Resumen
Descripción
The aim of this study was to classify and characterize the compositional quality of milk
from river buffaloes (Bubalus bubalis) and cows (Bos spp.) in Colombia based on the
fat, protein, and total solid (TS) contents. Using a hierarchical procedure, data on milk
from river buffaloes (n = 7,726) and cows (n = 49,330) were filtered and subjected to
cluster analysis in order to generate three groups: Normal (N), High quality (HQ) and
Poor Quality (PQ). The categorized database was then randomly separated into two sets
(training and validation) and a discriminant analysis was applied. In total, 37.3% of river
buffalo milk samples were classified as N (6.80% fat, 4.34% protein, and 16.80% TS),
13% as HQ (9.41% fat, 4.93% protein, and 19.50% TS), and 43.7% as PQ (3.95% fat,
3.92% protein, and 13.7% TS). In contrast, 41.8% of cow milk samples were classified
as N (3.64% fat, 3.37% protein, 12.42% TS), 41.2% as PQ (2.71% fat, 3.08% protein,
and 10.6% TS), and 16.9% as HQ (5.46% fat, 4.01% protein, and 14.82% TS). The
discriminant models for both river buffalo and cow milk were able to classify milk in the
N and PQ groups with >90% accuracy, and that in the HQ group with >85% accuracy.
