Summary

A total of 24 desert lambs were divided into four groups fed either of two levels of poultry litter (PL), 30% or 50%, so that with each level, dura grains were supplied either in whole or crushed forms. The daily dry matter intake (DMI) of the different rations was not affected with the level of (PL) in the ration, but was affected by processing (crushing) of the grains. Rations fed with the crushed dura was significantly (P < 0.05) consumed in larger amounts irrespective of the level of poultry litter in the ration.

The liveweight gains (LWG) of the lambs in the 4 treatments (30% PL with whole grains, 50% PL with whole grains, 30% PL with cr1ushed grains and 50% PL with crushed grains) were 13.46, 13.41, 15.75 and 17 kg respectively for the total period. This parameter was not affected with the level of (PL) in the ration, but was significantly improved by processing (P < 0.05). The feed conversion ratio (FCR) and

the dry matter digestibility (DMD) of the different treatments were found to be apparently improved for the lambs fed 50% (PL) and crushed grains.

No health problems were encountered with increasing (PL) level in the ration. It is concluded that (PL) can be included to the level of 50% in rations of fattening lambs, and the best performance was obtained with crushed grains.
