Introduction to Poultry Farming and Industry Scenario
Poultry covers chicken, duck, turkey, quail, guinea fowl and emu; chicken dominates Indian poultry output by volume and value.
Odisha poultry is dominated by backyard indigenous birds plus commercial broiler belts near Cuttack, Khordha, Bhubaneswar and Sambalpur.
Commercial poultry is a short-cycle enterprise: broiler flock turnover 5-6 weeks, layer cycle about 72-80 weeks, so cash flow is faster than most livestock.
Key performance indicators: feed conversion ratio (FCR), livability %, egg production per hen housed (EPHH), age at market weight, mortality %.
Backyard poultry contributes rural protein and cash income; improved dual-purpose birds raise egg and meat yield over desi birds.
Poultry converts feed to protein efficiently: broiler FCR near 1.5-1.7 under good management versus 3-4 for ruminant meat.
Vertical integration links hatchery, feed mill, grower and processor; contract farming shifts price risk from farmer to integrator.
Industry risks: disease outbreaks (especially avian influenza), feed price volatility (maize, soybean meal), and electricity or cold-chain gaps.
Poultry Breeds
Classify birds by purpose: layer (Leghorn, Rhode Island Red, Narmada, Kalinga), broiler (Cornish cross, Cobb, Ross, Vencobb), dual purpose (Kadaknath, Giriraja, Gramapriya).
Indigenous Odisha birds include desi non-descript, Hansli and other local types kept for hardiness, broodiness and scavenging ability.
Leghorn: Mediterranean class, light body, white or brown eggs, excellent layer, poor brooding instinct, nervous temperament.
Rhode Island Red: dual-purpose American class, brown eggs, heavier than Leghorn, good mothering, widely used in crossbred layers.
Cornish: heavy, broad-breasted, poor leg and reproductive fitness; used as male line in broiler crosses, not as a stand-alone farm bird.
Kadaknath: black plumage, black meat and dark eggs, native to Madhya Pradesh, marketed as premium niche meat.
Ducks: Khaki Campbell for eggs, White Pekin for meat; ducks need water for bathing but not for swimming to thrive.
Breeds differ in broodiness: heavy and indigenous birds go broody and stop laying; Leghorn-type layers rarely go broody.
Selection and Breeding
Selection criteria for layers: age at first egg, egg number to 72 weeks, egg weight, shell quality, feed efficiency, livability.
Selection criteria for broilers: body weight at 6 weeks, breast yield, FCR, leg soundness, livability.
Breeding systems: inbreeding (raises homozygosity, exposes lethals), line crossing, outcrossing, and three- or four-way terminal crosses for broilers.
Heterosis (hybrid vigour) is the gain from crossing; commercial broiler and layer stocks are hybrids, so their progeny do not breed true.
Sexing day-old chicks: vent sexing (Japanese method) for most breeds; feather sexing works only in slow-feathering female x fast-feathering male crosses.
Culling rules: remove birds with poor body condition, prolapse, lameness, persistent non-layers (dry, tight vent, pale comb) and deformed beaks.
Selection differential is the gap between selected parents and flock mean; response to selection equals heritability times selection differential.
Trap nesting identifies individual hen egg records, the basis for family and individual selection in layer breeding.
Housing, Equipment and Farm Layout
Floor space standards: broilers 0.09-0.11 sq m per bird; layers on deep litter about 0.16-0.20 sq m; cage systems reduce area per bird.
Brooder space: about 0.05 sq m per chick in first week, expanding as birds grow; feeder and drinker space scale with age.
Orientation: long axis east-west to limit direct sun on side walls; ridge ventilation at the roof apex to vent hot air.
Deep litter uses 5-8 cm of dry absorbent material (paddy husk, sawdust, wood shavings); litter moisture above 30% causes caking and ammonia.
Cage, deep litter and slatted floor are the three main systems; deep litter suits Odisha's humid climate if litter is kept dry.
Farm layout: separate chick, grower and layer houses, feed store, egg room and disposal pit; minimum 50-100 m between age groups for biosecurity.
Equipment: linear feeders, bell or nipple drinkers, brooders (gas, electric or charcoal), cages, egg trays and fumigation chamber.
