A dairy farming system for use in a livestock building environment for dairy animals and including at least one dairy animals-related device to carry out a dairy animals-related action, in particular on one or more of the dairy animals, and a controller to control the dairy farming system, with a communication system comprising a first communication device, and a second communication device wearable by a person. The dairy farming system is configured to define a parameter value of a parameter relating to the condition of the person, and the controller is configured to generate an information message and make, on the second communication device, the message cognizable to the person depending on the defined parameter. Since the dairy farming system can assess the condition of the receiving person, the system can make a choice in the sending and/or making cognizable the information to the person, so that it can be better guaranteed that the information to be sent will be effectively processed, and is not disregarded or incorrectly processed because the person is, for example, suffering from a high level of stress.
