Cheapest way to add oil to diet? Baileys Outshine? Linseed? Veg Oil?

[JenWizard]

My gelding needs more condition!

Following all advice, I am keeping him on a high-fibre, high-oil diet.

Whats the most cost effective way to up the oil intake?

Options thus far:

-Linseed (micronised, ground) was £35 for 15 kilos.
-Vegetable oil about £4 for 5 litres
-Baileys Outshine £35 for 20 kilos

I pay £19 for a 20kg sack of micronised linseed - definitely the cheapest way IMO.

Do you already feed chaff? If so change it to Alfa A Oil.
