ABSTRACT Culled Nubian males are important for meat production in the Sudan, but nutrition is a main constraint. Sugar beet is recently introduced for sugar production in the Gezira State and is a valuable feed. Seewa is sorghum cobs residue with low nutritive value and could be supplemented to improve the nutritive value and animals performance. There is no information on using upgraded Seewa and dried sugar beet root (DSBR) based concentrates level on Nubian kids performance and carcass characteristics. Consequently, 12 Nubian male kids at 6 month old were used to furnish this vital information. They were weighed and allocated at random to three experimental feeds and housed in individual pens with feed and water trough. They were fed upgraded Seewa (UGS) ad lib. at 8 am and 4 pm and refusals were collected, weighed and stored for laboratory analysis. The animals were fed DSBR based concentrates at 0 (control), 250g and 500g in two meals before UGS. Samples of feeds and refusals were stored for laboratory analysis. The animals were allowed a two weeks preliminary period and weighed weekly for 8 weeks. Data were statistically analyzed using ANOVA. Seewa had low CP and high CF and upgrading increased CP. Mean upgraded Seewa DMI varied among concentrates levels, but not significant (P>0.05) and were highest in animals fed 250g concentrates and least in animals fed 500g concentrates. Mean total dry matter intake (TDMI) increased significantly (P<0.05) with concentrates level. Mean water intake, body weight (BW), weekly weight gain and feed conversion ratio (FCR) increased with concentrates level, but differences were not significant (P<0.05). It was recommended to use DSBR based concentrates and upgraded Seewa in fattening Nubian male kids.
