1. Old boars, boars used in production should have been eliminated because they have reached the corresponding age or have a relatively long service life (more than 3 years), aging, physical decline, poor semen quality.
2. In order to meet the production needs and the adjustment of the population structure, in the aspect of quantity adjustment, breed renewal, selection and retention of strains, and disease purification of breeding boars, the unqualified breed characteristics, appearance deviation from the breeding target or body type were assessed as unqualified and descendants. Boars with high segregation of traits or high deformity rates should be selected and eliminated with planning and purpose.
3. Low libido, reserve boars that are more than 10 months old and cannot be used or suffer from congenital genital diseases should be eliminated in time; boars are degraded due to excessive use or lack of vitamin A, E, minerals in feed, etc. , Low sexual desire, disequilibrium, boars that have not been improved due to increased feeding and management, vitamins and minerals addition, and proper sports should be eliminated.
4. Boars with organic testicular lesions (swelling and atrophy) should be eliminated after treatment and strengthening of feeding and management.
5. Boars with long-term unqualified semen quality (five weeks and four fine inspections), and boars with fewer litters should be eliminated.
6. The boars are regularly blood-tested and found that serious infectious diseases should be eliminated immediately.
7. Boars are injured due to exercise, breeding, or other reasons (such as clefthoof, arthritis, etc.), so that boars cannot stand or become unstable when they climb or climb, lose their ability to breed, and have not improved after treatment. Eliminated.
8. If the body condition of the boar is too fat or too thin to cause breeding difficulties, after treatment, there is still no obvious improvement and should be eliminated.
9. Boars, aggressive tempers, boars attacking staff members, such as masturbating, biting wounded sows, and attacking breeders, should be eliminated.
IT02S, is JRT new product in the early 2019, which is a single-point LiDAR sensor, also called tof distance sensor. With a micro size of 46x17x7mm, customers can widely use in many Laser Measurement Solutions. The lidar distance sensor can measure 12m short-range with high frequency up to 100hz. It's great for Unmanned Aerial Systems. If you need us send you data sheet and spec for this products, offering sample as well, pls tell us, thank you.
