How to Formulate Growers Mash Using Local Ingredients in Kenya

Are you struggling to find affordable and nutritious feed for your growing chickens? Using local ingredients to formulate growers mash can help you reduce costs, improve flock health, and boost productivity. This guide will show you how to create balanced growers mash using ingredients easily available in Kenya.

What is Growers Mash?

Growers mash is a type of poultry feed formulated for chickens between 6 and 20 weeks of age. It provides essential nutrients for growth, feather development, and immunity. Unlike starter feed, growers mash has slightly lower protein levels (16–18%) but higher energy content to support steady growth.

Why Use Local Ingredients?

Imported feeds can be expensive and sometimes hard to find. Using locally available grains and protein sources helps you:

• Reduce feed costs
• Ensure fresh ingredients
• Support local farmers
• Maintain sustainability

Key Nutritional Requirements of Growers Mash

A balanced growers mash should contain:

• Protein: 16–18%
• Energy: 2,800–3,000 kcal/kg
• Calcium: 1–1.5%
• Phosphorus: 0.5–0.8%
• Vitamins & Minerals: A, D, E, K, and trace elements

Local Ingredients You Can Use in Kenya

Here’s a list of common Kenyan ingredients and their nutritional benefits:

Ingredient	Role in Growers Mash	Protein %	Energy (kcal/kg)
Maize (corn)	Main energy source	8–9	3,400
Wheat bran	Fiber, helps digestion	15–17	2,500
Sunflower cake	Protein source	28–35	2,300
Cottonseed cake	Protein source (use sparingly)	36–40	2,500
Fish meal	High-quality protein and amino acids	60–65	3,500
Bone meal	Calcium and phosphorus	–	–
Molasses	Energy and palatability	4–5	2,800
Green vegetables	Vitamins and fiber	–	–

Simple Growers Mash Formulation Using Local Ingredients

Here’s an example of a balanced 100 kg growers mash using commonly available Kenyan ingredients:

• Maize (yellow corn): 50 kg
• Wheat bran: 20 kg
• Sunflower cake: 15 kg
• Fish meal: 5 kg
• Cottonseed cake: 5 kg
• Bone meal: 4 kg
• Molasses: 1 kg

This formula provides approximately: 17% protein, balanced energy, and sufficient minerals for growing chickens.

Steps to Prepare Growers Mash

1. Clean all ingredients: Remove dust, stones, and foreign matter.
2. Grind or crush: Ensure all grains and cakes are ground to a uniform size.
3. Mix thoroughly: Use a clean container or feed mixer to achieve a homogeneous mix.
4. Add supplements: Include vitamins, minerals, and premixes if needed.
5. Store safely: Keep in a cool, dry place to prevent mold and contamination.

Tips for Successful Growers Feeding

• Always provide clean water alongside feed.
• Introduce the mash gradually if switching from starter feed.
• Monitor growth and adjust protein levels if birds are underperforming.
• Rotate ingredients based on availability to reduce costs.

Formulating growers mash using local ingredients in Kenya is a cost-effective way to boost poultry growth and productivity. With proper balancing of protein, energy, and minerals, your chickens can thrive without relying on expensive imported feeds.

By leveraging maize, wheat bran, sunflower cake, and fish meal, small-scale farmers can create high-quality, nutritious, and affordable feed right at home.
