الملخص
Our work, concerning the fattening of lambs males, of white race includes 2 steps, the first onein a farm of state studies the breeding’s methods and the zootechnic performances of 20 lambsfattened during 50 days by calculating the quantities of food distributed and the evolution ofweight. The second step achieved in the slaughterhouse, is based on the survey of features of 100carcasses destined for the consummation. The measured parameters are the weight, a set of linearmeasurements of the body as well as the thickness of the dorsal greasiness; tests of classificationare driven by application of statistical models GLM, ACP and Tree-Based Model.The retained conclusions demonstrate an inadequate breeding method with a deficient feeddistributed without any distinction of age or category, the favourable evolution of weight isassigned to the continuous consummation of maternal milk.The survey of features of carcasses confirms the bad management of fattening in spite of thegood conformation of animals.The tests of classification, by using classic regrouping of carcasses in 3 categories of weight,could have two other methods of discrimination: one according to the thickness of the dorsalgreasiness and the other according to the length of the carcass and widths of the carcass and thethorax. They represent an example of the multiple orderings that can be adapted to establish aspecific quotation grid to our slaughterhouses
