Resumo

The methodical recommendation on the process designing of the system of removal and preparation for use of manure and excrement is to assume the daily output of cow excrement equal to 55 kg (feces 35 kg, urine 20 kg), not considering the productivity and live weight of the animal. The mathematical model for definition of the daily output of excrement is offered in the paper considering the daily consumption of water and dry substance by the cow, live weight, and productivity. The excrement output according to the offered mathematical model from the cow with the live weight 400–700 kg and productivity 4000–10000 kg of milk per year varies within 51–107 kg per day.
