Abstract:
A large proportion of the low lamb marking percentage in the agricultural regions of Western Australia was associated with the grazing of clovers with a high (>1.0%) concentration of formononetin (Lloyd Davies 1987). Some of the differences in sheep fertility between Western Australia and the eastern states may have been due to cobalt or selenium deficiency - both deficiencies being more widespread in WA than in the eastern states of Australia. This experiment was carried out on newly cleared land at the Yalanbee Research Station of the CSIRO at Bakers Hill, Western Australia.
