Have you ever heard of this. I was researching and this came up several times to help mares increase their milk production. Some say they feed it 6 weeks before the "due date" and others start as soon as the mare foals. I had never heard of it. Is anyone her familiar with it?
I googled -- google is such a funny thing. First reference was in horsesandhoundsuk bb and had great anecdotes about using on broodmares to improve milk. Second one said:
"Cocoa powder can be fatal for animals such as horses, dogs, parrots, small rodents and cats. They cannot metabolize theobromine and caffeine found in chocolate as effectively as humans."
Though source #1 was talking about a tablespoon or so, and source #2 mentioned "excessive amounts" which for a horse may be considerably more than a tablespoon!
It must be the fat or calcium, both of which could probably be obtained somewhere else more easily.
Shall I tell you what I find beautiful about you? You are at your very best when things are worst.
