title: Effect of marketing treatments and transportation on feeder pig performance.
abstract: During four 6-wk trials, 376 university-raised, crossbred feeder pigs were used to determine the effects of fasting (no feed or water) vs providing feed plus water or water alone at the simulated market and a 563-km transport on shrinkage and subsequent health and performance. Providing feed and water or water alone during a 12-h market simulation for Trials 1, 2 and 4 or a 24-h period for Trial 3 did not affect subsequent rate of gain (ADG) or feed efficiency (F/G) compared with pigs fasted during the market stay. However, overall shrinkage (market phase plus transportation) of pigs provided feed and water at the market was less (P less than .05) than for fasted pigs (4.0 vs 8.4% for Trials 1, 2 and 4; 4.5 vs 11.8% for Trial 3). Transporting the fasted or nonfasted feeder pig 563 k did not affect subsequent health or performance. Overall shrinkage of the fasted pigs that were transported 563 km vs those that were not transported during Trial 4 was not different (8.8 vs 9.1%; P greater than .05). In conclusion, one-owner feeder pigs can cope with the stress of fasting and transporting long distances without any extended detrimental effects on subsequent health and performance.
