Problems solved by technology

In addition, the preservation of semen will also affect the fertilization rate of sows. The existing technology is not standardized, resulting in a large number of bacteria and microorganisms flowing into the semen during semen collection, resulting in a decrease in the quality of boar sperm and the conception rate of sows. Lower the amount, increase the cost of farming

Abstract

The invention discloses a treatment method of boar semen and a use method of the treated boar semen, and belongs to the technical field of artificial insemination of boars, and the treatment method comprises the following steps: after collection, rapidly observing the color of original semen, measuring the pH value and measuring the volume; preserving the temperature of the diluent at 30-35 DEG C for 30-45 minutes, immediately putting the original semen into the diluent, sampling, and evaluating the sperm motility rate and the sperm density; performing isothermal dilution and uniform mixing on the diluent and the original semen, and filling semen bottles with the uniformly mixed diluted semen; and preserving in a dark place at 15-20 DEG C. The treatment method can supplement energy substances for the pig sperms, especially has the special functions of protecting the acrosome structure of the sperms, inhibiting sperm activity before insemination, prolonging the service life of the sperms and improving the insemination capacity, and has the tendentiousness effect of reducing the number of birth of boars and piglets. The method can be used for instant insemination or normal-temperature preservation. After the feed is used, the sperm quality of boars is improved, the conception rate of sows is increased, and the breeding cost is reduced.

Description

technical field [0001] The invention relates to the technical field of artificial insemination of pigs, in particular to a method for disposing of pig semen and a method for using the processed pig semen. Background technique [0002] The disposal of semen from breeding boars has become an important part of pig production. In the prior art, the formula and preparation method of swine semen diluent are mostly used, and there is a lack of comprehensive treatment method for swine semen. The ejaculated semen of pigs is not sterile. It contains many bacteria, some of which have flagella and move like sperm, but are much smaller than sperm and can be easily seen under a microscope. The raw materials for preparing the diluent cannot avoid microbial contamination, and can only be sterilized after the diluent is prepared. If the semen diluent is used directly without sterilization, there is a risk of causing infection in the sow's uterus. At present, semen diluent cannot be steril...
