Vyhodnocení růstové schopnosti a jatečné hodnoty býků českého strakatého plemene skotu

The objective of this study was to monitor the growing intensity of the bulls of Czech Fleckvieh with subsequent evaluation of the quality of the carcass in a selected company in the Vysočina. There have been monitoring in the years 2011-2014 these indicators and inter-annual results: bulls housed an average of 293 pieces, increases amounted to an average of 35580,76 kilograms in total, concentrated feed consumption averaged 2,66 kg per ks.den-1, concentrated feed consumption was of average 94667 kg total, average growth per day feeding 0,99 kg, feed consumption per kg of growth reached an average of 2,89 kg, an average of 94 bulls were sent to slaughter, with a total weight of 58,987 kg and the average slaughter weight amounted to 633,2 kg. Finally, evaluate the effect weight was 266 bulls for carcass quality, the average slaughter weight amounted to 715,4 kg. As an indicator was chosen carcase weight, which amounted an average of 401,9 kg. Furthermore, the average daily gain these monitored bulls amounted 0,985 kg, and the average age at slaughter was 23 months. Another indicator of the level of conformation, which assigned a point value system amounted 3,42. The degree of fat cover, which in the allotted scoring average value amounted 2,12. Average entry into the class SEUROP these bulls was U2. To evaluate the influence of slaughter weight of bulls on selected indicators of meat production was observed positive effect of increasing slaughter weight of bulls for carcass weight and conformation level carcasses. Fat cover of carcases different slaughter weights were not negatively affected. An interesting finding was a higher average daily gain of bulls slaughtered at higher weights. This indicates good genetic potential of animals on its suitability for fattening to slaughter weight higher, while achieving higher quality carcass (SEUROP favorable classification system and the higher financial profit for slaughter animal). In the company will still need to optimize ration, mainly to enhance the quality roughage feed
