Disease management
Turkeys are relatively more resistant to some of the diseases as compared to chicken. Infection from Marek's disease and Infectious Bronchitis are extremely rare. Ranikhet disease and Coccidiosis occur only in mild form. The most common diseases are Fowl pox, Fowl cholera, Fowl typhoid, Mycoplasmosis, Blue comb and round worm infections. Although effective drugs are available for prevention and treatment of most of these diseases, greater emphasis should be placed on prevention.
- Although turkeys are resistant to various diseases but the veterinary care is required at initial stages and for vaccinations etc.
- The turkeys are completely resistant to Marek's and Infectious Bronchitis, Ranikhet, Fowl pox and Coccidiosis occur in mild form.
