Detailed Explanation of the Pellet Feed Processing Process

In modern aquaculture industry, pellet feed has gradually become the main feed form for livestock and poultry due to its balanced nutrition, convenient storage and strong palatability. Compared with traditional powdered feed, pelleted feed can not only improve the feed rate of animals, but also reduce feed waste, bringing higher economic benefits to breeding enterprises.

This article will systematically introduce the key knowledge in this field from the advantages of pellet feed, processing process, main ingredients, feeding precautions, and common formulas.

1. Benefits of Pellet Feed

Improving Feed Utilization

Pelletization reduces raw material stratification and picky eating, ensuring balanced nutritional intake for animals. Compared to powdered feed, feed conversion rates can be increased by 5%–15%.

Reducing Waste and Dust

Pellet feed generates less dust during storage and transportation, reducing feed loss and environmental pollution, and improving the farming environment.

Improving Palatability

Steam conditioning and pressing processes make the feed more digestible and absorbable by animals, while also killing some pathogens and improving feeding safety.

Easy to Store and Transport

Granular feed is dense, easy to pack, transport and long-term storage, and helps cross-regional breeding and export.

II. Pellet Feed Processing Process

The production process of pellet feed usually includes the following steps, each step directly affecting product quality and nutritional effect:

Raw Material Preparation and Grinding

Common raw materials include corn, soybean meal, wheat bran, fish meal, etc. To facilitate pressing and digestion and absorption, it is necessary to grind it to a suitable particle size by a crusher.

Ingredients and Mixing

According to the nutritional formula, all raw materials are accurately weighed and added to the mixer for uniform mixing to avoid nutritional imbalances.

Conditioning and Steam Treatment

Before granulation, steam is used to condition the mixed feed, so that the raw materials are heated and humidified, starch gelatinized, protein denaturated, and particle strength and palatability are improved.

Pelletizing and Forming

The tempered feed is extruded into cylindrical pellets through a pellet machine. The diameter and length can be adjusted according to the animal species and growth stage.

Cooling and Drying

The freshly released particles have a high temperature and high moisture content. The temperature and humidity need to be reduced through a cooler and drying equipment to ensure the hardness and storage stability of the particles.

Screening and Packaging

Unqualified pellets are screened out, and qualified pellets are packaged for easy transportation and sales.

Pellet Feed Ingredients and Effects

The ingredients of pellet feed generally include energy raw materials, protein raw materials, vitamins and minerals, etc. Common formula ratios are as follows:

Energy sources (such as corn, wheat, and rice): 50%–65%

Protein raw materials (such as soybean meal, fish meal, rapeseed meal): 20%–30%

Minerals (such as stone powder, salt, calcium hydrogen phosphate): 3%–5%

Vitamins and additives: 1%–3%

These raw materials can meet the nutritional needs of animals at different growth stages. For example:

For poultry, they can improve egg production and eggshell strength.

For pigs, they can promote growth and improve meat quality.

For ruminants, this type of ingredients can help better digest fiber feed while improving physical fitness.

Feeding Techniques and Precautions

Adjusting the Feed Formula Based on the Animal’s Stage

Piglets, fattening pigs, and sows have great differences in protein and energy requirements, so pellet feed with the corresponding formula should be selected.

Gradually Changing Feeds

When changing feed, a transition period of 5–7 days should be maintained to avoid indigestion caused by sudden changes in feed.

Controlling Feed Amounts

Reasonably manage feed amounts to avoid feed waste and excessive animal obesity.

Pay Attention to Feed Storage

Feed should be stored in a dry and ventilated place to prevent moisture and deterioration or mold, so as not to affect quality and the health of animals.

Examples of Common Animal Pellet Feed Formulas

How Different Farmers Can Flexibly Adjust Feed Formulas

In actual breeding, the feed formula will not remain fixed. The price, supply of raw materials, and the growth stage of animals will affect how to match them. For example, when corn prices are high, you can use more wheat, rice or sorghum to replace them to reduce feed costs; if you want animals to consume more protein, you can add some soybean meal, fish meal or other plant protein raw materials. Breeders will also appropriately supplement vitamins, minerals and trace elements based on the local climate and animal health. This will save money, and will also allow animals to grow healthier and produce more stable.

Conclusion

pellet feed is widely used in the global aquaculture industry due to its high efficiency, balanced nutrition and easy storage. Through scientific processing processes and reasonable formula design, farmers can not only improve animal production performance, but also improve economic benefits. For foreign trade buyers, understanding the advantages and production processes of pellet feed will help to select suitable products and suppliers and seize industry development opportunities.
