The impact of subclinical mastitis on milk compositional and sensory quality was investigated in small holder farms in Kenya. A total of 80 udder quarters from 40 lactating Toggenburg dairy goats were collected and analyzed to assess the composition and component variation in subclinical mastitis infections. Intramammary infection were recorded in the halves and analyzed to determine the most frequently isolated pathogens. The mean value of FFA (expressed as acid degree value (ADV) obtained was 3.76±7.95 x10-1 significant at p<0.05. Somatic cell count (SCC) levels were estimated using the California Mastitis Test (CMT) and verification done in the microbiological laboratory. The SCC values were transformed to log10 prior to analysis. The mean SCC was 3.8x106± (2.54x105) cell/ml. The mean pH of the milk was 6.72 ±0.1. For each of the results, descriptive statistics, the Pearson correlation coefficients and linear regression were calculated to investigate the relationship between SCC levels, FFA content (ADV values), pH and the sensory characteristics of the milk. It is concluded that subclinical mastitis gave off –flavor and reduced overall quality and quantity of milk.
