Climatic parameters during the winter housed sheep
ŠKOPEK, Zdeněk
The topic of the bachelor work is concentraded on the assessment of influence of microclimatic parameters during the winter housed sheep. Measure the basic microclimatic parameters monitored in the barn and basic utility properties of the animals. Study group consists of three breeds of sheep, which considers the effect of measured values on their performance. A subsequent comparison of the breeds themselves.

EFFECT OF REARING HEIFERS GRAZING ON MILK YIELD AND FERTILITY
DVOŘÁKOVÁ, Lenka
The agricultural cooperative Opařany 160 pieces were selected for breeding cows anddivided into two groups. Pasture rearing and stable rearing. Which was observed fertility and milk yield. After an overall assessment of the breeding heifers, in 2007 the results of reproduction was worse in pasture system of heifer rearing. By contrast, in the next reporting period in 2008 the grazing system of heifer rearing embody improved results than rearing in stables. After a general evaluation of milk yield, the grazing system of heifer rearing is worse in 2007. In particural the amount of milk in kg and kg of protein. By contrast, in the next reporting period in 2008 the grazing system of heifer rearing reachedimproved results compared stable rearing. And as the number of milked milk in kg, and milk ingredients - % fat, which is in pasture breeding higher in all of KU. The reason of low milk yield results and reproduction charakteristic is especially in poor nutrition and ill-prepared rations, or fed on poor quality components. In the grazing system of rearing the lack of growth in individual animals is due to missing supplementary feed. And for both groups, we should look for causes of poor management and the transfer of young animals to the reproduction and subsequent production should be taken into account the current condition, not age.
