Stabilizing Mineral Premix Quality for Livestock Feed Production

The Challenge

A livestock feed manufacturer producing mineral premixes experienced inconsistent nutrient distribution in finished feed. The issue affected formulation accuracy and created concern among nutritionists regarding mineral uniformity across batches.

The production team identified that several mineral inputs had inconsistent particle size and flow behavior. This created segregation risks during mixing, transfer, and packing.

The manufacturer needed to address:

• Uneven mineral distribution in premix batches

• Variation in finished feed analytical results

• Higher quality control workload

• Risk of under-dosing or over-dosing key nutrients

The goal was to improve premix consistency while keeping the formulation practical for commercial livestock feed production.

Our Approach

The formulation and production process were reviewed to identify the main causes of mineral segregation. The evaluation focused on particle size, bulk density, moisture sensitivity, and compatibility with carrier materials.

Key considerations included:

• Particle size consistency of mineral ingredients

• Flowability during premix handling

• Compatibility with existing carrier systems

• Batch-to-batch quality documentation

A controlled mineral ingredient specification was recommended, supported by supplier quality documentation and tighter incoming inspection criteria. This helped the manufacturer reduce variability before materials entered the blending process.

The Result

After implementing the revised mineral ingredient specification, the manufacturer achieved better premix uniformity and reduced formulation variability.

Results included:

• Improved consistency in mineral distribution

• Reduced batch-to-batch analytical variation

• Lower quality control recheck frequency

• More reliable finished feed nutrient delivery

The improvement helped the feed manufacturer strengthen product consistency and support more reliable livestock nutrition performance.
