Description
5~7~
~1 _ The invention relates to a device for determining ovulation ;n domestic animal~ such as sows, cows and mares.
~ hen, in the case of domestic animals such as sows, cows and mares, ovulation is to be determined in order to service them at the correct moment, it is customary to take the animal's ~ody temperature daily by inserting a thermometer into the animal's anus or vagina~ Servicing is carried out when ovulation is indicated by :the detection of increased body temperature, as compared with the normal temperature.
In these domestic animals, the increase în temperature upon ovulation is generally the same, whereas the animals' normal temperatures are different and may vary within certain limits.
Determ;ning ovulation in these animals ;s thus a complex matter, since not only must the temperature of the animal to be serviced be taken daily, but the animal's normal body temperature must be known in order to determine the tempera~
ture differential, The complexity of this method of determin~

ing ovulation is further inc~ea$ed when several animals are awaiting seryiciny2 ~ erman ~S 21 15 162 discloses an axrangement for monitoring the onset of delivery in domestic animals by means oE an electr~c signal generator. According to this invention a capsule is insertable into the animal~s genital canal and is connected to a transmitter adapted to be switched on and off hy a temperature sensor. A receiver is tuned to the trans-mitting frequency of the transmitter. If the capsule ls placed in the animal's genital canal long before the start of delivery, the capsule's transmitter and signal generator remain switc~ed off as a result of the relatively high tem-perature within the genital canal. As soon as delivery begins, the capsule is expelled from the genital canal and the temperature of the capsule drops, thus switching on the transmitter. It is also stated in this patent that the capsule transmitter may be designed and adjusted in such a manner that it is activated only when a predetermined high temperature is reached. It would therefore be possible to use this device to indicate a fever or ovulation in an animal.
The disadvantage oE the invention disclosed in German AS 21 15 162 is that only a specific temperature can be analyzed by the measuring system contained in the capsule.
Temperature differentials cannot ~e determined by this device, and this is indispensable for simple and reliable determina-tion of ovulation in anîmals. The device is thus unsuitable for determining ovulation without an additional thermometer for determinîng the animal's normal ~ody temperature. Further-more, because of the configuration of the capsule which is to be introduced into the animal and which consists of a plurality of parts, the device is dif~icult to handle. Another dis-advantage is that after ovulation has begun, the capsule must be remo~ed ~rom the animal. ~efore it can be used for .
~3--another animal~ it mu~t be cleaned and, if necessary, taken apart in order to alter t~e tempexature at which the tem~
perature switch is actuated.
It is a purpose of the present invention to provide a device ~or simple and reliable determination of ovulation in domestic animals such as sows, cows and mares.
The present invention provides a temperature sensor adapted to be inserted into the animal's vagina and which actuates a signal generator whenever a specific increase in temperature is sensed~
In contrast to the prior method of measuring the temperature with a thermometer inserted into the animal's anus or vagina, temperature sensing according to the present invention offers the advantage that the temperature sensor can be left in the animal during the period in which ovulation is expected. Thus, possible errors arising from the daily reintroduction of a thermometer into the animal's anus or vagina are eliminated.
According to one particular embodiment of the invention, temperature differentials can be determined by the sensor, and this is the only accurate way of determining ovulation. The procedure is to insert the temperature sensor into the vagina when the animal's body temperature is still normal, and to use the normal body temperature thus determined as a basic value. The device will then produce a reference value which, in relation to the basic value, corresponds to the increase in body temperature associated with ovulation~
It is advantage.ous to determine temperature differentials by means of a temperature dependent resistor arranged in the temperature sensor.
According to one em~odiment of the invention, the measuring leads running out of the animal are in the form of a complete lead In order to ~acilitate insertion of the lead into the animalls ~agina, the part inserted should be less flexible. This ensures, on the one hand, that the temperature sensor may be easily introduced into and removed from the animal and, on the other hand, that the part of the lead which remains ou-tside the animal is flexible enough not to inconvenience the animal, particularly in its tail area.
