This research was conducted in Guayacán, Puembo and Envidia of La Maná Canton naturally located in the western region of the outer foothills of the Andes, in the province of Cotopaxi Enclosures.

Research and lasted 84 days in total and for samples sterilized plastic containers with a thermos to keep them cold for easy transport to the laboratory were used. In the different properties that could distinguish averages presented in pH 6.5, an acidity ranging from 13.50 to 14.90 ° Dornic, a density of 1.03 g / cm3 and fat between 3.4 to 3 , 8%, protein small and medium farms had an average of 1.87 and 2.41% below the average established which is 2.90% as opposed to large farms that had a near 2 average, 79%. Aerobic count and Escherichia coli Mesophiles different ranches Canton La Mana meet specific requirements that are to quantities below the maximum level is 1500000 CFU / cm3. As for somatic cell count only large farms had an average of 386,621.59 CFU / cm3 As Recommendation should encourage prevention and care of mastitis and common infections because they are a factor in milk production. So you could check the cattle at least 2 times a year to ensure their body condition and guarantee the quality of the product itself.
