🐖 Pig Breeds - Indigenous (Ghungroo, Ankamali) and Exotic (Yorkshire, Landrace, Duroc, Hampshire)
Complete guide to indigenous and exotic pig breeds including Large White Yorkshire, Landrace, Duroc, Hampshire, Tamworth, Ghungroo, Ankamali, breed selection criteria, gilt selection (12 teats), and culling norms for IBPS AFO and NABARD exams.
Selection of Breeds
Choosing the right breed is the foundation of a profitable pig farming enterprise. The selection depends on factors such as the purpose of rearing (meat, bacon, or lard), local climate, disease resistance, and market demand.
-
For commercial pig farming upgraded/crossbred or exotic stock in good health should be selected. Crossbred and exotic breeds tend to have higher growth rates, better feed conversion efficiency, and superior carcass quality compared to indigenous breeds under intensive management systems.
-
While selecting a gilt or sow primary aim should be to secure a female that will produce large survivable litter and which can attain marketable weight at an age of six months or less. A good gilt (young female pig that has not yet farrowed) should have at least 12 well-spaced, functional teats to ensure adequate milk supply for the litter.
-
Animals those are ready to be bred should be selected. Pig gestation period = 114 days (approximately 3 months, 3 weeks, 3 days — the "3-3-3 rule"). This is one of the most exam-tested facts in piggery management.

Selection of Breeds
Choosing the right breed is the foundation of a profitable pig farming enterprise. The selection depends on factors such as the purpose of rearing (meat, bacon, or lard), local climate, disease resistance, and market demand.
-
For commercial pig farming upgraded/crossbred or exotic stock in good health should be selected. Crossbred and exotic breeds tend to have higher growth rates, better feed conversion efficiency, and superior carcass quality compared to indigenous breeds under intensive management systems.
-
While selecting a gilt or sow primary aim should be to secure a female that will produce large survivable litter and which can attain marketable weight at an age of six months or less. A good gilt (young female pig that has not yet farrowed) should have at least 12 well-spaced, functional teats to ensure adequate milk supply for the litter.
-
Animals those are ready to be bred should be selected. Pig gestation period = 114 days (approximately 3 months, 3 weeks, 3 days — the "3-3-3 rule"). This is one of the most exam-tested facts in piggery management.
-
Cull the old animals after 10-12 farrowing. Culling at this stage is recommended because reproductive performance, including litter size and piglet survival rate, typically declines after 10-12 farrowing cycles.
-
Identify the newly purchased animal by giving suitable identification mark (ear notching or tattooing). Ear notching involves making specific cuts on the pig's ears following a standardised numbering system, while tattooing uses indelible ink stamped inside the ear. Both methods are permanent and essential for maintaining accurate breeding and health records.
-
Always vaccinate the animals against diseases. A proper vaccination schedule protects the herd against common swine diseases such as Classical Swine Fever (CSF), Foot and Mouth Disease (FMD), and Porcine Parvovirus (PPV).
TIP
For competitive exams, remember that a gilt should have at least 12 teats and culling is recommended after 10-12 farrowings.
Exotic Breeds
Exotic breeds (also called improved breeds) have been developed through selective breeding programmes in Western countries. They are known for their superior growth rate, feed efficiency, and carcass quality. The following are the major exotic breeds:
1. Large White Yorkshire (LWY)
- Origin: England (UK) — Yorkshire county
- Most extensively used exotic breed in India and an excellent breed for crossbreeding.
- Colour: White with erect ears (key identifier — distinguishes from Landrace's drooping ears).
- Body weight: Boar: 300-400 kg, Sow: 230-320 kg
- Prolific breeder with excellent mothering ability — large litter size of 10–12 piglets.
- Considered both a bacon type and pork type breed — versatile.
- Also grouped with Chester White breed.
TIP
Exam identifier for LWY: White colour + erect ears + English origin + most popular in India. Average litter size 10–12. Often called the "world's most popular pig breed."
2. Middle White Yorkshire
- Evolved by crossing the Large White Yorkshire with a smaller breed of Yorkshire extraction.
- Body weight: Boar: 250-340 kg, Sow: 180-270 kg
- Also grouped with Tamworth breed.
3. Landrace
- Origin: Denmark
- The best bacon breed in the world — bred and fed to produce the highest quality bacon (specifically Wiltshire bacon).
- Colour: White with long body and drooping/lop ears — the long body produces more bacon rashers per carcass.
- Body weight: Boar: 270-360 kg, Sow: 225–260 kg
- Litter size: 10–14 piglets — highly prolific, among the best for maternal traits.
