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
