Sažetak
We analyzed the influence of fattening process upon alternations of body dimensions, trijas and blood sedimentation of thirty simenthaler bulls during their period of fattening. At the very beginning of the fattening period bulls belonged to medium condition category and by the end of fattening period they were in very good condition category. Bulls were five months old when the research commenced and they were eleven months old when the reserch was terminated. All body dimensions were measured by Litin stick except for breast circuit, metacarpus circuit and body weight. Bulls were tied and remained at the same place during their fattening period staying in ordinary cow-shed made of brick. All height measures increased at the relatively equal pace during the fattening period. Withers height increased most and back height increased the least. Tenderness of the back appeared to be most prominent at the end of fattening period.Concerning length dimensions, body length developed quickest, head length slowest. As far as body width of bulls is considered the fastest growth was recorded concerning pelvis breadth; head front breadth increased the least. Breast depth was most notable at the point of bulls entering the category of very good condition during their fattening process. Brest circuit increase, as well as metacarups circuit and body weighat increase, were considerably quicker during the period of bulls going from medium condition category to good condition category then from the middle to the end of fattening period. Breathing and body temperature remainer almost the same during the fattening period and the process of fattening itself did not influence them. Blood sedimentation of bulls remained approximately the same during periods of medium and good condition state. Blood sedimentation increased constantly after bulls reacshed very good condition state, that is, it increased due to intensive feeding and richer accumulation of fat tissue of simenthaler bulls.
