Conteúdo: 	An intelligent system has been developed that uses multiple indicators of cow activity and physical response as input to a neural net. The resultant interpretation yields a prediction of when to breed the cow to achieve pregnancy and the ensuing milking period. A computer driven instrumentation system users sonar to measure the location of the animals in a stall in the dairy barn. Interpretation of the cow movements produces an activity quotient that indicates estrus. Daily blood progesterone sampling of up to 17 cows during the research period provided the confirmation of the estrus cycle of the dairy cow. The non-invasive computer assisted system involves minimal labor to make time of breeding decisions in stanchion dairy barns where detecting estrus has been very difficult and labor intensive.
