 Equine urine can be very cloudy and foamy, and rather viscous, depending on the horse's diet. (see Figure 5.1)

 The cloudiness results from the high concentration of calcium carbonate crystals.Diets high in calcium (e.g. alfalfa) are associated with higher concentrations of calcium carbonate crystals in the urine.Excess dietary calcium is eliminated in the urine and feces.The majority of equine uroliths are composed of calcium carbonate.Figure 5.1 Image of a sample of horse urine. The urine appears cloudy and foamy which is a normal finding.

  The foamy and viscous nature of equine urine is due to its high concentration of mucus.Gland‐like structures in the wall of the equine renal pelvis secrete a mucus‐like substance.Mucus has a lubricant function, and helps in preventing the formation of urinary stones from small calcium carbonate crystals.
