Technology in breeding farms - artificial insemination
I have been a snack reporter for more than a year as a “rural reporter†and I have been able to say some ways to raise pigs. However, when I first visited a pig farm as a “technicianâ€, I contacted pigs for artificial insemination. It is not easy to know that pig farming is difficult. As the most effective means of breed improvement, starting from 2008, some large breeding farms in Harbin began to try artificial insemination. Hailong Raw Pig Breeding Co., Ltd. is a large-scale pig farm with an average annual population of over 4,000. The breeding pigs here are all brought directly from the United States. The price per head is around RMB 10,000. It is the breeding season. Every day, farmers come here to buy semen. Therefore, breeding boars must regularly breed boars. On April 26, after careful consultation with the technicians, the reporter walked into the sperm collection room and became a “picking technicianâ€. Pigs are not stupid. Their noses are very good. Special odors are emitted when the sow is estrus. The boars are very sensitive. The technician first sprays the gilts on the sows when they are in heat. Immediately after the smell, I got excited and took a ride. The reporter strictly followed the procedure and placed the fresh food bags containing semen in a thermos cup to ensure maximum hygiene. The reporter took steps to first extrude the residual urine of the boar, and then began to collect sperm by flushing the net breeder with water. After more than ten minutes, he finally completed the sperm extraction. The reporter has already found both feet numb. It is understood that farm technicians need to collect dozens or hundreds of semen every day during the breeding period. With the semen collected by the reporter, the technicians immediately went to the lab to compare, because only the semen with a survival rate above 95% could be used. After a few minutes, the results came out. Because of the general technique, the reporter's "work" was barely qualified. The smell of breeding pigs in the hands of the journalists during the process of picking was stingy and smelly, and it was not reduced many times after washing. Later, the reporter learned from the pig farm that mining is only the first step in artificial insemination. Semen is diluted with distilled water and refrigerated. The expiration date is only 7 days. Therefore, the breeder's semen is very precious, and the annual sales revenue of the semen from the Hailong breeding farm can reach more than 10 million yuan.
