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.
