Výživa dojnic na vybrané farmě
KORECKÁ, Aneta
This bachelor thesis focuses on dairy cow nutrition, housing technology, health and milking levels in pastoral farming in Ireland. A monitoring and evaluation method was chosen to address the issue and evaluate the information found. The monitoring was carried out over a two month period during the period of peak performance of the dairy cows. In the first part of the paper a literature review is presented. On farm, it was found that pasture rearing has an effect on lower dairy cow performan-ce. Nutrition here is provided by grazing or clover silage and pelleted supplementa-ry feed, which supplies balanced nutrients and minerals and vitamins not contained in the crop. The BSC was at a lower value. The main finding was deficiencies in milk hygiene.

Nové trendy ve fázové výživě dojnic
REJZKOVÁ, Martina
When feeding dairy cows, quality forage must be the main ingredient. Prolonged feeding of poor-quality feed can lead to metabolic disorders, weak calves, reduced reproductive capacity, mastitis and other problems. Phase feeding is widely used in dairy cattle nutrition because it is probably the best way to meet the nutrient needs of dairy cows at different stages of lactation, even when standing dry. The basis for respecting the physiological needs of dairy cows is the creation of balanced groups of dairy cows. Nutrition is very important, especially in the transition period of dairy cows. That is to say, the 3 weeks before and 3 weeks after parturition, when dairy cows need the best quality feed and, above all, the greatest nutritional care. These six weeks are crucial for maintaining good health, the production and reproductive efficiency of the dairy cow and the profitability of the entire herd. Modern knowledge guarantees higher milk production and better satisfaction of nutrient requirements. In 2021, after almost 20 years, a new standard, NASEM 2021, was published which gives the expected nutrient recommendation for dairy cattle. Other modern findings include the increasing use of robotic milking parlours with automatic feeding, or the use of vitalimeters or pH probes to monitor digestive pro-cesses and overall animal activity.

Nejčastější nemoci a zdravotní problémy u krav masného skotu
Štůralová, Dagmar
Bachelor thesis is focused on the most common diseases of the beef cattle. The aim of the work was based on the study of literature write up breeding principles of the beef cattle in the Czech Republic and focused on the most common diseases of the beef cattle and diseases prevention especially in cows. In the practical part of the bachelor thesis is process a yearly overview of a particular herd (ecofarm Jany Hůlkové from Staré město u Bruntálu).

Problematika výživy a managementu krav stojících na sucho
Václaviková, Tereza
The bachelor thesis deals with the issue of dry cows. It describes changes and requirements in terms of nutrition, health care and breeding organization, as during these 60 days we can influence childbirth, subsequent lactation and then reproduction. The first part describes actual numbers of cattle in the Czech Republic and in the world. As this work focuses on cattle nutrition, it focuses generally on nutrients and their content in each type of feed. The anatomy of the digestive system and the mammary gland is also mentioned. The conclusion of the thesis deals with the actual spawning and the most common metabolic disorders that arise during the pre-natal period and are manifested after delivery.
