Ruminant Feed Production Line in Ethiopia

RICHI MACHINERY

Project Background

Ethiopia holds the largest livestock population in Africa, with over:

• 70 million cattle (dairy and beef),
• 40 million sheep,
• 50 million goats, and
• substantial camel and equine populations.

Despite this vast livestock resource base, the productivity of Ethiopian livestock remains far below international standards, largely due to insufficient nutrition. Farmers often rely on crop residues (straw, maize stover) and limited natural grazing, which cannot meet the nutritional requirements of high-yield dairy cows or fattening beef cattle.

Currently, most commercial compound feed in Ethiopia is imported or produced by small, semi-automatic plants, leading to:

• High feed costs,
• Inconsistent quality,
• Lack of tailored formulations for ruminants,
• Supply chain bottlenecks.

Recognizing this gap, the Ethiopian government has included feed self-sufficiency in its Livestock Master Plan (LMP). The cooperative client, already managing over 15,000 head of dairy cattle and beef cattle combined, identified feed production as a strategic investment to:

• Reduce dependency on external suppliers,
• Ensure stable feed supply throughout the year,
• Improve animal productivity (milk yield and meat weight gain),
• Strengthen competitiveness in the domestic dairy and beef markets.

Thus, the ruminant cattle feed production line in Ethiopia project was conceptualized as a localized, medium-scale ruminant feed mill, directly aligned with Ethiopia’s national livestock development strategy.

Investor Profile

The investor is a large cooperative of cattle and dairy farmers based in Ethiopia’s Oromia region. The cooperative:

• Owns five large-scale dairy farms with over 8,000 lactating cows,
• Manages three beef cattle ranches focusing on fattening operations,
• Coordinates with smaller goat and sheep herders for integrated feed distribution.

Prior to this ruminant cattle feed production line in Ethiopia project, the cooperative faced several challenges:

• Unstable feed prices: dependence on imported protein meals and premixes.
• Nutritional imbalance: locally mixed feeds lacked uniform quality.
• Post-harvest losses: large volumes of crop residues (maize stover, wheat bran) went underutilized.

By investing in its own 12t/h feed processing line, the cooperative aims to:

1. Secure its supply chain by utilizing local resources.
2. Improve herd performance with scientifically formulated feed.
3. Reduce production costs per liter of milk and per kilogram of beef.
4. Supply surplus feed to surrounding farmers, creating an additional revenue stream.

This strategic investment thus combines self-sufficiency with market expansion.

Process Flow Design

The cattle feed production line follows a fully automated flow from raw material intake to finished pellet packaging.

Main Processing Steps

1. Raw Material Receiving and Cleaning
   • Corn, soybean meal, wheat bran, and cottonseed cake are received in bulk.
   • Impurities (stones, metals, dust) are removed by sieves and magnets.
2. Crushing (Hammer Mill System)
   • Coarse raw materials such as maize are ground to the required particle size (1–3 mm).
   • Ensures uniform mixing and digestibility for ruminants.
3. Batching and Mixing
   • Ingredients are weighed according to precise formulations.
   • A twin-shaft paddle mixer achieves uniform blending with CV ≤ 5%.
4. Conditioning and Pelleting
   • Steam conditioning softens fibers, improves starch gelatinization, and enhances pellet durability.
   • Ring-die cattle feed pellet machine compresses the mixture into 6–8 mm pellets, optimal for cattle and sheep.
5. Cooling and Screening
   • Counterflow cooler reduces pellet temperature to ambient +5°C.
   • Vibratory screener removes fines, ensuring consistent pellet quality.
6. Packaging and Storage
   • Pellets are bagged in 25–50 kg polypropylene bags or stored in bulk silos.
   • Ready for dispatch to cooperative farms and external customers.

Raw Materials and Material Balance

Major Raw Materials

The ruminant cattle feed production line in Ethiopia primarily utilizes locally available agricultural by-products and grains:

• Maize (corn) – energy source.
• Soybean meal – high-protein supplement.
• Wheat bran – fiber and energy.
• Cottonseed cake – protein and fat.
• DDGS (Distillers dried grains with solubles) – protein, fiber, and energy.
• Minerals & premixes – vitamins, trace elements, salt.

Typical Ruminant Feed Formula (Dairy Cattle, % by weight)

Material Balance for Annual Production

• Annual Output: 60,000 tons (finished pellets).
• Conversion Ratio: 1.02 (raw materials : finished feed).
• Annual Raw Material Requirement: ≈ 61,200 tons.

Sourcing Strategy

• Maize and wheat bran: sourced from Ethiopian smallholder farmers and milling companies.
• Soybean meal: imported from Sudan and domestic processors.
• Cottonseed cake: supplied by Ethiopian oilseed crushing plants.
• DDGS: imported in limited quantities, with plans for local ethanol industry sourcing.
• Mineral premixes: supplied by international feed additive companies.

This balance shows the feed mill’s reliance on both domestic and imported inputs, which is realistic for Ethiopia. The cooperative plans to gradually increase local sourcing as domestic oilseed and ethanol industries expand.
