Baileys horse feeds - any thoughts?

I've come to a conclusion that my 6yo horse could use some additional feed, as I have increased his workload from light to moderate and thinking of beginner level competitions, and I've been eyeing Baileys feeds, to be exact - this one No.13 Oat-Free Horse

Any thougts on the quality of this product and Baileys products in general?

He is currently grazing in grass pastures 24/7 and fed 900g (about 1.9 lbs) of soaked whole oats with phytotherapeutic vitamin and mineral supplements once a day.

I suspect that the Baileys range is different where you are, but in principle Baileys are very good, and they do do 'what they say on the packet'.

I have used Bailey's number 1 before now, and a friend swears by their Number 4 for keeping weight on her TB.

That sounds really promising - thanks for your input!

So I have started Snickers on Baileys number 9 - it really does what it says on the package! I'm content with this choice, and Snickers is too.
