'''CATTLE'''
* Many doses from a single ejaculate.
* Inseminate 6 hours post-oestrus.
* Success rate is 70% from a single insemination (same as natural service)
* Farmers inseminate the herd themselves.
* A hand is used to grasp the cervix of the cow and a delivery pipette is inserted through the cervix into the uterine body which is felt with the index finger.
* Allows further advance of the semen than natural insemination would reach (anterior vagina).
* Only 2-8 million live sperm are required in the semen to achieve fertility in cattle.
