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.
