🐔 Poultry Breeds
Complete guide to Indian and exotic poultry breeds — White Leghorn, Road Island Red, Cornish, Plymouth Rock, Aseel, Kadaknath and more for CUET Agriculture.
Introduction to Poultry
Poultry refers to all domesticated birds reared for eggs, meat, and feathers. The poultry industry is one of the fastest-growing sectors of Indian agriculture, providing affordable protein to millions.
- Scientific name: Gallus Domesticus
- Chromosome number: 2n = 78 — the highest chromosome number among all commonly studied livestock animals.
- Family: Gallinidae / Phasianidae
- Recognized breeds in India: 19
- Poultry includes: All domesticated birds reared for eggs and meat — chicken, duck (Batakh), goose (Kalahans), pigeon (Kabutar), turkey, quail (Bater). While chicken dominates commercially, each bird type has specific regional importance.
- Rajasthan: Ajmer district is the leading area for poultry and egg production in the state.
Egg Production Facts
| Parameter | Desi (Indigenous) | Videshi (Exotic) |
|---|---|---|
| Egg production | 120 eggs/year | 240–260 eggs/year |
| Hatching period | 21 days | 21 days (Turkey: 28 days) |
The dramatic difference between desi and exotic breeds — 120 vs 240-260 eggs/year — is why commercial poultry farming almost exclusively uses exotic breeds. However, desi breeds have better disease resistance and can survive on scavenging.

Egg Production Facts
| Parameter | Desi (Indigenous) | Videshi (Exotic) |
|---|---|---|
| Egg production | 120 eggs/year | 240–260 eggs/year |
| Hatching period | 21 days | 21 days (Turkey: 28 days) |
The dramatic difference between desi and exotic breeds — 120 vs 240-260 eggs/year — is why commercial poultry farming almost exclusively uses exotic breeds. However, desi breeds have better disease resistance and can survive on scavenging.
Egg Composition and Quality
- Egg shell: Mainly CaCO3 (94%) — calcium carbonate makes up almost the entire shell. This is why laying hens need a calcium-rich diet (usually supplemented with crushed oyster shells or limestone).
- Caloric value: ~80 calories per egg
- Egg color: Yellowish tint due to Xanthophyll pigment (Jesthophyll varnack) — this carotenoid pigment comes from the hen's feed (green plants, maize).
- Egg quality testing: Done by Candling (at 7 and 14 days of incubation) — candling involves shining a bright light through the egg in a dark room to check embryo development, detect cracks, and identify infertile eggs.
- Best storage period: February–March
- Infertile egg: Unfertilized egg (also called vegetarian egg) — eggs sold commercially are typically infertile as hens lay eggs without mating.
- Hen forms one egg: In approximately 24 hours
- Egg-laying hens: Do not require artificial light
NOTE
Candling is a non-destructive quality test. The name comes from the historical practice of using a candle flame as the light source. Modern hatcheries use electric candlers for efficiency.
Meat Production Facts
- Broiler birds: Ready for meat at 2 months (6–8 weeks) — broilers grow incredibly fast, reaching market weight in just 6-8 weeks due to selective breeding and optimized nutrition.
- White meat: Also called Safed Mans / Chicken — poultry meat is called "white meat" because it has less myoglobin (the protein that makes red meat dark) compared to beef or mutton.
- Layer birds: Start egg production at 5–6 months of age
- Caponization: Castration of male chicken (castrated male = Kapon/Capon) — caponized birds grow larger and produce more tender, flavorful meat.
Feeding and Nutrition
| Nutrient | Percentage in Feed |
|---|---|
| Carbohydrates | 70–80% |
| Protein | 10–20% |
| Fat | 2–5% |
| Minerals | 0.8–1.0% |
| Salt (NaCl) | Must be provided |
The high carbohydrate content (70-80%) provides the energy needed for rapid growth (broilers) or sustained egg production (layers). Protein is the second most important nutrient — essential for muscle growth in broilers and egg formation in layers.
Nutritional Deficiency Disorders
These are very frequently asked in exams — memorize each deficiency-disease pair:
| Deficiency | Disease / Condition |
|---|---|
| NaCl (Salt) | Cannibalism — pecking and eating each other. This is one of the most serious behavioral problems in poultry. |
| Vitamin A | Poor feathering (give green fodder, rijka, barseem to correct) |
| Vitamin E | Crazy Chick Disease (encephalomalacia) — causes neurological symptoms, loss of coordination, and head retraction in chicks. |
| Manganese (Mn) | Perosis (slipped tendon) — the hock joint swells and the tendon slips, causing leg deformity. |
| Zinc (Zn) | Parakeratosis (skin lesions) — causes thickening and crusting of the skin. |
WARNING
Salt deficiency causing cannibalism is the most commonly asked poultry nutrition question. When birds lack salt, they develop abnormal pecking behavior, attacking and consuming flesh of other birds. Ensuring adequate NaCl in feed is critical.
Other Important Facts
- Leucosis: Disease that spreads through eggs — a viral disease that can be transmitted vertically from hen to chick via the egg.
- Litter: Bedding material for chickens on the floor — made from sawdust, rice husk, or straw.
- Hen to Rooster ratio for egg production: 10:1 — for fertile egg production, one rooster is sufficient for 10 hens.
