Problems solved by technology

Since farmers did not take effective heat preservation measures for normal temperature pig semen, when the temperature exceeds the constant temperature range of 16-18°C for normal temperature pig semen, the sperm will die from cold and heat shocks, and the vitality of the semen will be affected; when the temperature is exposed to direct sunlight and during transportation Strong vibration and collision will cause sperm shock and death, affect the vitality of semen and the number of effective sperm, thus affecting the conception rate and farrowing rate of sows

Embodiment 1

[0018] Add agar gel at 16°C to the bottom of the heat preservation box, put 40 mL of packaged semen into it, and measure the temperature of the heat preservation box at any time with a thermometer. When the outside temperature changes and the temperature in the heat preservation box drops to 15°C, add a warming agent to the bottom of the heat preservation box. The temperature riser is a mixture of 1.219g of calcium oxide and 150g of water to raise the temperature to 17.2°C.

Embodiment 2

[0020] Add 17°C agar gel at the bottom of the heat preservation box, put in 50 mL of packaged semen, and measure the temperature of the heat preservation box at any time with a thermometer. When the outside temperature changes and the temperature in the heat preservation box drops to 15°C, add a warming agent to the bottom of the heat preservation box. The temperature riser is a mixture of 3.658g of calcium oxide and 180g of water to raise the temperature to 19.6°C.

Embodiment 3

[0022] Add 18°C ​​agar gel at the bottom of the heat preservation box, put in 80 mL of packaged semen, and measure the temperature of the heat preservation box at any time with a thermometer. When the external temperature changes, the temperature in the heat preservation box is lowered to 15°C, and the temperature riser is added to the bottom of the heat preservation box.

Abstract

The invention belongs to the technical field of artificial insemination, relates to a heat-preservation method, and in particular relates to a heat-preservation method for boar semen. The heat-preservation method for the boar semen is characterized by comprising primary heat-preservation and secondary heat-preservation, wherein the primary heat-preservation is gel heat-preservation, and the secondary heat-preservation is warming agent or cooling agent heat-preservation. The method is easy to operate, requirements on equipment are low, and the equipment is convenient to carry and use; a cooling agent can be recycled in a concentration and crystallization treatment way, so that the storage and transportation cost is greatly lowered.

Description

technical field [0001] The invention relates to a heat preservation method, in particular to a heat preservation method of pig semen. It belongs to the technical field of artificial insemination. Background technique [0002] Normal temperature semen is the basis for artificial insemination of pigs. The quality of normal temperature semen products directly affects the progress of genetic improvement of pigs, the coverage rate of fine breeds, conception rate and litter size, and even affects the service life of fertile sows. [0003] The best temperature for storing porcine normal temperature semen is 16-18°C, but if the insemination is performed within a short period of time, the temperature is allowed to reach 25°C, but not lower than 15°C. Semen is very sensitive to temperature changes, x-rays, ultraviolet radiation, transportation, etc. The existing technology requires that the normal temperature semen produced by the breeding boar station must be transported to the pi...
