The low quality of milk obtained of family farms needs information and technologies that provide this improvement in the quality of raw material. Given the large number of family farmers in the country, which do not have access to information on production of quality milk, it becomes necessary to develop and implement procedures for qualification in these farms. Therefore, this study uses the methodology of Reference Unit, able to inform and train farmers on the minimum requirements for the production of quality milk. The methodology to evaluate the influence of the qualification process for improving the quality of milk in small farms, the study was divided into three stages: the first was the selection of reference units and its characterization through a questionnaire and analysis of the quality of milk, as fat, protein, lactose, total bacterial count and Somatic Cell Count; and the second step was the implementation of the Reference Units in farms and the transmission of information and technologies through training hygienic -sanitary, and final evaluation of the qualification process through the analysis of indicators of quality of milk, made during the 12 month study. The statistical evaluation of results was done using analysis of variance (ANOVA), identification of outiliers and Tukey's test, using the program Minitab 16. As a result of this evaluation, the values of fat, protein and lactose in milk samples resulted within the limits established by law. And as in other studies, the values of fat were the most varied in relation to other components of milk. With regard to the values of somatic cell count, 29% of values were above the limits established by legislation, ranging from 1 to 27.47 x105 CS / mL, and the values of total bacterial count, 3.5% of samples are within the limits throughout the study. Both parameters of milk quality (SCC and CBT) did not change significantly over the months of study, this can be explained by other factors that influenced the research, how the season. Family farmers absorbed all the information passed in higienic sanitary training and have implemented all management techniques to prevent and detect disease in the herd, this was checked with a questionnaire to producers. Therefore, it is worth mentioning, which is still lacking an organizational culture that provides using participatory methods, the advancement of knowledge for local development. |
