Bromelain--Health Food for Bossie, TooBy Judy
McBride November 23, 1999Dairy producers could benefit from
an enzyme supplement--for their cows. Bromelain helps keep the white cell count
in cows milk down in the range that fetches a premium price, according to
a recent Agricultural Research Servicestudy. Many commercial dairy cows lumber along with chronic infections of the
mammary glands that push up the number of white blood cells in their milk,
especially during the dog days of summer. U.S. dairy producers get an extra 20 cents per 100 pounds for milk having a
cell count under a specified level. That level ranges from about 200,000 to
300,000 cells per milliliter, depending on which state tests the milk.
Producers can't sell milk with cell counts above the legal limit. In the U.S.,
that's 750,000 cells/ml. Canada and Europe have lower limits--500,000 and
400,000, respectively. In the study, 75 grams of bromelain pellets daily in each cows feed
reduced cell counts by 100,000 on average during each of two trials.
Whats more, cell counts never surpassed the legal U.S. or Canadian limits
when the cows got bromelain, as they sometimes did when left untreated. The findings mean that with bromelain, producers could have more days with
cell counts in the premium price range--under 300,000. Bromelain is a mix of enzymes extracted from the stems of pineapple plants.
It's sold in health food stores under claims that it combats heart disease,
arthritis and many other maladies. In animals, it appears to reduce
inflammation by interfering with the synthesis of prostaglandins and other
inflammatory substances, according to ARS dairy scientist Max Paape in
Beltsville, Md. Paape tested bromelain, supplied by Tokyo manufacturer
Ajinomoto
Co., Inc., on 10 cows having average cell counts a little over 300,000.
