Difference between Super Fibre and Cooling cubes?

[Sunflowers1999]

This may be a silly question but what’s actually the difference between, for example, Saracen’s Super Fibre cubes and their Horse&Pony Cooling Cubes? I know the nutritional difference but would like to understand the difference in impact to the horse. For reference - the horse is an OTTB and is in light work hacking or schooling 3x weekly and lives out 24/7 with constant access to hay.

The best thing to do is ring their nutritionist line / help line , speak to them and they can advise on what’s best for your circumstances.

Look at the fibre/protein/DE amounts because that's what tells you the impact on the horse.
For a horse as you describe should be on 80% forage + 20% hard feed maximum as it's in light work.
Basis of feed should be fibre eg chaff + balancer + something with appropriate energy levels.
You feed based on age, condition, workload and temperament.
Don't go off the blurb on front of feed bags, spend time looking at the nutritional information. Ring the feed helplines.
