Your 80/20 alfalfa/grass mix supplies ample calcium. What does 1 1/2 am and pm mean? Is that flakes? You need to calculate how much hay you feed by weight, not volume. Your horse should be consuming 2% of his body weight daily in forage. If he weighs 1,000 lbs. that means 20 lbs of hay. |
I would be more concerned about a high calcium to phosphorus ratio than an excess of phosphorus, even after factoring the amount of rice bran and flax that you are feeding.
White line disease is hoof wall separation that has progressed to infection inside the white line, and can continue into the sensitive laminae. Contributing factors are allowing the feet to go too long between trims (walls too long), feeding a diet too high in starches/sugars, and trace mineral imbalances/deficiencies. Virtually all forage is high in iron and deficient in copper/zinc. The Nutrena senior won't fix that and is also very high in iron. Your farrier should have some suggestions for dealing with the mechanical issues of the feet, and a diet evaluation with a nutritionist such as Clair Thunes will help get your horse's diet better balanced.
