The Effect of Somatic Cell Counts in Milk During Lactation on Milk Yield and Composition
Original language description
The study devoted to to the possible effect of SCC on milk yield and its composition under the practical farm conditions. Into experiment 580 dairy cows were enrolled throughout whole lactation (Slovak Pied - 70% and the remaining 30% form a crossbred Holstein and Pinzgau). Under regular milk recording treatment the milk samples (3420 samples) were collected monthly and analysed in certificated laboratory of Slovak breeding services š.p. Bratislava. Milk yield and its composition (fat, protein and lactose) and SCC (logxSCC 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 6 x 105 cells/ml (middle group MG), between 6 x 105 and 10 x 105 cells/ml (higher group HG), between 10 x 105 and 30 x 105 cells/ml (highest group HiG) and SCC over 30 x 105 cells/ml (ill group, ILG). SCC significantly (p < 0.05) reduced milk yield per milking from 10.76 +- 0,317 kg in LG (LS means +- standard error) to 8.36 +- 0.381 kg in ILG. So the work points to a relationship of production and udder health. Protein slightly but significant increased from 3.56 +- 0.024 % (LG) to 3.66 +- 0.03 % (ILG). Fat content was constant in first four groups (around 3.95 +- 0.051 %) with significant increase in ILG (4.16 +-0.073 %). Lactose significantly reduced from 4.66 +- 0.022 % in LG to 3.65 +- 0.027 % in both HiG and ILG. SCC significantly negatively influences milk yield and its composition which was clearly proven under practical conditions. Data from regular milk recording should be used for significant improvement of dairy management.
