Research Progress on the Effect of Pregnancy Diagnosis Method and Re-artificial Insemination Scheme on Reproductive Efficiency of Dairy Cow
The development of dairy farming is an important part of the large-scale process of China's animal husbandry.In recent years,the scale of dairy farming facilities in China has continued to expand,and the milk production has increased year by year,but the low breeding efficiency has led to insufficient overall production of dairy cow and other problems still restrict the development of the industry.With the advancement of reproductive technology,the detection of the pregnancy status of dairy cow through reasonable pregnancy diagnosis methods combined with the re-artificial insemination scheme can effectively reduce the rate of embryo loss of dairy cow,improve the pregnancy rate of dairy cow,and then effectively improve the reproductive efficiency of dairy cow and create more economic benefits.This paper will summarize the commonly used pregnancy diagnosis methods of dairy cow and the influence of re-artificial insemination scheme on the reproductive efficiency of dairy cow,in order to provide theoretical reference for the application of dairy cow reproductive technology and the improvement of reproductive efficiency.