If the device according to the invention is used with an animal which naturally behaves quietly in her stall, the signal generator may be arranged at a display location in the stall, being connected to the transmitter through a lead. If, on the other hand, the device is used ~ith an animal which is restless in the stall, or is kept in the open, the signal generator and transmitter must be attached to the ani~al, preferably to the back, belly or neck thereof.
T f the temperature sensor passes to the signal generator information to the effect that a temperature differential has been detected, i~e. that ovulation has begun, this signal is passed to the transmitter. Provision is made for the signal generator and if possible, the transmitter, to be close to the animal. If necessary, the transmitter may also be preceded by a unit comprising a plurality of connections for devices for determining ovulation. The person seeking this information is equipped with the corresponding receiver and can thus establish the daily pattern independently.
In the case of domestic animals such as sows~ cows and mares, the onset of birth îs also associated with an increase in the animal's bod~ temperature, As in the case o~ ovulation, the temperatures of the said animals differ at the onset of bîrth, but the difference between the animal ~5 normal temperature and the temperature associated 7~
~5~
with the onset of birth remains about the same~ The deyice according to the invention may therefore be used not only to determine ovulation hut also to determine the onset of birth.
It is important in the case of the said domestic animals to know the time of onset of birth in order that help may be provided during birth in the event of possible complications.
A preEerred embodiment of the invention is described hereafter with reEerence to the drawing.
The drawing is a side elevation of a stall containing a sow with the device according to the invention inserted into the vagina.
In the drawing, the stall 1 comprises a front part 2 and a rear wall 3, the width of the stall 1 being such that the sow 4 cannot turn around therein.
Part of a flexible line 8, the end of which accom-modates a temperature sensor 9, is introduced, through inlet 6 to the vagina 7 located below the anus 5. In order to eliminate the possibility of the lead 8 slipping back out of the va~ina 7, the part of the lead within the vagina is fitted with a rubber ball 10. The lead 8 is encased in rubber or other suitable material which is not attacked by animal excrement or urine, The other end of the lead 8 is fitted with a plug 11 secured laterally to the animal with a strap 12. Fitted to lateral wall 13 of the stall is a signal generator 14 connected to the lead 8 by a flex-ible lead 15, the end of which remote from the signal generator 14, is fitted with a socket 16 for connection to the plug 11, Another lead 17 runs from the signal generator 14 to a socket panel 18 to which a plurality of signal generators may be connected by additional leads 17.
A further lead 19 runs from the socket panel 18 to a trans-mitter 20. Sections of leads 15 and 17 which run within the stall may be secured to the relevant lateral wall with .~
'7~
~6 attachment means 21~
If the sow is due to o~ulate~ the lead 8 is inserted into the vagina 7 while the sow~s ~ody temperature is still normal. In order to facili.tate intro~uction of the lead into the sow's vagina f the part o~ the lead so introduced should be less ~lexible than the remainder of the lead.
As soon as the lead ~ with the temperature sensor 9 has been introduced into the sowls vagina 7, a correspond-ing circuit in the signal generato~ 14 can be balanced to attribute to this normal temperature a ~asic value, for example, zero. The basic value may be determined by cutting in a plurality of circuits having variable resistors until one resistor in a circuit is matched exactl~ with a specific NTC resistor representing a specific temperature. The cutting in as such is effected b~ means of a rotary switch 23. As soon as two resistors match, a lamp 22 fitted to the signal generator 14 comes on. In this case there is no need to know the normal temperature of the animal in order to determine the basic value.
The higher temperature, as compared with the normal temperature~ at which ovulation takes place is an empirical value. In accordance with this temperature differential, the switch 23 is rotated over a scale 24 representing units of temperature differentlal, in the direction of increasing values. The result of this is that lamp 22 on the signal generator 14 goes out. If ovulation has taken place in the animal and the set temperature differential has been exceeded, the lamp 22 on the signal generator 14 comes on again and the signal is passed, through the lead 17, the socket panel 1~
