摘要：

The objectives of this study were to analyse the influence of fixed effects on milk traits of East Friesian and Black-Brown milk sheep. The analysis was based on 9729 test day records of 1108 milk sheep with 1746 lactation records. The milk records were sampled from 1992 until 2000. Herds were located in Lower Saxony, Westphalia and Bavaria. The analysis of variance indicated that the lactation stage had a significant influence on all analysed milk production traits. For the East Friesian milk sheep the year of lambing was also significant for all milk production traits, The lactation number significantly affected in both analyses the milk, fat and protein yield, the fat content and the SCS. A significant influence on the milk yield could be shown for the region, the number of lambs born and the season of lambing. The fat yield and the protein content were significantly influenced by the breed.
