Can a fish extruder machine be used to produce other types of animal feed?

A fish extruder machine (especially twin-screw extruders, the most versatile type) is highly adaptable and can be used to produce a wide range of animal feed beyond floating fish feed. Below is a detailed breakdown of applicable feed types, key adjustments, and practical examples:

 

1. Aquatic Feed (Beyond Floating Fish Feed)

Fish extruders are inherently designed for aquatic applications, but they can be reconfigured to produce non-floating or specialized aquatic feeds:

Slow-sinking/sinking aquatic feed: For bottom-feeding fish (e.g., catfish, crucian carp, eels) or shrimp/crabs.

Adjustments: Increase raw material density (add fish meal, calcium carbonate) or reduce expansion (lower extrusion temperature/pressure, shorten screw residence time). Use smaller die holes or denser die designs to minimize internal porosity.

Example: Shrimp feed requires high protein (40-50%) and water stability (≥24 hours); extruders can process shrimp feed with gelatinized starch (≥80%) to prevent disintegration in water.

Ornamental fish feed: Small, colorful, or functional pellets (e.g., growth-promoting, color-enhancing).

Adjustments: Use fine raw material powder (100-120 mesh) for small die holes (0.5-2 mm), add natural colorants (astaxanthin) or probiotics, and coat with fish oil post-extrusion to enhance palatability.

 

2. Poultry Feed (Broilers, Layers, Ducks, Geese)

Extruded poultry feed offers better digestibility, pathogen reduction, and feed conversion efficiency compared to traditional pellet feed. Fish extruders can produce:

Broiler feed: High-energy, high-protein pellets to support rapid growth.

Formulation: Corn (50-60%), soybean meal (20-30%), fish meal (5-10%), vegetable oil, and amino acids (lysine, methionine).

Equipment adjustments: Lower extrusion temperature (90-110°C) to preserve heat-sensitive vitamins, use larger die holes (3-5 mm) for broiler-sized pellets, and reduce expansion to maintain pellet density (improves feeding efficiency).

 

3. Livestock Feed (Pigs, Cattle, Sheep)

Extruded livestock feed is gaining popularity for its ability to improve nutrient utilization and reduce feed waste. Fish extruders (especially large-scale twin-screw models) can produce:

Pig feed (nursery/grower/finisher): Highly digestible pellets for different growth stages.

Nursery pigs: Milk powder, whey protein, and extruded soybeans (denatured anti-nutrients) to support weaning transition. Use small die holes (2-3 mm) and high gelatinization (≥90%) for easy digestion.

Finisher pigs: Corn-soybean meal-based feed with added fat; adjust extrusion parameters to produce dense pellets (reduces dust and improves feed intake).

 

4. Pet Feed (Dogs, Cats, Small Pets)

Fish extruders are widely used in commercial pet food production due to their ability to create palatable, nutritionally balanced, and shelf-stable kibble:

Dog/cat kibble: Floating or semi-floating pellets with customized shapes (e.g., bone-shaped, star-shaped).

Formulation: Meat meal (chicken, beef, fish), grains (rice, corn), vegetables, and functional additives (glucosamine, omega-3 fatty acids).

Adjustments: For dogs (omnivores): Higher fiber content; for cats (carnivores): Higher protein (≥30%) and fat. Use a die with shaped holes for aesthetic appeal; coat with animal fat or flavor enhancers post-extrusion.

Small pet feed: Pellets for rabbits, guinea pigs, or hamsters.

Formulation: High-fiber (timothy hay, alfalfa), low-sugar pellets.

Adjustments: Lower extrusion pressure to preserve fiber structure, use small die holes (2-3 mm), and avoid high starch content (prevents digestive issues in herbivorous small pets).

 

 

 

 

MIKIM's fish feed pellet production lines and supporting machinery offer excellent value for money. Not only are they affordable, eliminating middlemen markups and allowing small and medium-sized enterprises (SMEs) and fish farmers to purchase complete sets of equipment at reasonable costs, but they also boast exceptional efficiency. The fully automated process, from raw material crushing and precise ingredient mixing to extrusion pelleting and maturation, is completed in one continuous flow. This results in high starch gelatinization rates and uniform pellet formation, significantly improving production efficiency and feed quality, truly achieving "low cost, high output." Choosing a MIKIM fish feed pellet production line means enjoying comprehensive pre-sales and after-sales service, including 24-hour online customer support, a one-year warranty on the entire machine, professional on-site installation, commissioning, and maintenance, and a stable supply of spare parts. Customers can buy with confidence and use with peace of mind, with both excellent value and service quality!
