Quality assessment of bovine milk (Bos taurus) in the Community of Mazo Cruz La Paz-Bolivia

Abstract

The milk quality depend of a good feeding, good health and adequate management. The aim of this research was to evaluate the physical, chemical and sanitary characteristics of bovine milk from ASOPROLEA M.C. it was determinated 17.44±2.06 and 16.22±4.22 of oDornic, 1.025±0.002 and 1.030 to 1.034 g/cm3 of density, 6.55±0.55 and 6.71±0.36 of pH, 10.25±0.3 and 9.80±0.54 % of total solids, 3.65±0.56 and 3.55±0.60 % of fat, 2.82±0.11 and 2.66±0.21 % of protein, 4.05±0.4 and 3.90±0.35% of lactose, 0.75±0.05 and 0.73±0.15% of minerals for milkcan and milktank respectively. About TRAM 48.2 % of samples are reducted in less than 2 h and 51.8 % of milk samples are reducted in more than 3 h. The high problem seems to be the microbial contamination in milkcans and in the milktank of this community, it could be necessary to review the milktank.
