Learn how feed troughs are designed and fabricated for various livestock species. Discover material selection, anti-waste design features, and real-world farm installations.
Introduction
Feed troughs are essential components of livestock feeding systems, holding feed for animal consumption. Trough design affects feed efficiency, animal welfare, and farm profitability. Poorly designed troughs can lead to feed waste, contamination, and animal injury. At Fulei Metal, we fabricate feed troughs for cattle, sheep, pig, and horse operations across multiple continents.
Feed Trough Design
Trough profiles must minimize feed waste by preventing animals from pulling feed out. We design troughs with rolled edges, internal lips, and appropriate depth-to-width ratios. Trough length must provide adequate feeding space for all animals, typically 300 to 600 mm per head for cattle. Trough height must be appropriate for the animal species, with cattle troughs at 600 to 800 mm and sheep troughs at 400 to 500 mm. Trough designs include wall-mounted, fence-mounted, and freestanding configurations.
Material Selection
Hot-dip galvanized steel is the standard material with zinc coating providing corrosion resistance against feed moisture and animal saliva. We use 1.0 to 2.5 mm sheet. For troughs in contact with wet feed or in corrosive environments, stainless steel (grade 304) provides superior longevity and hygiene. For enhanced appearance, powder coating over galvanized steel is available in various colors.
Design Considerations
Troughs must be designed for easy cleaning with smooth surfaces, rounded corners, and drainage features. Drain plugs allow regular cleaning and water removal. Troughs must withstand animal pressure, feed abrasion, and cleaning operations with adequate material thickness and structural reinforcement. All trough edges must be smooth or rolled to prevent animal injury, and mounting hardware must be secure and inaccessible to animals.
Fabrication Process
Our TRUMPF fiber laser cuts trough blanks from flat sheet stock with precise dimensions. CNC press brake machines form trough bodies with complex profiles including rolled edges, internal lips, and drainage features. Trough assembly uses MIG welding for galvanized steel and TIG welding for stainless steel, with all feed-contact welds ground smooth. Galvanized troughs are hot-dip galvanized after fabrication, with stainless steel troughs possibly electropolished.
Case Study: Feed Troughs for a US Livestock Producer
Feed troughs fabricated for a major US livestock producer form part of a supply relationship running since 2016, with stainless feed-contact components at around 5,000 pieces a year. A trough looks like the simplest item in a livestock range, and it fails in a predictable way. Feed and water collect in the bottom corner, the corner is the hardest place to clean, and over time that is where corrosion begins and where the finish breaks down. The answer is in the forming: the bottom is formed with a radius rather than a tight fold, drainage is built into the geometry so that nothing stands in the trough, and joints on the feed contact surface are welded through. Radiused corners also survive handling better – a tight fold in a trough that is dragged across a yard will open up.
Conclusion
Feed trough fabrication requires understanding of animal feeding behavior, feed efficiency, and corrosion protection. Fulei Metal’s experience in livestock equipment fabrication makes us a trusted partner for feed trough projects.
