Regulator Self Limiting Feed


A non-salt, self-limiting supplement for feedlot or grazing cattle. Feed intakes must be closely monitored and the ratio of Regulator to ground corn appropriately adjusted to maintain desired intake.

About the Product

Self Limiting
Many factors affect supplement intake. Regulator contains a specific combination of feed ingredients that limit supplement intake, properly balance forage-based diets, and are not corrosive to self-feeding equipment.

Management Skills Required
Regulator can hold intake at desired levels if the proper level is used. The key to controlling intake is to stay ahead of the cattle. In order to do this, one must estimate supplement intake and estimate forage quality and quantity. Adjusting the concentration of Regulator is necessary to control supplement intake as forage quantity, quality and animal behavior change.

Equipment Needed
Regulator should be fed in a self feeder. The feeder must be kept clean and calibrated. Accurate intake records are necessary in order to adjust the Regulator strength for desired intake.

Tips For Managing Your Supplementation Program

  • Use the proper ratio of corn-to-Regulator.
  • Control intake by ‘staying ahead’ of cattle—adjust ratio of corn to Regulator before intakes exceed targeted levels.
  • Know your cattle and forage availability to properly estimate starting intake levels.
  • Adjust your feeders and keep them clean.
  • Record intakes.

Choice of Additives
Proper use of feed additives can increase weight gain and feed utilization; refer to product tag for specific claim. Regulator is available with feed additives at FDA-approved levels.

Feeding Directions


Mix Regulator with corn at ratios of 60:40 (corn/supplement) to 80:20 dependent upon type of cattle, age of cattle, pasture conditions and prior feeding history. It may be necessary to change Regulator mixing ratios during the grazing period to maintain desired supplement intake levels as the forage quality and quantity and animal behavior change throughout the season. Measurement of daily supplement intake is essential to proper cattle management. Supplement intakes should usually be less than 1.5% of body weight for most grazing situations.


Mix Regulator with corn at a suggested ratio of 80:20 (corn/supplement) varying the level of supplement dependent upon age, and weights of cattle, prior feeding history and desired gains. Offer medium quality hay or other roughage free choice. If in doubt of what ratio to start with, start with the higher level of Regulator and then adjust for proper intake.

Always provide fresh clean water.

General Guidelines
  Corn Regulator
Yearlings on Grass 70 30
Weaned Calves 80 20
Backgrounding 80 20
Springing Heifers on Grass 60 40
Creep Feed* 80 20

The above ratios for use with ground corn. Other grain sources are not recommended. The above ratios are starting points and may vary with conditions. When in doubt, start with a higher level of Regulator and adjust for proper intake.
