Abstract:

In my diploma thesis, I have been observing the influence of the milk yield on the exterior changes of cows of the Czech Fleckfieh breed. The monitoring was carried out in August 2017 at PROAGRO Radešínská Svratka a.s. in a group of 83 cows on the second and third lactations for which an exterior evaluation of linear description was performed at the first lactation. The cows were subsequently evaluated by a linear description on the currently ongoing lactation. The whole set was then divided into three groups according to the milk yield values for cows with low, medium and high milk yields. Th

Abstract:

The aim of this study was to analyze locomotive score of dairy cows with movement disorder and its influence on milk production. For the experiment were chosen Czech fleckvieh dairy cows in company GenAgro Říčany a. s. in season from June to December 2015. The monitoring was conducted a day after the milk recording. Analyzed parameters of milk recording were milk yield (kg of milk), protein content (%), fat (%) amount of somatic cells (thousands/ml), lactose (%) and content of urea (%). Cows were evaluated according to the locomotive rating scale from 1 (cow with no movement disorder) to 5 (co

Abstract:

In my work I deal with analysis of the impact of selected parameters of the breeding environment to live weight of cows. Observations took place in the company Golden Farm Ltd. in the village Štětovice with 60 pieces of Czech Pied breed. Among the parameters ana-lyzed were breeding environment milk yields, order and stage of lactation. Attention was dowry-Vána stage of pregnancy and the effect of the calendar month of the year on the live weight of cows. Data were collected during one year starting from September 2014 to October 2015. The obtained results were obvious influences

Abstract:

In thesis are comparing two cattle farms in area around Svratka, focussed on dairy cows of Czech Fleckvieh cattle. One is conventional farm and other is organic farm. Thesis is focused mainly on analysis of differences in volume of milk and its composition. Quantity of milk was monitored in monthly intervals for period of one year. Apart from milk quantity we observed contents of fat, protein and lactose. Number and day of lactation was also taken into account. Attention was given to composition of daily ration for dairy cows on organic farm, and we also monitored number of somatic cells and s

The diploma thesis "Selected factors on milk utility of Czech Fleckvieh dairy cows" deals with certains effects on selected cattle herd, which are detected from milk utility control. The author compares dairy cows within first and third lactations in all cases. Overview of used literature is selected into specific chapters, in first part the Czech Fleckvieh is defined with its history, characteristics, related breeds and breed utility. Another comprehensive chapter is devoted to milk utility, lactation and selected factors on animal utility. Last part of literature overview is devoted to

Abstract:

The set includes 1782 heads of culling Czech fleckvieh cattle eliminated from 1 January 2012 to 1 September 2015. Influences on the first calving age, calving interval and lifetime milk yield were detected for data in the set. The following items were integrated among selected lifetime milk yield influences : genotype, herd, first calving age and first calving month. It was also tested whether the age of the first calving of milking cows is influenced by genotype and a herd. The last tested hypothesis was related to the influence of genotype and a herd on the length of the carving interval. Th

Abstract:

The aim of this thesis is to evaluate chosen influences on the extent of reproduction of randomly chosen milk cows that are bred in the same conditions. The chosen influences such as breed, age of the first calving, time of year of calving and level of yield were observed within breeds of Czech Fleckvieh and Holstein cattle. Evaluation was carried out in ZOD "Podhradí" Choustník company, specifically in Budislav farm. 191 cows were chosen for the basic sample. 95 of them were Holstein cattle and 96 were Czech mottled cattle. Chosen influences were evaluated according to data gained from the se
