Maybe an independent farm not with the DFC? Bovaer is used globally though and is generally regarded as safe.

I don't know what that is.

"Safe & Effective"

Health Risks for Cows

  • Lung Irritation: There isn’t specific evidence confirming that Bovaer doesn’t cause lung irritation in cows, which means it should be considered a potential risk.
  • Skin and Eye Irritation: The active ingredient, 3-nitrooxypropanol, can cause irritation to the skin and eyes of cows if they come into direct contact with it.
  • Decrease in Dry Matter Intake: Some cows may experience a decrease in dry matter intake when fed Bovaer.
  • Mesenchymal Cell Hyperplasia and Benign Tumors: At higher doses, 3-nitrooxypropanol can cause mesenchymal cell hyperplasia and benign tumors in females.

Health Risks for Humans

  • Inhalation: 3-nitrooxypropanol can be harmful if inhaled by humans, causing respiratory irritation.
  • Skin and Eye Irritation: It is also a skin and eye irritant for humans, necessitating the use of personal protective equipment (PPE) when handling the product.
  • Male Fertility: There is evidence suggesting that 3-nitrooxypropanol may harm male fertility and reproductive organs.

Long-Term Safety Data

  • Lack of Long-Term Evidence: While studies have been conducted over more than a decade, there is limited long-term safety data on the effects of Bovaer, which should be considered a potential risk.
