Shift Your Pigs from Surviving to Thriving

Stress and aggression is known to induce drastic changes in the way pigs utilize nutrients.

Epinephrin & Cortisol

The stress hormone epinephrin is known to increase gastrointestinal movement which causes nutrients to exit the body before they are fully digested. A second stress hormone, cortisol, is known to induce insulin resistance and catabolism, meaning that fat and muscle tissues are breaking down to provide energy to the stressed body.

Survival Mode

Stressed pigs are in survival mode, where the priority is to provide resources to the body in order for flight or to fight an eminent treat, and this metabolic status is very energy inefficient. You can overcome this obstacle with FerAppease MSAS.

FerAppease MSAS

The active ingredient of FerAppease is a synthetic analogue of the Maternal Swine Appeasing Substance (MSAS). MSAS is a naturally occurring substance that is secreted by the skin of the mammary gland of lactating sows, eliminating stress in all swine treated.
