Abstract

Culled breeding ostriches weighing 130-160 kg yield about 25 kg fat tissue that could possibly beused for supplementing human and animal diet.Cholesterol content of breast fat – 80 mg/100 g tissue – from the breeding ostrich females (n = 6) culledand slaughtered at the age of five years appeared similar to that reported of beef and lamb adiposetissue. In a sum of 17 fatty acids (FA) determined, the mono- and polyunsaturated FA accountedfor 37.51 and 38.84%, respectively. The ratio polyunsaturated/saturated FA in breast fat of culledbreeding ostrich females appeared higher than reported for other avian species.It is concluded that fat from culled breeding ostriches can be used as an additive to human or animaldiet, thus allowing the farmer to gain more from ostrich production. Further research is needed oncomposition and properties of adipose tissue of ostriches, including slaughter, as well as breeding272birds culled at different ages.
