Good Clover Bad Clover

Latest News >>

Oestrogenic clovers can significantly impact lambing percentages and these two fact sheets will help you to identify the 'bad' clovers and give you tips on how to manage your sheep while grazing oestrogenic pastures


The clovers which are highly oestrogenic are Dinninup, Dwalganup, Yarloop and Geraldton. If these clovers make up 20 percent of the pasture eaten by ewes, fertility problems could occur. For a fact sheet containing photos and descriptions click here

Handouts from the Oestrogenic Clover and EID for Sheep field day held at Richard Kirkland’s property in October can be found below.

These handouts include the  field assessment sheets for identifying oestrogenic clovers,  risk scoring paddocks and a general sub clover identification resource of the newer varieties.

Below are the contact details for the lab if you are interested in sending in samples to test for oestrogenic levels in plants, plus the details on how to collect the samples.

Post samples to: Southern Scientific Services, PO box 234, Hamilton Vic. 3300

The cost depends on the number of samples but it is about $90 for 2-5 samples.


As far as collection goes, representative sampling is required, often a cross-paddock walk taking a whole plant at ground or grazing level (your choice). Sample only the clover content of the pasture and remove any grass and weeds. Roughly chop the collected sample & subsample out at least 2 large handfuls overall & place in labelled paper bag. Freeze if accumulating samples or its late in the week. Post in paper bags so samples dry rather than sweat in plastic and use a cardboard box to post the samples.
