Selection of broiler on high growth rate affected significant decreasing of fattening period and gain feed ratio. However, it caused disproportion between ingreasing of body weight and skeleton. Because of that, the skeleton was lagging behind the body weight. This situation could lead to break of bones and significant economical loss. Vitamin and trace mineral additives which are responsible for appropriate bone mineralisation, were removed in this experiment. Due to these resons, the broiler tibia strength was researched. The removing of vitamin and trace mineral additives from broiler diet last 12 and 8 had negative effect on the broiler bone strenght. The four day removing of these additives did not cause the negative effect on bone strenght, which should be the subject of new researches.
