The concept evaluation of nutrition in the agriculture enterprise
HAVELKOVÁ, Jana
This thesis deals with the level of nutrition of dairy cows based on assessing the need for nutrients and energy in relation to the milk yield. Under operating conditions the system of nutrition and feeding is evaluated and also analysis of selected economic indicators of milk production has been conducted. The monitored indicators of nutritional and energy values are within permitted tolerance limit of recommended values.

INFLUENCE BEHAVIOR GRAZING ON DAIRY CATTLE
HŮRSKÁ, Miriam
The work was based on my own watching and the aim of this work was to determine basic vital signs of dairy cows breed in grazing system in the submontane area of South Bohemia. Herd of breeding cows, consisting of the Holstein breed, the Jersey breed and the Czech Pied Cattle crossbred with the Jersey, in quantity of 53 heads. During the year 2010 there were six behavioral watchings namely from June to October. Each watching lasted 24 hours and there was used the method of watching in the group with the time interval of 10 minutes. Cattle vital signs were watched: feed intake-grazing, lying down-resting, standing and movement.

The concept evaluation of dairy cattle nutrition
ROUBÍČKOVÁ, Jana
Bachelor thesis gives a comprehensive overview of the dairy cow nutrition and assesses the system of nutrition and feeding in relation to milk production. The main part is devoted to the basics of dairy cow nutrition, the main nutrient requirements and composition of feed diets. There was assessed composition of feed rations for the year 2010 in working conditions on the School farm Měšice. The recommendations were designed to improve the nutrition level on the farm on the based data.

Influence of different factors for economic parameters of milk production
KLEINOVÁ, Anna
Evaluation of factors, which affect the selected economic indicators of milk production in specific farm, during two years, 2007 and 2008, was the aim of the work. The composition of dietary and its optimalization and feeding technology in stable were evaluated. The contents of basic elements, which affected the realization in every month, were set from the milk production on the basis of analyses. Indicators of reproduction are mentioned then. Evaluation of chosen operational economic indicators of milk production was based on dates about costs and revenues in selected stable. Mixed feeding ration is loaded twice a day and it is compiled in advisory way according to the laboratory analysis results of feed. It was balanced with a moderate abundance of nitrogen substances and solids in production cows and with a deficit of solids in feeding ration of very pregnant non-lactating cows in both years (about 9 %). The fat and protein contents were relatively fixed, with a decline in summer months. The limit for somatic cells was exceeded once (by 3 %) and so the TVC (by 36%) in 2008. Reproduction indicators showed annual improvement with the exception of the intervening period length. There came to reduction in number of coves on the 3rd and later lactations and to decrease of their longevity thus. Their own and purchased feed took share in costs mostly (33,3% in total). In 2007 the loss per litter of sold milk arose but the income moved to positive values after including all revenues. In 2008 a profit per litter of sold mild was reached the milk production reached 3,64% and the total income increased.

Detectionand assessment of noise loading during milking at milking shed.
KŮRKA, Jan
The work deals with the measurement of noise exposure on milking Alfa Laval revoling HBR, Agromilk Pelhřimov dovetail - trigon and milking robot Lely Astronaut A3. When measuring , it was found that the best in terms of noise level measurements published in milking robots with the runing of the feed wagon and measuring worst inside the cell with the milking robots.
