الملخص EN

This experiment was carried out at the experimental farm, Faculty of Agriculture at Moshtohor, Banha University, Egypt, on 20 Ossimi male lambs to investigate the effect of management systems (10 lambs in intensive and 10 lambs in semi-intensive management system) on lambs live performance, feed conversion and economical feed efficiency in addition to lambs carcass traits.

The results showed that management systems showed a significant effect on lamb’s live performance and carcass traits.

Lambs growth performance of intensive management system group was better than semi-intensive management system in final live body weight (43.50 vs.38.80 kg), average daily gain (0.238 vs.

0.192 kg/day) and lambs economical feed efficiency (1.43 vs.

1.24), respectively.

Hot carcass weights, dressing percent, prime and second cuts of lambs in intensive management system were significantly higher than lambs subjected semi-intensive management system.
