Causes of pre-weaning lamb losses under farm conditions were investigated among the Shugor and Dubasi ecotypes of the Sudan Desert sheep. On average, these losses accounted for 40.5% of the lamb crop, but for the separate ecotypes these figures were 44.3 and 36.7%, respectively, for the Shugor an...

A ten-week trail was conducted to assess the nutritive value of molasses urea blocks (MUBs) for feeding sheep in the Sudan. Sixteen adult wethers of the Sudan Desert sheep of 51.8± 0.1 kg average liveweight were used. After a three-week preliminary period, the animals were divided according to li...
