Phase Feeding

Match the nutritional requirements of pigs throughout their growth cycle

What is phase feeding?

In simple terms: phase feeding means changing an animal’s diet according to their age and weight.

With a phase feeding system, you can make strategic dietary adjustments to ensure your pigs’ nutritional requirements are met at the right stage in their growth cycle.

Why phase feed?

If pigs are fed a single diet over a long period of time, their nutritional needs might not be properly met.

Naturally, this can have a negative effect on their growth performance.

On the other hand, switching quickly between diets to keep up with the pigs’ changing condition may cause growth stunts.

Phase feeding eliminates both of these problems.

How it works

With phase feeding, the amounts of each feed ingredient that are present in the mix are gradually adjusted over time.

There are no sudden switches; instead, the ingredients are slowly changed according to the amounts pre-programmed in the system.

This creates a smooth transition between diets that have been specially mixed to suit the pigs’ stage of growth.

Using the system

First, you pre-set the feed curve (or curves) to automatically adjust the ingredient amounts as your pigs grow.

Then, you apply the curve to your chosen group and let the system handle the incremental transitions.

Benefits of phase feeding

Because phase feeding allows you to gradually switch feed mixes, you can target your pigs with the nutrients they need at their particular age, weight, and condition.

With this level of advanced feed management, you can expect:

  • Improved feed conversion
  • Greatly reduced feed wastage
  • Minimised growth stunts
  • Better growth performance

Available systems

We offer two phase feeding systems: Ration Feeding and Multifast.

The Ration Feeding system allows you to call up to 4 diet ingredients from the silo to be layered in the conveyor and delivered to your selected group.

For larger units and more finite mixes, Multifast allows up to 8 feed curves and 20 different ingredients. These are then weighed and blended in the mixer-weigher.

Should your unit size increase in future, Multifast is easy to extend.

However, both Ration Feeding and Multifast systems have multiple benefits:

  • Enhanced analysis for research and advanced management
  • Assign bespoke diet curves to individual pens
  • Gradual transition between diets, avoiding expensive growth stunts
  • Target pigs with the right nutrients at the right time
  • Get a daily overview of consumption per feeding place for effective feed management

  • "Before installing the system I was was feeding 5 kilos of bought in ration but because of the ability to create the right mix this has now reduced to 2 kilos.' Not only this but phase feeding creates a better transition"

  • "I spoke to Collinson, Adrian, the chap I worked with was really helpful and their flat rate system, Equity, seemed like a good piece of kit, it is robust and was exactly what I was looking for, I completed my system with a Collinson silo which is galvanised with a Slate Blue Plasteel finish and a conveyor to take the feed from the silo into the parlour. I would definitely recommend Equity"

  • "We were very impressed with your sales staff’s knowledge & speed at dealing with our enquiry. The auger system was fitted on time & very smartly by your fitter, we were very impressed throughout. We chose Collinson after using the same Collinson feed bin over 30 years, the same one the auger has just been fitted too. Thank you."
