Pre-Rigor Beef Quality Assessment of Bali Cattle Subjected to Different Finishing Systems in Malaysia
The study was carried out in an attempt to assess meat quality
of Bali cattle finished in 3 different systems. Twenty one bulls were selected
from an existing herd under an oil palm plantation and randomly assigned to
120 days of feeding in; Integration-INT (n = 8), basal energy Feedlot-F (n =
6) and high energy Feedlot-FB (n = 7) System. All animals were humanely slaughtered
at a commercial abattoir. Samples of Longissimus Dorsi (LD), Supra Spinatus
(SS) and Semi Membranosus (SM) muscles were collected and prepared accordingly
for the determinations of pH, cooking loss, shear force and color (L* and a*)
values. The animals finished on Integration (INT) demonstrated higher L* values
(p<0.05) in SS muscle and lower L* values (p<0.05) in both LD and SM muscles.
Lower cooking losses (p<0.05) were observed in LD and SM muscles from the
INT group. However, there was no difference in pH, a* (redness) and shear force
values among the treatments and these were consistently shown in all three muscles.
The results from this study demonstrate the influence of finishing system on
Bali cattle meat quality.
