Vliv ročního období na tržní produkci sýrárny zpracovávající kravské mléko
Doleželová, Petra
In this graduation thesis, I have investigated the influence of the season on market production dairies. he aim of the work is divided into the following sub-goals: the influence of season on the reception of milk to the dairy, protein content in milk, yield milk and ferment aktivity. The dairy, which I described handles mainly on cow's milk for cheese Niva, curd and cream. Milk came from 8 surrounding farms, which breeding only the Czech Pied cattle. Monitoring was carried out for a period of one year starting from November 2014 to October 2015. I found that most milk was bought from suppliers in summer and least in the winter months. The milk protein content was highest in winter and lowest in summer. While the amount of milk purchased was constant, the price per liter of milk has a tendency of decreasing (from CZK 9.05 to 7.48), and thus the costs of buying milk lower, while revenues are constant. Milk yield ranged from 7.43 liters of milk / kg of cheese (in October) to 8.42 l / kg cheese (in February).

Vyhodnocení úrovně mléčné užitkovosti v chovu koz na farmě Bílsko
MAJTÁNOVÁ, Lenka
The aim of the thesis is to evaluate milk production levels of goats on the ecological farm Bílsko. The thesis analysed selected factors influencing goat milk production, especially the quality and quantity of feed and the age composition of herds. In order to assess the milk production, a data set from the primary breeding records from 2012 to 2016 was used. The milk production on the farm increased at that time. The milk production reached 417 kg in 2012 and then 437 kg in 2013, 555 kg in 2014, 633 kg in 2015 and 648 kg in 2016. The thesis also evaluates the content of milk constituents, that is fat, protein and lactose. In 2012 the milk consisted of 3.88% fat, 13% protein and 4.4% lactose. In 2013 it contained 3.29% fat, 3.23% protein and 4.4% lactose. In 2014 the milk contained 3.26% fat, 3.17% protein and 4.4% lactose. In 2015 the fat content decreased to 2.79% and the protein content decreased to 2.98% while lactose reached 4.5%. In 2016 the fat content again decreased to 2.53% and the protein content decreased to 2.83% while lactose increased to 4.71%. The milk production results in the selected herd were compared with national data. Based on the obtained data, the conclusion provides measures that would increase the milk production. These include mainly reducing the number of goats, removing old goats from breeding and improving feed rations.
