| Abstract | |
The purposes of this work were to relate satisfaction of employees\' human needs with milk quality indicators, to evaluate technical knowledge of milkers and producers or managers, to observe milking practices conducted, relating them to milk quality indicators and to verify adoption of dairy farms management tools, according to MDA system, of Clínica do Leite - ESALQ/USP. In order to achieving these goals, 74 dairy farms located in states of São Paulo, Minas Gerais and Rio de Janeiro participated of this work. These dairy farms were divided in two groups, from total bacterial count (TBC) average, being the group with high TBC with average greater than 200,000 cfu/ml and the group with low TBC with average minor than 50,000 cfu/ml. Visits to these farms were accomplished during half day, being these constituted of milking routine observation, application of questionnaires to milkers about satisfaction of human needs, according to Maslow and technical knowledge and application of questionnaire to producers or managers about aspects related to farms management, according to MDA system. Statistical analyses were performed by descriptive statistics and also by regression trees methodology, relating questions with TBC and somatic cell count (SCC). The TBC average of dairy farms with high TBC was 330,113 cfu/ml (± 143,865 cfu/ml), and of those with low TBC was 49,126 cfu/ml (± 36,704 cfu/ml). The averages of SCC were: 908,473 cells/ml (± 463,992 cells/ml) to dairy farms with high TBC and 605,728 cells/ml (± 282,885 cells/ml) to dairy farms with low TBC. Both groups of milkers and producers or managers showed a satisfactory knowledge about milking routine, but a little percentage of both groups knew the concepts related to milk quality. Nevertheless, knowledge about mastitis was greater to milkers and producers or managers of dairy farms with low TBC. Regarding human needs satisfaction, all needs tended to be more satisfied to milkers of dairy farms with low TBC, except for physiological needs. The same scenario was observed to administrative management of dairy farms with low TBC, being the adoption of management tools, like basic policy, routine management, operational protocols and human resource, tended to be greater at these farms. Besides, milking routine recommended practices were more and better conducted by dairy farms with low TBC, just like equipment cleaning. In this way, it can be observed that aspects related to technical knowledge, employees commitment, achieved through satisfaction of human needs, adoption of administrative management tools and milking were interfering at milk quality. Despite dairy farms with low TBC showed better results at these areas, there is a possibility to improve the product quality, through investment in all related areas of these work. (AU) | |
