The most important factor affecting SCC milk from a quarter, a cow or a herd is a quarter of infection status. Various authors have reported an average SCC for the uninfected quarter to 170,000 to 214,000 cells/ml or the geometric average of 106,000 cells/ml. Somatic cell response of the infected cow will depend on the pathogen. You can find Saber Milk Sensor online.
Individual cow somatic cell count is the product of the SCC measurement of all milk from all four quarters and production levels of the individual quarters. The number of infected quarters and total milk production is an important factor to be able to accurately classify as infected cattle by means of SCC. The dilutive effect of normal milk can cause mask infection. Researchers in Canada have found that cow’s ability to correctly classify as being infected or not infected by SCC increased from 77.9% to 92.7% as the number of infected quarters increased from one to four quarters.
SCC from individual cows can span a very wide range of values. To classify cattle as infected or not infected with any SCC manner appropriate threshold level should be selected. This threshold will vary from herd to herd.
Regardless of the level of the chosen few infected and uninfected quarters will be misclassified. Increase the possibility of isolating the primary pathogens when the SCC quarter was above 200,000cells / ml. SCC is a composite of the quarter shows that the threshold value of about 250,000 cells/ml is reasonable to differentiate infected from noninfected 5/4. A threshold of 228,000 cells has been demonstrated to correctly classify over 85% of the cows.
