Abstract
The average values of individual udder dimensions were determined in three populations sheep: domestic population i.e. ovcepolian sheep, awassi sheep and F1 crossbreeds between awassi and domestic population. The influence of several factors on the udder dimensions is shown in parallel in the three populations. Regarding the statistical analysis, besides the basic statistics, all the data were analyzed by multi trait fixed model. The separate trait influence
was studied by the F-test, and the differences between LS – estimates of each effect were determined by the T-test. The analyses were made by the set of programs SPSS. The genotype had a highly significant influence (P<0,001) on the udder measurements in the three tested populations, while the lactation in order (age) and lactation month had an influence on some of the udder measures.
The determined increase in certain dimensions i.e. udder measurements, in the F1 crossbreeds point to a positive effect of crossbreeding awassi and domestic population sheep, which has to result on higher milk production.
