Ca. Morris et al., OSTRICH SLAUGHTER AND FABRICATION .2. CARCASS WEIGHTS, FABRICATION YIELDS, AND MUSCLE COLOR EVALUATION, Poultry science, 74(10), 1995, pp. 1688-1692
Seven male and seven female ostrich carcasses were fabricated to deter
mine the effect of sex on the yield of bone, fat, and lean on a weight
and carcass percentage basis. The 10 heaviest muscles of the ostrich
carcass were removed, weighed, and reported on a carcass percentage ba
sis. Muscle color differences also were determined for 10 selected mus
cles. Sex did not affect carcass composition or muscle color. Across s
exes, ostrich carcasses contained 26.9% bone, 9.2% fat, and 62.5% lean
. Of the lean portion, 66.2% was found in the 10 major muscles of leg
and thigh. The Gastrocnemius, Iliofibularis, and Fibular's longus were
the three largest muscles from the carcass. There were differences (P
< .05) in color between ostrich muscles. Muscles of the inside thigh
region were the darkest in color and the Iliotibialis cranialis was th
e brightest, cherry red in color.
