Abstract

The aim of this study was to determine the effects of incorporating three local oasis by-products [cull dates (CDs), date pedicels (DPs) treated with urea, and juice from rumen content] into the food ration of Ouled Djellal lambs on fattening performance and carcass characteristics. The experiment was carried out over 105 days, with an adaptation period of 15 days, on four groups each consisting of 10 male Ouled Djellal lambs aged 7-8 months with an average live body weight of 32±1.5 kg, randomly distributed, and raised in tie stalls. The basic rations were formulated at a rate of 0% (control), 50%, 80%, and 100% substitution of barley straw by DPs treated with urea. The additional rations intended for the experimental groups consisted of 100% substitution of corn by CDs. Before distributed, they were sprayed with rumen content extract (RCE) at a rate of 250 ml/kg. The 100% group displayed a highly significant difference compared to the other groups, with a live body weight of 43 kg (p
