If you work cattle, you already know stress is a profit killer. Weaning, calving, hauling, handling — every one of those events triggers cortisol and inflammation, which means lower intake, slower gains, higher death loss, and more treatment costs.

FerAppease (Maternal Bovine Appeasing Substance, or MBAS) is designed to take the edge off. Applied to the nose and poll, it mimics the natural calming signals calves get from their dam, shutting down the stress response at the brain level. In plain terms: calmer cattle that eat, gain, and respond better to vaccines.

Stress doesn’t just make animals uncomfortable — it hits the bottom line:

• Reduced feed intake → poor weight gain

• Elevated inflammation → higher disease rates

• Cortisol overload → weaker immune response

• More sickness and death loss → lost revenue and higher costs

FerAppease helps interrupt that cycle.

Most people hear about FerAppease at weaning, where trials consistently show a 30+ lb advantage within 6 weeks compared to untreated calves. But that’s just the beginning. It has applications across nearly every stressful event in the herd:

• Calves: weaning, branding, dehorning, vaccination, hauling

• Cows: calving, pen moves, breeding, drying off

• Feedlot cattle: receiving, processing, finishing, pre-slaughter

In each case, the goal is the same: lower stress, protect health, and improve performance.

Recent studies give more weight to what producers have already seen in the field:

• Calving (2023 study, 345 heifers)

  • Reduced metritis

  • Better behavior at first milking

  • Increased milk production

• Pre-Weaning

  • Diarrhea cases dropped from 71% to 59%

  • Mortality cut from 7.8% to 2.4%

  • Higher body weights after pen moves

• Feedlot Receiving (Journal of Animal Science)

  • Reduced stress markers and improved immunity

  • Mortality cut by 83%

  • More liveweight gain

• Finishing (Texas A&M)

  • Carcass dressing percentage up 1–1.7%

  • Lower cortisol levels at slaughter

Application is straightforward: 2.5 ml for calves under 200 lbs, 5 ml for adults. A 300 ml bottle treats 60 calves or 30 cows. Just apply to the poll and nostrils before a stressful event.

For every $1 spent on FerAppease, operations see roughly $20 back in improved performance and reduced losses. That kind of return isn’t common in the cattle industry.

Stress robs cattle of performance. FerAppease stops that process before it costs you money. Whether it’s weaning, calving, or feedlot receiving, this tool has proven itself in both university studies and real-world use.

If you want healthier cattle, safer handling, and stronger margins, FerAppease is worth a look.
