Pigs (häftad, eng)

Written in response to a growing demand on the part of pig farmers, here is a text-book which will provide a working manual to which reference can be readily made.

Not all the diseases discussed in the text are of interest to pig producers in the United Kingdom but they have been included in the hope that they may be of interest to pig farmers in other countriesAlso some of the diseases discussed are subject to the restrictions under the Diseases of Animals Acts and Orders, but they have been included in the hope that owners may recognise the cardinal symptoms of these diseases and take action accordingly.
