Storing of manure, treated sludge and feed on agricultural land
Svoboda, Pavel ; Wollnerová, Jana ; Kozlovská, Lada ; Klír, Jan
Solid manure of various livestock, compost and, more recently, digestate separates may be deposited on agricultural land under certain conditions. The rules for their imposition are laid down by legislation. The methods of storing treated sludge and voluminous fodder, such as silage and hay, and the operation of feeding grounds on agricultural land are also determined by current legislation. Of the mineral fertilizers, it is possible to deposit on agricultural land only the calcium fertilizer (sugar bowl, fertilizers based on ground limestone). The methodology responds to the changes in legislation in 2020 and 2021, is based, among other things, on agricultural practice and provides comprehensive guidance for storing these materials and operating feeding grounds on agricultural land. It clearly describes all measures aimed at maintaining the quality of the material stored and reducing the risk of environmental pollution, in particular surface water and groundwater. It also recommends the possibility of reclamation after delivery of fertilizers, treated sludge, removal of feed and closure of the feeding grounds. Particular attention shall be paid to measures addressing the potential of sites in vulnerable areas identified under the Nitrates Directive Action Programme. Last but not least, the methodology also includes instructions for selecting a suitable place to store fertilisers, treated sludge and voluminous feed, or a place to feed, using data from the Land Register (LPIS) at the Farmer's Portal.

Faktory ovlivňující stravitelnost organické hmoty objemných krmiv
Faltusová, Adéla
ABSTRACT This bachelor thesis deals with the theme Factors affecting digestibility of organic matter in forages by cattle. The first part is focused on description of basic nutrients contained in feeds and their function in organism. Next there is spoken about ruminal digestion and their parts of digestion system. There are also mentioned traditional forages used in total mixed rations. The second part describes methods using to measure digestibility and the most common factors influencing digestibility of organic matter of feeds.

Fázová výživa dojnic v daném zemědělském podniku
VACEK, Tomáš
In this work, I analyzed phase nutrition dairy cattle practiced on a farm. Furthermore, the work focused on quality of bulky feeds from maize silage, grass-clover silage and field bean silage. Feeding method, composition of rations and production parameters were also evaluated, while taking welfare of the animals into account. For data analysis, a nutrition program was used. Indicators of nutritional values and fermentation characteristics, including microbiological testing of silage feeds (maize silage, grass-clover silage, field bean silage), correspond to a very good standard. For maize silage and grass-clover silage, NDV, ADV and NEL values were shown to be slightly below the national average. When evaluating the nutritional level based on the feed ration optimization, we can conclude that the differences in the monitored nutritional values are within the tolerance limits of the recommended values. The level of nutrition corresponds to the production achieved. Fat and starch content of the feed ration are consistent with the recommended values present in literature.

Komplexní zhodnocení živočišné výroby v zemědělském podniku s ohledem na ekonomiku výživy a odchovu jednotlivých kategorií skotu
JANATA, Martin
In the diploma thesis on the complex evaluation of livestock production in the farm with regard to the nutrition and rearing economy of individual categories of cattle, a theoretical and practical part was elaborated. The work was carried out in the company JINOS - AGRO s.r.o., which has animal production focused on breeding Holstein cattle and milk production. The theoretical part of the thesis deals generally with cattle breeding, economy of cattle breeding, animal welfare, bulky feed and compound feed. In the practical part I evaluated the analysis of large feeds, composition and price of feed ration, rearing of individual groups of cattle, milk yield, milk price development and breeding economy. The data obtained in 2014-2018 were evaluated in the thesis.

Složení a kvalita objemných krmiv ve vztahu k ekonomice výroby mléka
JANATA, Martin
The theoretical and practical part was elaborated in the bachelor work on the composition and quality of bulky feedingstuffs in relation to the milk production economy. I worked at JINOS - AGRO with limited liability company, which is engaged in breeding of Holstein cattle. The theoretical part deals generally with breeding of dairy cattle, welfar of animals, milk, lactation, bulk and nuclear feed. In the practical part, I evaluated the annual yields, the composition of feed rations, the analysis of maize silage, the analysis of clover-grass silage and their influence on the performance of dairy cows. At the end of the work I made an economic evaluation of the milk production in the selected company. The work evaluated the data, which were obtained in 2014 - 2016.

Výživa dojnic v daném zemědělském podniku
PLACKOVÁ, Lenka
This thesis purpose is to evaluate level of nutrition of dairy cows Holstein cattle on the farm. Backround research was made for this topic. Claim of the study is to compare nutritional value of the feed rations with the recommended nutrient requirement ford dairy cattle. The feed ration for cows meet recommended nutrient requirements. Feed rations for the dry-off cows contain high level of nitrogenous compounds. The correction was recommanded. Further, the quality of silage roughage was assessed. Compared milk yield was lower by 615 kg milk/cow/year from the performance of Holstein cattle population in the Czech republic.

Analýza výživy a ekonomických ukazatelů produkce mléka v daném zemědělském podniku
ZEMAN, Ondřej
Under operational conditions the concept of nutrition and efficiency of milk cows (the breed: Holstein Friesian cattle) was assessed in the chosen agricultural enterprise during the years 2015 and 2016, as well as the production of feed for the milk cows and the economical aspect of milk production during the period of decreasing prices of its purchase. The thesis embodies the assessment of the negative impact of a low rainfall total in the locality of monitored enterprise specialising in the production of bulky feed. Because of this fact the feed amount of productive milk cows were changed in 2016. An interannual decrease of milk yield about 1,92 l per 1 peace of kettle and 1 day was recorded on the grounds of the change of feed doses. The decrease in efficiency and consequently the decrease in delivery of market milk to trade in 2016, together with low prices of purchase of milk, had direct influence on a low economical profits in the area of milk production and milk-cows breeding of the monitored enterprise.

Assessment of the Level of Nutrition and its Relationship to Milk Production in Milk Cows
HORKÝ, Jan
In the ZD Kojčice cooperative farm, a stable in Krasíkovice was studied in 2013 and 2014. The farm's production technology and the quality of the ensiled feed, feeding techniques, composition of the feed portions and selected milk production indicators were examined. The economy of milk production was also assessed. The production of ensilage ensured quality feed that was the basis for the milk cows' feed portions. The results show that the feed portions were well balanced in comparison to the recommended nutritional values for milk cows. The average yield in 2014, unlike 2013, decreased by 146 l to 5 960 l per milk cow per year. The costs per feed day were established at 138,2 Kč. The average costs for one liter of milk were 8,75 Kč/l.

Analysis of the operating indicators of milk production
ŠANDERA, Filip
This thesis analyzes the operating characteristics of milk production. The work was developed in agricultural cooperatives of Zemědělské družstvo Podkleťan Křemže. The agricultural holding had been in assessment of dairy cattle nutrition, feeding techniques, quality of roughages, composition of the diet and comparison of economic indicators in dairy production. The quality of roughages was performed by using the fermentation process, and the fodder was subsequently classified into different classes. The composition of the diet was assessed with recommended values depending on the energy need and nutrient requirements. The reproductive performance was compared with data on total population. The economic factors were assessed in connection with yield and cost of farming.
