Description

[Detailed explanation of the idea]

(Field of Industrial Application) The present invention relates to a device that stimulates the reproductive organs of livestock such as beef cows in order to promote their growth. (Prior Art) It has been proposed to administer various chemicals and hormones to promote the growth of beef cows. (Problem that the invention aims to solve) However, when administering such chemicals and hormones, if their use is not strictly controlled within a certain period of time before slaughter, the chemicals and hormones will remain in the meat. In addition, if the embedded capsules are not removed properly at the slaughterhouse, the beef will be contaminated with chemicals and hormones, causing abnormal growth in infants and children who eat the beef. . To prevent this transfer to the human body, it is necessary to allow a certain waiting period before slaughter, and the burden of feeding management costs during this period becomes a problem. Therefore, the purpose of the present invention is to eliminate the risk of contaminating the meat with substances harmful to the human body, to be able to attach it to livestock with an extremely simple operation, and to allow livestock for meat to be kept on standby for a certain period of time. To provide a device for promoting the growth of livestock that can be shipped immediately without waiting. (Means for Solving the Problems) The following description will be made using the reference numerals in the attached drawings.
a guide tube 1 that is inserted into and removed from the vagina 6 of a person; an insert body 2 that is housed in the distal end of the guide tube 1 with a plurality of elastic pressers 3 in a folded state; and an insert body 2 that is inserted into the guide tube 1;
It consists of a pushing rod 4 that pushes out the insert 2 from the guide cylinder 1 at the front part of the vagina 6 that is continuous with the cervix, and presses and stimulates the cervix and the vaginal wall with the expanded elastic presser 3. It is something to do. (Function) Before using this device, consult a veterinarian to check whether the reproductive organs of the target livestock, such as beef cows 5, are healthy, and confirm that there are no malformations or diseases such as infectious diseases. After inserting the folded insert 2 into the tip of the guide tube 1, immerse the device in warm water containing a disinfectant to disinfect and clean the entire guide tube 1, insert 2, and push rod 4. become After applying a lubricating oil that is harmless to the living body to the tips of the guide tube 1 and the insert 2, the guide tube 1 is inserted from the tip into the vagina 6 of the cow 5, so that the tip comes into contact with the cervix of the uterus. gradually move it deeper. After contacting the cervix, the guide tube 1 is pulled out from inside the vagina 6. At this time, in order to prevent the insert 2 from escaping together with the livestock tube 1, the push rod 4 is used to pull the guide tube 1 out of the vagina 6. Hold down the rear end of 2. When the guide tube 1 is pulled out from the vagina 6 in this way, the insert 2 pushed out into the vagina 6 by the push rod 4 is released from the restraint by the inner circumferential surface of the guide tube 1, so The elastic depressor 3 of the insert 2 presses against the cervix and vaginal wall in an attempt to elastically return to the expanded state. This pressure stimulation of the uterine cervix and vaginal wall calms down the cow during the breeding season and eliminates mating behavior, resulting in a marked increase in feed consumption and increased body weight gain. (Embodiment) In the illustrated embodiment, the guide tube 1 is a cylindrical body made of plastic, and as shown in FIG. 2, an inward flange 7 is provided at the rear end opening. Extrusion rod 4
As shown in FIG.
A protrusion 8 is provided which engages with the guide tube 1, thereby preventing the push rod 4 from slipping out of the guide tube 1. A plurality of scale protrusions 9 are formed on the extrusion rod 4 at equal intervals along its length. A knob disc 10 is fixed to the rear end of the push rod 4. The insert 2 is made of plastic, and a ring body 12 is connected to the distal end of the round bar-shaped main body via three support legs 11. 12 comes into contact with the cervix. The elastic pressers 3 are provided radially protruding from the rear end of the round rod-shaped main body in four stages, and six elastic pressers 3 are arranged in each stage at equal angular intervals. Each elastic presser 3 is bent backward at two bending points 3a and 3b, as shown in FIGS. It is provided. Note that the shapes and structures of the insert 2 and the elastic presser 3 are not limited to those shown in the drawings, and they can be folded before insertion and elastically expanded after insertion to allow the cervix to touch the inner wall of the vagina. Any material that can be pressed is sufficient. (Experimental example) The growth promotion device of the above example was attached to 35 beef cows in the test area, and the same was applied to the test and control areas without attaching this device to 30 beef cows of the same species in the control area. When the rats were fed with the formulated feed and reared, the results shown in Table 1 were obtained. The device was inserted into the heifers in the study area at the start of the study and remained in place for the entire study period.

[Table] As is clear from this table, the test plot exceeds the control plot in terms of average weight gain per day, and in the carcass grade distribution, there are some that belong to the special category that are not found in the control plot, and some that belong to the top and some that belong to the This device was found to be effective in promoting growth, increasing weight gain, and improving meat quality in beef cows. (Effect of the invention) As described above, in the growth promoting device of the present invention, the plurality of elastic pressers 3 are folded and the insert body 2 is housed in the tip of the guide tube 1, and the guide tube 1 is The insert body 2 is inserted into the vagina of a domestic animal such as a cow, and is pushed out from the guide tube 1 by a push rod 4 at the anterior part of the vagina that is continuous with the cervix. By physically stimulating the uterine cervix and vaginal wall, this method calms the livestock, increases the amount of feed it eats, and increases body weight gain. Since there is no risk of migration into the meat, it is easy to manage the safety of the meat. In addition, there is no need for a certain waiting period before slaughtering, as is the case when administering chemicals or Holemon.
Since the livestock can be immediately shipped and slaughtered when it reaches the required weight, feed intake during the waiting period can be saved, and livestock feeding management costs can be reduced. Furthermore, the insert 2 that provides pressure stimulation for promoting growth can be easily attached to a domestic animal by means of a guide tube 1 and a push rod 4 that are inserted into the vagina of the domestic animal. 2 remains in the vagina until the time of slaughter, and is not removed from the vagina unless particularly necessary, so it is extremely simple to use and handle.
