The influence of postpartum metabolic disease on the milk composition in the first hundred days of lactation in dairy cows
Original language description
The goal of the study is to monitor the parameters of milk in dairy cows during the first 100 days of lactation. The cows, breed of Czech Pied (n = 1918) were included in the trial. Data gained during the regular control of performance were gathered during two years and analysed and processed in program Milk Profit Data. According to the results, the health of the herd was evaluated. The correlation between the individual parameters and the occurrence of metabolic disease was observed. Data of Milk Profit Data were divided into three groups (According to the stage of lactation - first 21 days, a period from 22 to 60 days, and the rest of it). In the milk samples selected parameters were analysed (milk fat, milk protein, fat/protein, lactose, somatic cell count (SCC), milk urea, citric acid, β-hydroxybutyrate, acetone, free fatty acids). The number of lactation, the day of ongoing lactation and the yield are also known from the control of performance. Based on the results, the correlation between negative energy balance and increased values of ketone bodies as β-hydroxybutyrate and acetone were observed. There is a statistically significant difference in the amount of fat in milk between the first 21 days of lactation (4.10 +- 0.70%) and the rest of the observed period (3.83 +- 0.62% and 3.87 +- 0.60%). That is related to the lipolysis at the beginning of lactation. The older cows on the higher number of lactation are much more predisposed for ketosis development. That is confirmed by the positive correlation between the amounts of BHB and number of lactation.
