Interação ordenhador-vaca e as respostas compor- tamentais, produtivas e econômica dos animais

The objective was to evaluate the influence of the handling of three milkers on the behavior of dairy cows, milking management and animal production. Direct observations were made, continuous and with visual sampling of the milkers behavior and of the cows. The cows participated of the three treatments (milkers), constituting the cross-over experimental design. In the comparative analysis of the human and animal behavior the nonparametric chi-square (c2) test was used. For data on milk production, flight distance and milking time it was applied the variance analysis (ANOVA). In the economic evaluation it was used a descriptive analysis of the production results. It was concluded that the type of handling of the milker influenced milk production, milking time, flight distance and the reaction of the animals.
