Prediction of meat quality in Bali cattle using ultrasound imaging
Abstract: The objective of
this study were to predict carcass quality characteristics in Bali cattle using
ultrasound imagery. The Number of samples were 81 heads of Bali cattle consist
of bulls (62 heads) and cows (19 heads) with various age ranging from 1 to 6 years
were collected their body weight and carcass qualities including backfat
thickness (BF), longissmus dorsi thickness (LD), rump fat thickness (RF), rump
thickness (RT), marbling score (MS) and the percentage of intramuscular fat
(PIF). Those were estimated using ultrasound performed on 4.5-6,5 MHz frequency
with depth of 8.8-13 cm. The BF, LD, MS and PIF measurement were applied on
12th-13th ribs, while the RT and RF measurement were conducted between ischium
and illium. MS determination was calculated using Aus-Meat standard, while PIF
was analysis based on Deaton and Rouse (2000). Body weight and carcass quality
among traits were analyzed using descriptive and correlation procedures. The
results showed that performance of body weight and carcass quality differs
between Bali bulls and Bali cows, as well as among the age variations.
Correlation analyses among traits (body weight and carcass quality) showed
strong positive correlation (P<0.05) ranging from 0.291 to 0.938. In
conclusion, ultrasound imaging method could be used to estimate carcass quality
characteristics in Bali cattle.
