Abstracts
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 (P<0.001). The basic components of milk, somatic cell count (SCC=452.2 thousands) 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 (P<0.001). The content of fat (7.72 %; F), lactose (4.62 %; L) and protein (5.68 %; P) were significantly affected by the CM (P<0.001, P<0.001 and P<0.05 respectively). The significant phenotype and residual correlations we determined between L and SCS (r = -0.372 and -0.399 respectively; P<0.001). The ewes with the worst UHS had on the basis of phenotype and residual correlations significantly lower lactose content in the milk (r = -0.206 and -0.194 respectively; P<0.001 and P<0.01 respectively). Between SCC and UHS and between SCS and UHS we found only weak phenotype and residual correlations (P<0.05 and P>0.05 respectively).
