PSVIII-36 Late-Breaking Abstract: Somatic cells count in dairy farms of Northern Kazakhstan

Abstract

Abstract According to requirements of the Safety of Milk and Dairy Products in our republic somatic cells count should be less than 750,000 cells / mL. Achieving this level is possible with the implementation of somatic cell programs based on the experience of laboratories in Western Europe and Northern America (G.M. Jones). Somatic cells in milk are counted in the United States and Canada as part of the National Dairy Herd Improvement (DHI) program. The result was a significant improvement of the dairy herd by mastitis level (Barkema H.W., Schukken Y.H., Lam T.J., Beiboer M.L., Wilmink H. et al. 1998). Average somatic cell content was less than 200 thousand cells/mL. The purpose was to determine somatic cells count in the herds of Republic of Kazakhstan and to test the SCC program. Research work was carried out under project “Improving the breeding methods efficiency.” The chemical composition and somatic cell count were carried out on a CombiFossFT + infrared analyzer. The results of counting somatic cells in milk of dairy cows in the farms of the northern region, the Republic of Kazakhstan, showed that the quality of milk in most dairy farms meets the requirements of the technical regulation on the quality and safety of milk (table 1). According to the table, it can be said that livestock of dairy cattle by 16% or more are affected by clinical and subclinical mastitis. Moreover, each farm receives less than 6% or more of milk. To increase the efficiency of dairy cattle breeding in the Republic of Kazakhstan, it is necessary to introduce a program for somatic cell counting into the practice of dairy laboratories.
