For industrialized pig farms with a certain scale, if they want to achieve balanced production all year round and have a reasonable sow population structure, the key to pig production is to select good breeding pigs. [0003] The service life of boars is generally controlled at 2 years, and the annual renewal rate of boars is 25% to 30%. Breeding boars with the following conditions should be eliminated: low libido, gilts that have not improved after training and drug treatment; boars with testicular organic lesions (swelling, atrophy); poor semen quality, low breeding conception rate , boars with few litters; boars who have suffered from parvovi...
