Nedělová, Jiřina
The aim of the bachelor thesis is limb diseases in dairy cattle. The first part deals with the anatomy of hoof. The second part describes the characteristics of individual types of diseases, possible factors that may be related to them, diagnostics, preventive steps and treatment. The third part is about the consequences of lameness on milk production and economic impacts. The final part compares Czech Fleckvieh and Holstein cattle and their susceptibility to limb diseases
Vliv zdravotního stavu dojnic na množství, složení a technologické vlastnosti jejich mléka
Justová, Andrea
The aim of this bachelor thesis was evaluate the effect of the health status of dairy cows within quantity composition and technological properties of milk. Milk samples were collected from Bohuňov company. Monitored cows were Czech Fleckvieh cattle. Total number of samples was 20. Monitored properties were: content of protein, content of fat and solids-non-fat. Between technological properties were included: rennet coagulation time, quality of curd, density of milk, milk freezing point, active acidity and titration acidity. In the study were found average values of monitored indicators: protein kontent 3,11 vs. 3,14 g.100g-1; fat content 3,80 vs. 4,06 g.100g-1; lactose content 4,64 vs. 4,69 g.100g-1; solids-non-fat content 8,45 vs. 8,54 g.100g-1; density of milk 1,0287 vs. 1,0289 g.cm-3; freezing point of milk -0,5389 vs. -0,5210 °C; active acidity pH 6,82 vs. 7,17; titratable acidity 6,41 vs. 5,67 SH; rennet coagulation time 208 vs. 213 sec and curd quality class 2,64 vs. 2,60. It was found statistically significant (P < 0,01) diference between aktive acidity of milk. Differences between another monitored parameters were statistically not significant (P > 0,05).
Influence of different housing systems on the health of hooves of dairy cows.
MAKAS, Martin
The present work is focused on evaluating the impact of stable housing on illness and health limbs of cattle. The theoretical part of this thesis focuses on the most common disease of the extremities and the friendly manner of their treatment. In the practical part two measurements made at different locations. Measurements were carried out within one year. They asked a number of diseases and types of diseases. The highest frequency of diseases of the limbs was demonstrated in bezstelivového housing system.
