Pig management

First, from the start of breeding or introduction of breeding pigs, a herd archive should be established to clearly record the breeding and production status of each breeding pig. It is best to archive the species, put into production batches or time, and renumber the unclear numbers to ensure that each pig's ear number is clearly not repeated. It is advisable to record the status of each time of weaning after recording each breeding and each littering.
Second, the simple method of numbering the pigs in the yard when they are farrowing is to use an ear deficiency number, which generally requires 1st pig. Detailed preparations for farrowing records require the number of sows, the size of the breeding boar, breeding time, litter size, litter size, number of live piglets, stillbirth, and mummy.
Thirdly, record the abnormal situation of each pig every day, and clean up once every week for special conditions (such as disease, mutilation, non-estrus sows and old and weak pigs, etc.). The group cleans up once. Some pigs were put forward to phase out reports in time.
