STUDY REGARDING THE CORELATION BETWEEN SOMATIC CELLS COUNT AND MAJOR CHEMICAL COMPOUNDS IN RAW MILK
Keywords:
milk, TGC, chemical composition, correlationsAbstract
This study approaches the dynamic of somatic cells number and chemical
composition of milk during 13 months of control. The study also investigates the
correlations between the number of somatic cells and some chemical parameters in
milk. Studies were carried out on Romanian Black and White cows between March
2005 and March 2006 at the Didactical farm of the Banat University of Agricultural
Sciences Timişoara. As quality indicator, the number of somatic cells has different
values among the controls. Average values for the 13 months of control, with the
exception of three controls, were below maximum limit admitted from 1th of January
2007 (600000 SCC/ml milk). There weren’t any significant differences for SCC
between the two seasons. Chemical parameters in milk varied in close limits and the
differences were not significant, with one exception for fat percent. Fat percent is
higher (p<0.05) in the cold season 3.87% compared with 3.55% during the warm
season. Somatic cells number is weak correlated with lactose and strong correlated
with proteins.
