How are the cows that produce milk for Immunocal fed, and are they given any hormones?


Here is some information about our dairy herd from our VP of Research and Development, Mr. John Molson:

Dairy Herd and Milk Info

Our supplier, a very large reputable dairy in the United States, specializes in bioactive whey protein concentrate. They have 284,000 cows, most of whom (greater than 98%, in fact) are Holsteins. They are milked on a 305 day lactation cycle during which each cow will produce approximately 19,000 pounds of milk, or over 80 pounds of milk per cow per day. Most dairy herds are milked twice a day in traditional herringbone style milking sheds. Some of the new milking sheds are the rotary type which allow one person to milk up to 200 cows per hour. There cows are fed at a rate of about 60 pounds of feed per cow per day in order to maintain this production. About 50% of their feed consists of dry hay and alfalfa and the balance is made up of nutritious grains such as corn and soy. Some farmers feed their cows corn silage.

A full range of tests is carried out prior to milk reception at the plant including tests for Betalactam inhibitors (first and second generation penicillin antibiotics), Amoxicillin, Ampicillin, Ceftiofur, Cephapirin, Gloxacillin, Hetacillin and Penicillin). There is also random inhibitor screening for sulfonamides, macrolides, aminoglycosides, and tetracyclines. In addition, the FDA (food and drug inspectors) perform random screening for all families of drug residues on individual milk suppliers.

Further no hormones or growth enhancing substances are used.
