"SYSTEM AND PROCESS FOR THE AUTOMATIC IDENTIFICATION OF
ANIMALS"
TECHNICAL FIELD
The present invention relates to a system and a process for the automatic identification and location of stock animals.
Data collected by said system by means of said process can be advantageously utilized for instance to early locate subjects at risk or affected by several pathologic conditions. In particular, the present invention relates to a system and a process for monitoring animals through their automatic identification and location in a fixed area or position, in order for instance to early identify those subjects that might develop ketosis and/or hypoglycemia, by exploiting the correlation between the data surveyed, both the number of times and the duration of stays of the animals at the trough. BACKGROUND ART
From the endocrine-metabolic point of view, the more stressing period for milk cattle is "peri-partum" when even a small lack in nutrients can affect the subsequent lactation. By the term "peri-partum" there is intended to indicate the period of time from the end of pregnancy and the start of lactation.
The attention of the operators involved in the production process aims at preventing drawbacks of any kind, such as environment or alimentary stresses and illnesses, and particularly at maximizing in the peri-partum period nutrient intake (for instance, dry substances) to reduce puerperal pathologic conditions (e.i., ketosis, steatosis, abomasum displacement, hypofertility, etc.), and to satisfy the alimentary requirements necessary to support partum and the subsequent sudden increase in milk production.
In the same way, reduction in feeding of the animal (reduced use of trough) might be a sign of other pathologic conditions (already existing even though in the start stage), such as placenta retention, metritis, acidosis, locomotion apparatus affections, etc.). Metabolic variations and the stress that characterize peri-partum result in a reduction of aliment intake that causes in the animal an abrupt drop in blood glucose and an intense mobilization of deposit lipids (released as NEFA (non-esteric fatty acid), and oxidized to ketonic bodies, due to the lack of oxalacetic acid) which, were it not timely limited, would lead to a clinical ketosis condition.
Nervous symptoms ensuing from the presence of ketonaemia and hypoglycemia also lead to dysorexia that causes energy deficit to become even worse. The mean incidence of ketosis in milk cattle amount to 7% per year, which means a high cost for breeders, followed by the endangering of production and reproduction performances, the elimination of subjects and the increase in labor and veterinarian expenses. Usually, the efficiency in identifying health conditions and assisting animals depends on the capacity and the time available to farm operators. In practice, animals are not timely assisted, and are subjected to specific treatments only when the pathological clinical symptoms are clearly evident, with the consequence that the intervention is untimely and therefore poor. Early identification of cattle with energy deficit problems and a timely intervention allow to prevent the endangering of health conditions and productive and reproductive performances. There emerges therefore the necessity of an early survey system of health problems which should be reliable, of easy application and errorless in the evaluation of a possible intervention on animals.
Such an early survey requires the automatic identification of animals through their monitoring in a fixed area or position (for instance, at the trough).
Transponder systems are known for the automatic identification of animals. Such systems are based on the decoding of electromagnetic waves sent by a sender fixed on the animal. Such systems are comprised of:
- an antenna acting as a transceiver that continuously emits electromagnetic waves; and - a transponder fixed on the animal, which is activated by the electromagnetic waves and sends said antenna a signal which a code corresponds to.
Such systems have the drawback of not allowing the simultaneous transmission of data sent by several transponders towards one only antenna. This is why antennae are usually located in correspondence of an obligatory way for animals (e.g., doors, corridors, etc.) where animals are obliged to pass through one by one (in a row). Alternatively, antennae are located in the inside of each individual posting (for instance, feeding box or milking post). Besides, these systems are not easily applicable when the simultaneous identification of many animals is required (e.g., to monitor the presence of animals at the trough). In this case, in fact, the known systems require the utilization of an antenna for each posting, with ensuing high installation costs and low reliability due both to the complexity of wiring systems and the high number of connections.
DISCLOSURE OF THE INVENTION
The main object of the present invention is to provide a system as well as a process for the automatic identification of animals in
correspondence of α given area or position, which should be simple both for its utilization and the possible maintenance operations, which should be economical, highly reliable and such as to allow a simultaneous communication between an antenna and several transponders.
It has been found that in milk cattle a high correlation exists between energy deficit (ketosis) and aliment intake (e.g., dry substances). As a consequence, the knowledge of the individual aliment consumption throughout the day allows the operator to early identify the subjects needing an intervention.
Therefore, object of the present invention is a system for the automatic identification of animals in a fixed area or position, comprising the following components:
- one or more satellites comprising electronic transceivers, fixed each on an animal to be monitored;
- an ignition device able to emit signals to activate said satellite(s);
- one or more antennae having the function of collecting device for data sent by the satellite(s); and
- a PC control and processing device that stores and processes data sent by said one or more antennae.
The satellite comprises an electronic circuit fed by batteries, closed in a watertight box and fastened to the animal, for instance at the neck, the foot, etc. The satellite activates when the animal approaches the ignition device, for instance at the trough. The ignition of the satellite involves the transmission of an identification code and/or the storing of the ignition time period. The satellites may be installed on all the animals of the farm or only a part thereof.
