    • Urolithiasis in cattle is primarily nutritional and seen in highest frequency in animals fed a high-grain diet with 1:1 CA:P ratio, and in castrated males (which removes hormones that contribute to mature development of the penile urethra. Diet contributes mightily to the composition of uroliths, with animals on a high grain diet being predisposed to struvite, animals on silica contain soil have more silicate uroliths, and animals with access to high calcium diets (such as subterranean clover) may have calcium carbonate uroliths, and those with access to halogeton or sugar beet tops may have calcium oxalates.
