Definitions
- the present invention relates to the artificial insemination of animals, and particularly to an improved device for artificial insemination of sheep, goats, deer and other exotic and wild animals, with a high percentage of conception.
- An object of artificial insemination is related to the ability to select and ensure the delivery of superior genetic characteristics, and to provide improved pregnancy rates.
- Pregnancy efficiency levels are critical as they are directly related to the cost of raising cattle.
- a factor that affects pregnancy efficiency levels is also closely related to the artificial insemination device and technique used.
- the applicator is passed with the straw containing the semen through the vagina to the entrance of the neck and then the semen is deposited there, pushing a metal plunger that in turn pushes a plug inside the semen carrying straw to make the semen expulsion from this straw towards the cervix.
- the cervix in this species of animals such as sheep, goats, deer and other exotic and wild animals, has a very irregular inside with numerous folds that do not allow easy access to the uterine horns, so only fresh semen with a high sperm concentration of at least 200 to 400 million sperm can be applied.
- An additional drawback of this type of artificial insemination is that semen only reaches the entrance of the cervix, not being effective for insemination with frozen semen; In addition, the sperm loses strength before it reaches fertilization of the ovule so its effectiveness is low.
- Laparoscopy device For artificial insemination in sheep with frozen semen, only one Laparoscopy device is available, which requires drilling a side of a sheep's abdomen to inflate the abdominal cavity with air in order to introduce an apparatus that allows visualization and Locate the tubes. Subsequently, the other side of the abdomen is perforated and thus introduce the artificial insemination apparatus.
- This device has a needle that is inserted through the abdominal cavity until you find the uterus where it is deposited with it, the semen.
- SCRAPIE standard microorganism of crazy cows.
- the laparoscopy method requires highly qualified personnel.
- an object of the present invention is to provide improvements in a device for artificial insemination of sheep, goats, deer and other animals exotic and wild, high efficiency and with high conception rates to reduce the associated costs of raising cattle.
- the advantages of the present invention are achieved through a device for artificial insemination of sheep, goats, deer and other exotic and wild animals, comprising a universal special insemination pipette for any semen presentation, a syringe coupled in a pipette end. Said syringe comprising a means for exerting pressure towards the insemination pipette which at its end has the semen straw inserted.
- an inseminating tip member is placed on the front of said insemination pipette covering it.
- Said device including a rigid tube of appropriate length and diameter, with the purpose of preventing semen residues from remaining in the walls of the universal pipette by the effect exerted by the pressure of the ejected liquid, through which said pipette passes inwards , the distant part of said rigid tube comprising in its upper part a piece or device of metallic or plastic material having a design of a thin metal or plastic cannula straight or with more folds and one or several holes that allow the rapid exit of semen to the uterus.
- This last device has an almost spherical seal on the tip that allows it to pass through the uterus without damaging it.

- the distant end (14) of the pipette (10) has a conical portion (20) in its interior to receive any type of semen carrier straw (shown in dotted lines) tightly.
- a semen-containing straw is cut by one of its ends and firmly inserted into the distant end (14) of the pipette (10), such that the trimmed end of the straw stops with the conical inner portion (20) of said distant end (14) and remain fixed at the distant end (14). Likewise, the free end of the straw is cut in order to mount on it an inseminating tip member of the present invention.
- the inseminating tip member comprises a pipette coupling portion (31) and a semen ejector tip (33).
- the pipette coupler portion (31) has a proximal end (34) and a distant end (35).
- the pipette coupler portion (31) is a rigid tubular longitudinal body in which its proximal end (34) has an appropriate diameter D 1 to allow insertion of the distant end (14) of the pipette (10).
- the coupling portion (31) comprises an annular shoulder (37) that serves as a stop to define the maximum distance at which the distant end (14) of the pipette (10) can be inserted into said interior coupler portion (31) and, in this way, facilitate the clamping and immobilization of the pipette inside the proximal end (34).
- the pipette coupler portion (31) has a length such that the semen straw (not illustrated) inserted at the distant end (14) of the pipette (10) can extend into the tubular body of the coupler portion of pipette (31) and be housed and protected by means of said coupling portion (31).
- the diameter D 1 of the proximal end (34) of the pipette coupler portion (31) gradually decreases towards the distant end (35), where the diameter D 2 of the distant end (35) is smaller than the diameter D 1 of the proximal end (34) in order to receive tightly and couple the semen ejector tip (33) of the inseminating tip member of the present invention as described below.
- the length and diameter dimensions of the pipette coupler portion (31) being selected in such a way as to avoid semen residues remaining in the walls of the universal pipette due to the effect exerted by the pressure of the ejected liquid.
