Abstract
Essential fatty acids play a part in many metabolic processes such as immune system, and cardiovascular
system. A lower ratio of omega-6 to omega-3 fatty acids or increased omega-3 fatty acids in human diet was
more desirable in reducing the risk of the chronic diseases. Hence, the objective of this study was to determine
fatty acid composition from goat and sheep adipose tissues with two different rearing regimens, grazing and
confinement. Ten young male crossbred goats and sheep were equally divided into two groups by their species
reared on either grazing or confinement. Analysis of data as a 2 x 2 factorial combination in Completely
Randomized Design showed that different species did affect fatty acid compositions and no significant
differences were found by either rearing regimens in fatty acid composition in perirenal adipose tissues. The ratio
of the saturated to unsaturated fatty acid was significantly higher (P<0.01) in goats than that found in sheep.
But, the effects of rearing and species-rearing interaction were not observed on this ratio. Moreover, there was
significantly higher (P<0.05) α-linolenic acid (C18:3 ω3) in sheep adipose tissue than goats in both rearing
regimens. Thus, ω6/ω3 ratio tended to be lower in sheep than goats. Perirenal adipose tissues from goat and
sheep contained 4.02 % and 4.57 % polyunsaturated fatty acids (PUFA), respectively.
