The effects of dietary treatments on fatty acid compositions of
broiler breast and thigh meat are shown in Tables 3 and 4, respectively.
Dietary supplementation with 1.0% and 2.0% PB resulted in a
significant reduction in the proportion of stearic acid (p = 0.001)
and PSFA (p = 0.003) in broiler breast meat. Among individual
MUFA, the oleic acid content was significantly higher (p = 0.004)
in the 1.0% PB supplemented group, whereas the PMUFA was
higher in both the 1.0% and 2.0% PB supplemented group
(p = 0.004). The proportion of eicosapentanoic acid (p = 0.001)
and Pn 3 fatty acids (p < 0.01) in breast meat of broilers fed
0.5%, 1.0% and 2.0% PB supplemented diets were higher than those
of broilers fed non-supplemented diets; however, no difference
was recorded for individual or Pn 6 fatty acids. In addition,
1.0% and 2.0% PB diets significantly increased the ratio of
USFA/SFA (p = 0.007). Although there were no significant differences,
birds fed 0.5% and 2.0% PB supplemented diets tended to
have higher PUFA/SFA (p < 0.08) and n 6/n 3 (p < 0.06) ratios
in their breast meat.
