摘要
Abstract
In recent years,due to the dual effects of African swine fever and the COVID-19 epidemic,the pig breeding industry has been seriously affected.The batch production management model has been widely used in pig farms,which has greatly improved the efficiency of pig production.Timed artificial insemination is a key technology to realize batch production of sows and can effectively increase the annual number of farrowings per sow,save semen consumption,and simultaneously reduce the risk of disease transmission among pigs,thus showing broad application prospects.This paper reviews the commonly used hormones,technical applications,influencing factors,existing problems and corresponding solutions of timed artificial insemination in sows,aiming to provide technical references for the batch production mode of pig farms.Timed artificial insemination technology can be divided into simplified timed artificial insemination and precise timed artificial insemination.The former requires estrus detection and is easy to operate,while the latter does not require estrus detection and is more commonly used in batch production.The effectiveness of this technique is affected by factors such as semen quality,hormone quality and safety,the number of inseminations,and feeding management.At present,there are still problems such as high incidence of follicular cysts,high number of white stillborn piglets,and reduced farrowing rate in gilts.These problems can be improved through the establishment of puberty for gilts,optimization of hormone use,and precision feeding and management.In the future,the timed artificial insemination technology can be further improved by developing new semen extenders,optimizing insemination procedures,improving the accuracy of estrus and ovulation detection,developing new deep artificial insemination catheters,and enhancing hormone potency,thereby promoting the healthy development of batch production.关键词
