Pig Breed Registration Technology

The registration of breeds is the basis of all breeding work. It is to collect, edit, count, analyze, and publish the breeding data of the breeds of related breeds in order to promote the protection and improvement of breed resources. Its purpose is to ensure that each breeding pig has a legal identity; to ensure that each breeding pig has a clear source and complete genealogy; to ensure the purity of the variety; and to ensure the quality of genetic evaluation data. The registration includes the breeder's individual number, individual basic information, and individual change registration information.

(1) Individual number

According to the national uniform pig numbering system for individual numbering, the numbering principle is: the first two digits are indicated by uppercase English letters (DD means Duroc, LL means Landrace, YY means Great White, HH means Hampshire); No. 3 to No. The 6th place uses uppercase English letters to indicate the field number (Beijing Cattle Breeding Genetic Evaluation Center), and the 7th place uses numbers or English letters to indicate the breakout number (use 1 to 9 first, then use A to Z, without splitting breeding pigs) Field 1); 8th to 9th digits indicate the year of the individual's birth; 10th to 13th digits indicate the yard number; 14th to 15th digits indicate the serial number .

(2) Individual basic information

General information: breed, strain, birthplace name, birthplace code, date of birth, litter size, weaning date.

Individual information: ear number (6 digits), gender, birth weight, left and right papilla, stress genotype, weaning weight.

It is recommended to register the litters at the same time to avoid duplicate entries of the same information and to reduce human errors in data entry.

Note: If purchased abroad, the following information should also be registered: country of birth, breeder farm, breed, date of birth; breeding pigs purchased from other domestic breeder farms have been registered for breeding pigs, so registration is not required.

(3) Individual Change Registration

The registration content includes: individual number, departure date, reason of departure (death, elimination, sale) If it is sold, record the purchase field.

(4) Enter the above information into GBS software and upload the data to the species registration database through the website of Beijing Germplasm Genetic Evaluation Center (http://) to complete the application for species registration. After reviewing and registering at the Genetic Evaluation Center, the breeding farm will be You can query and print information on the registered pigs in this field.

Laser Distance Meter

Laser distance measure is a very convenient tool for various types of applications in industries, construction and house decoration. Laser distance meter is a very useful device which gives accurate measurement of distance, area and volume especially in large areas such as rooms, apartments, buildings, real estates, factories, warehouses, infrastructures, gardens, roads, and many other applications requiring accurate results for distance , area and volume measurement.

Trade your heavy tape measure for laser rangefinder, which let you simply take measurements with one hand. No matter your job, the laser rangefinder will help you measure much farther, with greater accuracy and in more situations, saving you money and time.
