NSC levels in the diet are important to know for horses with EMS/PPID.

NSC = Nonstructural Carbohydrates

NSC is present in forages that supply fiber in the horse’s diet.

Normal horses can tolerate NSC levels of 20% or higher. 10% NSC is the optimal level for horses with PPID or EMS. You can’t tell the NSC by looking at hay; you must get it tested.

Typical grass hays can range from 8% to 18% NSC. 

There are also several specialized hay chaff or hay cube products on the market that meet the NSC requirements for EMS/PPID horses.

Soaking hay:

  • Soak hay that is above 10% NSC to reduce sugar content.
  • Completely submerge hay for 60 minutes in cold water, or 30 minutes in hot water.
  • Drain well before feeding.
  • Soaking should only be used as a stopgap method until a more appropriate hay can be found.
  • Soaking also decreases the amount of minerals and calories the hay provides.

To encourage weight loss in overweight horses:

  1. Over a 30-day period, cut back on daily forage intake until you are feeding 1.25% of ideal body weight per day.
  2. Never feed less than 1% of ideal body weight per day of hay, as this is unhealthy. 
  3. Once ideal weight is attained, increase daily level of hay fed to between 1.5% and 2% of ideal body weight. 

Provide Adequate Vitamin and Mineral Nutrition

Skip the handful of grain and instead offer 2 to 4 ounces of Micro-Phase™ along with your hay.

Micro-Phase is designed to provide the nutrients missing from hay, ensuring your horse gets the nutrition he or she needs without the unnecessary calories.
