This study was carried out in Junín Region, specifically the districts of Concepción and Nueve de Julio -Concepción, Matatahuasi - Matahuasi and Apata – Jauja, with the participation of 4 milk collection companies and 20 dairy farmers with approximately 208 cows, of which 156 were producing milk with an average production of 10 liters / cow / day. The study included different types of dairy cattle (Simental, Holstein, Brown Swiss and criollas). The objectives were: 1) to identify the dairy farmer’s management practices in the milking process, 2) the type of milking procedure (manual or mechanized), and their influence on the composition, microbiology and hygienic quality of their milk; 3) the difference in composition and quality of milk collected by the owner of the plant and that brought in by external collectors to the processing plants, and the process of milk deterioration over time, and 4) develop guidelines for good farming practices. Results show that none of the individual farmers had a routine milking protocol; 6 farmers had mechanized milking and 14 manual milking. Methods included a statistical linear model for a factor in the comparison between groups and nonparametric tests as per the number of groups to be compared (Kruskal-Wallis test and Mann-Whitney test). With regards to milk composition, the following were found: Acidity (D|) 15.67, density (g / cm3), Fat (%) 3.71, SNG (%) 8.19, ST (%) 11.90, protein (%) 3.47, lactose 4.15; with respect to TRAM 359 (mt) and in CCS (thousands) 445. As for quality of the milk brought into the processing centers, there were significant differences in temperature at time of arrival, methyl blue reduction and number of somatic cells. Where deterioration is concerned (including the three variables above), only the time of methyl blue reduction showed significant differences. A set of guidelines for good farming practices were developed to improve milk quality and management
