    Breeding and Reproduction Management By Big Pig Market — Updated 2025 Pig breeding is the foundation of every successful swine enterprise. Whether you run a backyard herd or a large commercial unit, understanding how pigs reproduce, mate, and farrow determines your productivity and long-term profit. Breeding management combines science, observation, and animal-care skill to ensure that each sow produces healthy litters at regular intervals and that every boar remains fertile and active. 1. Introduction to Pig Breeding In modern pig production, breeding is more than pairing males and females. It is a structured process that includes selecting superior parents, planning mating schedules, managing pregnancy, and caring for piglets after birth. Efficient breeding shortens the farrowing interval, increases litter size, and improves feed-to-meat conversion ratios. Average well-managed sows can farrow 2.3 litters per year with 9 – 12 piglets each. Proper heat detectio...

PIG BREEDS

 Most common Pig Breeds in Kenya

In Kenya, several pig breeds are commonly raised for commercial and subsistence farming. These breeds vary in terms of growth rate, reproductive performance, and adaptability to local conditions. The most common pig breeds in Kenya include:


1.Large White

-Characteristics: Large White pigs are one of the most popular breeds in Kenya due to their high reproductive performance, good growth rate, and excellent adaptability to various environments.

-Purpose: Primarily used for breeding due to their good maternal traits, they are often crossed with other breeds to improve productivity.


2.Landrace

-Characteristics: The Landrace breed is known for its ability to produce large litters and its excellent mothering abilities.

-Purpose: Similar to the Large White, Landrace pigs are often used for breeding purposes. They are known for their docile nature and good adaptability.


3.Pietrain

-Characteristics: Pietrain pigs are known for their lean meat production, fast growth rate, and high muscle development. They are typically white with black spots.

- Purpose: Pietrains are used for meat production due to their high yield of lean pork. However, they are not commonly kept as purebred but are often crossed with other breeds to improve meat quality.


4.Berkshire

- Characteristics: Berkshire pigs are black with white legs and have high-quality meat with marbling, which is highly sought after for premium pork products.

- Purpose: Primarily raised for high-quality pork production, though less common than other breeds in Kenya.


5.Mixed Breeds

   -Characteristics: Many farmers in Kenya use crossbreeding techniques to combine the best traits of different breeds, such as the Large White and Landrace or Large White and Pietrain.

   -Purpose: Crossbreeding is popular because it enhances growth rates, reproductive efficiency, and disease resistance, creating pigs that are well-suited for local conditions and market preferences.


         Local and Indigenous Breeds

Some indigenous pigs are also kept in Kenya, though they are less common compared to the aforementioned commercial breeds. These breeds tend to have lower productivity, but they are more hardy and adapted to local conditions.

      Pig Farming Considerations in Kenya

- Climate Adaptability: Some of these breeds, like the Large White and Landrace, are more adaptable to the Kenyan climate, while others like the Pietrain may require more controlled environments.

- Market Demand: The choice of breed often depends on market demand for meat quality, with leaner breeds like the Pietrain being preferred for commercial pork production.


Overall, Large White and Landrace breeds, often used for crossbreeding, dominate pig farming in Kenya due to their high productivity and ease of management.


The most common breeds in Kenya are the large white and the Land- race. The two breeds have good production characteristics like being prolific, fast growth rate and good mothering abilities. It is advisable for farmers to keep the two breeds or their crosses. Other breeds are Hampshire and Duroc pigs. 

I. LARGE WHITE Breed characteristics SOW 

- Have erect ears and dished face - Curved snout 

- Long body with excellent hams - Have fine white hair 

- Very prolific 

- Late maturing - Good mothering ability 

- Can be used for pork and bacon - Excellent breed for the purpose of cross breeding

 II. LANDRACE Breed characteristics Have white skin with black spots Have drooping ears (ear lopped) Have a straight and long snout Sow produce and rear large litter of pig- lets •Excellent for cross breeding.

II. HAMPSHIRE Breed characteristics Black with a white belt ency

- cling the fore quarter entirely. -Head is long and straight faced 

-Ears are straight and erect 

-Good mothering ability -Good for bacon 

-Have white fore legs and black hind legs? 

IV. DUROC Breed characterics Have golden brown to black colour with a thick auburn coat and hard skin. 

• Have small slightly drooping ears. 

