Abstract

This study investigated the effect of pre-slaughter feed withdrawal on live weight loss and carcass characteristics in cockerels. Twenty-five (25) cockerels were randomly assigned to five treatment groups (n=5 per group) subjected to feed withdrawal periods of 0, 6, 12, 18, and 24 hours. Live weight significantly decreased (p<0.05) from an initial average of 1307g to 1011g after 24 hours of feed withdrawal. Estimated live weight losses were 116g, 101.36g, and 62.12g at 6, 12, and 18 hours of fasting, respectively. Sensory evaluation revealed that meat from the 24-hour feed-withdrawn group exhibited superior tenderness and texture. However, meat from the 12-hour withdrawal group was deemed most acceptable by the sensory panel. Feed withdrawal did not significantly influence meat colour or flavour. The findings suggest that pre-slaughter feed withdrawal does not severely impact overall cockerel carcass yield and dressing percentage. While longer withdrawal periods resulted in more tender meat with improved texture, a pre-slaughter feed withdrawal exceeding 12 hours is not recommended due to significant live weight loss and potential economic implications for producers.
