Sažetak
Milking characteristics and udder evacuation in 3 different quarter specific milking routines were evaluated. The findings are based on single quarter milk flow profiles of 10 cows. Each treatment was applied in blocks of 4 subsequent milkings. After the fourth milking of each treatment 10 I.U. oxytocin were i.v. injected to obtain the residual milk. The intramammary pressure was recorded during pre-milking stimulation and after the teat cup removal to study the course of the milk ejection. Quarter specific milking routines avoided an overmilking of single teats, and partially decreased the total machine on-time. In comparison to non-stripping routines, the stripping routines had no benefit on udder evacuation or machine on-time. The milk ejection in single quarters was completely terminated when the milk flow ceased and the teat cups were removed. The degree of udder evacuation was therefore not influenced by the tested quarter specific routines.