The ignition device is placed near the location to be monitored and can activate the satellite fixed on the animals from a distance that
ensures α correct association between the animal and the monitored position.
The ignition device is placed close to the location to be monitored, preferably within the trough location. The ignition device emits a radiofrequency magnetic . or electromagnetic field which is perceived by the satellites only when the animals approach said device.
The ignition device may comprise one or more generators of electromagnetic waves or magnetic field generators suitably placed within the location to be monitored. In both cases, the cost of the ignition device is particularly low and its installation extremely simple.
The same ignition system can simultaneously ignite several satellites that are present within the monitored area.
As said above, the data collection system comprises one or more antennae located in the inside of the place where monitoring takes place, for instance within the cowshed, and collects the data sent by the satellites and transmits them to the PC control and processing device. One or more antennae may be located in the area to be monitored, according to the size of said area. If the satellite is provided with an active storage, the antenna may be located in correspondence of animals' obligatory way. Before receiving the data collected in the satellite storage, the antenna emits a signal that activates their transmission from the satellite.
The system according to this invention should be so adjusted as to cause the ignition each time the animal is in the monitoring position, for instance in feeding position at the trough.
According to this invention it is therefore possible to use one only ignition device to ignite one or more satellites, located each on an animal to be monitored, and also it is possible to utilize one only survey
system (antenna) for the collection of data sent by several satellites, located each on an animal to be monitored.
The single elements of the system according to the present invention are either known per se or may be modified according to the way specified herein, -for instance, satellites may be provided with a storage.
Another object of this invention is to provide a process for the automatic identification of animals through their monitoring in a fixed area or position, characterized in that one or more satellites performing the function of transceivers, fixed each on an animal to be monitored, are activated by the signals emitted by an ignition device whenever the animal is in the fixed area or position, and after the activation, during the ignition, said satellites send the identification data to at least an antenna, that performs the function of a data collecting system and that collects and transmits them to a PC control and processing device for their storage and processing. The identification and possibly subsequent data may be transmitted to one or more collection devices, i.e. to one or more antennae, in the following ways: - the animal identification code is directly transmitted to one or more antennae located in the monitored location; preferably, said transmission takes place at regular and close intervals (e.g. 20 seconds), allowing the PC control and processing device to monitor uninterruptedly the animal during its presence in the fixed location or position, for instance, in the trough;
- the animal identification code is transmitted together with a signal that indicates the start or the period of staying in the fixed area or position (for instance, feeding position) and afterward, when the animal is no longer in the fixed area or position to be monitored
(e.g., when the animal is going away from the trough), the same identification code is transmitted for a second time together with a signal that indicates the end of the monitored position (for instance, and of the feeding time). These data may be transmitted 5. towards one or more- antennae located in the monitored area, preferably within the shed. Afterwards, the PC control device calculates the difference between the times surveyed by the two aforesaid signal transmissions. The difference between these times corresponds to the staying time within the fixed area or position to 0 be monitored (for instance, the time spent at the trough);
- the staying time of the animal in the fixed area or position (for instance at the trough) is stored in the satellite circuit fixed on the animal. This type of information storing may take place according to two different ways: 5 a) complete information: the satellite storage can exactly store
(hour, minutes, seconds) the start and the end of the time the animal spends in the fixed area or the position to be monitored (e.g. feeding start and end); b) limited information: counting of intervals; the storage of the 0 satellite is comprised of a counter which is increased at regular intervals (e.g., every 20 seconds) during the period of ignition of the satellite (e.g., during the staying of the animal at the trough). This type of storage allows to simplify and reduce the satellite costs.
Data are transmitted at regular intervals to the antenna located in 5 the location to be monitored (e.g. within the shed). Alternatively, storage reading may take place on request (through an impulse) by an antenna located in correspondence of an obligatory way of animals (e.g. at the entrance of a milking post).
Data received by the antenna(ae) are sent to a farm PC, that
provides to their storing and processing.
A further object of this invention is the use of data that may be correlated to the number of times and the duration of stays at the trough, to early identify subjects at risk or affected by the different pathologic conditions connected to aliment taking.
According to a preferred realization of this invention, the animal provided with a satellite is monitored at the trough from the viewpoint of the number of times of food taking, and the duration of food taking (feeding). The satellite fixed on the animal neck to be monitored, activates automatically when the animal approaches the trough, i.e. when it takes a feeding position.
The activation of the satellite is by means of electromagnetic waves emitted by an ignition device, and as a response to such activation signals, the satellite transmits its identification code. Such transmission takes place at regular intervals of about 20 seconds, to allow a continuous monitoring up to the moment when the animal has no longer the feeding position, i.e. it goes away from the trough. These identification data are transmitted to the antenna located in the inside of the shed which collects and then send them to a PC control and processing device wherein they are stored and processed.
Based on PC processed data (frequency of aliment taking and feeding duration) farm operators can objectively evaluate the necessity of a possible intervention on animals subject to ketosis and/or hypoglycemia risk. The system and the process according to this invention allow the identification and monitoring of several animals within a fixed area or position by reading and decoding the signals (data) sent simultaneously by several satellites to one only antenna in a simple, economical and reliable manner.
