Abstract
Aim: The objective of this study was to evaluate the effects of introducing Sugar Beet bulb as a cheap substitute for grains in rations formulated for sheep fattening.
Materials and Methods: This trial was conducted at the Experimental unit of Rural Development and extension center, Faculty of animal production, University of Gezira. Twenty four Sudanese desert lambs (Ashgur ecotype) were purchased from local markets to assess the effects of replacing grain with Sugar Beet (Beta vulgaris saccharifera) Bulb on feed lot performance, carcass traits under tropical conditions of Sudan. Sugar Beet bulb was incorporated in three rations with a control ration (A: control, B, C, D) at percentages of 0, 11, 22, and 33.
Results: The results showed that total weight gain and daily feed intake in group D were significantly different at (P<0.05) where values of 5.59 +/- 1.73 and 0.94 +/- 0.13 kg were recorded. Total weight gain, daily dry matter intake, daily energy intake and feed conversion ratio were in the range of 10.67-5.59, 1.03-0.83, 0.33-0.27and 11.77-7.70 kg respectively. Treatments showed no significant differences at (P<0.05) for slaughter weight, empty body weight, dressing % on slaughter weight basis and dressing % on empty weight basis, the obtained results for these traits were 27.78-25.37, 24.76-22.22, 45.80-43.45% and 51.41-49.65%. Carcass cuts (Leg, Loin, Rack, Plate and Neck & shoulder) weight and percentages showed no significant differences among treatments.
Conclusion: It is concluded that replacing expensive grains with Beta vulgaris bulb can be practiced in sheep fattening project up to 22% with excellent results.
