The Effect of Somatic Cell Counts in Early Lactation on the Next Milk Production

Original language description

The principal parameter routinely used internationally in this context is the somatic cell count (SCC) of milk and the total bacterial count (TBC). Mastitis has enormous economic importance, because mammary inflammation during mastitis causes a range of physical, microbiological and chemical changes in the milk and it is decreased the amount of milk. In our study we followed the effect of SCC in the first month of lactation on observed parameters and effect of lactation stage of the quantity of milk produced in the context of a different SCC. Individual milk samples (7531 samples) were obtained from whole milk collection as an average sample once a month. Milk yield and its composition (fat, protein and lactose), and somatic cell counts - SCC (log x SCC per ml) were evaluated. On the monthly basis of SCC the cows were divided into following groups: SCC below 3 x 105 cells/ml (low group LG), between 3 x 105 and 1 x 106 cells/ml (high group HG) and SCC over 1 x 106 cells/ml (very high group, VHG). Dairy cows were divided into five classes according to stage of lactation as lactation days. While at low SCC dairy cows milked an average of 13.56 +- 0.14 kg of milk, at very high SCC, it was only 12.74 +- 0.2 kg. SCC in the milk has not the fat content affected. The proteins we found only a lower increase in relation to increasing SCC. Lactose had by low value of SCC on average 5.28 +- 0.02%, high SCC in milk decreased lactose content to 4.68 +- 0.02%, and at very high SCC was recorded value of 4.64 +- 0.01% lactose. The amount of milk either at the beginning or at the end of lactation was lower in cows with higher SCC in the first month of lactation.
