    • A method for estimating the cell count in a body fluid such as milk, by recording a MID-IR spectrum, analysing the data representing the spectral information in the recorded spectrum by use of multivariate chemometric methods for deriving properties and/or concentrations from spectral information, such as Partial Least Squares Regression (PLS-R), Multiple Linear Regression (MLR), Principle Component Regression (PCR) or Artificial Neural Networks (ANN), and deriving information on the number of cells in the body fluid from the recorded spectrum. The advantage is that the MID-IR spectrum is often measured and registered for milk samples, and an estimate of the cell count may obtained from the already registered data. Preferably measurements of conductivity, temperature, and yield are included, in order to improve the reliability of an estimate concerning the probability of a possible attack of mastitis.
    • 通过记录MID-IR光谱,通过使用多变量化学计量方法分析表示记录光谱中的光谱信息的数据以从光谱信息中导出性质和/或浓度,来估计诸如牛奶的体液中的细胞计数的方法 ,诸如偏最小二乘回归(PLS-R),多重线性回归(MLR),主成分回归(PCR)或人工神经网络(ANN),并且从记录的频谱导出关于体液中细胞数目的信息 。 其优点是经常测量和记录中红外光谱的牛奶样品,并且可以从已经登记的数据中获得细胞计数的估计值。 优选包括电导率,温度和产量的测量,以提高关于乳腺炎可能发作的可能性的估计的可靠性。
