What happens when your horses live on mostly straw for 10 days… and one of them decides to protest with full-blown diarrhoea? 😅 In this Q&A-style catch-up, Dr Nerida and Orla unpack a very relatable “whoops” moment and use it to teach one of the most overlooked fundamentals in horse gut health: fibre diversity.

They break down why straw is a very different beast to hay (hello, lignin), why some horses cope while others fall apart, and why “just add a product” isn’t always the smartest first move. From there, the conversation goes behind the scenes of the feed industry, mixed-species feed mills, the very real risk of ionophore contamination, and how to ask the right questions of manufacturers. Then it gets nerdy (in the best way) with least-cost vs set recipes, why crude protein can be misleading, and the lysine + leucine muscle-building “bricklayer and bricks” analogy you’ll love.

In this episode you’ll learn:

• Why restricting forage to one source can trigger loose manure/free faecal water in some horses
• Why gut “fixes in 3 hours” are usually not how physiology works (and when electrolytes can confuse the picture)
• How to read a feed label to spot vague “least-cost” ingredient wording
• Why protein quality matters (especially for young horses, broodmares, and performance horses)
