FM El-Hag, M-KA Ahmed, LMA Musa., Genetic weight phenotypes of Kabashi desert sheep in Sudan, Onl J Vet Res., 24(8): 503-509, 2020. We describe genetic and phenotypic weight traits of 572 Sudan desert lambs (Kabashi subtype), sired by 21 rams over 9 years. Season of birth, gender and lamb type at birth accounted for 17.4-37.7% of phenotypic variance for body weight and gain. We assessed body weight at birth and 30, 60, 90 and 150 days. Highest h2s was for weight at birth (0.270.113) and lowest at 120 days (0.070.088). Highest h2s for weight traits was 30 days (0.230.151) and lowest at 90 days (0.130.097). Body weight at birth genetically correlated with that at 30 days (0.62), whilst at 30 correlated with 120 days (0.76). Phenotypic correlations among body weight traits tended to decrease with age, whereas the genetic correlations among weight gain traits were all positive and tended to increase with age. The pattern of genetic correlations among body weight traits showed possibility for indirect selection for 120 days by selecting values at 30 days. However, more data on lamb weights and growth need to be collected and analyzed. Furthermore, there is a high need for delineating phylogenetic relationships among the different subtypes of Sudan Desert sheep in the country.
