Modelling of technological processes in a dairy cattle herd

The paper presents a model of a technological processes in cattle herd. The concept of developing a model and its implementation was presented in a computer program. It was assumed during construction of a model that the herd consists of particular animals in different age, condition, and which function partially independently from each other. Various events influence a behaviour of model components, including random events which occur with a specific probability. For those units, in the time function detailed rates are calculated. A group of units forms a herd for which group rates are calculated. The developed theoretical model was implemented in the computer program SegaeM which enables calculation of rates which describe a herd and visualization of changes that take place in time.
