Abstract

© 2016. To study the effects of starting time of feedwithdrawal on behaviour during loading and lairage, and meat quality(pH, colour and drip loss) in pigs, a total of 700 pigs were distributed into two groups. One group (FARM) wasfasted for 18 h at the farm before transport and for 6 h before slaughter (including 2 h transport and 4 h lairage),while for the other group (PLANT) fasting time started at the departure from the farm (2 h transport plus 22 hlairage). Total fasting time was 24 h before slaughter for both groups. Fasting treatments did not influenceblood parameters. PLANT pigs had longer fights (P b 0.05) than FARM pigs during lairage and produced darker(P = 0.02) and drier (P = 0.03) loins. Based on the results of this study, it may be preferable to commencefeed withdrawal at the farm.
