Boar semen dilution powder and preparation method thereof

Abstract

The invention relates to a method for preparing boar semen dilution powder, comprising the following steps: taking 45-55g of dextrose powder, 2.5-3.5g of sodium citrate dehydrate, 0.8-1.2g of sodium ethylene diamine tetracetate, 500-800 thousand units of penethamate, 500-1000 thousand units of dihydrostreptomycin and 2.5-3g of egg yolk dry powder; and evenly mixing the dextrose powder, the egg yolk dry powder, the sodium citrate dehydrate, the sodium ethylene diamine tetracetate, the penethamate and the dihydrostreptomycin to obtain boar semen dilution powder. The method for preparing the egg yolk dry powder comprises the following steps: cooking fresh eggs, taking out yelk and drying the yelk into egg yolk dry powder with a water content of 7-10percent. In the invention, the egg yolk dry powder has rich phosphatidylcholine to ensure the normal metabolism of the semen and has the functions of nutrition and semen shock prevention after a lower limit period at a preserving temperature. The boar semen diluted by adopting the invention has a preserving period not less than five days, ensures a fertility rate above 95percnet and a birth number of 11.6.

Description

technical field [0001] The invention relates to a porcine semen dilution powder for preparing a porcine semen diluent, in particular to a composition and a preparation method of a porcine semen dilution powder. Background technique [0002] The amount of sperm contained in the semen of a boar ejaculate is far more than the amount required for fertilization of a sow. In the process of artificial insemination of pigs, the pig semen can be diluted multiple times with a pig semen diluent. The diluted pig The semen not only increases the capacity, but also allows the semen to be stored for short-term or even long-term use, so as to inseminate more sows, thereby improving the breeding efficiency of boars, and greatly increasing the reproductive rate of excellent boars. When diluting porcine semen, porcine semen dilution powder and distilled water can be used to prepare porcine semen dilution liquid. Pig semen dilution powder is a powder product. The components of pig semen diluti...

Problems solved by technology

In the prior art, there is no component to prevent sperm shock in the pig semen dilution powder. When the pig semen diluted with the pig semen diluent prepared by this pig semen dilution powder is stored in a constant temperature refrigerator, when the temperature is at the lower limit of the storage temperature After a certain period of time, the sperm will produce shock, which will affect the effect of use
