In Tunisia, the marketing of lamb is in the majority of farmers after weaning at relatively low weight. Thus, it was deemed necessary to conduct a test of fattening lambs Tunisian landraces (Barbarine (BGQ), fine Tail from the west (QFO) Black Thibar (NT) and Sicilo-Sarde (SS) after weaning to evaluate their growth performance and determine the quality of carcasses and meat. To do so, four uniform lots of lambs (age and weight) were conducted simultaneously in two months and fed with oat hay ad libitum supplemented with 300g of concentrate/day/lamb. It was clear from this work that the lambs of the breed Black Thibar had better daily growth (87.5g vs. 64.2; 66.3, 72.6 respectively for the QFO, BGQ and SS), feed efficiency (5.94). The quality of meat (6.89% fat) and pieces of the first category (leg, the net and found the square (53.43%). To enjoy optimum production of red meat, it is strongly recommended that fattened lambs after weaning with diets tailored to the farming area where profitability is better and food is available.