- Also grouped with Berkshire breed.
- Excellent for crossbreeding programmes in India.
TIP
Exam identifier for Landrace: White + drooping ears (NOT erect like LWY) + Danish origin + best bacon breed (Wiltshire bacon). Long body = more rashers. Litter size 10–14.
4. Duroc
- Origin: USA
- Colour: Reddish-brown (cherry red / rust) coat — the only major red-coloured exotic breed.
- Ear type: Slightly drooping/pendulous ears (unlike the erect ears of LWY and Berkshire).
- Known for hardiness, fast growth rate, and good feed efficiency.
- Excellent muscling and best meat quality with marbling — favoured as a terminal sire for pork production.
- Docile temperament — easier to manage than many other breeds.
- Classified as a pork/meat type breed.
TIP
Exam identifier for Duroc: Red/rust colour (unique among exotic breeds) + drooping ears + American origin. Best for meat quality/marbling. Used as terminal sire in commercial crosses.
5. Hampshire
- Origin: USA (developed in USA from English stock originally from Hampshire County, England)
- Colour: Black with a white belt around the shoulders and forelegs — the white belt is the defining visual feature.
- Ear type: Erect ears.
- Excellent for lean meat production with good muscling and good mothering ability.
- Popular as a terminal sire in crossbreeding programmes.
- Classified as a pork/meat type breed.
TIP
Exam identifier for Hampshire: Black body + white belt around shoulders/forelegs + erect ears + American origin. The "belted" pattern is unique — do not confuse with Saddleback (also belted but English origin).
6. Berkshire
- Origin: England (UK)
- Colour: Black with 6 white points — nose/snout, 4 feet, and tail tip. The dished (upturned) face is another distinctive feature.
- Ear type: Erect ears.
- Medium-sized, sturdy breed with good meat quality.
- Grouped with Landrace as a bacon-type breed.
TIP
Exam identifier for Berkshire: Black + 6 white points (snout, 4 feet, tail) + dished face + erect ears + English origin. "6 white points" is the classic exam MCQ clue.
6a. Pietrain
- Origin: Belgium (village of Pietrain in Wallonia)
- Colour: White with black spots — distinctive piebald/spotted pattern.
- Ear type: Erect ears.
- Extremely lean, heavily muscled breed — exhibits double-muscling particularly in the hindquarters.
- Stress-susceptible — prone to PSS (Porcine Stress Syndrome), also called Malignant Hyperthermia. Caused by a mutation in the RYR1 (ryanodine receptor) gene.
- PSS leads to pale, soft, exudative (PSE) meat under stress conditions — a major quality defect.
IMPORTANT
Pietrain exam facts: White with black spots + Belgian origin + double-muscled/very lean + prone to PSS (Porcine Stress Syndrome). PSS is caused by RYR1 gene mutation. Pietrain × Duroc crosses reduce stress susceptibility while maintaining leanness.
7. Tamworth
- Origin: England (UK)
- Colour: Golden-red/sandy coat.
- One of the oldest pig breeds, known for hardiness and foraging ability.
- Grouped with Middle White Yorkshire.
8. Poland China
- Origin: USA
- Colour: Black with white markings on face, feet, and tail.
- Large, heavy breed used for lard production.
- Spotted Poland China is a variant with spotted markings.
9. Chester White
- Origin: USA
- Colour: Solid white.
- Good mothering ability and prolific breeder.
- Grouped with Large White Yorkshire.
10. Saddleback
- Origin: England (UK)
- Colour: Black with a white band (saddle) across the shoulders.
- Hardy breed suitable for outdoor/extensive systems.
IMPORTANT
Breed groupings for exams: Large White Yorkshire = Chester White | Middle White Yorkshire = Tamworth | Landrace = Berkshire. Duroc and Hampshire are American breeds (not European). This is a common exam trap.
