Understanding Pig Nutritional Requirements in Kenya
Before diving into formulations, it’s essential to understand what pigs need at different life stages.
Weaner Pig Nutritional Needs (3-8 weeks)
Weaner pigs have the highest nutritional demands due to rapid growth:
- Crude Protein: 20-24%
- Metabolizable Energy: 12.5-14.0 MJ/kg (3,000-3,345 kcal/kg)
- Lysine: 1.15-1.35%
- Calcium: 0.8-0.9%
- Phosphorus: 0.6-0.7%
Sow Nutritional Requirements
Sows have different needs depending on their reproductive stage:
Gestating (Pregnant) Sows:
- Crude Protein: 13-15%
- Metabolizable Energy: 12.5-13.0 MJ/kg
- Feed amount: 2.0-2.5 kg per day
Lactating (Nursing) Sows:
- Crude Protein: 15-18%
- Metabolizable Energy: 12.5-13.5 MJ/kg
- Feed amount: 4.0-7.0 kg per day

Feeding Guidelines for Sows
Gestating (Pregnant) Sows:
- Feed amount: 2.0-2.5 kg per day
- Feeding times: 2 times daily (morning & evening)
- Last 2 weeks before farrowing: Increase to 3.0 kg per day
- Goal: Maintain body condition without excessive weight gain
Lactating (Nursing) Sows:
- Feed amount: 4.0-7.0 kg per day
- Adjust based on litter size: Add 0.5kg per piglet above 8
- Feeding times: 3-4 times daily
- Water: Critical – provide 20-30 litres per day
- Goal: Support milk production without excessive weight loss
Expected Performance:
- Litter size: 10-12 piglets
- Piglet weaning weight: 7-9 kg at 4-6 weeks
- Return to estrus: 5-7 days after weaning
- Sow body condition: Good condition maintained
Farmers with fewer than 10 piglets or who cannot afford the 100kg batch can start with 20-50kg. Transitioning to new formulated feeds should be done gradually over 2-3 days.
For farmers with big farms, they can buy a mixer, but it’s not necessary; mixing can be done on the floor with a shovel.
Do not feed or use ingredients with a Mouldy smell or visible mould growth, with a Rancid or sour odour, with the Presence of insects or rodent droppings, with Excessive moisture or clumping, or with unusual discolouration.
