The genetic and phenotypic parameters for pre-weaning weights of Sudan Desert sheep were investigated to provide information as a basis for improvement schemes for the Sudan Desert sheep. Records of 2298 Desert lambs were used to study breed type and environmental factors influencing pre-weaning weights and for parental half-sib estimation of genetic parameters. Shugor lambs were heavier at all ages (P0.85) between birth weight and 60-day weight, birth weight and weaning weight, birth weight and pre-weaning growth rate, 60-day weight and weaning weight, 60-day weight and pre-weaning growth rate and between weaning weight and pre-weaning growth rate.
