Sugar Cuts Mastitis

Injecting a sugar into cows' udders to mobilize an immune system response may give producers an alternative to antibiotics for fighting mastitis.In trials at the Agricultural Research Service's (ARS) Bovine Functional Genomics Laboratory in Beltsville, Md., scientists Max Paape and Douglas Bannerman showed that injecting cows with the yeast sugar Poly-x reduced mastitis infection at one-twelfth the cost of antibiotics.

Their patent-pending approach is based on prior studies at the lab showing that increasing milk's white blood cell count will prevent infection by mastitis-causing bacteria. When injected into non-lactating dairy cows, Poly-x functions as a kind of bugle call that mobilizes the cells to attack mastitis pathogens.During the trials, the scientists injected 40 non-milking Holstein cows with Poly-x and 40 with antibiotics.

After the cows began lactating again, the scientists checked the animals for signs of mastitis infection. Those with Poly-x had a net gain of 5 new infections compared to 16 for antibiotic-treated cows, reports Paape, who, along with Bannerman, will publish the results.ARS has applied for patent protection on the Poly-x treatment, and is seeking a commercial partner that can ready it for marketing to conventional and organic dairy producers.Mastitis is an inflammation of cows' mammary glands that costs the U.S. dairy industry approximately $2 billion annually in both animal and dairy-production losses.

Today's control programs include diagnostic testing, herd separation, animal culling, teat dips and antibiotic treatment. The latter, however, can be costly to use as well controversial because of environmental contamination and other concerns.

TITLE: SUGAR CUTS MASTITIS WITHOUT ANTIBIOTICS


ALAM BA NINYO NA NATUKLASAN NG MGA AGRI-EXPERT ANG ISANG PARAAN PARA MABIGYAN NG PROTEKSIYON ANG MGA ALAGANG BAKA LABAN SA SAKIT NA MASTITIS?

ITO AY ANG ASUKAL NA MAAARING MA-INJECT SA “UDDERS” (DODO) PARA MAPALAKAS PA ANG IMMUNE SYSTEM NG BAKA AT NAGSISILBING ALTERNATIBONG PARAAN SA NAKAGAWIANG PAGGAMIT NG ANTIBIOTICS.

SA GINAWANG TRIAL SA AGRICULTURAL RESEARCH SERVICE BOVINE FUNCTIONAL GENOMICS LABORATORY, IPINAKITA NG MGA SIYENTISTANG SINA MAX PAAPE AT DOUGLAS BANNERMAN NA ANG INJECTION NG YEAST SUGAR POLY-X SA BAKA AY NAKAPAGPAPABAWAS SA MASTITIS INFECTION NA UMANOY ONE-TWELFTH SA HALAGA NG ANTIBIOTICS.

ANG GANITONG HAKBANG AY BASE NA RIN SA MGA NAUNANG PAG-AARAL SA LABORATORYO NA ANG PAGTAAS SA WHITE BLOOD CELL COUNT SA GATAS AY NAKAKAIWAS SA INFECTION NG BAKTERYA NA NAGIGING SANHI NG MASTITIS.

KAPAG ITO AY NA-INJECT NAMAN SA NON-LACTATING COWS, NAGSISILBING BUGLE CALL O TRUMPETA ANG POLY-X NA NAGPAPAKILOS SA CELLS PARA ATAKEHIN ANG MASTITIS PATHOGENS.

SA GINAWANG TRIAL NG MGA EKSPERTO, 40 NON MILKING HOLSTEIN COWS ANG NA-INJECT NG POLY-X AT 40 NAMAN NG ANTIBIOTICS.

ANG MGA BAKA NA NABIGYAN NG POLY-X AY MERONG 5 NEW INFECTIONS KUMPARA SA 16 INFECTIONS SA MGA BAKA NA NABIGYAN LAMANG NG ANTI-BIOTICS.
