Poultry: Contributions in Production and R&D Poultry stands 2 nd in the world meat production. Indian Poultry Sector: 8-15 % /annum... Agric. sector 1.5 to 2% /annum 6-7% per annum for egg; 15-20% for meat. IPS contribution:~0.77% to national GDP; 17% of GDP from livestock. (Meat sector ~ 66.7 % ; Egg Prod and 33.3%) India ranks 3 th in egg and 5 th in broiler production in world. Fundamental genetic principles like linkage, epistasis etc. Attenuation method for live vaccines (Louis Pasteur, 1880). First evidence for viral induced tumor (Rous, 1911, Nobel Prize, 1966). Reverse transcriptase- Isolated from ALV (Tamin & Baltimore, 1963; Nobel Prize, 1975). Oncogenes in virus are from host cells (Bishop & Harold Varmus; Nobel Prize 1989). Major two arms of immune response, the T and B cells were first discovered in chicken.

PCA of egg increased from 5 to 8 (2007 to 2012) ; National average: 58 The number of broilers and poultry meat production has declined in 2012-13 compared to 2007-08. These situations indicate the potential of poultry rearing in the UP but warrants a proactive approach and policies to support poultry production
Development of Commercial Layer The chickens developed and reared for egg production are termed as layer. worldwide, layers are bred for higher Nos. of eggs/ kg of feed with sound shell strength, uniform shell colour without blood and meat spots and a reasonably upright egg white. Selection strategies to improve egg production include part-time egg production records, persistency of lay, clutch length, FCR/ Residual feed consumption(rfc) Skeletal problems (majorly osteomalacia and osteoporosis)

Management of commercial Layers Housing: Access to road service Level of the ground should be high The place should be dry. Future expansion needs Drainage Exposure of the house Wind direction Distance between houses
Basic Principles for Layout Design Layout should not allow visitors and outside vehicles to come in contact with birds. Administrative block and feed mill unit should be kept away from sheds Younger birds should be kept away from disturbances due to movements. The houses of should be necessarily placed on the upwind flow side to avoid cross-infection from adults to younger through air. In our country for major part of year, west is the upwind flow side. Feed mill is generally attached to medium and large size poultry farms and preferably placed near gate. Ventilation Ventilation keeps the atmosphere healthy in house Free flowing air in the house; Reduce the temp. inside house in summer Humidity (Optimum Humidity: 38 42 %) Higher humidity: Conducive for multiplication of pathogenis; Low Humidity: Dusty and dry litter
Layout of the poultry farm A Distance between 1 st house and approach road (20 m) B-Distance between incinerator and last house (30 m) D- Distance between two houses (10m) FM Feed mill I Incinerator S.O. Store and Office
Orientation of Poultry Houses In hotter parts of country, the long axis of the house should be east to westand the sides should face north south to prevent direct sun shine The areas where both the condition prevailed, long axis in the direction of Northeast to Southwestmay be helpful The wind direction and drainage should be from the houses of young stock to adult stock to aid in disease prevention. The distance between the houses of young and adult stock should be about 150-300 feet to help in disease prevention. Construction of Poultry Houses Foundation: 6-12 above the floor level for deep litter hosuses Floor: moisture proof, free from cracks, easily cleaned, rat proof and durable Sides and walls: 8 to 10 feet from floor level; 2/3 fitted with wire mesh; cold weather, curtains can be lowered from the overhang Roofs: draft and moisture proof; Asbestos or cement board roofs more desirable Laying cages: Ventilation: 50 exhaust fans on side of walls can be fitted for ventilation

Heating Devices: Several type of heating devices viz. electric bulbs including infra-red bulbs, gas brooder, electric heat convector, coal burning small sized furnace, saw dust stoves, oil burning stoves, hot water and hot air devices etc. The heating devices should be made available: to provide a temperature around 35 C in brooding area. Temperature in the rest of the pen can be allowed to drop to 20 or 15 C. For small flocks of up to 75 chicks, only a heat lamp may be required.

