This is not the article I was reading but it covers part of what it said. I have never heard of this but it sounded good and thats why I asked. Heres the article I could find:
Many farmers have reported good results from the use of food grade H202. Claims have been made of reduced disease, increased butterfat in milk, higher egg production, heavier chickens and healthier fruit and fish. The following is a summary of how some farmers and ranchers use H202:
Drinking Water for Farm Animals: Use 8 ozs. of 35% food grade H202 per 1000 gallons of water or 30 ppm.
Dairy Barn: Use as a pipeline rinse for milkstone. As a rule, 2 to 4 ounces of 35% H202 to 15 gallons of water will work with good results. Also works well for rinsing milk cans and bulk tanks to keep down bacteria as well as milkstone.
Power Wash: To sanitize dairy barns or hog houses use enough hydrogen peroxide to cause a light foaming action when spraying the floors and walls. Leave this until the foaming subsides, and rinse again. If foaming recurs, either raise the amount of H202 or continue at the same level and respray.
Udder Wash: Use 1 oz. of 35% H202 to a gallon of warm water. The cows tend to have softer teats and are freer of bacteria which reduces bacteria in the bulk tank.
Colostrum Milk: To keep if from spoilage until it is all fed to the newborn calf, depending on the time of year, pH of the milk, temperature, etc., one can use from 1/4 oz. to up to 1 oz. of 35% H202 per gallon of colostrum milk.
Newborn Calves: To add extra oxygen, add 10 to 15 drops 35% H202 to a bottle of milk, morning and evening, per calf. This has helped to brighten up calves and in some cases of scours, depending on the pH of the milk being fed.
Drench: For high fever and off- feed cows with mastitis, depending on the situation and case, mix 1 to 2 ounces of 35% H202 to 1 quart of water, drenching the animal morning and evening for as long as needed, usually 2-3 days.
Ailing Cows: Use 1 pint of 3% H202 to 5 gallons of water.
Induce vomiting: Use 3% H202.
Animal Wounds: Clean wounds of animals with 3% H202.
Afterbirth of Cows: Cows settle and clean out faster after giving birth to a calf when H202 is added to their drinking water.
