Abstract

After a reduction in price during and after the First World War, ostrich feathers have once again become an important part of the income of ostrich producers in recent years. Looking at the feathers harvested from mature ostriches, it was found that male ostriches had a 16% higher weight for total feather than females. It was also found that this difference in feather weight between males and females was reduced for ostriches 10 years and older. South African Black ostriches had a 30% higher total feather weight than Zimbabwean Blues. Heritability estimates for the weights of the different feather types were low to moderate, and high at 30% for total feather weight. Genetic correlations between categorised feather traits were moderate (49%) to very high (91%). The present results show that feather quantity can be improved by selection in ostriches.
