Research Description This study is related to the previous works of the proponents and will be conducted to determine the effect of different time period of feed withdrawal/fasting before slaughter on the pig’s carcass characteristics and meat quality. Specifically, the study aimed to determine the optimum time for feed withdrawal on the pigs prior to slaughter with no effect on the carcass trait and quality, determine if shrinkage in live weight is lower in fasted animals than in unfasted animals, determine if carcass losses are part of the shrinkages in live weight, and to compare the effect of different fasting time interval on the carcass weight. Also, it seeks to determine the effects of feed withdrawal on residual gut fill, meat pH, water holding capacity, liver weight and meat quality, as well as the economic impact of the effect of feed withdrawal.

Research Accoplishments This project is completed and now finalizing the technical report to contain the complete information on the effect of feed withdrawal on residual gut fill, meat pH, water holding capacity, liver weight, meat quality and the recommendation regarding the economic impact of the effect of feed withdrawal.
