Evaluation of mastitis in selected dairy fading
LIŠKA, Zdeněk
Bachelor thesis deals with the evaluation of diseases of dairy cattle called mastitis. This is an inflammatory disease of the mammary gland, which is among the most common and economically the most serious disease of cattle. This disease negatively affects a whole range of factors. One of the easily observable indicators of health status of the mammary gland is the number of somatic cells in milk.

Mastitis monitoring and factors influencing mammary gland health
DVOŘÁKOVÁ, Kamila
The thesis explores an issue of mastitis in dairy cows, and factors that influence the health of a mammary gland. In span of 2012-2013, 629 quarter samples of milk were collected, the somatic cells count (SCC) was determined and the results related to the condition of teats base, and also to an order and phase of lactation. The results were compared to the pool samples collected in 2008-2013 (SCC, TBC) and the number and development of clinical mastitis was followed (2012-2013). The condition of teats base was estimated as an important factor contributing to the health of a mammary gland. The lowest SCC was identified in the first phase of lactation, and, contrary to that, the highest SCC was identified in the third phase of lactation (active involution). The order of lactation proved to be an important factor influencing SCC in milk. Dairy cows staying in pasture were shown to have less SCC in milk; it can therefore be concluded that grazing has a positive impact on SCC in milk. In the examined period, very low number of clinical mastitis was determined

Current methods of prevention and possibilities of treatment of bovine mastitis
DVOŘÁKOVÁ, Kamila
My bachelor work called Current methods of prevention and possibilities of treatment of bovine mastitis has been created with a view to the fact that mastitis is one of the most economic significant disease of cattle . The prevention of mastitis includes individual measures important for maintaining the health of dairy cows. The basic principle of prevention is to avoid weakening the natural immunity of dairy cows and especially of the mammary gland as such. To maintain healthy mammary glands the welfare of the cows is important. Dairy cows should be properly housed and fed a high quality, harmless food. An important measure is the correct milking procedure. Pasture has a very favourable effect on the health and welfare of dairy cows. An important aspect in the prevention of mastitis is drying off which is often carried out at a flat rate and globally. The use of non-antibiotic cements is a new trend of drying off, only usable in dairy cows with healthy mammary gland. Research in the immunoprophylaxis of mastitis is still ongoing, because the etiology of mastitis is not yet entirely clear. Conventional treatment of mastitis is based on the use of antibiotics during lactation or during the dry period. According to the seriousness of the disease is selected a local or total application or a combination of both. Supplementary treatment is the application of enzymatic preparations which reduce the required dose of antibiotics and accelerate healing. The unconventional treatment of mastitis that is more common on organic farms, is represented by homeopathy and phytotherapy, which are used mostly in mild inflammation of the mammary gland. If therapy should be an effective, early start of treatment is very important.
