Who owns the tallest horse in the world?

Jacky Iral is the owner she bred her horses well i know how she made her tall ingredients

:2 cups of Oats

1 cup of water

and 3 cups of Grain

this may make them sick for a week or 2 and you may lose your horses but if you give them it and tehy survive and you keep giving it them once a week they will grow tall once they reach 8 years old they cannot get fed this anymore or they will die thanks hope this helps :)
