The paper examines the qualitative features of lamb pelts of Botosani Karakul breed from a private farm in which the selection criteria were adjusted according to the market requirements in the fur clothing field. The experimental observations lasted 10 years (2005-2014) examining these qualitative features in their evolution, on the one hand, as regards the physical and morphological characteristics of curling of lamb pelts, and on the other hand, in terms of hair fibre colour. The following trends of selection were profiled concerning the fixing of qualitative peculiarities of lamb pelts in this farm: I) modelling of curl shape from those of heterogeneous type to curls of cylindrical tube, cylindrical tube+grain and grain type; II) dimensioning of curls from big size to a middle-small size; III) improving the quality of hair fibres becoming more silky or normal by transforming the rough and soft hair fibres; IV) a significant increase in the incidence of intense lustre of hair fibres but also a considerable frequency of fibres with good+very good lustre; V) decreasing the number of individuals of black variety, maintaining in a constant and high proportion of lambs of greyish variety and an increase in the number of brown lambs and especially of the grey ones; VI) a better framing of lambs in upper zootechnical classes (Record and Elite). Generally, the differences among experimental phases (years) concerning the qualitative features of lamb pelts present significant statistical assurance.
