3.2. Effect of fasting duration
The bibliographic search yielded 16 studies allowing to metaanalyze
the effect of fasting duration on the predefined attributes of
pork meat quality. These studies were based on data of 2202 animals
divided into 43 treatment groups. Fasting time in the range of 0 (no
fasting) to 72 h had a significant effect on pHu and DL48. Their CI
did not cover zero, and the null hypothesis of non significant effect
was therefore rejected. However, L*, pH45 and DL48 were not significantly
affected by fasting time (Table 1 and Fig. 2).
