RESEARCH REGARDING GREEN MASS CONSUMABILITY OF NATURAL GRASS LANDS AND PRODUCTIVE EFFECT IN FATTENING YOUNG CATTLE

This experiment, aims to establish the relationships between chemical composition of volume forages, their consumability and the productive effect in fattening young cattle of Brown breed. The productive effect of volume forages along with concentrates administered in the food young cattle, is influenced in the most part by ingestion capacity, which varies depending of many factors. Thus, was organized three experimental groups: E1, E2 and E3 of eight heads young cattle of Brown breed. The First one experimental group received green mass which coming from a natural grass lands, consisting of a mixture of graminaceous that dominate Lolium perene and vegetable, all harvested from the third pastoral cycle, given as the only component of the ration. The second experimental group received green mass ad libitum and two kg concentrates for each head every day, keeping the rations before established. The third experimental group received green mass ad libitum and three kg concentrates for each head every day.The results of this experiment showed that:the green mass consumability was different from quantitative point of view (ingestion capacity per head per day), it have been in close interdependence with nutritive value, the presence or absence of the other types of fodder in ration. In the same time there is a other factors related to the body specifity, such as, the age, the body weight, the capacity of the rumen etc.
