A new study conducted by the Laminitis Consortium suggests that soaking hay in summer temperature tap water makes it safer to feed to laminitis-prone horses and ponies.
The research, indicated hay soaked at 16C for 16 hours resulted in the greatest loss of water-soluble carbohydrates — which can cause laminitis.
The research was carried out by Dr Annette Longland of Equine Livestock and Nutrition Services, Dr Pat Harris of the Waltham Equine Studies Group and Clare Barfoot of Spillers.
Ms Barfoot said, "Despite this exciting study, soaking hay should always be seen as an additional safeguard. It's crucial to have your hay analysed before feeding an animal with a high risk of laminitis."
I'm not sure how practical it is for everyday, but I think it's great that there's research still getting done.
16c isn't all that warm. The safergrass study shows there correlation is much more about time than about temperature. For example, 60 minutes of soaking in cold water was more effective than 30 minutes in cold water, but about the same effectiveness as 30 minutes in hot water
Both sugar and potassium can be leached out of all types of hay in significant amounts by soaking for at least 60 minutes in clean, cold water, or 30 minutes in hot water, and draining. The average reduction in sugar over 15 samples of a variety of hays was 31%. As the amount of sugars dissolved increased over time, this suggests that a longer soaking period may allow more even more sugar to be leached.
So, they're probably saying the same thing, just in a different way.
