A technique for inducing ectopic antler growth through antler tip transplantation

Abstract

This invention discloses a method for inducing ectopic antler growth through antler tip transplantation, belonging to the field of antler tip transplantation technology. The method includes the following steps: after anesthetizing the deer, the hair on the area to be transplanted is scraped and disinfected. Then, a wound is cut and a small pouch is made. The antler tip is then inserted into the small pouch, and the wound is sutured. This invention cuts off the tip of the newly formed or regenerated antler and transplants it to the forehead, top of the head, or leg. During the transplantation process, the skin (such as the scalp) can transform the antler tip into seed cells, giving it stem cell characteristics, thereby initiating the formation of antler stalks and antler growth, and antler regeneration. This ectopic antler, like the original antler, becomes ossified antler in autumn. The antler falls off the following spring, and a new antler, larger than the original, regenerates from the fallen antler. This transplantation method does not affect the growth of the original antler, and each deer can harvest two more ectopic antlers per year, effectively increasing antler yield.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pilose antler tip transplantation, and particularly relates to a method for transplanting pilose antler tips to induce ectopic antler growth. BACKGROUND

[0002] At present, deer farms need to be pruned every year, that is, the pilose antler tips of one-year-old early growth pilose antlers (pilose antlers grown by deer in the first year, generally single-branch) are cut off, so that the single-branch pilose antlers can grow into multi-branch pilose antlers, or even pilose antlers close to the size of adult pilose antlers. Generally, the small pilose antler tips cut off are discarded. If the discarded pilose antler tips can be transplanted ectopically to initiate the growth of horn handles and pilose antlers, and regenerate pilose antlers, not only can the discarded pilose antler tips be effectively utilized, but also a new way to increase the yield of pilose antlers is provided. SUMMARY

[0003] The present application aims to provide a method for transplanting pilose antler tips to induce ectopic antler growth, so as to at least achieve the purpose of increasing the yield of pilose antlers.

[0004] The technical purpose of the present application is achieved by the following technical scheme:

[0005] A method for transplanting pilose antler tips to induce ectopic antler growth, comprising the following steps:

[0006] After the deer is anesthetized, the transplantation site is shaved and disinfected, a wound is cut and a small pocket is made, then the pilose antler tip is inserted into the small pocket, and the wound is sutured.

[0007] As some embodiments of the present application, the transplantation site includes the forehead, the top of the head, or the leg.

[0008] As some embodiments of the present application, the length of the wound is 2-5 cm.

[0009] As some embodiments of the present application, the pilose antler tip is a peeled pilose antler tip (i.e., a pilose antler tip with the pilose skin peeled off) or a pilose antler tip with the pilose skin (i.e., a pilose antler tip with the pilose skin retained); wherein the length of the peeled pilose antler tip is 1.5-2.5 cm, and the length of the pilose antler tip with the pilose skin is 2-3 cm.

[0010] As some embodiments of the present application, when the transplantation site is the forehead, the small pocket is made and the specific operation of the small pocket is as follows:

[0011] The scissors are inserted into the wound and bluntly peeled off the scalp and skull cap towards the front to make a small pocket, and then the scalpel is inserted into the small pocket to scrape and remove the bone membrane on the skull cap.

[0012] As one possible implementation method of this application, during the process of stuffing the peeled velvet tips into the small pocket, the bottom of the velvet tips is first placed on the skull with the periosteum removed, and then the incision is sutured.

[0013] As one possible implementation method of this application, during the process of stuffing the velvet tips with skin into the small pocket, a tenon-and-mortise structure is made at the bottom of the velvet tips and on the skull to connect the velvet tip tissue. After the velvet tips are placed in place, the scalp and velvet skin are sewn together.

[0014] As one possible implementation method for this application, the transplantation time is spring or summer.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention involves cutting off the tip of a newly formed or regenerating antler and transplanting it to the forehead, top of the head, or legs. During the transplantation process, the skin (such as the scalp) can transform the antler tip into seed cells, giving it stem cell characteristics again, thereby initiating the formation of antler stalks and antler growth, and antler regeneration. This provides a new way to further increase antler production. Like the original antler, this ectopic antler becomes ossified in autumn and falls off the following spring. From the fallen antler, a new antler grows that is larger than the original. The transplantation method of this invention does not affect the growth of the original antler. Each deer can harvest two more ectopic antlers per year, greatly increasing antler production. Attached Figure Description

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0026] In the prior art, it is known that deer skin can induce the peri-antler bud (AP, the tissue basis of antler initiation) and peri-pedicel (PP, the tissue basis of antler regeneration) to initiate antler initiation and regeneration respectively (Li et al, 2011), but there is no report on the induction of ectopic antler initiation by antler tip transplantation.

[0027] Based on this, the present application provides a method for inducing ectopic antler initiation by antler tip transplantation, comprising the following steps:

[0028] After the deer is anesthetized, the transplantation site (including the forehead, the top of the head or the leg) is shaved and disinfected, then a wound is cut and a small pocket is made, and then the antler tip is inserted into the small pocket and the wound is sutured.

[0029] In the present application, the tip of the initiated or regenerated antler is cut off and transplanted to the forehead, the top of the head or the leg. During the transplantation, the skin (such as the scalp) can make the antler tip become a seed cell and regain the characteristics of stem cells, thereby initiating the initiation of the pedicle and the antler, and the regeneration of the antler thereafter. After transplantation, about half of the transplantation sites can grow antlers in the same year, and the rest can grow antlers in the second year. After two years, the ectopic antlers can grow relatively large, providing a new way to further improve the yield of antlers.

