Redukce metanu u přežvýkavců pomocí výživy
Pávišová, Aneta
The bachelor thesis "Methane reduction in ruminants by means of nutrition", provides a comprehensive overview of the ways in which methane production in ruminants can be reduced within the limits of possibility. The thesis discusses the addition of feed additives to the ration, the manipulation of feed components in the ration and the influence of feeding techniques. Finally, it describes alternative methods of methane reduction, such as the use of vaccines in ruminant breeding or the use of genetic selection. Livestock are responsible for up to 18% of anthropogenic greenhouse gas emissions and this figure is estimated to increase further. At the same time, the formation of methane in the rumen results in a loss of energy from feed of up to 12 %. The use of feed additives in the ration rather than ration modification alone appears to be effective. The type of animal, housing management and individuality of the animals are very important. It is important to design and research both new and existing measures in order to establish clear feeding practices and reduce the economic losses of the farm.