Feeders Feed is usually put in shallow boxes or egg flats on the floor or cage bottom for 4 to 6 days as well. Tubular type of feeders are used. On an average 4 tubular feeders (small size) /100 3 weeks onwards, larger size feeders (4); Feed should be offered frequently. Waterers-Good water is important. Sufficient number of waterersshould be provided to ensure adequate supply of fresh drinking water to all the chicks all the time. Non availability of adequate water is more hazardous for the growth of the bird and also reduces the feed intake. Fountain type waterer(2-3/ 100 chicks) may be provided from 0-2 weeks; afterwards small sized tub with grill may be used for watering.
Circular Drinker Fountain Type Drinker Automatic drinker Bell Shaped drinker
Nipple Drinker system
Fountain type waterer made of plastic or iron sheet. consisted of a cylindrical water container and a circular dish. The water container can sit loosely inside the circular dish with about 2.5 cm space remaining on all sides. Preferably, the top of water container is made conical so that chicks can sit over it and spoil water or topple it down. A hole is made in water container to push the water by air pressure. The water container filled with water is inverted over the dish; due to air pressure water is filled in dish. The chicks can easily drink water and accidental deaths due to drowning are also avoided. In large flocks, some form of automatic water system is usually installed. In a float controlled trough, 2 cm per bird is considered sufficient. One hanging fountain per 80 to 100 birds, one smaller cup per 50 birds, one nipple for 10-12 birds, will generally be adequate. In Circle brooding the feed and water should be placed at the edge of the heat reflectors, which is 60 to 70 cm above the floor.
Chick Feeder Automatic feeder
Grower Feeder
Feed Storage bins: Large size plastic or metallic drums having capacity of 200 L may be used for feed storage. The feed should not be stored for a long period as it may lead to growth of moulds and fungus. At the most feed for 4-5 days may be store. Feedshouldbeasfreshaspossible.
Equipment for Grower management: The watererand feeders are of larger size than that used during brooding stage. The round hanging feeders with capacity of 8-10 Kg capacity may also be used during growing stage. The water channels or automatic watering system may be used for supplying water during growing stage. In summers; the cooling devices like water sprinklers, foggers, coolers, fans etc are also used. Besides, on sides of grower houses the trees can be planted to keep the environment cool. High qualityfoggers, which are used by poultry farmers during the summers for bringing down the temperature by 8-10 Celsius.

Light regime Two basic Principles: 1. Never Increase the duration or intensity of light during the growing period. 2. Never Decrease the duration or intensity of light during the production period. 21-23 hrs of continuous light at one and two days of age and thenreducedto15or16hrsoflightuntilthe3weeksofage. At3-weeksofage,reducethehoursoflighttoabout12hoursor as dictated by natural day length. When target body weights are achieved start your stimulatory lighting program to increase 13 hours and then add 15-30 min perweekuntil16hrsoflightisreached. Light stimulation should continue until peak production One bulb of 30 watt is sufficient for an area of 100 sq. feet, if hanged 8 above floor.
The sensitivity of the young pullet to an increase in photoperiod varies with age and is at a maximum between 9 and 12 weeks of age and thus increasing the photoperiod at orsoonafter18weekshaslittleeffectonageat50%lay. Therefore, the use of step-down - step-up lighting programs should be timed to bring the birds into lay at the age. With early lay you will get more, smaller eggs and with late lay you willgetfewer,largereggs,butthetotaleggmassattheendof lay will not be much different.
Recommendations: A. R & D activities; B. Govt Policies Strengthening the efforts for development of poultry Germplasmat institutes/ SAUs/KVKs Least cost feed formulation using locally available ingredients. Strengthening the veterinary health services to reduce mortality. Training to poultry rearers on processing, trading etc Promoting integration of poultry with other farming activities. Diversified poultry production may be promoted. B: Govt policies: Financial assistance for poultry farming and allied sectors Strengthening infrastructure facilities and market network for expansion of poultry sector.
