This study was conducted at North Kordofan State, Sudan, the study aimed to investigate the effects of parity order and supplementary feeding at mating, late pregnancy and pre-lambing period on ewe productive and reproductive perfor-mance for Desert sheep during the dry season. Eighty (80) ewes were selected from the flock of Desert sheep for this study. Ewes were weighed and randomly divided into four groups A, B, C and D, each group with 20 ewes, ewes were as-signed to supplementary feeding treatments as group A was supplemented with diet one, group B was supplement with diet two, group C was supplement with diet three and the last group D as a control. Supplementary groups A, B and C were offered with supplementary feeding for Four weeks during pre mating (flushing), Four weeks post mating, and two months pre lambing and three months post lambing. Supplementation was offered at evening with 350 grams/ewe/day. Body weight of ewes at pre- and post- mating, pre- and post- lambing till weaning was recorded. The data revealed significant (P > 0.05) effect of steaming up and supplementary feeding on body weight at mating and before lambing. Body weight improved significantly (P > 0.05) for supplemented groups compared with control one. Ewes in group A showed higher (P > 0.05) weight compared with other. Supplementation to ewes has positive effect (P > 0.05) on body weight at weaning. Parity showed higher significant (P > 0.05) effect on ewe's body weight, where weight was improved at mating and before lambing with increase of parity order. Also parity order has significant (P > 0.05) effect on body weight change post lambing and weaning time. supplementary feeding has significant (p < 0.05) effect to reproductive traits and prolificacy where conception rate, lambing rate increased in supplemented groups A, B and C as compared with group D, abortion rate was decreased. Conception and lambing rate were increased and abortion and mortality rate were decline d with advance of parity. Litter size was increased significantly (p < 0.05) with supplementation and parity. In conclusion Parity order and supplementation (flushing and steaming-up) with to Sudanese Desert ewes during breeding period had positive effect and improved the reproductive performance of the ewes.
