Abstract:

Artificial insemination (AI) technology is an advanced assisted reproductive technology,it can improve the efficiency of breeding,but due to the unique reproductive characteristics of cats,the development of cat AI technology is limited.In recent years,many researchers and clinical veterinaries have used mature AI techniques from other species,combined with feline unique characteristics to optimize and innovate cat AI technologies such as semen collection,semen quality assessment,semen preservation,stimulation of female cat ovulation,and artificial insemination,for example:A new and practical urinary catheterization technique for collecting cat semen have been developed;Based on the traditional semen quality assessment,researchers began to use fluorescent staining,flow cytometry,and in vitro fertilization technique to evaluate the quality of sperm;Researchers explored the effects of different extenders formulas and freezing procedures on the preservation of male cats semen and tried to use ultra-rapid cryopreservation to preserve the genetic material of male cats,and also explored the differences in the use of different hormones to induce estrus and ovulation in female cats;As well as the influence of different parts,methods and timing of the insemination on the pregnancy of female cats and so on.Although these new technologies have already demonstrated their potential for practical application in experimental animals,there are still some problems,such as complicated operations,high costs and lower-than-expected results.As a result,the application of AI in cats is limited,and is not as widely used as dogs or other species.In the future, further researches and explorations are needed to meet the requirements of clinical use.This paper reviewed the research progress on various aspects of cat AI technology in order to provide reference for further research and application of this technology.
