How is rabbit food made?

A while back I happened to be at BSAVA at the same time as the Technical Manager for Supreme Petfoods, knowing very little about pet food manufacturing at this point in time I decided to ask as many questions as I could. Now I am going to try and explain the process (at least at Supreme Petfoods) to you!

Starting at the beginning of the process we have to consider the type of formulation process used. There are generally two types here:

  • Fixed formulation – Now fixed formulation is simply that, it means that every single time the food is made with the same ingredients. Take for example cranberry’s, if the formula says that 1kg of cranberrys should be used then 1kg of cranberrys is used. It doesn’t matter about the market price of the ingredient, if the cranberrys cost £1 or £10 they are still used in the same amount.
  • Dynamic (nutrient based) formulation – Now dynamic formulation is all about the end nutritional value of the food. This means that it just so long as the end nutritional values are correct whatever ingredients it takes to get there are used. Generally this could mean the cheapest possible ingredients are used, there is actually computer software that will calculate the recipe based on the cheapest prices at that point in time.

Now Supreme Petfoods use fixed formulation, this means that every time you buy a new packet of food it is exactly the same as the last time you brought that food. The upside to this is your rabbits not looking at you crazy for giving them a different food.

All these ingredients are then processed (whether it be by grinding or cutting) before they are all mixed together. This is then passed into something called an extruder, its basically a big machine that will squeeze the food out through a die for the correct shape and cut it into the correct sizes… Kinda like one of the old play dough machines but on an industrial scale.

This will then pass into a drying tower which will remove the moisture from the food using heat and time, before it then passes into a cooling tower to allow it to return to room temperature before then heading to a packing line where it is sealed in bags ready for distribution.
