Prevention and Control of disease in broiler chicken In poultry industry primarily emphasis is given more on prevention and control than curative measures. A suggestive disease prevention & control programme follows:
· Start with disease free stock.
· V accine chicks against Ranikhet & Merek’s disease at Hatchery .
· Use coccidiostal to prevent coccidiosis.
· Keep feed free from aflatoxins.
· Do not allow visitors or outsiders and attendants inside the poultry house unless they wear disinfected boots and clean clothing.
· Cover floor with clean litter at least 3 inches deep.
· All-in-one system of rearing should be followed to ensure minimum disease problems.
· Foot-bath provision at the entrance of the farm is must.
· Provision of adequate clean and fresh water should be available.
A)Viral chicken disease
1)Ranikhet / New Castle Disease
Symptoms:
· Af fects all the birds of the farm.
· Dif ficulty in breathing.
· Nasal dischar ge.
· iv . Anorexia.
· v . Greenish diarrhoea.
· vi. 90-100% mortality .
· Pr evention: Early vaccination with F1 followed by R 2 B vaccines
2) Mar ek’s Disease
Symptoms:
i. Af fects all the birds.
ii. Droopy wings, lameness, paralysis.
iii. 60- 70% mortality .
T r eatment :
No treatment, only early vaccination.
B)Bacterial Diseases –
1) Salmonellisis
Symptoms:
i.Chalky white diarrhoea.
ii.Pasted vent.
iii.Depression. and loss of weight.
iv .Sudden death.
v . Af fects all age groups.
Treatment:
i. Use effective antibiotic (contact nearest veterinary centre).
ii.Recovered birds act as a source of disease and thus better to cull.
2) Colybacillosis
Symptoms:
i) Affects all age groups.
ii) Diarrhoea.
iii) Dizziness.
iv) Swelling of joints.
v) Oedematous comb and wattle.
vi) Mortality rate – 90%.
Treatment:
Antimicrobials (contact nearest veterinary centre).
C)Fungal Diseases –
1) Br ooder pneumonia / aspergillosis
Symptoms:
i) Affects chicks.
ii) High mortality .
iii) Respiratory problem.
iv) Swollen eye and head.
T r eatment:
Use antifungal (contact nearest veterinary centre).
D)Helminthic Diseases-
Symptoms:
i) Af fects mostly layer birds.
ii) Inappetance.
iii) Poor body growth.
iv) Ruf fled feather .
v) Diarrhoea.
T r eatment:
Use anthelmintic every two months (contact nearest veterinary centre)
E)Protozoan Disease s-
1) Coccidiosis
Symptoms:
i) Bloody diarrhoea.
ii) High mortality rate.
T r eatment:
1)Proper management.
2)Use anticoccidiosis (contact nearest veterinary centre)
BIO – SECURITY MEASURES IN A BROILER F ARM
Bio-security is a practice designed to prevent the spread of disease onto your
farm.
Bio-security has three major components:
1.Isolation.
2.T raf fic Control.
3.Sanitation.
Bio-security Measur es :
1. Fencing .
2. Keep visitors to a minimum .
3. Limit visitations to other poultry farms .
4. Keep all animals and wild birds out of poultry houses .
5. Practice sound rodent and pest control programs.
6. Inspect flocks daily and recognize disease symptoms.
7. Good ventilation and relatively dry litter .
8. Keep areas around houses and feed bins clean.
9. No exchange of feed and equipments .
10. Disinfection and sanitisation of poultry house & equipments.
Marketing of Br oilers:
Marketing should be planned.
A successful project will depend on the good market and the price of fered.A suggestive disease prevention & control programme follows:
