Like its predecessor, this publication is written for students and those professionals who choose to work at the sharp end of the pig industry and are driven by a desire to improve the environment that farmers provide for pigs. The authors describe proven monitoring techniques which can also interpret data and automatically implement adjustments to environment control systems. Readers are led through a series of case studies from commercial pig farms. Explanations of the source of problems within pig buildings are provided and augmented by graphical data which are explained in simple terms. In particular, the book makes much reference to I.T. devices already in use within other industries and speculates how these will be increasingly used to help pig farmers integrate more closely with their food chain partners.
