Abstract
The article presents the results of the influence of ration formulations on the productivity, fattening and slaughter characteristics of young bulls of the Simmental breed of cattle at the average level of feeding in the foothills zone of the Carpathian region of Bukovina. The research found that during the summer stall period of the experimental period, the average daily increments of young bulls of the 3rd experimental group amounted to 1117 g, which is 295 g (35.9%) more than in their peers of the control group fed on corn silage in their ration. The results of the research revealed that the bulls of the 2nd experimental group on haylage had daily gains of 992 g, which is 170 g (20,7%) more than control. In the course of research, it was established that the consumption of exchange energy per 1 kg of live weight gain in young bulls of the 3rd experimental group amounted to 96 MJ and 7.9 feed units with a concentration of exchange energy in 1 kg of dry matter of 9.0 MJ, which contributed to the reduction of consumption of dry matter per 100 kg of live weight. In experimental studies, it was found that when feeding the combination of haylage, silage, green feed to animals, the exchange energy is reduced by 30 MJ per 1 kg of gain with a 0.6 kg decrease in energy feed and a 261g reduction in digestible protein
