Our Promise
At Rakaia Engineering we know farming’s a tough job because we’ve been working with New Zealand farmers for over 20 years. We are committed to designing & engineering hard wearing, accurate feeding systems for your farming operation.
Researched & developed on-farm for over a decade & experienced in a multitude of systems, Rakaia Engineering’s PROFEED in-dairy, piggery & poultry feeding systems are designed to improve production & stock health, right the way through seasonal & nutritional demands.

You’ll find our complete range of PROFEED feeding systems to be precise, hard wearing & loaded with practical user-friendly features. They’re easily installed into new & existing rotary & herringbone dairy sheds.
What’s more - our all-inclusive service combining custom design, in-house manufacture, direct importation, installation, commissioning, operator training & after sales support, aims to deliver a long-lasting turn-key solution for your dairy operation.

Supplementary Feed
• Crushed Wheat or Barley
• Protein Pellets
• Mineral Pellets
• Palm Kernel
• Custom Blends
• Soya Protein
Molasses can also be dispensed in conjunction with supplementary feed.

• Fills a feed deficit during lactation

• Increases production without increasing cow numbers

• One of the cheapest ways to boost production with limited acreage

• Cows benefit from supplementary feed matching their dietary & health requirements as well as seasonal weather conditions

• More accurate feed budgeting & allocation of supplementary feed

• Cows cycle better resulting in fewer issues with conception

• Secure bulk feed at more competitive prices

• Minimal feed losses

Rakaia Engineering’s imported & locally manufactured silos are designed for superior clean out & improved farmer safety. We have available an abundant range of silo options to cater for individual storage & feed requirements.

Silos for bulk grain storage range from 30 up to 300 tonnes, whilst hopper silos for crushed grain, palm kernel, pellets and other products range from 4 up to 40 tonnes.

Advice & consultation
Our nationwide customer service team offer obligation free on-site consultations & assistance to determine the right feeding system requirements for your farming operation. PROFEED feeding systems are designed & manufactured in Canterbury.

Design
We appreciate the back-bone to any operation is efficiency and that’s why we’ve worked hard to design & develop a feeding system which is robust, fully automated & quick to install.
We also provide a 3Dcad design service

Manufacture & installation
At Rakaia Engineering we only use top quality materials & componentry in all our PROFEED feeding systems. We’ve developed long-lasting relationships with our international suppliers & carry a range of spare parts to ensure your feeding system remains in top condition for years to come.

Nationwide after sales support
Our skilled & experienced sales & service agents throughout New Zealand, provide a prompt repair & maintenance service.

A typical PROFEED system comprises one or more storage silos & feed lines, grain crusher, crushed grain silo, additives hopper, coreless auger delivery system & continuous stainless steel trays. All PROFEED systems are easily integrated with automatic Cow ID systems in rotary dairies.

Coreless auger options are:
Model 220 with a capacity of up to 7kg per min, Model 350 with a capacity of up to 45kg per min & Model 500 with a capacity of up to 100kg per min at 640kg/m3.

The capacity & bulk storage capacity of our entire range of PROFEED systems can easily be expanded at a later date to accommodate your supplement requirements.

How does the system operate?
As the 2 way limit switch comes into contact with the bail post it sends a signal to the auger motor which will run for a set time (this adjustable timer is set by the farmer). The supplement (along with molasses if required) is then released in front of the cow, two bails in from where the cow comes onto the platform.

Sensor PLC
The most popular choice by far, sensor PLC’s deliver a multitude of benefits including ease of operation & greater accuracy.

The system provides complete automation including miss a bail for “no cow in bail” & “second time around” with the flexibility of manual override.

Standard PLC
The main difference between the two PLC’s is that the system requires the operator to skip bails by manually operating the “miss a bail” button.

Profeed’s Herringbone feeding system works simply by the selected feed being transferred from the silo, into the dairy & filling individual dispensers on each side of the shed.

When the cows come in for milking the operator pulls a leaver situated for each side in the pit & the measured amount of feed is deposited in front of each cow. While the cows are feeding, the dispensers are automatically filled, ready for the next row of cows.

Model 350 - Premium Ration Dispenser
All ration adjustments are automatically managed from a push button control located in the pit. There’s no manual requirements - the fill augers and dispensing augers are automatically & simultaneously adjusted from this in-pit control,
making light work of altering ration requirements between am/pm milkings, or within a herd/row. Up to 8kg rating.

Model 220 - Standard Ration Dispenser
To alter ration volumes each individual dispenser is manually adjusted. Up to 5kg rating.
