Evaluation of Milk Components and Somatic Cells Count in Breeding Herd of the Slovak Spotted Cattle

Abstract

The aim this work was to evaluate the milk components and somatic cells in selected herd of dairy cows of Slovak Spotted cattle. The traits included the control samples of milk in kilograms, fat, proteins, lactose in percentages and somatic cells count as well as the correlation between given traits. By evaluation of milk yields we have find out that the average of control sample of milk production during the examined period in all the 14,160 control samples in 1,024 dairy cows was 20.69±9.69 kgs of milk with a fat content of 3.94±0.68 %, protein 3.48±0.33 % and lactose 4.87±0.21 % and 338.39±846.15 x 103 cells/ml. The correlation between the traits of milk production and the somatic cells count, for example milk in kgs, fat in %, proteins in %, lactose in % and somatic cells count in cells x 103/ml, where these values were r = -0.03679, r = 0.08985, r = 0.08830, r = -0.30855. These coefficients were statistically highly significant p <0.0001.
