Oborná, Monika
The aim of the thesis was to evaluate factors influencing the market production of bulls and pigs. For bulls , I focused on the influence of breed , carcass weight and influence of age . In pigs, I watched the effect of carcass weight ( HJUT ) . I started from the measured data that have been gathered under demolition leaves carcasses of bulls and pigs. From these data, I analyzed the impact on bulls breed Holstein cattle , Czech Pied cattle and Holstein crossbreds and Czech Pied cattle. Then I dealt with a market value of pigs and bulls , which I set as the sum of the prices of individual cut-out parts of their carcasses. I assessed the relationship of cutting prices of individual parts of the total sales of carcasses of bulls and pigs. Likewise, I also evaluate the weight of each cut-out portion to the total weight of carcasses of bulls and pigs. Regarding the relationship between výsekovými parts of carcasses of pigs and bulls and total prices for slaughtered uprané body , the highest value of the correlation coefficient in pigs ( r = 0.9958 ) was found in the leg , with the bulls u perk (r = 0.9073 ) .

Růst a jatečná hodnota býků a jalovic českého strakatého plemene skotu
Perničková, Andrea
This work focuses on increase, carcase and slaughter value. It should be mentioned that the growth of cattle is carried out intensively to six months of age. This period is necessary to pay great attention to the animal, as it affects the production period of the individual. Optima nutrition and quality WELFARE ensures that the animal will be in the coming years economically important for its farmers. One of the most important indicators of the carcass dressing percentage, which is the breed of Czech Pied cattle is around 58%. Net increase, however, is an important indicator of meat production are taken into account when breeding. Compared with heifers, bulls higher carcass yield and a lower propensity for fattening. For heifers has been shown that the age at slaughter has a significant impact on their meat production.
