Supercal® is produced from pulverized limestone and is manufactured primarily for the animal feed sector. 

Dairy Cow

It is an off-white limestone powder predominantly finer than 2mm and available from our Exshaw and Faulkner plants in Canada. Supercal® is commonly used across several livestock classes including beef cattle and dairy. It is also often used in the poultry industry for farming both broilers and breeders. 


Supercal® is manufactured to strict specifications and tested frequently. Graymont actively managers the quality of Supercal® starting at the quarry source and continuing throughout the stages of the manufacturing process. Consistency of grind and moisture content are key attributes that are monitored to deliver a consistent product. Supercal® is available in bulk, supersack and in 25 kg bags. 


Supercal® is available from our Faulkner and Exshaw sites in Canada and is distributed further afield by request.