Ventilation: birds need fresh air without draught; ammonia above 25 ppm and CO2 above 3000 ppm indicate poor ventilation.
Feeds, Feeding Standards and Nutrition
Feed is 65-75% of production cost; maize is the main energy source, soybean meal and fish meal are protein sources.
Crude protein norms: chick starter 20-22%, grower 16-18%, layer 16-18%, broiler starter 22-23%, broiler finisher 19-20%.
Metabolizable energy norms: broiler starter about 3000 kcal/kg, layer mash about 2600-2700 kcal/kg.
Calcium: layer feed 3.5-4.0% (limestone/oyster shell), broiler feed 0.9-1.0%; excess calcium in chick feed causes kidney damage and poor growth.
Essential amino acids to balance: methionine (first limiting), lysine, tryptophan; add synthetic methionine or lysine where plant proteins fall short.
Feed additives: vitamins A, D3, E, K, B-complex; trace minerals (zinc, manganese, iron, copper, selenium, iodine); salt 0.3-0.5%.
Water intake is roughly 1.6-2.0 times feed intake; a sudden water drop precedes a drop in feed intake and egg production.
Feed forms: mash, crumble (for chicks) and pellet (for broilers); pelleting improves intake and reduces feed wastage.
Incubation, Hatchery and Chick Management
Chicken incubation: 21 days; duck 28 days; turkey 28 days; quail 17-18 days.
Set-points for forced-draft incubator: temperature 37.5-37.8 C, relative humidity 55-60% during incubation, raised to 65-70% at hatching.
Turning: eggs turned every hour or at least 4-6 times daily through day 18, then stopped for hatch; turning prevents embryo sticking to shell membranes.
Candling: day 7 to remove infertile and early deads; day 18 to remove dead embryos before transfer to hatcher.
Hatchability norms: 80-85% of fertile eggs; fertility 90-95%; chick yield about 65-68% of egg weight.
Hatchery hygiene: fumigation with formaldehyde and potassium permanganate, eggs disinfected within 2 hours of lay, strict one-way flow from dirty to clean areas.
Chick quality: bright eyes, dry fluff, active, well-healed navel, no red hock; day-old chick weight about 38-42 g for broiler strains.
Sexing, vaccination (Marek's at hatchery) and grading are the final hatchery operations before dispatch.
Brooding and Rearing of Growers and Layers
Brooding temperature: 33-35 C in week 1, reduced 2-3 C weekly to about 24 C by week 5; behaviour of chicks indicates comfort.
Brooder guard: a circle about 1.5-2 m diameter for 100-200 chicks; expands as chicks grow to prevent crowding.
Chick comfort signs: spread evenly when warm; huddle under heat when cold; pant and move away when too hot.
Debeaking: layer pullets at 7-10 days and again at 10-12 weeks; broilers not usually debeaked.
Grower phase (5-18 weeks) controls body weight and uniformity; target uniformity above 80% within plus or minus 10% of mean weight.
Lighting: decreasing day length for growing pullets to delay sexual maturity; 14-16 hours light in lay, not increased during lay.
Point-of-lay: transfer pullets to layer house at 16-18 weeks, provide nest boxes, layer feed and calcium source before first egg.
Rearing on deep litter with perches supports skeletal development and reduces cannibalism and feather pecking.
Broiler Production and Management
Broiler cycle: 5-6 weeks to 2.0-2.5 kg live weight; target FCR 1.5-1.7; livability above 95%.
Pre-starter (0-14 days) and starter (15-21 days) crumbles, then finisher pellets; feed restriction is not advised in broilers.
Brooding temperature and ventilation are the two biggest determinants of early mortality; check crop fill 8-24 hours after placement.
Lighting programme: continuous or near-continuous light in early life, then 18-20 hours light with dark periods to reduce metabolic disorders.
Heat stress control: fans, foggers, cool drinking water, feeding in cool hours; heat stress raises mortality and reduces weight gain.
Common broiler problems: ascites, sudden death syndrome, leg weakness, wet litter and footpad dermatitis.
Weigh samples weekly to track growth against breed standard; adjust feed and ventilation before problems appear.
