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.

Využití probiotických a fytobiotických krmných aditiv ve výživě telat
WENDL, Denis
The bachelor thesis describes the antenatal period, delivery, treatment of the cow and calf after birth. Most attention is paid to nutrition and rearing of calves. The topic deals with the nutrition of the calf from the first days of life, as this period is the most important for the transmission of good immunity.The next period is dairy nutrition, which is associated with a good development of the digestive system, using starter feeds. Other chapters cover the basics of zoohygiene, disease agents and the overall nutrition of calves using feed additives such as probiotics and phytobiotics

Využití krmných aditiv ve výživě jalovic
DVOŘÁK, Adam
Feed additives are a commodity that has been increasingly talked about in recent years. These substances have a number of positive properties and potential for improving digestion and animal health. They increase the quality and quantity of feed received. These products can also be included in the feed ration of heifers. The aim of the bachelor's thesis is to develop a literary study dealing with the nutrition of heifers with a focus on the use of feed additives in the feed ration.
