Kualitas Karkas Domba Lokal yang Diberi Pakan Jerami Padi Fermentasi dengan Suplementasi Minyak Kedelai
ABSTRACT: The aim of this
study was to determine if supplementation of soybean oil in the ration in order
to increase conjugated linoleic acid of meat has concurrent effects on carcass
characteristics and qualities of thin-tailed sheep. Sheep were fed fermented
ricestraws supplemented with 0, 3 and 6% soybean oil. The experimental design
used was a Randomized Completely Block Design. Eighteen sheep with initial age
of 6-8 months and initial bodyweight of 17.46 ± 1.61 kg were used. The
treatments consisted of soybean oil supplementation 0, 3 and 6%. Variables
measured were carcass conformation, GR thickness, backfat thickness,
subcutaneous fat score, and kidney and pelvic fat score. Result showed that
sheep fed ration with 0 % soybean oil produced carcass with carcass
conformation score of 8.50 ± 1.05, GR thickness 11.50 ± 1.05 mm, back fat
thickness 2.67 ± 0.82 mm, subcutaneus fat score 3.50 ± 0.55 mm, kidney and
pelvic fat score 2.00 ± 0.00. Sheep feed ration with 3% soybean oil; carcass
conformation score 8.67 ± 1.21, GR thickness 11.67 ± 1.21 mm, back fat
thickness 2.83 ± 0.98 mm, subcutaneus fat score 3.50 ± 0.55, kidney and pelvic
fat score 1.83 ± 0.4. Sheep feed ration with 6% soybean oil; carcass
conformation score 9.00 ± 1.26, GR thickness 12.50 ± 1.52 mm, back fat
thickness 3.33 ± 0.82 mm, subcutaneus fat score 3.50 ± 0.55, kidney and pelvic
fat score 1.83 ± 0.41. Score of carcass conformation, thickness of GR,
thickness of back fat, score of subcutaneus fat, and score of kidney-pelvic fat
were not influenced by supplementation of soybean oil. In conclusion,
suplementation soybean oil in the ration to increase conjugetaed linoleic acid
has no significant concurrent effect on carcass quality characteristics of
local sheep.
