RESUMO:

The mastitis control is still a bottleneck for milk producers due to several linked factors
such as microbial load, comfort and envinronment of animals permanence. Measures
as the ten points program were developed to combat the several factors that cause the
disease. However, the failure of some farms is still observed even with implementing
such programs. In view of this, some studies point to the human factor as decisive in
obtaining quality milk. The work objective was investigated the influence of human
factor in the quality milk from midwest region of Minas Gerais farms. The work was
developed in Pará de Minas and in adjacent cities, on farms that supply milk to the
CCPR (Cooperativa Central dos Produtores Rurais). Was adopted the method of
convenience sampling by selecting an acessible sample population. Were analyzed 45
farms separated into three groups: farms with somatic cell counts (SCCs) below
250,000 cells/mL, between 250,000 and 700,000 cells/mL and above 700,000 cells/mL
in the last year. The data of SCCs values were provided by CCPR which carriers out
monthly control of the quality of milk of all its producers. To evaluating the human
factor a questionnaire was applied to the farm owners and another to milkers. A third
questionnaire provided by Clínica do Leite researches was applied for both. The
questionnaire applying was realized by visit in loco on the farms and individually. The
difference on the frequency of responses in the producer and milker questionnaires to
each classification was evaluated by chi-square test with maximum error rate of 5 %
probability. For the questionnaire provided by Clínica do Leite, a dynamic table was
used to compare the responses of milkers and producers. There was no statistical
difference between the milker’s responses to the quistionnaires, however, there were
differences in some specific questions among the producer’s responses. The Clínica
do Leite questionnaire also showed no statistical difference, but it was possible to
compare the expectations of producers and milkers on the farms of different groups.
We concluded that the human factor, specifically, the attitudes and behaviors of milk
producers, contributes to the results of milk quality in farms in the central-west region
of Minas Gerais.
