The myth that alfalfa hay is bad is proven by these comments. Studies from the University of Kentucky and University of California, Davis show that protein is not hard on the kidneys, but a horse eating a higher protein content tend to drink more water and typical back yard horse owners just don't provide for this. The smell in urnine is excess nitrogen being excreted. Protein is made up of amino acids, composed of carbon, hydrogen, oxygen and nitrogen, all used for energy. There is no reason to believe the kidney's will be damaged when a horse drinks more water. BTW, more water intake means more urination. Before you start spreading rumors and hearsay, please check the facts first, you are doing the horse industry harm through your ignorance.
