In this experiment, a device was developed and evaluated to deliver nematophagous fungus Duddingtonia flagrans to sheep by using local fungal isolate. Sterilized barley grains supporting the fungal growth were incorporated into straw based complete feed blocks (CFB). The viability of fungal spores was assessed for the biological control of ovine Haemoncus contortus. Two groups (fungus-treated and control without fungus), each consisting of five Garole x Malpura lambs (about 6-9 months old) which were artificially infected with 6000 Haemonchus contortus larvae per lamb. The treated group received fungus incorporated CFB (400g block per lamb delivering 6 million chlamydospores) daily during 7 weeks. Fungal chlamydospores survived well in CFB with very little moisture (11.8%) when stored at room temperature. Mean larval development was significantly (P
