Ratite birds are generally sturdy and live long (80% livability). Mortality and health problems in emus are mainly in chicks and juveniles. These include starvation, malnutrition, intestinal obstruction, leg abnormalities, coli infections and clostridial infections. The main causes were improper brooding or nutrition, stress, improper handling and genetic disorders. Other diseases reported were rhinitis, candidiasis, salmonella, aspergillosis, coccidiosis, lice and ascarid infestations. Ivermectin can be given to prevent external and internal worms at 1 month interval beginning at 1 month age.
In emu, enteritis and viral eastern equine encephalomyelitis (EEE) were reported. In India, so far few outbreaks of Ranikhet disease were recorded based on gross lesions but were not confirmed. However, the birds vaccinated for R.D at the age of 1 (lasota), 4 (lasota booster) weeks; 8, 15 and 40 weeks by mukteswar strain gave better immunity.