[0030] In order to further improve the success rate of transplantation, as some embodiments of the present application, the length of the wound, the type and length of the antler tip are further limited, i.e. the length of the wound is 2-5 cm; the antler tip is a peeled antler tip or a skin-covered antler tip; wherein the length of the peeled antler tip is 1.5-2.5 cm, and the length of the skin-covered antler tip is 2-3 cm. In actual transplantation, it is found that if the antler tip is too short, the growth potential is not good, and if the antler tip is too long, the transplanted tissue is not easy to survive. Therefore, by controlling the length of the antler tip, the growth and survival rate of the transplanted tissue can be effectively improved. In addition, during actual transplantation, the bottom of the transplanted antler tip should be flat. If it is not flat, the growing antler will not only be skewed in direction, but also lack of blood supply (mainly because the transplanted tissue and the tissue to be transplanted cannot be fully fused), which affects the growth potential of the antler. In addition, the growth time of the antler tip provided is 10-20 days, which is the best and can maximize the survival rate of the transplanted tissue.

[0031] In order to further promote the healing of the bottom of the dehorned antler with the frontal bone, as some embodiments of the present application, the preparation of the small pocket and the treatment of the periosteum are further limited, that is, when the transplantation site is the forehead, the preparation of the small pocket and the specific treatment of the periosteum are as follows:

[0032] The scissors are inserted into the wound, and the scalp and skull are bluntly dissected forward to make a small pocket, and then the scalpel is inserted into the small pocket to scrape the periosteum on the skull for removal.

[0033] In the initial development, the transplanted antler does not fuse with the frontal bone of the transplantation site, so it is necessary to chisel a groove in the frontal bone and repair the bottom of the antler into a shape that can be inserted into the groove, and then insert the antler and suture the skin. It was later found that the antler can be completely fused with the frontal bone as long as the periosteum of the transplantation site is removed, so the step of chiseling the frontal bone is omitted, paving the way for the application of this technology to production. Specifically, if the periosteum of the forehead site receiving the transplanted antler is not removed when the antler is transplanted, it will hinder the healing of the bottom of the antler with the frontal bone, so only free antlers can grow, which cannot grow very large due to insufficient blood supply, and therefore have no development value.

[0034] In order to further promote the healing of the bottom of the dehorned antler with the frontal bone, as some embodiments of the present application, the preparation of the small pocket and the treatment of the periosteum are further limited, that is, when the transplantation site is the forehead, the preparation of the small pocket and the specific treatment of the periosteum are as follows:

[0035] In order to further promote the healing of the bottom of the dehorned antler with the frontal bone, as some embodiments of the present application, the preparation of the small pocket and the treatment of the periosteum are further limited, that is, when the transplantation site is the forehead, the preparation of the small pocket and the specific treatment of the periosteum are as follows:

[0036] In order to further improve the success rate of transplantation, as some embodiments of the present application, the transplantation time is further limited, that is, the transplantation time is spring or summer.

[0037] The transplantation method is described in detail below in conjunction with specific examples.

[0038] Example (with deer forehead as transplantation site)

[0039] In current production practice, deer farms have to prune every year ( Figure 1), that is, cutting off the tip of the one-year-old early growth of the Mao Tang Rong (the first year growth of the deer antler, generally single branch) deer antler, so that the single branch of the Mao Tang Rong can grow into a multi-branch, even close to the size of the adult deer antler.

[0040] The general cut-off small antler tip is discarded, but if the transplantation method of the present application is used, the sawn-off two sides of the antler tip are immediately buried under the skin of the forehead of the deer, so that two ectopic deer antlers can grow ( Figure 2 ), and this transplantation does not affect the growth of the in-situ deer antler, and two ectopic deer antlers can be harvested per year per deer.

[0041] The specific transplantation method is as follows:

[0042] S1 After the deer is anesthetized, the hair on the forehead of the deer is first shaved clean and disinfected; then a 2-5 cm long incision is made along the connecting line of the front edges of the two horn handles with a surgical knife ( Figure 4 ), a pair of scissors is inserted into the incision to bluntly peel off the scalp and skull to make a small pocket; then a surgical knife is inserted into the small pocket to scrape the bone membrane on the skull to remove it;

[0043] S2 When using the skinless antler tip for transplantation, the skinless antler tip (the antler tip of the selected branch deer antler or early Mao Tang Rong is shaved, disinfected, cut off 2 cm, and the skin is removed to stop bleeding) is inserted into the small pocket, and the bottom of the skinless antler tip is seated on the skull with the bone membrane removed ( Figure 5 ), and then the incision is sutured.

[0044] When using the skin antler tip for transplantation, a mortise and tenon structure is made at the bottom of the skin antler tip (the antler tip of the selected branch deer antler or early Mao Tang Rong is shaved, disinfected, cut off 3 cm, as shown in Figure 3 , and then the skin is removed to stop bleeding) and the skull of the deer to be transplanted ( Figure 6 ) to connect the antler tip tissue, and after the antler tip is placed in place, the scalp and the skin are sutured together.

[0045] After the antler tip transplantation is performed according to the above method, the success rate of transplantation is 100%, and about half of the transplanted sites can grow antlers in the same year ( Figure 7 ), the rest grow antlers in the second year, and the ectopic deer antlers can grow relatively large after two years ( Figure 8 and Figure 9 ). Among them, the antlers transplanted in the first year are single branches not more than 10 cm; in the second year, they can reach 15 cm; and in three years or more, they can reach more than 20 cm.

[0046] The foregoing is considered as illustrative only of the principles of the application. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the application to the exact construction and practice described. Accordingly, all such variations are intended to be included within the scope of the present application as defined in the following claims, along with full authority to use equivalent methods and materials such variations are covered by such claims.
