Somatic cell count

Reducing Somatic Cell Count in Dairy Cattle

Published: February 27, 2012
Summary
Somatic cell count (SCC) is the total number of cells per milliliter in milk. Primarily, SCC is composed of leukocytes, or white blood cells, that are produced by the cow´s immune system to fight an inflammation in the mammary gland, or mastitis. Since leukocytes in the udder increase as the inflammation worsens, SCC provides an indication of the degree of mastitis in an individual cow...

In India hand milker usually uses cold water to wash the teats and also fails to scrub the teat pore before milking. Milker is supposed to use warm water to wash the teat and rub the teat pore to dislodge any dirt accumulated. Many milkers knuckle the thumb and strip out the milk, if the teat is not lengthy especially first calver the milking is done by stripping the teat from base of teat to the tip of the teat especially in the later situation too much accumulation of blood at the teat pore causes the callus formation. When a machine is used for milking over milking or creeping up of liners can also result in such callus formation a predisposing factor for sub-clinical or clinical mastitis. In majority of milking machines it is not possible to turn off the vacuum for individual teat when the milk out flow has stopped and in few instances even without proper turning off the vacuum the cluster is removed and possibility of entry of air in to the teat cistern can be a factor to increase somatic cell count. All teat dips are not 100 percent efficient in their antiseptic properties. If a spray is used the milker may not spray 100 per cent efficiently for this reason teat dip is preferred by the dairy mangers. In India there is no suitable intramammary infusion to do DRY COW THERAPY and if the organisms can enter in to the teat cistern on the last day of milking they can remain in the udder up to 200 days (information from Hoard's dairyman) and when the resistance of the animal comes down they can cause sub clinical or clinical form of mastitis.

All these predisposing factors have to be managed to reduce somatic cell count. The other nutritional factors and stimulating the immunity system are required to reduce somatic cell count. Vaccinations unless they are done in late pregnancy followed by booster vaccination dose and at specified subsequent intervals it is not worth.
Estrogen is required for the muscular strength of myoepithelial contraction and for the milk ducts while progesterone has a role on the secretary tissue of udder. Estrogen is required for the muscular tissue of uterus especially in pregnancy for the hypertrophy of muscular fibers and progesterone for the uterine endometrial secretions. Clinically it is well documented when the uterus is infected there is a drop in milk production. In sub clinical and chronic clinical mastitis condition animals do become repeat breeders. The flux of these two hormones may have a role in somatic cell count.

Dear Sir, What is the formula for the SSC . Some author count average cell count X microscopic factor X 8000 or 50000. Please advise correct formula for the SSC. Thanks and regards. Dr Mehatre S N

Hi Drs Viswanath and Reddy, Please go through our article on" Pathobiology, etiology and treatment of ...mastitis" which appeared in this forum . It explains most of the problems of mastitis and its control. Jasmer

Hi , Can any body share the role of Lauric Acids and Glycerol in reducing the Level of SCC in milk ?

Dear all, From the animal nutrition side, the use of Copper and Zinc (preferably chelated with methionine or glycine) have shown to reduce SCC dramatically. The company NOREL Animal Nutrition (www.norel.es) counts with really good chelated minerals with methionine and or glycine. Regards, Alfredo.
