Lucerne Pellets in Kenya: Complete Guide to Growing, Processing & Feeding Livestock
Lucerne Pellets: Complete Guide from Field to Finished Feed
Lucerne (alfalfa) is one of the most valuable forage crops globally. When processed into pellets, it becomes a high density, easy to store, nutritionally consistent feed suitable for both smallholder and commercial livestock operations.This guide covers what lucerne is, how to grow and manage it, harvesting, processing into pellets, livestock use, benefits and how to choose the right pelletizing machine.
1. What Is Lucerne?
Lucerne (Medicago sativa) is a perennial leguminous forage crop known for:
🟢 High protein content (16–22% crude protein)
🟢 Excellent digestibility
🟢 Deep root system (up to 3–5 meters)
🟢 Long productive lifespan (3–6 years with proper management)
As a legume, lucerne fixes nitrogen from the atmosphere, improving soil fertility and reducing fertilizer costs.When dried and pelletized, lucerne becomes a uniform, shelf stable feed with minimal wastage.
2. Climatic and Soil Requirements
🟢 Climate
– Optimal temperature: 18–28°C -Tolerates drought better than most fodder crops
– Requires good sunlight (6–8 hours/day)
🟢 Soil
– Well-drained loam or sandy loam
– Ideal pH: 6.5–7.5
– Does not tolerate waterlogging
Hidden assumption to avoid: Lucerne does not perform well in acidic soils. Lime application is necessary if pH < 6.0.
3. How to Grow Lucerne
Land Preparation
🟢 Deep ploughing (20–30 cm)
🟢 Fine seedbed (lucerne seeds are very small)
🟢 Remove perennial weeds completely
🟢 Seed Rate 8–12 kg per acre (pure stand)
🟢 Row spacing: 30–45 cm
🟢 Planting depth: 1–2 cm only
Planting Method
🟢 Drill planting preferred for uniform emergence
🟢 Broadcasting acceptable but increases seed wastage
Inoculation (Important)
🟢 Use Rhizobium inoculant specific to lucerne to improve nitrogen fixation, often skipped but directly affects yield and protein levels.
4. Routine Management Practices
Irrigation
🟢 Light irrigation after planting
Established stands:
– irrigate every 10–14 days depending on rainfall
– Avoid waterlogging at all costs
Fertilization
– Phosphorus (P) is critical
Apply: DAP or TSP at establishment
Calcium and sulfur if deficient
Nitrogen fertilizer usually unnecessary after nodulation
Weed Control
– Critical during first 6–8 weeks
– Early hand weeding or selective herbicides
– Once established, lucerne suppresses weeds naturally
Pest & Disease Management
Common issues:
– Aphids
– Cutworms
– Leaf diseases in humid conditions
Control through:
– Timely harvesting
– Integrated pest management
– Avoid over-irrigation
5. How Long Does Lucerne Take to Grow?
First harvest: 60–75 days after planting
Subsequent harvests: every 28–35 days
Productive life: 3–6 years
Peak nutritional value occurs just before flowering.
6. Harvesting Lucerne Correctly
Best Harvest Stage
Early bloom (5–10% flowering)
Balances yield and protein content
Cutting Height
Leave 5–7 cm stubble
Prevents crown damage and improves regrowth
Annual Yield
8–12 tons of dry matter per acre per year under good management
7. Processing Lucerne into Pellets (Step-by-Step)
Step 1: Drying
✔️ Sun-dry or mechanical drying
✔️ Target moisture: 10–12%
✔️ Excess moisture causes mold and pellet breakdown
Step 2: Grinding
✔️ Use a hammer mill or pulverizer
✔️ Grind to 2–4 mm particle size
✔️ Uniform grind improves pellet quality
Step 3: Conditioning (Optional but Recommended)
✔️ Slight moisture or steam improves binding
✔️ No chemical binders needed—lucerne has natural lignin
Step 4: Pelletizing
✔️ Feed ground lucerne into pellet mill
✔️ Die compression forms dense pellets
✔️ Typical pellet diameter: 4–8 mm depending on livestock
Step 5: Cooling & Packaging
✔️ Allow pellets to cool
✔️ Store in dry, ventilated conditions
✔️ Shelf life: 6–12 months
8. Why Lucerne Pellets Are Important
Key Advantages Over Hay
🟢 Reduced wastage (animals cannot sort or trample feed)
🟢 Easier storage and transport
🟢 Uniform nutrition in every bite
🟢 Suitable for automated feeding systems
🟢 Nutritional Benefits
🟢 High-quality protein
🟢 Rich in calcium, magnesium, vitamins A, D, EImproves rumen function
🟢 Enhances weight gain and milk yield
9. Which Livestock Benefit from Lucerne Pellets?
Dairy Cattle
☑️ Increased milk yield
☑️ Improved butterfat content
☑️ Better body condition
☑️ Beef CattleFaster weight gain
☑️ Efficient feed conversion
☑️ Sheep & Goats
☑️ Ideal during lactation and finishing
☑️ Supports reproductive performance
Rabbits
☑️ Excellent fiber and protein balance
☑️ Improves growth and fur quality
Horses
☑️ High energy forage alternative
☑️ Supports muscle development (controlled feeding required)
Poultry (Limited Inclusion)
☑️ Used in small ratios as protein and pigment source
☑️ Not a complete feed
10. Choosing the Right Pelletizing Machine
Pelletizer choice depends on scale, power availability and production goals.
Small-Scale / Home Use
⚙️ 100 kg/hr Pellet Machine
Single-phase power
Ideal for:
☑️ Small farms
☑️ On farm feed self-sufficiency
☑️ Pilot pellet production
- Low operating cost
– Easy maintenance
Medium Commercial Operations
⚙️ 300 kg/hr Pellet Machine
Three-phase power
Suitable for:
☑️ Farmer groups
☑️ Feed retailers
☑️ Contract pellet production
☑️ Large Commercial Production
⚙️ 700 kg/hr Pellet Machine
☑️ Continuous operation
☑️ Suitable for regional feed supply
☑️ Lower cost per kg of pellets
☑️ Industrial Scale
⚙️ 1 Ton/hr Pellet Machine
☑️ Feed factories
☑️ Export-oriented production
☑️ Integrated grinding systems
Pellet quality depends more on grind consistency, moisture control and die quality than sheer machine size.
11. Final Thoughts
Lucerne pellets convert a high value forage crop into a stable, marketable and efficient livestock feed. Whether for personal farm use or commercial feed production, pelletizing improves feed economics, reduces losses and ensures consistent animal performance.
For farmers starting out, small single phase pelletizers provide an affordable entry point. For professionals, high capacity three phase machines unlock economies of scale.
