The purpose of the research was to carry out a real analysis of the degree of improvement for the traits that influence the quality of skins obtained from Karakul of Botosani lambs. The biological material was represented by lambs of both sexes obtained from adult sheep belonging to the respective breed. In order to evaluate the improvement of the modeling degree, assessments were made on several generations of lambs, starting with those from 2007 when the current Improvement Program is applied, those from 2015, 2020 and respectively from 2022. The working methods used are accepted by the experimental technique and the evaluation of the type of model was made based on the technical norms and in which it is specified that 50 points are awarded for very good modeling; for good modeling, only 25 are assigned, and for situations in which the modeling is satisfactory, only 10 points are given. Following the statistical processing of the data, it is found that the improvement process is more advanced in black variety lambs because an average score of 32.38 was obtained and from the total number of lambs evaluated in 2022, the proportion of those that were also associated with a valuable modeling was 66.8%.
