Synchronization makes it easier to AI (artificially inseminate) multiple sows at one time- making it easier on the farmer to monitor fetal growth and predict births.

The boar is introduced to the estrus sow- the boar then roots around the female, sniffing and grunting to solicite the female into standing. When the sow becomes stationary the boar then mounts.

Price, humans can test the sow's immobility response in estrous sows. This can be tested by applying pressure to the sow's back when a male is within a short distance allowing the female to see, smell and hear. If the female stands immobile, she's ready to be mounted. ]]> 2018-03-06 21:23:08 UTC https://padlet.com/emma_j_7897/o8ghiux4tn7o/wish/238906904 emma_j_7897 https://padlet.com/emma_j_7897/o8ghiux4tn7o/wish/238910443 The boar is rooting on the female, following her, smelling her and vocalizing. ]]> 2018-03-06 21:32:46 UTC https://padlet.com/emma_j_7897/o8ghiux4tn7o/wish/238910443 emma_j_7897 https://padlet.com/emma_j_7897/o8ghiux4tn7o/wish/238911344 Pros:
- More diverse genetic pool
- 100% controlled
- Eliminates need for boar

Cons:
- Greater cost 
- Requires a professional ]]> 2018-03-06 21:35:33 UTC https://padlet.com/emma_j_7897/o8ghiux4tn7o/wish/238911344 emma_j_7897 https://padlet.com/emma_j_7897/o8ghiux4tn7o/wish/238916084 20-30% of all female swine in production are artificially inseminated.
