Caracterización y mejora de la calidad higiénico sanitaria de la leche en los diferentes sistemas productivos bovina en la parroquia Guasaganda.

This research was conducted in Guasaganda Parish, which is located 30 km north of La Maná Canton Cotopaxi Province, covering an area of 398 square km. It is located at an altitude of 580 meters, with a temperature of 18-24 ° C between geographical coordinates of 0 ° 47 '46 "south latitude and 79 ° 08' 45" west longitude. It was to identify sanitary hygienic characteristics of milk and systems of dairy production, establish quality physicochemical and microbiological analysis of it and realize the economic analysis of farms producing milk, which consisted of 18 randomly farms, of different systems of dairy production on farms (small, medium and large) of Guasaganda Parish. In the present investigation Design will be used completely randomized (CRD) with 6 replicates per treatment to determine differences between treatment means for each period, the multiple range test of Tukey (P ≤ 0.05) was applied. Which were evaluated for pH, acid, fat, total solids, density, ash, protein, somatic cells in physico-chemical analysis and mesophilic aerobic bacteria, E. Coli in microbiological analysis. Analysis and interpretation of the results it is concluded that: That the system dairy production such as extensive, intensive and mixed in small herds, apply a system of extensive production medium and large applied a production system mixed so the grazing alone does not cover the needs of dairy cattle lack of knowledge of good milking practices and low technological level of farms producing milk are the main causes of contamination of milk produced, As for microbiological analysis count of bacteria in somatic cells, mesophilic aerobic and E. coli in the three treatments are below the maximum set by the INEN table 9: 2012. The cost of production in small farms is 0.37 ctv dollar and costs 0.08 ctv benefit dollar per kg of milk that serves as support for the family and keeping livestock. In medium farms production cost is 0.33 dollar ctv a cost benefit ctv 0.19 dollar per kg milk hand allowing particular work. In large herds
