Abstract

|
This study was conducted to investigate the influence of dietary mugwort and crab shell powder on physico-chemical properties in meat sample of Korean Native Chicken meat(KNC). KNC were randomly assigned to one of the three dietary treatment: 1) control(commercial feed) 2) T1(commercial feed supplemented with s% mugwort powder) 3) T2 (commercial feed with 5% crab shell powder). 120 KNC raised for 21 weeks.
They were feed one of the experimental diets for 10 weeks and slaughtered The proximate composition of all treatments was no significantly difference. The shear value was not significantly among control and treatment group (P$gt;0.05). The WHC (Water Holding Capacity) of control was higher than those of T1 and T2. The heating loss of T1 was the highest followed by control and T2. Cholesterol contents of T1, T2 was rather lower than that of control(P$lt;0.05). Especially, the T2 showed the lowest cholesterol among other treatments.
There were no significantly different in meat color(L*, a*, b*) and sensory evaluation between control and T1, T2. Among fatty acids, oleic acid contents of control and T2 were higher than that of T1. Unsaturated fatty acid and saturated fatty acid ratio was T1 $lt; control $lt; T2. Total amino acid contents of T2 and control were higher than that of T1.
