This work does a study on dairy farms in western Parana in order to (1) form an understanding of the social, economic, managerial and technological characteristics present in the property; (2) implement in software an evaluation model of reproductive efficiency of dairy herds and (3) evaluate the acceptance of the producers to the use of software. For it was carried out a descriptive quantitative research with 100 producers of Medianeira, São Miguel do Iguaçu and Serranópolis do Iguaçu, in the western state, seeking, based on statistical analysis, identify, among others, the practice of zoo technical bookkeeping and use of information technology.. The results showed that 90% of manufacturers stated maintain some level of control livestock, however 72% do not evaluate any performance indicator. Among the producers who keeps some livestock control, 87% they do it on paper. On average, 74% of farmers unaware of the profit margin of the activity. Both in cost control, as the livestock control and use of information systems, no significant differences were identified in the behavior of younger producers. The software developed was used for ten months in a dairy property with 150 Holstein animals race, being updated weekly with the reproductive herd events. With the use of the model can analyze 68% of herd animals (100% of the animals at reproductive stage) an extent four times greater than the range obtained by calculation formula calving interval. Training was conducted with two groups of producers of different age groups to evaluate the acceptance of the software with an emphasis on performance expectation constructs, of performance, effort expectancy, attitude for the use, facilitating conditions, self-efficacy and anxiety during use of the system. Regarding the software acceptance, the performance expectations (utility) was the aspect best rated by the producers. The self-efficacy was the appearance of lower perception, showing greater concern for producers with possible difficulties that could face during the use. |
