Embodiment 1

[0019] A long-acting diluted pig semen powder, which is prepared by mixing the following components by weight: 30.00 g of glucose, 6.53 g of trisodium citrate dihydrate, 2.73 g of citric acid monohydrate, and 2.20 g of ethylenediaminetetraacetic acid , sodium bicarbonate 0.90g, potassium chloride 0.50g, tris 5.50g, bovine serum albumin 4.00g and antibiotic enrofloxacin 0.20g.

[0020] experiment method:

[0021] (1) The raw materials of the examples are of analytical grade, weighed, vacuum-packed and then sealed to obtain a diluted powder, which is stored at a temperature of 2-8° C. and a relative humidity of 50% or less.

[0022] (2) When using dilution powder, stir with double distilled water heated to 35-37°C, mix evenly, and set the volume to 1000ml to obtain semen dilution, which is used for dilution of pig semen after 1.5 hours.

[0023] (3) After the pig semen is collected, use a sperm density meter to test the density of the pig semen with normal smell and color, and ...

Embodiment 2

[0033] An optimal formula of pig semen long-acting dilution powder is prepared by mixing the following components by weight: 27.69 g of glucose, 6.03 g of trisodium citrate dihydrate, 2.52 g of citric acid monohydrate, 2.03 g of ethylenediaminetetraacetic acid, Sodium bicarbonate 0.83g, potassium chloride 0.46g, tris 5.08g, bovine serum albumin 3.69g and antibiotic enrofloxacin 0.18g.

[0034] experiment method:

[0035] (1) The raw materials of the examples are of analytical grade, weighed, vacuum-packed and then sealed to obtain a diluted powder, which is stored at a temperature of 2-8° C. and a relative humidity of 50% or less.

[0036] (2) When using dilution powder, stir with double distilled water heated to 35-37°C, mix evenly, and set the volume to 1000ml to obtain semen dilution, which is used for dilution of pig semen after 1.5 hours.

[0037](3) After the pig semen is collected, use a sperm density meter to test the density of the pig semen with normal smell and col...

Abstract

The invention belongs to the technical field of pig propagation and particularly relates to pig semen long-acting diluting powder and an application thereof. The pig semen long-acting diluting powder is prepared from the following components in parts by weight: 27-30g of glucose, 6-7g of trisodium citrate dehydrate, 2-3g of citric acid monohydrate, 2-3g of ethylenediamine tetraacetic acid, 0.5-1g of sodium bicarbonate, 0.3-0.6g of potassium chloride, 5-6g of tris(hydroxymethyl)metyl aminomethane, 3-4g of bovine serum albumin and 0.1-0.3g of antibiotic enrofloxacin. An optimized formula comprises 27.69g of glucose, 6.03g of trisodium citrate dehydrate, 2.52g of citric acid monohydrate, 2.03g of ethylenediamine tetraacetic acid, 0.83g of sodium bicarbonate, 0.46g of potassium chloride, 5.08g of tris(hydroxymethyl)metyl aminomethane, 3.69g of bovine serum albumin and 0.18g of antibiotic enrofloxacin. Semen can be kept as long as 11-13 days. The pig semen long-acting diluting powder can be applied to the auxiliary propagation of pigs.

Description

technical field [0001] The invention belongs to the technical field of pig reproduction, and in particular relates to a long-acting dilution powder of pig semen and an application thereof. Background technique [0002] Pig artificial insemination technology is a breeding method that uses artificial equipment to collect boar semen, inspects the quality and dilutes the semen, and then injects the semen into the reproductive tract of estrous sows with equipment to replace the natural mating of boars. In the 1980s It is rapidly popularized all over the world. At present, in Europe and North America, where it is widely used, the penetration rate has exceeded 80%. It is an important means for scientific pig raising and modernization of pig production. It has the following advantages: (1) Saving boars, and reduce the number of times each boar is used, overcome time and regional differences, and can conveniently and timely breed; (2) save manpower, material resources, and financial ...
