This book presents research on sources of errors in pig weight measurements. Three studies were conducted on a New Zealand pig farm. First, finisher pigs fed ad libitum or via a liquid feeding system were weighed four times a day over a four-day period. Results showed that standardizing weighing time reduced fluctuations in pig weights....

Weekly retro- and prospective production records were obtained from three New Zealand pig farms. Observation periods on farms A, B, and C were 140, 127 and 90 weeks....
