tip sticking out the end of the magnet.
The magnetic properties of this material make it difficult to demagnetize with time or heat or other magnetic fields. The invention has a shape that may be easily introduced into the first stomach, but that cannot pass into a cow's lower stomachs, which safely collects metal fragments, while being inexpensive to construct. Furthermore, the cow magnet has the additional advantages in that
Although the paragraphs above contain many specifications, these should not be construed as limitating the scope of the invention. For example the pill shape could be achieved in a dog bone shape, ring shape, pretzel shape, or any shape with rounded corners. Thus the scope of the invention should be determined by the claims and their legal equivalents.