MCQ Identification Table — Ear Type, Colour & Origin
This table is the single most useful reference for breed-identification MCQs in IBPS AFO / NABARD exams:
| Breed | Ear Type | Colour | Origin | Key Distinguisher |
|---|---|---|---|---|
| Large White Yorkshire | Erect | White | England | Most popular in India; large litter |
| Landrace | Drooping/Lop | White | Denmark | Long body; best bacon (Wiltshire) |
| Duroc | Drooping | Red/Rust | USA | Only red exotic breed; best marbling |
| Hampshire | Erect | Black + white belt | USA | Belt around shoulders & forelegs |
| Berkshire | Erect | Black + 6 white points | England | Dished face; snout+4 feet+tail |
| Pietrain | Erect | White + black spots | Belgium | Double-muscled; PSS susceptible |
| Poland China | Drooping | Black + white marks | USA | Lard type; large, heavy |
| Chester White | Drooping | Solid white | USA | Grouped with LWY |
| Tamworth | Erect | Golden-red | England | Oldest English breed; outdoor hardy |
| Saddleback | — | Black + white saddle | England | Similar to Hampshire but English |
TIP
Ear type memory trick:
- Drooping ears = Landrace, Duroc, Poland China, Chester White
- Erect ears = LWY, Hampshire, Berkshire, Pietrain, Tamworth, Middle White Yorkshire
- Colour trick: The only red exotic breed is Duroc. The only spotted breed is Pietrain. "Belt" pattern = Hampshire (USA) or Saddleback (UK).
These breeds are frequently crossed with indigenous breeds to combine the productivity of exotic germplasm with the disease resistance and adaptability of local stock.

Indigenous Breeds
Indigenous breeds of pigs in India are well adapted to local climatic conditions and can thrive on minimal inputs. While their growth rate and carcass quality are generally lower than exotic breeds, they offer advantages in terms of disease resistance, heat tolerance, and ability to survive on kitchen waste and agricultural by-products. India has 15+ NBAGR-registered indigenous pig breeds (as of 2024):
1. Ghungroo
- Home tract: West Bengal (Jalpaiguri, Cooch Behar, Darjeeling districts) and also found in Assam.
- Known for highest prolificacy among Indian breeds with litters of 8-12 piglets.
- Black coat, wrinkled skin, heavy pendulous ears — distinctive appearance.
- Compact body with good adaptation to North-East India's humid subtropical conditions.
- Excellent mothering ability and disease resistance.
- Most widely studied and documented indigenous breed; NBAGR-registered.
NOTE
Ghungroo is the most exam-important indigenous pig breed — remember: black + wrinkled skin + heavy pendulous ears + West Bengal/NE India + highest prolificacy among Indian breeds.
2. Niang Megha
- Home tract: Meghalaya
- Adapted to the hilly terrain and humid climate of the Khasi and Jaintia hills.
- Reared by tribal communities as an integral part of their socio-cultural life.
- Black or black-and-white coat colour.
3. Doom
- Home tract: Assam (Upper Brahmaputra valley)
- Small-sized breed with black coat.
- Well-adapted to the hot and humid climate of the Brahmaputra valley.
- Reared primarily by tribal communities in a free-range system.
4. Agonda Goan
- Home tract: Goa
- Named after the Agonda village in South Goa.
- Medium-sized with black coat.
- Adapted to the coastal tropical climate.
5. Tenyi Vo
- Home tract: Nagaland
- Reared by the Angami Naga tribe.
- Compact body with black coat.
- Important for the socio-economic life of tribal communities in Nagaland.
6. Zovawk
- Home tract: Mizoram
- Small to medium-sized, mostly black.
- Hardy breed adapted to hilly terrain.
- Name means "Mizo pig" (Zo = Mizo people; vawk = pig) in the local Mizo language.
7. Mali
- Home tract: Tripura (Dhalai and North districts) — NBAGR-registered
- Small-sized indigenous breed.
- Adapted to the humid sub-tropical conditions of Tripura.
8. Ankamali
- Home tract: Ankamali, Ernakulam district, Kerala
- Indigenous meat breed; black or black-and-white coat, medium-sized.
- Hardy breed well-adapted to Kerala's humid tropical conditions.
- Primarily reared in backyard systems by local farming communities.
- NBAGR-registered genetic resource.
9. Nicobari
- Home tract: Andaman and Nicobar Islands
- Small-sized, black coat; reared by indigenous tribes of the islands.
- NBAGR-registered genetic resource — important for exam awareness.
- Hardy and adapted to the island's tropical maritime climate.
NOTE
Most indigenous pig breeds in India are concentrated in the north-eastern states, where pork consumption and pig rearing are culturally significant. Ghungroo (West Bengal) is notable for its exceptionally high prolificacy. Ankamali (Kerala) and Nicobari (A&N Islands) represent important non-NE indigenous breeds.
