The flexibility is imparted by being performed. As shown in FIG. 2, a closing member 4 for closing the opening of the distal end of the expansion tube 2 is attached to the distal end of the expansion tube 2. The closing member 4 has a substantially closed cylindrical shape made of a soft resin such as vinyl chloride. A cover portion, that is, a portion covering the opening of the expansion tube 2 bulges in a convex shape and is formed in a curved surface shape. Things. Further, the closing member 4 is formed with a cross-shaped notch 5 in a portion of the lid formed in a curved shape. This cut 5
Is for inserting a transplant tube of the implanter main body 3 to be described later. Before the transplant tube is inserted, the notches 5 are in close contact with each other because the closing member 4 is made of a soft resin. When the dilatation tube 2 is inserted into the cervix from the vagina of a domestic animal such as a sow, a germ or the like is prevented from entering the dilatation tube 2 from the cut 5 of the closing member 4 under such a configuration. It has become. The closing member 4 is provided with a radius at a boundary between the lid and the cylindrical portion and at a rear end edge of the cylindrical portion, so that when the expansion tube 2 is inserted into the body of a domestic animal such as a sow, an unexpected event occurs. Do not hurt the livestock body.

And a connecting portion 13 connected to a rear end of the holding portion, a grip portion 14 having a larger diameter than the connecting portion 13, and a mounting portion 15 formed at the rear end of the holding portion 14. To
It has a tubular thin tube 16 that passes through the connecting portion 13 from the rear end face of the grip portion 14 and protrudes further from the connecting portion 13. The connection portion 13 is connected to the transplant tube 6 such that a portion of the thin tube 16 protruding from the connection portion 13 communicates with the inner tube 8 of the transplant tube 6.
It is attached and fixed to the transplant tube 6 in a state of being inserted therein. The mounting portion 15 has a mounting hole 17 penetrating therethrough. The mounting hole 17 is formed so as to gradually decrease in diameter toward the distal end side, that is, toward the grip portion 14 side, and is disposed so as to communicate with the inside of the thin tube 16 at the distal end side. This is for directly or indirectly attaching a container such as a straw tube or a syringe that stores a fertilized egg.

Through the cervical canal C so that the closing member 4 of the transplant tube 2 reaches the vicinity of the uterine constriction D. In this case, since the dilatation tube 2 has flexibility, an elongated spiral cervical canal peculiar to a sow.
In C, it follows the shape sufficiently, and its closing member 4
Is made of soft resin and does not damage the cervix C.

Then, the insertion is further continued, and the injection part 11 at the tip is made to protrude from the cut 5 of the closing member 4 as shown by a two-dot chain line in FIG. In this case, the transplant tube 6
Since the scale is displayed on the outer skin 10, the operator can estimate the position of the injection portion 11 in the dilatation tube 2 by reading the scale, and therefore, before reaching the closing member 4, the operator can simply read the transplant tube. 6 only needs to be advanced into the expansion tube 2, and the operation can be performed quickly. Further, even after passing through the closing member 4, the transplantation tube 6 has flexibility,
In addition, since the blade 9 imparts an appropriate strength, the injection portion 11 of the transplant tube 6 can be easily advanced by operating the rear end side of the transplant tube 6. Then, the injection portion 11 of the transplant tube 6 is made to reach a desired position deep in the uterine horn E in this manner. Also in this case, the position of the injection part 11 can be estimated from the scale of the outer skin 10 of the transplant tube 6.

Then, since the diameter of the mounting hole 17 is gradually reduced toward the distal end, the straw tube 18 has one end thereof tightly fixed in the mounting hole 17. Then, a cotton plug portion for sealing the other end side of the straw tube 18 is cut off, and as shown in FIG.
9 is extrapolated to the other end of the straw tube 18.

述した種々の受精卵注入方法に対応でき望ましい。In the above embodiment, the fertilized egg is fed directly from the straw tube 18 into the mounting hole 17, but the implanter 1 of the present invention is not limited to such a use, and may be, for example, another type. After the straw tube 18 is attached to the attachment hole 17, a cylinder filled with a compressed gas such as carbon dioxide gas is attached to the straw tube 18, and the fertilized eggs in the straw tube 18 are poured out by jetting the compressed gas. Further, the fertilized egg stored and stored in the straw tube 18 is transferred into a syringe containing a pre-stored culture solution in advance, and the needle of the syringe is directly attached to the mounting hole 17, and the rod is pressed by pressing the rod in this state. The stored culture solution and the fertilized egg may be extruded. Alternatively, the compressed gas cylinder may be attached to the syringe to which the fertilized egg has been transferred from the straw tube 18 so that the fertilized egg flows out. Here, since the outer diameter of the needle base of the syringe is usually larger than the outer diameter of the straw tube 18, the mounting portion 15 of the base 7 also has an inner diameter of the mounting hole 17 larger than that when the straw tube 18 is directly mounted. Prepare In addition to directly attaching the straw tube 18 to the attachment hole 17, an adapter (not shown) having an insertion portion having the same shape and dimensions as the needle of the syringe is used, and the straw tube 18 is inserted through the adapter. 18 may be attached, in which case the base 7 is preferably of one shape and size and can cope with the various fertilized egg injection methods described above.

Injection is performed from the center of the tip of the injection hole. However, an injection hole may be formed so as to open laterally of the injection portion 11, and an inner tube may be inserted into the injection hole. An injection hole may be formed so as to open a plurality. Further, in the above-mentioned embodiment, the livestock fertilized egg transplanter of the present invention is applied to fertilized egg transplantation to a sow. However, it is needless to say that the present invention can also be applied to fertilized egg transplantation to a cow or a sheep.

For example, this expansion tube can be inserted into the cervix of a slender spiral sow. Because it can be easily inserted and expanded without damaging the cervical canal, and because the graft tube is flexible,
This makes it possible to easily reach the deep horn of the uterus via the dilatation tube. Therefore, the container containing the fertilized egg is attached to the mounting hole at the base, and the fertilized egg is pushed out of the container by a well-known pushing means such as a syringe, so that the fertilized egg can be injected into the end of the transplantation tube into a female pig or the like. It can be easily transplanted into the deep horn of the uterus from the part, which can greatly contribute to the production of excellent livestock such as pigs.
