Introduction
Prevention and control of poultry diseases is one of the most important factors for the profitability of poultry farming business. This prime fact provides a brief overview of the importance of knowing your cost of production, and benchmarking to monitor business profitability plus how to use financial ratios to gauge future viability. Following basic factors should be kept in mind for preventing and controlling of poultry diseases.
Diseases of Poultry
The two most serious poultry diseases that must be kept out of poultry flocks are Newcastle disease and avian influenza. Poultry industry is at risk from their introduction. The compulsory vaccination program against disease has helped protect the industry against both endemic and exotic disease. Some are controlled by vaccination or medication strategies. Others are controlled by keeping them out of farms.
Routine preventative measures form the next line of defense against disease, after providing a clean and hygienic environment through good poultry farming practices. Preventative measures include:
Vaccination
Vaccination can prevent many poultry diseases. Follow a suitable vaccination program or only buy appropriately vaccinated stock.
Poultry vaccinations include:
For breeders of poultry, when vaccinating:

Parasite control
Birds that are housed on the floor and have access to pastures and outdoor areas will have greater exposure to internal and external parasites. For birds housed in these conditions, it is important to have a prevention program in place and treat as required. This helps to minimise physical stress and keep birds in good condition so they can resist disease. Control parasites by:
Remove sick birds
Regularly observe your birds for any signs of ill health or problems within the flock such as feather pecking. Remove sick chickens and other poultry from the main flock and obtain a diagnosis from a qualified person. Sick birds usually appear different to healthy birds. You can give the correct treatment once you identify the disease or problem. Keep ill birds quarantined from the flock until completely recovered. If medication is given, it is important to adhere to any withholding periods.
Multi-age flocks
When introducing younger birds into a flock of older birds, there is an increased risk of disease transfer from the older birds to the younger birds. Older birds often build resilience to diseases and disorders that younger birds have not been exposed to.There may also be an increased risk of feather pecking and social issues when introducing new birds to a flock.It is preferable from a disease perspective to run single-aged flocks. However if this is not possible and you are running multi-age flocks:
Conclusions
An adequate disease prevention program is essential to a profitable commercial poultry operation. Diseases can reduce efficiency and increase costs. Although proper management mainly parasitic control and vaccination in poultry farm can prevent from many disease and may not show immediate returns on the investment, it will be profitable in the long term.
