Abstract

The invention provides a boar sperm preservative as well as a preparation method and application thereof, and belongs to the technical field of livestock breeding. The boar sperm preservative provided by the invention is prepared from glucose, sodium hydrogen carbonate, sodium citrate, EDTA, citric acid, trihydroxymethyl aminomethane, L-cysteine, levofloxacin, sodium carboxymethylcellulose, bovine serum albumin and Banqing toxin-removing oral liquid. Compared with a conventional diluent Zorlesco, the boar sperm preservative provided by the invention has a better preservation effect of boar sperms, can improve the antibacterial ability of boar semen, and prolongs the storage time of the boar sperms.

Description

technical field [0001] The invention relates to the technical field of animal husbandry, in particular to a pig sperm preservation agent and its preparation method and application. Background technique [0002] In large-scale pig production, the main cause of the abnormally high culling rate of sows in pig farms is reproductive diseases, and more than 50% of reproductive diseases are caused by endometritis. According to reports, compared with normal sows, sows with endometritis had a corresponding increase of 15.81 days and 30.67 days in the first mating days and 30.67 days in postpartum conception days, and a 21.36% decrease in conception rate during estrus. The increase was 0.51 times, which had a huge impact on the economic benefits of the pig farm. [0003] Studies have shown that bacteria in the diluent or semen is the primary reason for the expansion and spread of metritis. The diluent is an essential component in the preservation of semen. It can dilute, buffer, nou...
