🐔Poultry Breeds - White Leghorn, RIR, Plymouth Rock, Kadaknath and Indian Hybrids

Complete guide to poultry breeds covering egg-type (White Leghorn), meat-type (Cornish, Brahma), dual-purpose (RIR, Plymouth Rock), Indian breeds (Kadaknath, Aseel, Busra), and commercial hybrids (BV-300, Vanaraja, Gramapriya) for IBPS AFO and NABARD exams.

👉🏻 A breed denotes an established group of bird having the same general bony shape, weight and some common characteristics. Understanding poultry breeds is essential for selecting the right birds for a specific production goal, whether that is egg production (layers), meat production (broilers), or dual-purpose farming.


Classification

Poultry breeds are broadly classified based on their origin (American, English, Mediterranean, Asiatic) and their utility (egg-type, meat-type, or dual-purpose). This classification helps farmers make informed decisions when setting up their poultry enterprises.

NOTE

Class-wise Breed Overview (Exam Summary)

  • American class — Rhode Island Red (best dual-purpose, brown eggs), Plymouth Rock (dual-purpose, barred plumage), New Hampshire (meat-type, fast-growing)
  • Mediterranean class — White Leghorn (best layer, 280–300 eggs/yr, white eggs), Ancona (white eggs), Minorca (largest Mediterranean breed)
  • English class — Australorp (holds world egg record: 364 eggs in 365 days), Sussex (dual-purpose), Orpington (known for broodiness — tendency to sit on eggs)
  • Asiatic class — Brahma (heaviest breed, called “King of Poultry”), Cochin (feathered legs, very broody), Langshan (tall, upright), Chittagong (Bangladesh)
  • Indigenous Indian — Kadaknath (black meat, MP), Aseel (game/fighter), Busra (Maharashtra), Ghagus (Maharashtra)

Important Breeds

Leghorn

  • White Leghorn chickens are a variety of the Leghorn breed. They are known for their white feathers, bright red combs, and white earlobes.
  • Originating in Tuscany, in central Italy. The breed was later refined in the United States and Britain to become the world’s premier commercial egg-laying breed.
  • White Leghorns are commonly used as layer chickens in many countries of the world.
  • Leghorns are good layers of white eggs, laying an average of 280 per year and sometimes reaching 300-320, with a weight of at least 55 g. This exceptional egg production rate makes the Leghorn the gold standard for commercial layer operations.
  • Therefore, known as the best layer breed.
  • White Leghorns have been much used to create highly productive egg-laying hybrids for commercial and industrial operations. These hybrids combine the high egg output of the Leghorn with improved disease resistance and adaptability from other breeds.

TIP

Why does Leghorn lay white eggs? Egg shell colour is determined by genetics. White Leghorn hens have white earlobes, which is a reliable indicator of white egg-laying in chickens. The shell lacks the protoporphyrin pigment that produces brown colouration. In contrast, breeds like Rhode Island Red have red earlobes and deposit protoporphyrin pigment on the shell during the final stage of egg formation, producing brown eggs. This is a common MCQ: White earlobe = white eggs; Red earlobe = brown eggs.


Rhode Island Red

  • The Rhode Island Red is an American breed of domestic chicken. It is the state bird of Rhode Island. Note that it is not an English breed; it was developed in the US states of Rhode Island and Massachusetts.
  • The color of the plumage of the traditional Rhode Island Red ranges from a lustrous deep red to almost black; the tail is mostly black.
  • The traditional dual-purpose Rhode Island Red lays 200-300 brown eggs per year, and yields rich-flavored meat. (Best Dual Purpose Breed). Being dual-purpose means the breed is economically viable for both egg and meat production, making it ideal for small-scale and backyard farming.

Plymouth Rock

  • The Plymouth Rock is an American breed of domestic chicken.
  • It has barred plumage pattern on body. The distinctive barred pattern consists of alternating stripes of dark and light feathers, giving the bird a striking appearance.
  • The Plymouth Rock is a dual-purpose breed and is kept both for its meat and for its large brown eggs, of which it lays 200–250 eggs/year (Barred Plymouth Rock). The eggs weigh about 55 g.
  • Dual-purpose American breed; historically significant as foundational stock for modern broiler industry; now replaced by Cornish Cross hybrids for commercial broiler production.

Kadaknath

  • Indian breed of chicken originated from Dhar and Jhabua districts of Madhya Pradesh.
  • Kadaknath birds are grey-black all over and have gold plumage with greenish iridescence. The greyish black colour is present in the legs and toenails, beak, tongue, comb and wattles; even the meat, bones, blood and organs have black colouration. This phenomenon of black pigmentation throughout the entire body is called fibromelanosis.
  • Egg colour is light brown/pinkish (the bird itself is black due to fibromelanosis, but eggs are light brown/pinkish — not black).
  • Also known as Kali Masi (Fowl having black flesh).
  • Egg production: 80–140 eggs/year (backyard conditions ~80; managed conditions ~120–140).
  • Meat contains very less fat % which is just 0.73–1.03% compared to other chicken which is 13–25% (per PMC research). This extremely low fat content makes Kadaknath meat highly sought after by health-conscious consumers and is one of the reasons it commands a premium price in the market.
  • Black colour due to melanin pigment. Melanin is a natural pigment responsible for dark colouration in skin, feathers, and internal organs of the Kadaknath breed. This phenomenon is called fibromelanosis.
  • Kadaknath chicken meat from Jhabua district of Madhya Pradesh has now got a Geographical Indication (GI) tag. A GI tag is an intellectual property right that certifies the product’s origin, quality, and reputation tied to a specific geographical location.
  • Due to the relatively high consumption of the breed, its numbers have sharply declined throughout the years. To save the breed from extinction, the state government started a Kadaknath poultry breeding program involving 500 families who are below the poverty line, who were to receive financial support and assistance. This conservation programme serves the dual purpose of protecting genetic diversity and providing livelihood support to economically weaker communities.

