(ration WCR against RPF and RPFA), and effect of HMBi (ration RPF against RPFA). P values ≤0.05 were regarded as significant,
P ≤ 0.10 as tendencies. Therefore the effect of fat is the difference among CON and WCR + RPF + RPFA diets, the effect of fat
source it is the difference among WCR and RPF + RPFA diets, and the effect of HMBi it is the difference among RPF and RPFA
diets.