Indigenous Breeds Quick Reference Table
| Breed | Home Tract (State) | Key Feature |
|---|---|---|
| Ghungroo | West Bengal | Highest prolificacy (8-12 piglets/litter) |
| Niang Megha | Meghalaya | Adapted to hilly terrain |
| Doom | Assam | Small, free-range system |
| Agonda Goan | Goa | Coastal tropical adaptation |
| Tenyi Vo | Nagaland | Reared by Angami Naga tribe |
| Zovawk | Mizoram | "Mizo pig" (Zo = Mizo people; vawk = pig) |
| Mali | Tripura (Dhalai & North districts) | NBAGR-registered; humid sub-tropical |
| Ankamali | Kerala (Ernakulam district) | Black/black-white; backyard, humid-adapted |
| Nicobari | Andaman & Nicobar Islands | Small, black; reared by indigenous tribes |
Desi vs Exotic Comparison
| Parameter | Desi | Exotic |
|---|---|---|
| Litter size at birth | 7.5 | 10 |
| Birth weight (kg) | 0.91 | 1.4 |
| Dressing percentage | 66% | 68% |
| Maturity (months) | 14 | 8-10 |
| Weaning weight (kg) | 4.1 | 13.5 |
| Weaning percentage | 54% | 78.5% |
TIP
Exam tip: Exotic breeds mature faster (8-10 months vs 14 months), have higher birth weight (1.4 vs 0.91 kg), and better weaning percentage (78.5% vs 54%) compared to desi breeds.
Litter Size Norms
Litter size is a key measure of sow productivity and varies significantly by breed:
| Breed / Category | Litter Size (piglets/litter) |
|---|---|
| Large White Yorkshire (LWY) | 10–12 |
| Landrace | 10–12 |
| Ghungroo | 8–12 (highest among Indian breeds) |
| Native / backyard breeds | 6–8 |
TIP
LWY and Landrace are the most prolific exotic breeds (10–12 piglets/litter). Ghungroo matches this range, making it the most prolific indigenous breed in India.
Breed Classification by Purpose
Understanding why each breed is used for specific products helps answer "best breed for ___" type MCQs:
| Purpose Type | Definition | Key Breeds |
|---|---|---|
| Bacon type | Long body, well-muscled, moderate fat — ideal for curing/slicing into rashers | Landrace (best), LWY |
| Pork/Meat type | Fast growth, high lean meat percentage, good dressing % | Duroc, Hampshire, Berkshire |
| Lard type | Heavy fat deposition — older/heritage breeds | Poland China, older Berkshire lines |
| Dual purpose | Both bacon and pork acceptable quality | Large White Yorkshire |
IMPORTANT
Key rule for exams:
- Landrace = best bacon breed (long body = more rashers; Danish = Wiltshire bacon tradition)
- Duroc = best meat quality (marbling, muscle conformation)
- Poland China = lard type (heavy fat, older breed)
- LWY = most prolific + versatile (bacon + pork + best mother)
Why does Landrace produce the best bacon? The long body of Landrace means more vertebrae (6–7 more than average breeds), which translates to a longer loin and more bacon rashers per carcass. The breed was specifically developed in Denmark through selective breeding focused on this carcass trait.
Crossbreeding in India
Crossbreeding between exotic and indigenous breeds is the most practical approach for improving pig productivity in India. The goals are to combine:
- Exotic traits: Higher growth rate, better FCR, superior carcass quality
- Indigenous traits: Disease resistance, heat tolerance, ability to thrive on low-cost feeds
Common crossbreeding combinations in India:
- Large White Yorkshire x Ghungroo — most popular cross in eastern India
- Landrace x indigenous breeds — for improved bacon-type pigs
- Hampshire x local breeds — for improved lean meat production
Advanced Crossbreeding Strategies (Exam-level)
NOTE
F1 crosses commonly used in pig production:
- LWY × Landrace — combines best prolificacy (LWY) with best bacon body (Landrace); F1 females are excellent mothers
- LWY × Duroc — combines high litter size with excellent meat quality
- Landrace × Duroc — European commercial standard for premium pork
IMPORTANT
Terminal sire system: In commercial pig production, F1 crossbred females (e.g., LWY × Landrace) are mated with a terminal sire — typically Duroc or Hampshire — to produce all-market pigs. The terminal sire contributes meat quality genes; no replacement gilts are kept from this cross.
Heterosis (hybrid vigour) in pigs: Crossbreeding exploits heterosis. The traits with the greatest heterosis effect in pigs are:
- Litter size — 5–10% improvement in F1 vs purebred average
- Piglet survival / weaning weight
- Growth rate — moderate heterosis (~5%) Carcass traits show the least heterosis — they are largely additive.
IMPORTANT
For IBPS AFO exams, remember that Large White Yorkshire is the most extensively used exotic breed in India for crossbreeding purposes.
