Long-acting boar semen diluting powder and preparation method thereof

Abstract

The invention provides a preparation method of long-acting boar semen diluting powder. According to the method, 26-36 g of glucose, 3-7 g of dry chicken egg-yolk powder, 3-6 g of sodium citrate, 1.5-2.5 g of aminoacetic acid, 1.0-2.0 g of disodium hydrogen phosphate, 1.0-2.0 g of ethylene diamine tetraacetic acid disodium, 2.0-4.0 g of potassium sorbate, 1.0-2.0 g of calcium propionate, and 0.005-0.02 g of gentamicin powder are taken; the powdery raw materials taken according to the previous quantities are evenly mixed together so that the boar semen diluting powder is obtained. The preparation method of the dry chicken egg-yolk powder comprises the following steps: cooking a fresh chicken egg, taking out the egg yolk and drying the egg yolk to obtain dry chicken egg-yolk powder with the moisture content of 1-10%. The nutrient solution for diluting boar semen prepared by the raw materials provided in the method and distilled water contains a nutritional agent, a diluting agent, a buffering agent, a pH regulator and an antibiotic, as well as a preservative and a bacteriostatic agent, and can be preserved for 0-12 days under the condition of a constant temperature ranging from 15 to 20 DEG C.

Description

technical field [0001] The invention relates to a porcine semen dilution powder for preparing a porcine semen diluent and a preparation method thereof, in particular to a composition of the porcine semen dilution powder. Background technique [0002] A boar's ejaculate contains far more sperm than is required to fertilize a sow. In the process of artificial insemination of pigs, the pig semen can be diluted multiple times with the nutrient solution that can dilute the pig semen. The diluted pig semen not only increases the capacity, but also allows the pig semen to be stored for a certain period of time. More sows are inseminated, thereby improving the breeding efficiency of boars, and greatly increasing the reproductive rate of excellent boars. [0003] When diluting pig semen, the nutrient solution prepared from pig semen dilution powder and distilled water can be used. Pig semen dilution powder is a powder product, which is prepared by mixing powder raw materials. Gene...

Problems solved by technology

[0004] In the prior art, the pig semen diluted with the above-mentioned nutrient solution is stored at a constant temperature of 15-20°C for a short period of time, usually 5-7 days. The nutrient solution prepared with this pig semen dilution powder Diluted porcine semen is not suitable for use in occasions that require a longer storage time for porcine semen
