Artificial insemination technology has been widely used in the production of foxes in China. Fox artificial insemination refers to using artificial aids to take the male fox semen, after microscopy meet the requirements and after processing and preservation, and then use the device to input male fox sperm into the estrous female fox reproductive tract in a breeding method. Fox artificial insemination technology is the simplest and most effective method adopted for the purpose of breeding foxes and production of commercial foxes, and is an important means for scientifically raising fox and realizing the modernization of fox production.
Advantages of improving the utilization of elite fox The fox artificial insemination is the most effective way to improve fox breeds, and can promote variety renewal and improve fur quality. Through artificial insemination technology, the high-quality gene of excellent male foxes is rapidly promoted, the number of excellent populations (bred pure Finnish foxes) is expanded, and the varieties, strains of the improved foxes, and the production performance of foxes for the skin are improved. At the same time, the poor male foxes can be eliminated and the amount of foxes raised can be reduced, thus reducing the cost of raising fox and improving the overall economic efficiency.
To overcome some of the difficulties in self-incompatibility, such as male and female mothers are not good match, the female animal refused to match, the female animal is difficult to match with the waist and the mother animal genital malformations, using artificial insemination can be solved. It is also possible to carry out crossbreeding between different foxes, breed hybrid foxes, and produce hybrid hides (blue fox, silver black fox).
Reduction of disease transmission Male and female foxes for artificial insemination are generally healthy foxes that have been tested for blood tests and reproductive diseases. They are strictly in accordance with the artificial insemination procedures to minimise contamination during semen collection and semen processing. It can reduce the occurrence and spread of some diseases, thereby improving the fertility rate, number of births, and utilization of the female fox. However, some male beasts suffer from diseases, and diseases transmitted through semen can be transmitted through artificial insemination. Therefore, public foxes that inseminate artificially must undergo disease detection.
Save manpower, material resources, financial resources, improve economic efficiency Compared to artificial insemination and natural mating, the number of feeding public foxes is relatively reduced, saving some of the artificial, breeding, sheds and funds. Even if a proper public fox station is re-established, the total economic benefit will increase. If pure fox sperm is purchased, more economic benefits will be created.
Disadvantages If the level of production of the fox house itself is not high and the technology is not enough, artificial insemination is likely to result in increased fox meteitis, low conception rate, and low number of births. It is recommended that technical personnel be trained to learn the technology first, and then conduct small-scale artificial insemination tests; or adopt a combination of natural mating and artificial insemination, and follow the continuous improvement of the production level and technology, and then promote.
