Abstract: The device is a combination of an inexpensive, disposable utility razor blade and a human breath powered audible noise making devide, or whistle. The disposable blade is held in place with a pin or other means and can easily be replaced with another blade. The whistle is integrated into the design to also act as the handle for the utility razor. The whistle designed is a tri-tone whistle that generates three distinct audible beat frequencies in order to create a distinct sound. The three primary frequencies are approximately 3 KHz but with slight differences in frequencies that generate a 30 Hz beat frequency between the two lowest frequencies and a 45 Hz beat frequency between the two highest frequencies. The difference between these beat frequencies generates a secondary beat frequency of 15 HZ.

Abstract: An animal feed that comprises a feedstuff and a coating, where the coating increases the amount of the feedstuff that passes through the rumen without being degraded by the rumen microflora, thereby delivering a larger portion of that feedstuff's associated preformed protein, and the essential amino acids comprising that protein, to the lower gastrointestinal tract. A process for making an animal feed, where the animal feed has enhanced rumen bypass nature of feed ingredients and their associated nutrients, particularly preformed protein and the amino acids that comprise the protein. Methods of increasing the rumen bypass of phosphatidylcholine, methods of increasing the vitamin E value of a feedstuff, methods for increasing rumen escape of the protein and amino acids in a ruminant animal.
