Abstract |
This study was conducted
to determine the effect of feeding 1.5% palm oil calcium soaps (POCS)
(135 g/head/day) on carcass and ribeye characteristics in finishing
Hanwoo steers. Feeding POCS did not affect carcass yield traits such as
back fat thickness, ribeye area, yield index, or quality traits such as
marbling, meat colour, fat colour, texture, maturity, and quality grade
at slaughter (P>0.05).
However, feeding POCS decreased yield grade at farm 1 and increased it
at farm 2 (P<0.05). Feeding POCS affected ribeye fatty acid composition
( P<0.05), increased ribeye stearic acid by 19% (P<0.005) and n-3 α-linolenic
acid by 11% (P<0.05), but did not affect the percentage of palmitic,
oleic, or linoleic acids, mono-unsaturated fatty acids (MUFA),
poly-unsaturated fatty acids and essential fatty acids or the ratio of
saturated fatty acids: unsaturated fatty acids
(P>0.05). Feeding POCS did not affect water holding capacity,
cooking loss, pH, moisture, crude protein, ether extract or crude ash of
ribeye (P>0.05). Furthermore, feeding
1.5% POCS did not affect Hanwoo steer weight
gain (P>0.05). In conclusion, feeding 1.5% POCS
to finishing Hanwoo steers changed the composition of ribeye fatty acids
without deleterious effects on carcass or ribeye characteristics and
body weight gain.
