Mléčná užitkovost kozy bílé krátkosrsté a hnědé krátkosrsté ve vybraném chovu
KRAMEŠOVÁ, Jaroslava
Goats have recently become popular for breeding. They are breeding mainly for meat and milk. The aim of this study was to evaluate the performance of goats in gene reserves in the Czech Republic. The average milk yield for years the 2020 to 2022 for a white shorthaired goat is 296,0 kg per standardized lactation and for brown shorthaired goats is 270,1 kg. The average fat content of milk for white shorthaired goats is 4,34 % and for brown shorthaired goats is 4,27 % in the monitored period. The protein content of a white shorthaired goat is 2,90 % and for brown shorthaired goat is similar (2,89 %). The last monitored substance was lactose. The average content lactose in milk for a white shorthaired goat is 4,29 % and for brown shorthaired goat is 4,24 %. Results show below the average milk yield but milk fat content was higher than average. This milk is better for example to make a cheese. The milk yield and the content of the individual components are genetically influenced. They can also be influenced by stress, nutrition, and other factors.

Zhodnocení mléčné užitkovosti kozy bílé krátkosrsté ve vybraném chovu
ČECHOVÁ, Pavla
Goats in the Czech Republic are currently bred for the production of milk and meat. Goat milk is a valuable food and therefore there is a growing interest in it. The aim of this work was to evaluate the milk yield in the White Shorthair Goat breed in the chosen breeding station. This work was focused on milk yield, the amount of fat, protein and lactose in goat milk. The data obtained from the milk yield control were compared with national averages and with the literature. The average milk yield on the selected farm was higher in comparison with the national average values of milk yield for the White Shorthair Goat. Furthermore, obvious differences in fat and protein content were found, while no differences were found in lactose content. Data from the milk yield control from 2016 - 2018 were used for evaluation. All obtained data were processeed in Microsoft Excel

Složení kolostra a mléka ve vztahu k biochemickému profilu krve u koz
Korbélyiová, Lenka
The main topic of this thesis was to study changes of goat colostrum and milk during lactation and the context of their composition and biochemical parameters of goat blood. The literature review summarizes the basic information about goat milk, its production, factors which determine its quality and how nutrition affects the composition of goat's milk. The practical part of this work is devoted to the evaluation of the goat colostrum and milk composition and its comparison to the lactation phase and to the biochemical tests of the blood of these animals. For the purpose of this study, 15 white shorthair dairy goats were monitored for 30 days, colostrum and milk samples were collected nine times and blood was collected three times for biochemical profile evaluation. Fat, protein, lactose, fat free solids, somatic cell counts and electrical conductivity were determined in colostrum and milk samples. These results were compared and found similar with the values from other studies and a similar progress of lactation was observed. Furthermore, the correlation coefficients between colostrum / milk parameters and the values of biochemical examination of goat blood were calculated. The results of interrelationships of blood biochemical parameters and colostrum / milk composition do not confirm the unequivocal relationship between biochemical blood parameters and colostrum / milk composition. Given the large number of factors that may affect both colostrum and milk composition and the concentration of biochemical parameters of blood plasma, further research focused on the relationship between these indicators in dairy goats would be appropriate.

Vyhodnocení úrovně reprodukce, odchovu a mléčné užitkovosti koz
Julina, Šimon
The aim of the diploma thesis was to evaluate the level of reproduction and kid rearing of the selected goat herd and to evaluate the milk production of the herd. The practical part of the thesis evaluates the results achieved on a selected family farm with goat breeding. In the period 2015-2017, the total dairy yield of the herd was recorded. In 2017, the level of reproduction and kid rearing was also monitored. The detected values are then compared to the average data achieved in performance testing in the given years and the results of foreign studies on a similar topic. Herd fertility was rather average and reached 136 %. The percentage of kids reared by 1 goat was 112 %. Dairy production per 1 goat for lactation was rather below average, it was 437 kg in 2015, 414,4 kg in 2016, and 347,2 kg in 2017. The percentage of fat, protein and lactose content was comparable to performance testing values. In the end of the thesis several modifications are suggested to improve the organisation of goat breeding on the farm.

Vlivy působící na mléčnou užitkovost koz
LEDREROVÁ, Jindřiška
The purpose of this work was to evaluate the milking effectivness of goats from a selected breeding. The evaluation was executed in family farm Výrov, that is focusing on breeding the Czech Shorthair breed. The The evaluation took place from 2014 to 2016. It analyses chosen influences that affect effectivness with focus on age of the animal, size, milking amounts and fat and protein concentrations in milk. Analysed data were taken from breeding records and compared to the data from Czech farms. MIlking effectivness was 909 kg in 201, in 2015 it was 1015 kg and in 2016 it rose to 1130 kg of milk per lactation. Mean fat percentage dropped from 5,42 % in 2014 to 5,06 % in 2016. Mean protein percentage dropped from 2,75% in 2014 to 2,71% in 2016. The protein percentage rises at the end of lactation cycle in August, September and October. The breed maintains a very high fertility rate at 238,1 % in the long term.

Vyhodnocení mléčné užitkovosti vybraného chovu koz
KRAPKOVÁ, Adéla
The aim of this diploma thesis is to asses the effect of various factors on the milk production and its content in regard to goat's milk in the years 2015 to 2017. The evaluation was conducted on goat farm Richmond Stars in Chotětov. The farm currently accommodates 31 goats of the white shorthaired breed. They are still opting for the one rectangular space solution. The feeds consist of bulk fodder, silage, hay and grass (pasture during summer). The feed composure is the same throughout the whole year. The water supply system consists of water containers with manual refill. The goats are divided into groups based on their age. Milking takes place twice a day. The data on milk production was processed using Microsoft Excel and Statistica. When comparing the overall milk productivity with the average of Czech Republic, there were statistically significant differences found in the fat content in the year 2016, in the protein content in years 2015, 2016 and 2017, in the lactose content in the year 2015. In all cases, the Richmond Stars farm was the one with better score. Other results were evaluated as inconclusive and therefore no statistically significant difference was found. When considering the impact of the goat's age on the milk productivity and the goat's milk content, there was a statistically conclusive impact in the productivity (milking) itself as well as in the fat content. When observing the impact of the father-line on the productivity level and the milk content, there was a statistically conclusive result only in the fat content. When evaluating the impact of the period of birth on the milk productivity and milk content, there was a statistically conclusive impact on the fat and lactose content. All other results, specifically the productivity (milking), were evaluated as inconclusive and therefore were not statistically significant for the purpose of evaluation of the milk productivity characteristics.
