Method of emasculation

Abstract

The invention provides an emasculation method which can not only safely and effectively castrate a sire, but also improve the growth speed and meat yield of the sire. The method includes the following steps: pre-preparation, immobilization, disinfection, operation and hemostasis and disinfection. Compared with conventional emasculation methods, the invention is different in that during the emasculation operation, only the testis of the sire is extirpated and the epididymis and the spermatic cord are reserved and are fixed with tunica vaginalis; the remaining gonad can produce male hormone, thus the sire can have enough male hormone to simulate the growth of the organs, not only increasing meat yield but also depriving the sire of sexual capacity and reproductive capacity. The invention can effectively improve production level and economic performance and has the good emasculation effects that the castrated sire grows fast and has a big body and high meat yield, thus the method is applicable to emasculation operations on various male livestock as pigs, oxen, sheep and rabbits.

Description

Technical field [0001] The invention relates to a method for castration of male livestock. Background technique [0002] Castration is an important technical measure to remove or destroy the testes, epididymis, sperm and other reproductive organs of livestock, so that the livestock will lose their sexual function, so as to improve the breed of livestock and improve the performance of animal husbandry. At present, there are many methods for male castration at home and abroad, such as: blood castration, bloodless castration, drug castration, ultra-low temperature freezing castration and immune castration, etc. Among them, the commonly used methods are surgical castration and drug castration. These castration methods all still have certain deficiencies no matter from a technical point of view or from an economic point of view. [0003] For example: the drug castration method is a new castration technique developed in recent years. It uses the method of drug injection to dest...

AI Technical Summary

Problems solved by technology

Using this method, the specific effect depends on many factors such as the finished chemical drug product used and the concentration and dosage injected, the age and type of castration of livestock, and the proficiency of the user. Its main disadvantages are two. The dose should be accurate, and the injection amount of the chemical agent should be determined according to the age of the castrated animal and the size of the testis. If the dose is too large, the inherent sheath on the surface of the testis will rupture and ulceration will easily occur; if the dose is insufficient or too small, the entire testis cannot Tissue necrosis will affect the castration effect; second, the injection site of the medicine must be accurate, if the medicine liquid leaks into the scrotum at the tunica albuginea, it will cause severe swelling, and if the medicine liquid leaks into the tunica albuginea, it will easily cause inflammation of the scrotum. Neurotoxic when injected into the testicles May cause convulsions, loss of coordination, difficulty walking, and sometimes death

Although some complications can be cured, it takes a lot of energy to nurse, consumes a lot of medicines, and affects the speed of weight gain; large animals need to be taken care of by people, which is time-consuming and labor-intensive, and brings losses and a lot of inconvenience to the masses.

[0005] More precisely, the biggest disadvantage of the above-mentioned various castration methods is that the use of these traditional castration methods all have an inhibitory effect on the growth of male animals. Practice has proved that the growth rate of male animals will be significantly reduced after castration. The growth rate of male animals after castration is generally similar to that of female animals, which is mainly related to the endocrine of the gonads. Because the above-mentioned methods of castration all cause the male animals to completely lose their sexual function, which leads to disorders of gonad endocrine and tissue metabolism. The feed is converted into tissues well, so that the livestock body is poorly developed, the individual grows slowly, and the meat yield is reduced, which ultimately affects the economic benefits of the livestock breeder
