Description

Remote cow oestrus monitor

Remote cow oestrus monitor of the present invention (hereinafter to be referred as " identification apparatus ") is that a cover is used to identify that cow in estrus and record cow are by the device of mounting number of times.This device also can be used for domestic animals such as horse, donkey, deer, sheep and other has when oestrusing by the jenny of mounting behavior.

The evaluation of oestrusing is the most important link in the cow artificial insemination.Identify that in time, exactly thereby cow in estrus carries out artificial insemination, can improve conception rate effectively, shorten farrowing internal, consequently reduced production cost, increase investment returns.This is particularly important for the test-tube dairy of extensive employing.Along with improving constantly of people's living standard, increasing local ox and buffalo carry out crossbreeding and improvement so that more breast, meat product to be provided to society by technology of artificial insemination.These oxen are oestrused in time, exactly identify and also to seem important day by day.Since estrus of cow have period by bull and other cow trail, the behavior of mounting, and as seen the cow in estrus external genital has mucus to flow out, traditional authentication method of oestrusing is that poultry is main early morning with before and after milking at dusk, the time intercropping of spending half an hour to the 1 hour observation of oestrusing, when observing above-mentioned disease, promptly be accredited as and oestrus.Yet, this oestrus to observe not only all to spend nearly 2 hour time every day, and because nearly 60% estrus of cow occurs in 17:00～5:00, and the estrus duration of quite most cow is shorter than 12 hours, therefore, traditional method just can not be very high to the recall rate of cow in estrus.Along with the expansion of cows and the rising of labour's price, the appraisal cost of conventional method will improve from now on, and will identify accurately and timely that cow in estrus is just difficult more.Measure and " vagina mucosa resistance variations remote control determination method " or the like method though also gradually adopted at present such as the body temperature remote control of " rectal palpation method ", " marking animals examination feelings method ", " vaginal mucus method of control ", " hormone determination diagnosis ", " body temperature variation determination method ", " activity determination method " and latest developments, all owing to various reasons, still not having at present a kind of method and instrument can replace traditional method fully and carry out estrus of cow and identify that these methods and instrument can only help out.

Can be when the present invention is based on estrus of cow by other ox mounting, and the mounting behavior produces certain pressure to cow root of the tail and buttocks, after special switch is placed at these positions, as long as there is the mounting behavior to take place, just can utilize this pressure to open or powered-down, thereby start or stop the effect of radio signal generator; And receive, write down, analyze these signals by radio signal receiver, just can identify and oestrus.Owing to generally have only the cow in estrus just can be by its ox mounting, and in case there is the mounting behavior can the enabling signal switch, its signal can be received by the receiver, record, so this identification apparatus has higher accuracy rate and recall rate to the evaluation of cow in estrus.Analyze from Financial cost, under the situation that industrialness is produced, each signal generator adds that battery will can not surpass 15 yuan of RMB (referring to present worth, down together); Every fixed band adds that switch is no more than 2 yuan; Receiver (referring to not band signal analyzer and recorder) will be no more than 500 yuan; The receiver of band analyzer and recorder will be no more than 2,000 yuan.The expense of estimating every evaluation one hair feelings ox will can be above 10 yuan.And now the breeding expenses of every ox every day about 4 yuan.Therefore, identification apparatus of the present invention will have higher utility in China, have sizable market in developed country.

According to accompanying drawing identification apparatus of the present invention is set forth below.

Fig. 1 is the basic principle figure of this device.

Fig. 2 is the pie graph after receiver is equipped with signal analyzer (5) and recorder (6).

Fig. 3 is the basic comprising figure of signal generation part (1).

Basic comprising figure when Fig. 4 is signal generation part (1) employing electronic switch.

Fig. 5 is the diagram when being positioned over behind the specific pocket of fixed band (14) and signal generation part (1).

Fig. 6 is the vertical view of fixed band (14) when signal generator (1) is fixed in oxtail root and buttocks.

Fig. 7 is that fixed band (14) is with the fixing back of signal generation part (1) ox body cross-sectional view.

Identification apparatus of the present invention is made up of the part of two separation, and promptly partly (1) (hereinafter to be referred as signal generation part) and radio signal receiver (3) (hereinafter to be referred as receiver) take place radio signal.In addition, also have one to play the fixed band (14) that part (1) effect takes place fixed signal.

Signal generation part (1) is mainly by a radio signal generator (9) (hereinafter to be referred as signal generator), and a pressure switch (8) and battery (7) are formed (Fig. 3).Switch (8) if machinery, the function that this can have been realized receiving mounting information and sent radio signal (hereinafter to be referred as signal) by three signal generation parts (1) of forming.If adopt electronic switch (8), need to increase a relay (11).Use a counter (12) to write down the effective time that mounting number of times and a timer (13) limit each counting in addition.No matter switch (8) be machinery or electronics, all adjust to and need reach predetermined pressurized number of times and just switch on or off power supply.Therefore some are out of heat but once in a while by the cow of mounting just to get rid of mistaken diagnosis.The signal (2) of one group of signal generator (9) emission can be different frequency with wave band or same frequency and different password.Signal generator (9) should have the antenna (10) of certain-length.Switch (8) with except outside the Pass signal generation part (19) peg graft by lead.

Signal generator (3) then needs the professional in the situation of oestrusing of monitoring cows sooner or later when not being equipped with signal analyzer (5) and recorder (6).The type of the antenna (4) of signal receiver (3), the actual range that setting height(from bottom) can be monitored as required decides.

Fixed band (14) should be made (as medical proof fabric) by quality softness, the adhesive material of one side.It vertically has signal generation part (a 19) pocket (18) except that switch (8) with having on (15) on a switch (8) pocket (16) and the transverse belt (20).Vertically band (15) prolongs root of the tail and pastes to the buttocks vertebra, just in time switch (8) is fixed on the root of the tail or the vertebra back side, when cow can experience pressure during by mounting.Transverse belt (20) is pasted around root of the tail, makes the signal generation part (19) except that switch (8) be in the root of the tail side, not can because of cow by the mounting fail in compression.

Identification apparatus of the present invention identifies that cow in estrus is achieved in that

The power supply of signal generator (9) switches on or off circuit by pressure switch (8) and controls.This switch (8) is defined to be wanted just can switch on or off power supply behind the certain number of times of pressurized, cow is every by mounting once, switch (8) pressurized once, the pressurized number of times of qualification is reduced once, when pressurized reaches the qualification number of times, switch (8) switches on or off power supply, and signal generator begins or stop to send signal (2).If to receive that signal serves as to identify to oestrus, then pressurized reaches circuit connection when limiting number of times, signal generator (10) sends signal (2), otherwise then stops to send signal (2).Different ox individualities carry the signal generator (9) that can send unlike signal (2), these signals (2) are received the personnel that can be operated after device (3) is received or analyzer (5) difference is come, thereby cow in estrus can be identified from cows, once oestrus and identify that promptly announcement is finished.

Oestrus identify finish after, switch (8) with except outside the Pass signal generation part (19) break away from, the latter reuses, just replacement battery (7) when electric energy is not enough.Fixed band (14) and switch (8) can be abandoned it.
