RESEARCHES CONCERNING THE DYNAMICS QUALITATIVE INDEX OF MILK PRODUCTION TO A POPULATION OF CATTLE BREEDED IN THREE FARMS
In the selection process, along with the milk’s quantity obtained from an animal, an important part is its quality, which has a big influence in the recalculated milk’s quantity and also in its nutritive, energetic and biological value which the milk contains both as food and as fodder. In qualitative milk’s appreciation, mostly important is the hygienic and sanitary quality, expressed in total germs number (TGN) and the number of somatic cells (NSC). In the same time are important the fat, protein, lactose and dry substance quantity. The total germs number (TGN) obtained in the 24 examined samples has been having values between 10x1000 germs/ml and 188x1000 germs/ml, and the number of somatic cells has been situated between the values of 17000 NSC/ml and 483000 NCS/ml.
