From the research made on the hygroscopic proprieties of cattle cakes we can say that these absorb vapors from the surrounding atmosphere and the quantity of absorbed vapors is bigger if the relative air humidity is bigger.The oleaginous cattle cakes not only have the ability to absorb water but they can also give it away when surrounding atmosphere humidity goes down. It was shown that at the hydrating and dehydrating process of the cattle cakes in an environment with different relative humidity the balance values of the water content do not coincide - the hysteresis phenomenon. It was shown that cattle cakes with the water content above 11 – 13% kept a longer period of time at relative air humidity above 71% had fungus growth.
