Embodiment

[0018] 1. Preparatory work before semen collection:

[0019] 1. Prepare diluent by mixing 1000ml of distilled water with 50g of dilution powder imported from Denmark, and heat to 37°C.

[0020] 2. Put the cleaned and disinfected thermos cup on the filter paper of the semen collection bag and put it in an incubator to preheat to 37°C.

[0021] 3. Adjust the microscope, stage constant temperature plate and other semen collection tools.

[0022] Second, semen collection:

[0023] 1. Drive the boar to be collected to the semen collection room.

[0024] 2. The semen collector wears double-layer gloves, squeezes out the urine from the foreskin of the boar, and wipes it dry after strict disinfection; be patient when collecting semen until the boar is completely ejaculated.

[0025] 3. Immediately transfer the collected semen to the semen processing room.

[0026] 3. Semen processing:

[0027] 1. Put the semen on the constant temperature stage to keep the semen warm.

Abstract

The invention relates to a manual collection method for porcine semen. The manual collection method includes the following steps of 1) preparing before semen collection; 2) semen collection; 3) semenprocessing; 4) semen releasing; 5) semen storage. The manual collection method for the porcine semen is easy to operate, small in damage and not prone to pollution, has the wide application value, andcan increase porcine artificial impregnation and pregnancy success rate. The qualification rate of the semen collected and stored with the method is 95% or above, and the started stored semen is goodin sperm motility and high in pregnancy rate.

Description

technical field [0001] The invention relates to the field of animal production and reproduction, in particular to a method for artificially collecting pig semen. Background technique [0002] There are two methods of breeding animals: free mating and artificial assisted mating. The free mating method is more suitable for small groups of animals, which is convenient and trouble-free, but it is prone to reproductive tract diseases, which in turn affects the pregnancy rate. Artificial insemination technology is a key technology in animal reproduction to improve the fertility of male animals. Artificial insemination technology for pigs began in the 1930s and in my country in the 1950s, but it did not become popular until the 1990s. At present, this technology has become one of the main means of breeding pigs. The use of artificial insemination technology is conducive to the promotion of new breeds of pigs. It can reduce the labor intensity of mating sows, save the time spent ...
