DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to an internal identification apparatus for animals, and particularly, to an internal identification apparatus to be swallowed by a ruminant and that stays in the first or second stomach of the ruminant. The apparatus may be embedded in a subcutaneous part of an animal. Data related to the animal is read out of the apparatus by an external apparatus, to identify the animal.
BACKGROUND ART
Various identification apparatuses and methods for animals have been proposed for the livestock industry, to manage the shipment, ownership, and individual conditions of livestock such as cattle, hogs, and sheep. Most generally used identification devices are tags printed with numbers and marks. The tags are fixed to the ears, legs, ankles, or tails of animals. The tags are convenient for limited use for farms because they are easy to handle.
The tags, however, are not suitable to nationally or regionally control and breed livestock because they must bear large-digit numbers and because they are unreliable when they are replaced with others. Instead of the tags, black and white patterns for Holsteins or nose patterns for Japanese black cattle are frequently used.
Identifying individual livestock was originally to clarify their ownership. The identification is required nowadays to improve and evaluate individual livestock. Livestock must be individually identified for registration and deals. Stock raisers must identify individual livestock to breed and manage them.
An identification apparatus for animals is required to correctly identify each livestock and provide unchanging, unique, objective, easy-to-judge data. The apparatus must be easily attached to livestock and must be safe for livestock and their products.
A rapid development in electronic technology has realized a very small electronic apparatus for an identification system for livestock. The system transfers data in a noncontact manner with magnetism, radio waves, or light. The system is interlinked with a computer to utilize the data for various purposes.
The system includes a transponder, an antenna, and a reader. The reader is connected to a host computer, which uses data read out of the transponder for various purposes. For example, for a stock raiser, the data are used for automatically feeding livestock and recording the weight of individual livestock. For a livestock market, the data are used for securing livestock prices and evaluating the quality of meat of slaughtered livestock.
The transponder employs a small capsule that contains an integrated circuit and an antenna. The transponder is activated in response to electromagnetic waves from the reader and transmits stored ID codes on radio waves. The reader receives the radio waves, decodes the ID codes, and records the decoded data.
The transponder was originally about 10.times.5.times.3 cm in size and was fitted to the neck of an animal. Presently, it is a small hermetically-sealed glass capsule of about 1 to 3.6 cm in length and 1.5 to 4 mm in diameter. The capsule is embedded in a part of an animal, such as an ear or a tail. The animal walks in front of the reader, and the reader reads ID codes stored in the transponder.
The conventional identification system employing the transponder to be embedded in an animal has the following problems in practical use: that it is unsanitary. It takes time and labor to catch an animal and embed the capsule therein. glass, may break in the animal. time to locate and collect the transponder from a slaughtered animal. end up in food. an ear, it may cause a read error because the distance between the transponder and the reader fluctuates. taken out of the animal and may be illegally embedded in another one.
A first object of the present invention is to provide an internal identification apparatus for animals, in particular, ruminants such as cattle, sheep, goats, and deer. The apparatus is inserted into the first or second stomach of a ruminant and stays there. The apparatus easily, safely, and surely settles in the fir
