The ‘Good Clover Bad Clover’ project is a three-year project that commenced in April 2017 and aims to increase awareness of the potential issues and improve management strategies to deal with oestrogenic clover.

Key messages

Four problem sub-clover species Yarloop, Dinninup, Geraldton and Dwalgenup.

Oestrogenic clovers are responsible for a variety of symptoms in sheep including reduced ewe fertility, difficult births, prolapse of the uterus, urethral blockages in wethers and udder development in maiden ewes and wethers.

Paddock assessments have confirmed the widespread presence of oestrogenic clovers in the South East and Kangaroo Island.

Growers are encouraged to assess their own paddocks for the presence of problem species and their potential impact on their flock.
