Influence of selected plant associations in pasture vegetation on quantity of milk with focus on spectrum of fatty acids in milk fat
BOHÁČOVÁ, Lucie
The objective of this study was to evaluate the effect of pasture and pasture vegetation composition on the milk yield and milk fat and protein content in the Czech Fleckvieh cattle kept in the less favorable areas (LFA) during the years 2007 ? 2009. These pasture characteristics were observed: pasture quality defined by the chemical composition of herbage groups, determination and rate of dominant grass types, clover types and herbs and the height of pasture vegetation. Next, the fatty acids spectrum in the milk was analyzed and the effect of forage and grain supplements on the milk fat composition was confirmed.

The influence of beef cattle pasture on composition plantation form and developmen non-producing functions of grassland
TRNKOVÁ, Ivana
The influence of beef cattle pasture on the composition of pasture herbage was studied in Šumava region (Kaplice, 550 {--} 850 m a.s.l) from 2005 to 2006. Also was studied the effect of different nanagement of permanent grassland on its composition plantation form and non-producing functions. On the pasture herbage dominated grass and leguminous species. On the fallow land prevailed herb species. On the combined management site (pasture and harvest) was established higher frequency of Taraxacum officinale, Trifolium pratense and Dactylis glomerata

Monitoring moving activity of beef cattle during the year
RUDA, Jan
My work was focused on assesment of moving activity of beef cattle (whole year outdoor lairage) with special aim at outward and inward factors. Experiment was realized in a small privat farm (40ha) in foothills. Breeding animals are crossbreeds of these beef cattle races: charolais, piemontese, aberdeen angus, hereford, gasconne, limusine and czech pied cows.

Use of cattle and sheep breeding for landscape maintenance
HOUŠKOVÁ, Jana
The aim of my thesis was to identify and evaluate the conditions of shared breeding of cattle and sheep reached at pasture rearing as well as to set up the basic behavior of dams in both herds during the pasture period. In the research, there were involved dams (Aberdeen angus) together with 56 ewes (Suffolk runt). Ethological monitoring was done three times during the pasture period (lasting 24 hours) using the method of direct watching (10-minute intervals). Both herds were kept together during the pasture period.

Evaluation the influence of grazing on performance of dairy cows
TOMAN, Michal
This study analyzes the impact on performance of dairy cows grazing in firm, which is located in the LFA. Furthermore, also deals with procedures for management of pastures and grazing alone. The operation, carried out before and during grazing pasture is important in terms of quantity and quality of grass. The results of this study show that the farm was milk production during the grazing season is lower than in winter. Lower milk production was achieved due to increase activity, changes in ration and low quality crop, which was connected with a high burden of pastures. Lower milk production was achieved due to increased activity, changes in ration and low quality crop, which was connected with high grazing load, which was 2.2 DJ. ha-1.

The comparison of sheep nutrition in conventional and ecological conditions
KLÁTIL, Jaroslav
Destination of bachelor work was purchase grass pattern from individual boxes and their successive analysis. Village in who we pursue purchase pasture name Hojovice, which lie in locality district Pelhřimov. We follow herd - 13 sheep, 9 lamb and one ram. Deal with meat race Charolais. Pattern we take away in year 2009 of six boxes about area value one metre square and it ago pasture and after her. Collected sample were weigh in fresh condition and after drying. Right after purchase we are perform analysis material with respect to representation individual grass mate. Completion analytical analysis pasture we obtain information about representation individual material, which were engaged in take away pasture pattern. Analysis was find, that no pattern contain more than 5 % fat. Border content coarse fibre was in all case over 17 %. Also in content NDF collected sample fulfilment optimum gamut from 28 to 32 % NDF. Possible say, that of given purchase and analysis, we are about pasture found, that is not harmful. In spite of solitary pasture be watch herd suffice to covering all energy. Thereby is here possibility extra feeding and dam with drinking water. Good pasture growth we would achieve for example wit sowing, great entry manure and better preparation pasture after fat.

Verification of the effect of rations on goats feed intake and on milk composition
KRÁL, Václav
Goat's milk has many great nutritional properties, which arise from its unique composition. The milk composition is however depending on the composition of the feed diet. The aim of this work is to determine how the diet affects the quantity of milk yield and composition. We also made observations to determine how selected herbs affect the intake of feed rations with goats. The experimental part is divided into three parts. In the first part, we evaluated the impact of selected herbs to income ration with goats. We found that the addition of perennial ryegrass (Lolium perenne) increases the amount of food taken. Conversely, an addition of meadow pea (Lathyrus pratensis) decreases the amount of food intake. In the second part, we tested the ribwort plantain (Plantago lanceolata) effect on the milk composition. We found that an addition of this herb in the ration slightly increases daily milk yield. In the third section we monitored a herd of goats on grassland. We evaluated influence of the composition of pasture vegetation and the addition of oats on milk yield and composition. Our conclusion is that the composition of the pasture had a significant impact not only on the basic components of milk, but also on the representation of individual groups of fatty acids. The adding of oats decreases the influence of grazing.
