Poultry Farming

A dynamic Agribusiness

Fast adoptable

Renumarative

Helps in food security of the

country

BUT WHAT IS HAPPANING IN THE POULTRY

INDUSTRY TODAY ?

Transformation of poultry husbandry to industry and integrations.

Manipulation of marketing strategies- to face ever - narrowing profit margins

Leads to compromise in management, nutrition and health coverage

Multi age groups and increasing density of flocks and

Closeness of farms in a given area

ISSUES DEFINING BIOSECURITY TODAY &

TOMORROW

Bird perform better than ever because of good genetic potentiality and nutrition but their immune system has not necessasarly followed the same trend.

Discovery of newer immunosuppressive agents and Mycotoxinsand their prevention.

problems and losses due to infectious diseases like-ND,IB, IBD, MD, IBH,etc.

Human health concern -consumers now demanding risk free & safe food

EVALUTION OF FLOCK HEALTH

DEPENDS ON

The number of farms in the area

presence of endemic and epidemic

diseases

Application of biosecurity programmes

adopted to separate farm circumstances

WHAT ARE THE MAJOR DISEASES OF POULTRY

CONCERN TODAY ?

BACTERIAL : E.coli, Salmonella ,coryza,

fowl cholera & Mycoplasma

VIRAL : Ranikhet, Gumbaro ( IBD),

IBH/HHS Marek`s. IB & REO

FUNGAL : Aspergillosis .

Candidiosis.

PROTOZOAN : Coccidiosis.

HOW CAN WE RESPOND ?

Use of antibiotics is not a solution for

solving the problem -Drug resistance.

Vaccine development takes time and no

use on variants by a single vaccine

Therefore

GO BACK TO BASICS

CLEANLINESS IS THE KEYWORD

HACCP at Farm level

HACCP at Feed mill

HACCP at Water management

SANITATION AND BIOSECURITY IS THE

ANSWER !

WHY BIOSECURITY IS ESSENTIAL ?

Management helps good performance.

Nutrition helps to maintain the life, and

health for production.

Medication and Vaccination helps in

prevention of some disease to some extent..

But, A GOOD SANITATION/ BIO-SECURITY PROGRAMME is a vital factor for disease prevention

WHAT IS BIOSECURITY ?

Measures and Methods adopted to stop entry of disease organisms in to the farm.

A method to secure a disease free environment in the farm.

A method of production and profitability through disease control programmes.

WHAT IS BIOSECURITY ?

BIOSECRITY IS INFORMED

COMMON SENSE to avoid germs.

NOT BRING THE GERMS TO BIRDS OR

NOT BRING POULTRY TO GERMS.

HOW DO DISEASES SPREAD FROM

BIRD TO BIRD ?

BIRD WITHDISEASE

Exhaled airInfected eggs

Litter/Droppings

Feathers/DandruffInfectedbirds

Dead birds

WHAT IS THE MODE OF SPREAD OF

DISEASE ?

Vertical spread : -Trans - ovarian transmission From EGG-to-CHICK

Horizontal spread :

a) Vectors

- Flies, BeetlesRodents

- Inanimate objects: Equipments,Faecal matter,

Feathers & Dandruff

b) Nutritional - Feed and Water

WHY DO WE NEED BIOSECURITY ?

To reduce the infections -Freedom from disease

To avoid environmental pathogen challenge

To reduce morbidity & mortality

To improve good feed conversion

To boost good growth rate and production

To reduce cost of production

To reduce cost of medication

1. CONCEPTUAL BIOSECUTRY

concentrations of poultry of the same or

different species.

CONCEPTUAL BIOSECUTRY

Location of major or minor roads and the

movement of commercial and back yard

poultry.

Proximity of large lakes,tanks and rivers---

------migratory flyways

Location of multi age farms-laying units

2. STRUCTURAL BIOSECURITY

Fence the farm area to prevent

trespass

Fencing of house area with

secured gates.

Decontamination area for vehicles and foot wear.

STRUCTURAL BIOSECURITY

Proper store for feed-vermin free storage.

Bird and rodent proofing housing

Concrete flooring for proper cleaning.

Separate feed,litter and equipment

storage area away from live-birds.

3. OPERATIONAL BIOSECURITY

Remove the litter and manure from the shed

wash flooring with plain water

sprinkle caustic soda flakes on the floor@1kg/100sq.ft

Soak caustic soda with water and spread it all over the flooring area and leave it for 3-4hours

OPERATIONAL BIOSECURITY

Wash the roof, beams. trusses, cages,side

walls,curtains and all accessories inside the

shed with jet of plain water -(hot water is

preferable)

Wash the shed with2%solution of washing

soda(2kgs/100lit.water)

Use a suitable disinfectant to clean the

floor.

OPERATIONAL BIOSECURTY

Use the flame gun to clean the shed

wash all the accessories like

feeders,waterers,brooders with jet of

water and then with washing soda solution

. -use of a

disinfectant is recommended

sun dry all equipments

OPERATIONAL BIOSECURTY

Apply white wash to the shed

inside -use one part of lime and three parts of bleaching powder.

place new bedding-paddy

husk,wood shavings,maize cob

powder for deep litter.

place all accessories like waterers,

feeders,brooders in their places.

OPERATIONAL BIOSECURTY

Cover the shed with curtains and

spray the disinfectant to words

ceiling-Environmental spray

FUMIGATION: 2Kgs of potassium permanganate with 4liters of formalin for 1000

Sft.of shed area.

Keep the shed closed and covered

OPERATIONAL BIOSECURTY-6

For GUMBORO affected area /

sheds a final spray of -X-185,- 4

ml/litre of water chloramine-T need

to be sprayed.

OPERATIONAL BIOSECURTY

For automatic watering systems -remove

all water from pipes and flush the pipes

with a descaler cum disinfectant solution

need to be applied.

Then Flush the system with plain water.

LITTER DISPOSAL

Removal of litter, faecal matter ,debris,

feathers and dispose away from the

poultry premises.

Treat the litter with larvecide insecticides.

Use organic matter for Proper composting

manure making or production of bio gas.

Avoid use of litter as manure around

poultry farm.

BIOSECRITY OF SURROUNDINGS

Cleanup thoroughly six feet around the

buildings

Remove all the vegetation, organic matter-

litter,feathers,debris and decaying material

Provide proper drainage to avoid water

pools.damps or marshy areas

Cut off wild growth of trees,grass etc. to

avoid perching of wild birds

SUMMERY

Biosecurity should be thought out, planned and implemented in a wider perspective.

Operational procedures are to be properly documented and communicated to each and every employee,so that they are implemented strictly.

Proper understanding and communication of biosecurity is very vital
