Abstract
The research contains experience and results of several years project of sustainable fattening of steers on smalle farms in northeastern regions of Slovenia. In the scope of expected results and aims of the project management of grassland belonging to farmers was analysed with regard to the effect of cattle fattening and grassland maintenance and floral characteristics and biotic diversity. The results show the technology of fattening of steers of the Simental breed on pasture and the comparison with the intensive feeding of bulls of the same breed. Compared are the atained growth parameters, slaughter value, the economic analisys and sale. The aim of the research was to analise the slaughter value of steers in extensive breeding (VE) of different age in the time of castration (<210days, >210 days) and of bulls in intensive breeding (IB). The steers from the extensive breeding were slaughtered at the age of 23 months and bulls at the age of 17 months. All right cold halves were chopped between the 7th and 8th rib into the front and the hind quarter, then the quarters were chopped into individual body parts, which were divided into meat, fat tisue, sinew, bones and in the end everything was weighed. IB had statistically significantly greater body mass at the time of slaughtering in comparison to VE (664 ± 41 kg; 562 ± 46, P < 0.05). The percentage of meat in the cold halves did not statistically significantly (P >0,05) differ between researched groups of animals. The steers in group EV<210 and EV>210 had a lower body mass and in the front and hind quarters no statistically significant differences were found (P < 0,05) in the percentage of meat between researched groups of animals. IB had in the hind quarter statistically significantly (P < 0,05) higher percentage of fat tissue in comparison with EV<210 and EV>210. After EUROP classification 78,5 % of steers were in class R.
