Resumen
Descripción
The aim of this study was to determine the compositional quality of local goat milk from Comarca Lagunera, Mexico. Variables measured were: fat, protein, lactose, non-fat solids and total solids. Three hundred and fifty lactating local goats were randomly taken from 6 f locks. The goats were managed extensively and fed with native vegetation, although the diet was occasionally supplemented with agricultural residues. Farms were visited monthly from February to September 2013 to be present at milking time. Milk was manually homogenized to take samples which were later examined with a MilkoScope Expert Automatic® analyzer. Data were analyzed with SAS V 9.0 software to characterize the milk component curves as a function of time. Overall means for milk components were: fat 4.13 % ± 0.66, protein 3.32 % ± 0.29, lactose 4.95 % ± 0.43, non-fat solids 7.41 % ± 0.67 and total solids 13.14 % ± 1.7. There were significant differences (P<0.01) between months for protein, lactose, non-fat solids and total solids.
