Mikrobiální jakost syrového kravského mléka ve vybraných chovech. / Microbial quality of raw cow's milk in selected breeds.

Graduation theses were inquired into question of presence of total bacteria count (TBC) in four selected cattle-raising. The breeds differ from each other with technology of lairege and milking, predipping, grazing and herd size. The first was lairage in stanction housing and in-stall milking pipeline system and embodied average values TBC from 10 {$\bullet$} 103 {$\bullet$} ml-1 till 179 {$\bullet$} 103 {$\bullet$} ml-1. The second breed was lairaged in loose grate without littered housing and got milking parlour and embodied average values TBC from 5,5 {$\bullet$} 103 {$\bullet$} ml-1 till 68,75 {$\bullet$} 103 {$\bullet$} ml-1.The third and the fourth breeds were lairaged in loose cubicle littered housing and got milking parlour and embodied average values TBC from 5 {$\bullet$} 103 {$\bullet$} ml-1 till 34,33 {$\bullet$} 103 {$\bullet$} ml-1. There was not statically conclusive difference in analysis of total bacteria count on level - significance P < 0,05 between lairage in stanction littered housing and in-stall milking pipeline system and lairage in loose cubicle littered housing and milking parlour and lairage in loose cubicle littered housing and milking parlour, when the Students test was used. The stud with lairage in loose grate without littered housing and milking parlour had the top microbial contaminaton of milk. It had serious defections of hygiene lairage and milking. It succeeded to significant differences in value TBC in bulk milk sample on level - significance P < 0,05.
