The performance and fertility of pasture reared Holstein heifers
NEJEDLÁ, Alice
The aim of this thesis was to evaluate the parameters of the milk performance, reproduction indicators and health of Holstein cows that were raised on pasture. The data were obtained from 50 pure bred animals and its crossbreeds which had been grazed and the control group which was represented by 20 heifer which had been reared in stable. The evaluation of parameters was set on the first standardized lactation in the range of 240 to 305 days. The first lactation milk performance traits were: quantity of milk (kg), quantity and content of fat (kg; %), quantity and content of protein (kg; %). The fertility traits were: length of service period (days), insemination interval (days), age at first calving (days).
Energy use of phytomass in the South Bohemia Region
NEJEDLÁ, Alice
This bachelor thesis focuses on energetic use of phytomass in the Southern Bohemia. There was identified real and potential production of biomass in the Czech Republic and in the Southern Bohemia. According to the information acquired from literature, internet and questionnairy research there was identified volume of use of energetic sources and biomass deliberately cultivated in Southern Bohemia for energetic use. The results of this research show that Czech Republic meets the commitment to cover 6% of energetic consumption by renewable energy source ? it even reached 8%. Southern Bohemia produces 4,5% of all renewable energy sources of the Czech republic. The research shows that there is a lack of biomass in the Czech Republic, that is why it must be produced by growing energy crops (PEP) and fast growing woods (RRD). Energy crops produces in the Czech Republic are: Sorrel Feed, Miscanthus Chinese, Knotweed, Reed Canary Grass, Hemp, Sorghum. As fast growing woods there are willows and poplars recommended. The most of the renewable energy sources in Southern Bohemia is represented by biomass and its combustion. Its potential is huge, mostly the waste of wood processing ? sawdust and wooden chips, is the most used fuel. Energetic use of biomass has a good perspective in Southern Bohemia. There is still unused waste from logging and straw in agricultural production. There is still hidden potential in growing energy crops and fast growing woods. The development is defended especially by economic reasons and state financial support.
