Joining
ewes on lucerne can stimulate more eggs to be released from the ovaries.
According
to research Merino ewes grazing on lucerne prior to ovulation to improve
ovulation rates could play a big part in increasing conception rates.
Ewes that
were joined on the green pasture were in better condition and showed a greater
percentage of twins results when scanned.
Research showed 12% more lambs in the
mob of ewes that grazed on lucerne during joining and 10% more twins. Ewes were
in condition score two-three before joining. It just goes to show there are big
gains to be made using lucerne not just for fattening prime lambs but also for
the Merino.
In
South Africa it is generally recommended that lucerne be planted in the autumn.
