The reduction in production of milk is the major expense associated with the subclinical and clinical mastitis. An influential factor is the existence of the tassel of the tail of the animals, which helps to the pollution of the quarters, contributor of 60% of total milk (García, 2004). A similar procedure of prevention of mastitis is used commonly in the New Zealand herds where there is amputated the portion of the tail that presents the tassel. This practice helps to anticipate mastitis avoiding the dirt as factor of risk for the disease. (Vela, 2009). This paper tries to establish a regional level, which may be the impact of cutting the tassel of the tail in terms of: the presence of mastitis by the California test, somatic cell count (RSC) using Mastitec forming units and counting colony per milliliter (UFC/ ml) by deep planting on agar plate count. 15 were selected for this experimental units completely at random, on two farms in the highlands of Cundinamarca and Boyacá, which bear similar characteristics. The 30 animals were subjected to two samples before and after the cutting of hairs of the fringe with a one-week interval between sampling, for analysis as described above. At the end of the process noted that the technique implemented on farms treated, has a statistically significant effect in reducing mastitis, somatic cell count and colony forming units in the hindquarters.
