DILATATION OF THE ORIFICE OF THE TEAT.

The results of the above operation not always proving permanent, and cicatricial contraction often following after a few weeks’ time, forced dilatation by means of the conical tubes shown (Fig. 327) has been generally substituted for it. Three instruments of varying thickness are usually sufficient. Forced dilatation may be effected at a single operation, and has not the drawback of causing cicatrices.

ABLATION OF THE MAMMÆ.

Ablation of the mammæ is rather frequently necessary, principally in cases of gangrenous mammitis, of prolonged, continuous suppuration, or of grave mammitis, where death would otherwise follow.

Provided the anatomical structure of the parts is known (Fig. 327) ablation does not present any insuperable difficulty.

In the cow, either two lateral quarters or the entire udder must be removed. The lines of incision through the skin should first of all be traced.