Aseel

  • Aseel is an Indian breed of game chicken. (fighting sports). The Aseel is one of the oldest known breeds of chicken in the world and has been bred in India for its fighting ability for centuries.
  • In Arabic, Aseel, means “high born” which coincides the temperament of the Aseel.
  • In India, the Aseel are bred for cock fights because of the aggressive nature.
  • It is found in Chhattisgarh, Orissa and Andhra Pradesh.
  • The Aseel has broad, prominent shoulders, wide hips; narrow stern, but “thick and strong in hand at root of tail,” which is an indication of strength. It has full, broad, heavily fleshed breast; thick and muscular thighs. This powerful body conformation reflects the breed’s selection for strength and stamina.
  • Indian game breed, heaviest native fighting breed; slow-growing; prized for meat quality and strength; not selected for rapid early weight gain.
  • Egg production: 40–70 eggs/year — one of the poorest layers among recognized breeds, as selection has been entirely for fighting ability and body conformation.
  • Notable for the longest leg spurs among Indian breeds — a direct consequence of selection for cockfighting; longer spurs confer advantage in combat.

IMPORTANT

Aseel MCQ Facts: Best fighter breed in India | Found in Chhattisgarh, Odisha, Andhra Pradesh | “Aseel” = “high born” in Arabic | Lays only 40–70 eggs/year (worst layer) | Longest leg spurs | Heaviest native fighting breed | Meat quality is excellent despite slow growth


Pratapdhan

  • The Pratapdhan is a dual-purpose chicken breed that was developed by the AICRP on Poultry Breeding at MAHARANA PRATAP UNIVERSITY OF AGRICULTURE & TECHNOLOGY, (MPUAT) in Udaipur, Rajasthan. The AICRP (All India Coordinated Research Project) on Poultry Breeding works on developing improved poultry varieties suited for rural and backyard farming conditions across India.
  • It was developed using the Mewari, Rhode Island Red, and colored broiler breeds. The Pratapdhan is similar to the local birds of Rajasthan. By combining genes from indigenous (Mewari) and improved (Rhode Island Red, coloured broiler) breeds, the Pratapdhan offers better productivity while retaining the hardiness of local stock.
  • Lays brown eggs that weigh around 52 g.
  • The Pratapdhan is well accepted by farmers in Rajasthan and nearby areas.

  • Breed form the Directorate of Poultry Research (ICAR), Hyderabad
    • Gramapriya
    • Sindhi
    • Krishibro
    • Vanashree
    • Vanaraja

These breeds have been developed by ICAR-Directorate of Poultry Research specifically for rural and backyard poultry farming, where birds need to be hardy, disease-resistant, and capable of thriving under low-input conditions.

Hybrid Breeds

  • Layer: Babcock 300, Hyline-WS 36, Bovans. These commercial layer hybrids are the result of sophisticated crossbreeding programmes and are capable of producing over 300 eggs per year under optimal management.
  • Broiler: Ross, Vencobb, Hybro. These broiler hybrids have been bred for extremely rapid growth, reaching market weight of 2 kg or more in just 5-6 weeks. They are the most commonly used breeds in the commercial poultry meat industry worldwide.

IMPORTANT

Commercial Layer Strains — MCQ Details:

White egg layers (White Leghorn-based):

  • ISA White — widely used globally
  • Babcock B-380 — popular in India
  • Hy-Line W-36 — produces ~300–320 eggs/year

Brown egg layers (RIR/RIR-cross-based):

  • ISA Brown — most popular brown egg commercial layer worldwide
  • Lohmann Brown — 300–320 eggs/year; very efficient feed converter

Commercial layers produce 300–320 eggs per year under controlled environment housing.

IMPORTANT

Commercial Broiler Strains — MCQ Details:

  • Cobb 500 — most widely used broiler strain globally
  • Ross 308 — fast-growing, high breast meat yield
  • Hubbard Classic — good FCR and uniformity

Key performance parameters for commercial broilers:

  • FCR (Feed Conversion Ratio): 1.8–2.0 — i.e., 1.8–2.0 kg of feed required to produce 1 kg of live weight gain. Lower FCR = more efficient breed.
  • Slaughter age: 6–7 weeks at approximately 2 kg live body weight.
  • FCR is a critical economic parameter — broiler profitability depends heavily on achieving low FCR values.
