Gypsum Bedding Products and Additives

Grip X1 Barn Dry, animal beddingWhy Gypsum Animal Bedding?

  • Soft material keeps cows clean, dry and comfortable
  • Gypsum is more absorbent than sawdust or shavings
  • Gypsum can reduce cell counts and Mastitis problems
  • Gypsum can reduce foot health problems
  • Non Caustic and safe.  Doesn't burn or cause dried skin or feet like hydrated lime.

Organic bedding materials, such as sawdust, shavings, straw and corn fodder are typically used by the dairy industry. However, these organic bedding materials support conditions (moisture, nutrients, and rich pH) which are more ideal for pathogenic growth than inorganic (gypsum) bedding. Using mineral bedding materials will decrease teat end exposure to environmental mastitis pathogens.


Carbon and other nutrients essential for bacterial growth are more available in organic bedding than in gypsum bedding. Dry matter content of most organic material is often less than 70% versus greater than 90% for gypsum bedding. Besides that, drier bedding will result in fewer flies, slip resistance and an odor free area.



Gypsum bedding pays you back!

- Increases the fertilizer value of your manure

- Reduces fertilizer purchases


A chemical reaction between gypsum and ammonia, in urine ties up the ammonia in the form of ammonium sulfate. Odor is reduced and the environment in the barn is improved. The retained ammonia increases the natural nitrogen in the manure. Using wood bedding products sours your soil and may require additional lime to sweeten the soil.


Because gypsum bedding, combined with manure, is spread on croplands, it has value as a source of additional nitrogen, calcium and sulfur. Most farmers purchase these products for their crops so the cost of gypsum bedding is recovered. Gypsum is soluble and penetrates soil without incorporation. Thus, it is an excellent source of calcium and sulfate for pastures, alfalfa and no-till.


Are phosphorus levels limiting your manure application?

Gypsum reduces the amount of phosphorus carried by rainwater run-off. Having a PSC test done on your manure will enable your Nutrient Management Plan to be based on your manure’s phosphorus loss risk, not the book value. Book value for PSC is often higher than your farm-specific manure test.

Gypsum Pellet Bedding

Analysis Gypsum 88% Paper Fiber 12%

The dried gypsum granules are made up of many small particles with voids which enhance the absorbing power. Gypsum pellets draw moisture which keeps cows cleaner and drier. It supports conditions which decrease the source of pathogens that cause mastitis and increase cell counts. Use of Gypsum Pellet Bedding also reduces the bedding rate and labor costs. The off white color brightens the area, gives the barn a clean appearance, reduces odors and is harmless to livestock.


Ideal for use in stanchions, free stalls or bedded packs. Use as an additive to sawdust, shavings or other bedding by premixing or alternating applications. Spread a thin layer that does not entirely cover the mattress or broadcast over bedded packs. Moisture is drawn to the particles. Add additional Gypsum Pellets as needed. Low dust, free flowing material that works well with bedding spreaders.  Available in bulk or 40lb bags.

Paper + Gypsum

compost additivesAnalysis Gypsum 51% Paper Fiber 49%

Ideal bedding for Compost Bedded Pack Barns. Gypsum residual with the shredded paper aids the composting process. Since the 1920’s, professional composters have used gypsum as a compost additive. Composting of organic materials leads to loss of nitrogen via ammonia volatilization. Gypsum helps to retain nitrogen and aerate the bed pack for better air penetration. Paper + Gypsum also helps to balance the carbon to nitrogen ratio of the compost, and absorbs more moisture than sawdust, shavings, corn fodder or other organic materials. Paper + Gypsum can also be used as an additive to normal bedded packs with similar advantages. Available in bulk shipments.
