The result of an intensive 15 months study of 10 flocks of indigenous sheep is recorded. Lambing rates approach 1.5 lambs per ewe per year, but a death rate of 23 percent and on off take of 27 per cent, means that flock numbers are probably slightly declining. Twins account for 14 per cent of all...

The growth of 30 docked and 30 intact male Sudan Desert lambs was studied to weaning. The mean birth weight, rate of gain to weaning and weaning weight of the docked group were found to be 3.9 kg, 119g/d and 18.5 kg respectively; those for the intact group were 4.1 kg, 116 g/d and 18.0 kg in the ...

The study reports some of the reproductive traits, namely pregnancy length, ewe fertility and reproductive rate, pre-weaning survival and mortality rates of Sudan indigenous sheep under irrigated Gezira conditions.
In continuation with the previous studies on the blood composition of cattle and sheep in Khartoum province and Western Sudan, the total serum minerals, sodium, potassium and calcium have been determined. The figures are given in tables 1-3. It is evident that the mean albumin content was lower b...

Reports the comparative performance of indigenous Balami and imported Desert Sudanese sheep. The reproductive and growth performances of Balami and Sudanese Desert sheep were studied using 466 lambing record from 147 Balami and 126 Desert Sudanese ewes during 2-year period. The Balami was signifi...

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...
Plain (OAT), 1.4% urea-enriched (EOAT) and 3% themal-ammoniated (NH3OAT) oat grain were fed to South African Mutton Merino ewes as supplementary feed during late pregnancy and lactation, while grazing wheat stubble at 2 ewes/ha during 1986 and 1987. Blood glucose, urea, calcium, magnesium and zin...
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...
