cow’s INTENSELY PAINFUL foot … takes a surprising turn?

The Impact of Biotin Supplementation
Biotin, being water-soluble, is not stored in the body and must be consumed daily. Studies have shown that a Biotin-based supplement, administered at a dosage of 12-15 mg per day for a 1,000 lb horse, can lead to improvements in hoof integrity within 3-5 months, with maximum benefits observed up to one year. The enhancements include:

Increased tensile strength of the entire hoof wall
Reduction in cracking and splitting of the horn
Significant improvement in hoof horn hardness and thickness
Better condition of the white line
Accelerated hoof growth after a 90-day period
Horses with tender feet exhibiting more freedom and confidence in movement
After 6-9 months, further improvements such as stronger perioples, better hoof horn surface, deeper heels, improved hoof shape, and easier shoeing due to a stronger hoof horn
