Description

[Detailed Description of the Invention] "Industrial application field" The present invention is a fertilized egg that can be transferred in a sanitary and denatured state in which fertilized eggs of cattle, pigs, sheep, etc. can be immediately transplanted. Regarding transportation equipment.

“Prior Art” Conventionally, a known fertilized egg transplanter (hereinafter referred to as “transplanter”) 1 shown in FIG. 8 has been used to inject fertilized eggs into livestock such as cows.

The transplanter 1 is composed of a transplanter main body 2 and an outer tube 3 attached to the transplanter main body 2, and presses a plug 5 of a straw 4 housed in the outer tube 3 with a push rod 6 of the transplanter main body 2. The fertilized egg in the straw 4 is extruded by the stopper 5 and injected into the uterus through the injection port 7 on the peripheral surface of the tip of the outer tube 3 to be transplanted.

Hereinafter, a cow will be described as a typical example. When transplanting a fertilized egg to a cow, put the fertilized egg in a test tube, or a container such as a straw, and hang it from the neck to keep it warm with the skin, or put it in a small box made of heat insulating material, Carry to the location of the cow where the fertilized egg will be transplanted. When transplanting, if a test tube is used, refill it into a straw and set it in the transplanter. If shipped in a straw, set the straw in the transplanter.

The transplanter in which the straw is set is inserted into the uterus of a cow to transfer a fertilized egg.

"Problems to be solved by the device" However, since the transfer of the fertilized eggs that have been carried out is performed at the farm yard, at the livestock barn on the ranch, etc. There was an inconvenience that had to be done in a hygienic environment.

The present invention has been made in view of the above circumstances, and provides a fertilized egg carrier that can be immediately transplanted into a cow without carrying out preparatory operations after carrying the fertilized egg to a destination without degeneration. The purpose is to

"Means for Solving the Problems" In order to achieve the above object, the fertilized egg carrier of the present invention comprises:
An outer box made of a heat insulating material, a transplanter in which a straw filled with fertilized eggs is housed in the outer box, and a heat storage body for suppressing a temperature decrease inside are housed. It has an inner box and.

"Function" Since the fertilized egg carrier of the present invention has the above-described structure, the fertilized egg can be transferred without denaturation, and the fertilized egg can be immediately transplanted without maintaining any sterility and preparing anything. You can

[Embodiment] FIGS. 1 to 4 show an embodiment of a fertilized egg carrier according to the present invention, in which reference numeral 11 is an outer box.

The outer box 11 is formed of a heat insulating material such as Styrofoam,
The opening of the box body 11a is closed by a removable lid 11b.

The inner box 12 is tightly accommodated in the outer box 11. The inner box 12 is made of an acrylic plate, and the inner surface is lined with a heat insulating material such as Styrofoam.
An openable / closable lid 12b for closing the opening is attached. Since this inner box is sterilized when it is used, an alcohol disinfectable material is used.

In the inner box 12, a transplanter 1 in which a straw filled with a fertilized egg is set and a heat storage body (for example, a brand name: Icenon etc.) 13 for keeping the inside warm are stored and fixed, In addition, instruments such as a cervical dilation rod necessary for transplantation are also stored.

The method of fixing these in the inner box 12 is, for example, styrofoam or the like lined, the recessed parts to which the stored items are fitted are arranged, and the stored items are arranged, and the styrofoam lined with the lid 12b is used. There is no limitation on the method as long as it can be held in the inner box 12 while being transported, for example, by pressing with or by using a claw for holding the stored items on the inner bottom of the inner box.

Next, a method of using the fertilized egg carrier will be described.

First, sterilize the inner box and keep it at a predetermined temperature,
The heat storage body also has a predetermined temperature.

Then, the transplanter, the heat storage body, and the like are housed and fixed in the inner box, which is put in the outer box and hermetically sealed. If necessary, store this in a cardboard box and carry it. During this time, the inner box is insulated by the outer box and kept warm by the internal heat storage body, the rate of temperature drop is extremely slow, the temperature drop width until reaching the destination is narrow, and the fertilized egg is hardly denatured.

Immediately after arrival, the transplanter is taken out and the fertilized egg is transplanted to the waiting cow.

In this way, transplantation is carried out using the prepared equipment as it is without any preparatory operation, so that transplantation can be carried out easily and hygienically even at the farm yard, the ranch barn or the like.

Next, the heat-retaining property of the fertilized egg carrier and the conception rate of the fertilized eggs carried will be described with reference to Examples.

Example 1 An inner box was heated to 36 ° C., four 200 g packs of Icenon heated to 36 ° C. were put in the outer box, and the outside temperature was adjusted to 4 ° C., 10 ° C., 25 ° C. The time-dependent change of the temperature in the inner box was measured by changing each. The results are shown in FIGS. 5, 6 and 7.

As is clear from these figures, when the outside temperature is 4 ° C,
Holds 30 ° C or higher for up to 2.5 hours, and approximately 26 ° C after 4 hours
The change was similar at 10 ° C. Outside temperature
In the case of 25 ° C, it was kept at 30 ° C even after 4 hours.

Example 2 A straw filled with fertilized bovine eggs was set in a transplanter,
Using the inner box, the outer box, and the heat storage body of Example 1 under the same conditions, the transportation time was changed over 6 months from July to December, and the cells were transplanted to cattle to examine the conception rate. The results are shown in Table 1.

The time required for transplantation was in the range of 30 minutes to 3 hours, but the conception rate did not decrease as the elapsed time increased.

Example 3 When the same transportation tool as in Example 1 was used under the same conditions, the fertility rate by month was examined from July to December for those having a transportation time of 2 to 3 hours. The results are shown in Table 2.

The reason why 100% in August in Table 2 is because the number of cases is small. In this way, an almost constant conception rate can be obtained regardless of the change in ambient temperature from month to month.

[Effect of Device] As described above, by using the fertilized egg transporter according to the present invention, the temperature change during transportation of the fertilized egg is reduced, its denaturation is suppressed, and the fertilized egg is transplanted to the transplanter in the field. There is no need for preparatory operations such as setting straws that contain rice, and easy and hygienic transplantation can be performed in unsanitary places such as farm gardens, a constant conception rate is obtained, and livestock multiplication It is extremely effective for
