The effects of an oestrogenic preparation on blood and liver copper concentrations and teat length of sheep



The effects of an oestrogenic preparation on blood and liver copper concentrations and teat length of sheep



N Z J Agr Res 10(3/4): 345-347



Dally dosing of an estrogenic preparation in the form of an oral contraceptive for three months to wethers and ewes did not affect their blood Cu or liver Cu. The teat lengths of both ewes and wethers in the dosed group increased significantly during the dosing period. The mean increase for wethers was significantly greater than that for ewes. From the clear evidence mat estrogenic activity was not associated with altered Cu levels the inference is drawn that estrogenic activity may not itself be a cause of the chronic Cu poisoning that sometimes occurs in sheep grazing subterranean clover.