Withdrawal periods before slaughter: follow drug label, typically 5-7 days for common antibiotics; no medicated feed in final week unless specified.
Poultry Health, Disease Prevention and Biosecurity
Viral diseases: Newcastle disease (Ranikhet), infectious bursal disease (Gumboro), Marek's, fowl pox, avian influenza, infectious bronchitis.
Bacterial diseases: fowl cholera (Pasteurella), colibacillosis, salmonellosis, mycoplasmosis, necrotic enteritis (Clostridium).
Parasites: coccidiosis (Eimeria) controlled by coccidiostats or vaccination; external mites, lice and worms need routine checks.
Vaccination schedule: Marek's at day 1 hatchery; ND (F1/RDV) at day 7 and 28; IBD at day 14 and 21; fowl pox at 6-8 weeks; ND killed at 16-18 weeks.
Biosecurity layers: footbath at entry, restricted visitors, all-in all-out, rodent and wild bird control, disinfection between batches.
Post-mortem and lab confirmation are needed; do not treat blind, and record drug use with withdrawal periods.
Newcastle disease signs: gasping, greenish diarrhoea, twisted neck, drop in egg production, high mortality; report suspicion to veterinary authorities.
Water sanitation with chlorine or acidifiers reduces bacterial load; clean drinkers daily and test water quality periodically.
Poultry Products, Processing and Value Addition
Egg composition: about 58% albumen, 31% yolk, 11% shell; egg weight 55-65 g for commercial layers.
Egg quality: Haugh unit measures albumen height; yolk colour from carotenoids; shell strength falls with age and heat stress.
Egg storage: 13-15 C and 70-80% RH for short term; cold storage extends shelf life; washed eggs need refrigeration.
Meat processing: slaughter, bleeding, scalding (about 55-60 C), defeathering, evisceration, chilling, cutting and packaging.
Value addition: cut-up chicken, nuggets, sausages, marinated products, egg powder, pickled eggs, and poultry manure as organic fertiliser.
Cold chain: meat held at 0-4 C for chilled and below -18 C for frozen; temperature abuse causes spoilage and pathogen growth.
HACCP and FSSAI standards govern poultry processing; hygiene, potable water and worker health are critical control points.
By-products: feathers to meal, offal to pet food, litter and manure composted to organic fertiliser.
Farm Records, Economics and Marketing
Key records: daily egg or mortality count, feed consumed, body weight, medication, vaccination, sales and expenses.
Cost of production per bird = total flock cost / birds sold; per kg = total cost / total live or dressed weight.
Feed conversion ratio = feed consumed (kg) / weight gain or eggs produced; lower FCR means better efficiency.
Egg production % = eggs collected / hens alive x 100; hen-housed and hen-day rates differ because hen-day excludes mortality.
Break-even point: the price or output at which revenue equals total cost; compute for the batch before deciding expansion.
Marketing channels: local trader, wholesale market, contract integrator, direct retail and cooperative; each has different price risk.
Gross margin = gross income minus variable costs (chicks, feed, medicine, litter); fixed costs include shed, equipment and labour.
Record keeping supports loan applications, insurance claims and disease traceability; use a simple daily register plus monthly summary.
Entrepreneurship, Occupational Safety and Environmental Management
Enterprise planning: market survey, capital budget, working capital for one full cycle, and a break-even analysis before start-up.
Finance sources: bank loans under agriculture and allied schemes, NABARD refinance, state poultry missions and self-help group credit.
Risk management: batch insurance, contract farming, diversified products, and maintaining a reserve for disease or price shocks.
Occupational hazards: ammonia and dust cause respiratory disease; use masks, gloves and boots; disinfect wounds promptly.
Zoonoses: avian influenza, salmonellosis and psittacosis can pass to humans; hand hygiene and PPE reduce risk.
Environmental management: compost litter and manure, avoid runoff into water bodies, control odour and flies, and dispose of dead birds by deep burial or incineration.
Waste to value: poultry litter as organic fertiliser or biogas feedstock reduces disposal cost and adds income.
Regulatory compliance: FSSAI for products, pollution control norms for large farms, and veterinary drug residue limits in meat and eggs.
