Injection equipment should always be clean. A procedure that has been used is a single 5 ml dose injected under the skin, high in the neck region. Your veterinarian will provide full details of the recommended procedure, cost and withholding periods. Ram versus wether teasers Surgically sterilised rams do not require the use of chemicals, but have relatively few other advantages and many disadvantages compared with chemically treated wethers. However, an advantage would be the fact that the ram teasers need only be prepared once and are then available when required provided they are maintained in good body condition.
Poor preparation can leave the ram teasers still fertile.
Wether teasers are foolproof in this respect. The ram teasers can act as carriers of Brucella ovis and other diseases that can cause infertility or wastage in the ram flock. When the teasers are being used to concentrate lambing, the ram teasers have to be mustered out of the ewes before the entire rams are joined. The wether teasers do not have to be removed from the ewes. The ram teasers look and behave like rams and must be managed as rams.
