Abstract | The chosen traits of production, composition and quality of milk (analysis of 255 milk samples) were evaluated in ewes on the 1st to 3rd lactation (n=64) during milking period (4 control measurements – CM) and in the machine milking conditions. Udder health status of the ewes (UHS, n=255) was evaluated by means of 5 point linear scale subjectively at the same time. The ewes of three pure breeds (Tsigai – T, Improved Valachian – IV and Lacaune – LC) and two crossbreds (TxLC and IVxLC) were involved in the experiment. The machine milked milk (milk production) at CM (0,462 kg), the proportion of machine stripped milk (25,19 %) and also UHS (1,65) were significantly affected by the genotype group.The basic components of milk, somatic cell count (SCC=452,2 housands) and somatic cell score (SCS=2,32) were not significantly affected by the genotype group. UHS of the ewes was effected by the genotype group and lactation order. The content of fat (7,72 %, F), lactose (4,62 %, L) and protein (5,68 %, P) were significantly affected by the CM. |