• Associated with quick growth d) Crosses 

• Good for cross breeding 

Crosses


Crosses of different breeds exists e.g. Large white and Landrace. The crosses have good growth rate and carcass quality due to hybrid figure. 

BREEDING.                                                 2.1 SELECTION OF BREEDING PIGS 

(a) Selection of sows and gilts 

1.Select gilts from sows which have consistently farrowed and weaned large litters 

2. Choose gilts whose litter mates and other full sibs have given good performance in daily weight gain and feed conversion efficiency. Select gilts/sows that have at least 

12 functional teats to accommodate large litter 3. 4. Select gilts from sows that wean large litters(9-10 piglets)

-Breeding gilts are selected at weaning -Select fast growing weaners 

-Selected gilts should have good body confirmation (strong/sound feet) b) Selection of breeding Boar 

-Good boar should be selected as the boar contributes half the quality of the pig herd. It is the father of the herd! The boar should have good body confirmation. The boar should have at least 12 well placed rudimentary teats. - Select the boar from other male piglets before castration i.e. at 4 weeks based on growth rate. Purchase boar from a breeder or a farm keeping good farm records. The records will provide adequate information on the pig performance 

- A good boar will weigh 90 kg in about 5-6 months. 

- The boar should have no physical deformities and should be in good health. 

BREEDING MANAGEMENT 

(a) Sexual maturity 

(i) Gilts/sows 

•  Age to breed gilts is 7-8 months Weight of gilts at breeding 100-120 kg The length of the oestrus cycle range between 18 -24days with an average of 21 days. The heat period lasts 3-5 days. Best time to breed: For gilts first day of heat For sows 

- Second day of heat Number of services per sow/gilts is 2 services at an interval of 12-14 hours Occurrence of heat after weaning 2-10 days 

- Gestation period 114 days Sows reproductive life is 4-5 years. 

(ii) Boars The boar should start serving at 8months of age. At the start the young boar should be allowed only two services per week (in the first two months). After wards it can manage six services per week. Allow 1 boar for every 10-15 Sows

•Boars should be housed separately to avoid fighting. The sow should be transferred to the boar pen for service and not the other way round. 

•Boar's reproductive life is 3-4 year 

⚫ Time to serve-optimum time to serve the sow is 36-43 hours after showing the first heat signs. It is advisable to allow the boar to serve the sow twice at an interval of 12 hours between the services. This increases chances of conception. 

(b) Heat signs .Restlessness and uneasiness. 

⚫Swelling and reddening of the vulva. .White clear mucus discharge. Reduced appetite. 

⚫Mounting other sows and being mounted by others. 

(c) Time to serve •Sow/gilt stand still when pressure is applied on her back. -The optimum time to serve the sow is 36-43 hours after showing the first heat signs. 

- It is advisable to allow the boar to serve the sow twice at an interval of 12 hours between the services. This increases chances of conception. 

- After mating if the sow does not come to heat in 21-42 days, it confirms conception. 

(d) Gestation period: -Length of gestation is 114-117 days (3months 3weeks 3days) 

(e) Signs of farrowing

The following are the signs of approaching farrowing in sows and gilts: 

(i) Abnormal contractions -This appear 1 to 3 hours before birth (but can also occur just 15 minutes to up to 10 hours before birth. 

(ii) Nest (bed) making - Occurs about 24 hours before the birth of the first piglet. 

(iii) A lot of restlessness. 

(iv) Discharge of blood stained fluids. 

(v) Twitching of the tail. This begins about 2 hours before the first piglet is born. 

(vi) Presence of milk in the udder.

🐖 Importance of Choosing the Right Pig Breed

Selecting the right breed is one of the most critical decisions in pig farming. It directly impacts:

  • Profitability: Fast-growing breeds reduce feed costs and time to market.
  • Meat Quality: Some breeds produce leaner, high-marbling pork suited for premium markets.
  • Adaptability: Breeds that tolerate heat, local feed, and common diseases lower your operational risks.
  • Reproductive Performance: High-litter sows maximize your output per breeding cycle.

In Kenya, successful farmers often cross high-performance breeds like the Large White and Landrace to balance growth, fertility, and adaptability.
