Prevence a léčba mastitid dojnic
Kosourová, Gabriela
The aim of the bachelor thesis is the prevention and treatment of mastitis in dairy cows. The first part deals with the anatomy of the mammary gland. The second part, milk production will be discussed. In the next part, the division of mastitis will be discussed and described. Each mastitis has different symptoms, course of infection, duration of treatment and mainly pathogen resistance to antibiotic treatment. In the final part will be discussed diagnostics, treatment and prevention. In prevention, I will focus on the correct procedure for milking, stable environment and dry-off.

Faktory ovlivňující výskyt mastitid ve vybraném chovu a návrh jejich řešení
TLUSTÁ, Tereza
A mastitis is an inflammatory illness of a milk gland, currently the mastitis is one of the most common health problems in cattle breeding. In most cases the mastitis is caused by bacterial infections of an udder, it can be also caused by viruses, protozoa, yeast, algae and molds. There are huge variety of factors reducing defensive immune mechanisms of the udder and predispose a cow for the inflammation. An etiology of mastitis and mainly ways of prevention are very interesting not only for dairy cows breeders, but also for researchers, scientists and veterinarians. Main reason is economy of dairy cattle the inflammation of milk gland reduces actual milk production, it can influenced milk yield in next lactations and lenght of productive life of the dairy cow too. Usually culling rate and death rate grow. The mastitis has negative effect on reproduction and health status of the cow, especially on hooves' health; that also leads to shortening of cow's productive life and necessity of faster replacement of affected cows by heifers. An aim of this work is to found out risk factors which enlarges chance of the mastitis. Rate of mastitis is influenced by an age of a cow and a number of lactation, a number of days in lactation, an age of a cow at the 1st calving, an yield of the previous lactation, cases of mastitis at the 1st and next lactations and health problems on start of a lactation. A number of treated teats is influenced by an age of a cow at the 1st calving, an yield of the previous lactation and days of the dry-period. Negative effect of mastitis on the reproduction wasn't completely demonstrated; there were only found out that higher number of treating cases extends time between calvings.

Měření změn povrchové teploty vemene při procesu dojení metodou infračervené termografie
Goldová, Martina
This thesis was focused on measuring changes in surface temperature of the udder using infrared thermography. At the beginning, work dealt with the anatomy of the mammary gland, disease of the udder, milking machine and structure of milking ma-chine. The practical part was focused on infrared thermography and its use and an attempt was made, which examined the impact of the milking machine to the udder and teats temperature using an infrared camera. The experiment was made in the farm Petrkov on breed cows Jersey cattle, Czech fleckvieh cattle and Holstein cattle. Finally, of this work discusses the influence of the milking machine to the udder temperature.

Sledování morfologické stavby vemen u plemene zwartbles
MACHO, Michal
This thesis deals with the monitoring of morphological structures udder of breed zwartbles. Measurements were performed at 77 selected ewes Measured values for individual dimensions: Depth of udder reaches an average size of 17.74 cm. Width of udder reaches an average size of 14.77 cm and average length of the teat has a value of 3.11 cm. Based on measured values it shows, that breed zwartbles has potential for milk production as is the case in sheep improved Wallachian and Lacaune The position of the teats has an average value of 2.22 points. The teats are directed slightly to the side and are located at the lower edges of the udder. Clamping of the udder has an average value 2.08 points. The Clamping is broad and overall space between the rear legs is almost the entire filled Split udder has an average value of 2.53 points. The splitting is weak, but distinct and hanging ligament is perceptible. Monitoring diseases and disorders of the udder in the years 2013, 2014, 2015 and 2016. In year 2013, was the incidence of disorders on the value of 6.72%. In year 2014, this number had a value of 10.34%. In year 2015, equal to 5% and in year 2016 5.7%. This was the shortage of milk, the teat ducts impassibility and infections
