Thirty five male and female Sudan Desert and Taggar goat kids has been investigated to study the effect of sex of kids on birth weight, growth rate and weaning weight of Desert and Taggar goats under traditional management system depended on natural grazing in South Kordofan state at Al Debabat locality. The result revealed that Desert male kids had significantly (p< 0.0l) higher birth weight (2.25±0.08kg) than Taggar male kids (2.00±0.06 kg) and Taggar female kids had a significantly (p< 0.0l) lower birth weight (1.91±0.04) than Desert female kids (2.08±0.10 kg).The growth rate for three month of age was significantly (p < 0.0l) higher for desert male and female kids compared with male and female of Taggar kids. Large body weight gain per day (p< 0.0l) scored by Desert kid. Sex of kids had higher significantly (p< 0.0l) effect on body weight at weaning, where Desert male kids had significantly (p< 0.0l) higher weaning weight (11.88±0.45kg) than Taggar male kids (8.70±0.20 kg) and Desert female kids had a significantly (p< 0.0l) higher weaning weight (10.07±0.20) than Taggar female kids (8.12±0.28 kg). Also there was significantly (p< 0.0l) higher between male and female of Desert kids.