- Vitamin needs for feathers: Vitamin A and Resh (obtained from green fodder, rijka, barseem)
Important Developed Breeds
| Breed | Developed By | Features |
|---|---|---|
| PD-2 | CARI, Izatnagar (Bareilly) | Improved desi breed |
| Pratap Dhan | AICRP, MPUAT, Udaipur | Dual-purpose rural breed |
These are Indian-developed breeds designed to combine the disease resistance of desi breeds with the higher productivity of exotic breeds, making them suitable for rural backyard poultry farming.
Classification of Poultry Breeds
By Origin
| Desi (Indian) | Asiatic | English | American | Mediterranean | Polish |
|---|---|---|---|---|---|
| Aseel | Brahma | Red Cornish | Road Island Red | White Leghorn | Polish |
| Chatgav | Cochin | Sussex | Plymouth Mouth Rock | Ankona | |
| Kadaknath | Langshan | Australorp | Jacy Black Giant | Minarka | |
| Ghagas | Red Cap | New Hampshire | Baidot | ||
| Nakkal Nek | Orpington | ||||
| Busra | |||||
| Ankleshwar |
By Purpose
| Purpose | Breeds |
|---|---|
| Egg production (Layers) | White Leghorn, Minarka, Ankona |
| Meat production (Broilers) | Brahma, Sussex, Langshan, Aseel, Plymouth Mouth Rock |
| Dual-purpose | Dorking, New Hampshire, Road Island Red |
TIP
Memory trick for classification: Mediterranean breeds = best layers (White Leghorn leads). Asiatic and English breeds = best broilers (heavy, meaty bodies). American breeds = dual-purpose (RIR, New Hampshire).
Detailed Breed Descriptions
1. White Leghorn
| Feature | Detail |
|---|---|
| Origin | Italy (Mediterranean class) |
| Body | Small, active, alert |
| Color | White body with yellow beak and legs |
| Feathering | Clean feathered, legs are featherless |
| Comb | Single comb |
| Special features | Best egg-producing breed in the world, Mediterranean's best breed |
| Egg production | 240–260 eggs/year |
| Egg color | White |
White Leghorn is the world's best egg-producing breed, laying an impressive 240-260 eggs per year. It is the foundation of the global commercial egg industry. Its small, active body channels maximum energy into egg production rather than body growth. The white eggs with single comb and clean, featherless legs are identification features.
IMPORTANT
White Leghorn is the single most important poultry breed for exams. It appears in almost every livestock-related question paper.
2. Road Island Red (Rhode Island Red)
| Feature | Detail |
|---|---|
| Origin | America (American class) |
| Body | Large, rectangular |
| Developed from | Cross of Malay x Leghorn x Asiatic breeds |
| Body weight | Male: 3.8 kg, Female: 3.0 kg |
| Special features | Popular pet breed, hardy and adaptable |
| Egg production | 100–200 eggs/year |
| Egg color | Brown |
Road Island Red (RIR) is America's most famous dual-purpose breed. Its large, rectangular body makes it good for meat, while it also produces a respectable 100-200 brown eggs per year. It was developed from a complex cross of Malay, Leghorn, and Asiatic breeds, combining the best traits of each. RIR is one of the hardiest breeds — it can tolerate a wide range of climates and management conditions.
3. Red Cornish
| Feature | Detail |
|---|---|
| Origin | England (English class) |
| Developed from | Aseel x Malay x English breeds |
| Comb | Pea comb |
| Skin | Yellow |
| Chest | Wide |
| Special features | Famous for meat production, muscular and compact body |
The Red Cornish is one of the world's premier meat breeds. Its wide chest and compact, muscular body produce maximum breast meat. Interestingly, it was developed partly from the Indian Aseel breed, which contributed its muscular build and strong frame. The pea comb (three ridges on top of the head) is a distinctive identification feature.
4. Plymouth Mouth Rock (Plymouth Rock)
| Feature | Detail |
|---|---|
| Origin | America (American class) |
| Body | Large |
| Special features | Good for both meat and eggs, popular broiler breed (Broiler hetu prashid), barred feather pattern |
Plymouth Rock is a versatile American breed with a distinctive barred (striped) feather pattern — alternating dark and light bands on each feather. It is widely used as a broiler parent breed because of its large body and rapid growth rate.
Important Indian Breeds
Aseel
- Classification: Desi / Indian breed
- Purpose: Meat and fighting (game bird)
- Features: Muscular body, aggressive temperament, very poor egg production, strong legs
- Historical significance: One of the oldest known chicken breeds in the world — Aseel has been bred in India for thousands of years, originally for cock fighting. Its name means "pure" or "of long pedigree" in Arabic.
Kadaknath
- Classification: Desi / Indian breed
- Origin: Madhya Pradesh (Jhabua, Dhar districts)
- Features: Black feathers, black meat, black bones — completely melanistic breed
- Special: High protein, low fat meat — considered medicinal in tribal communities. The black coloration is caused by fibromelanosis, a genetic condition that causes excessive pigmentation of all tissues.
Why is Kadaknath meat considered special?
Kadaknath is a **completely melanistic breed** — its feathers, skin, meat, bones, and even internal organs are black. This is caused by a genetic condition called **fibromelanosis**. The meat contains: - **Higher protein** (25-27%) compared to regular chicken (18-20%) - **Lower fat** and **lower cholesterol** - **Higher iron content** - **Melanin** — which is believed to have antioxidant propertiesKadaknath meat commands a premium price (3-5 times regular chicken) and has received a GI tag for Jhabua district, MP.
