“…The GDF-9 gene is responsible for the external regulation factor in the production and secretion of oocytes and has an important role in the growth and differentiation of both follicles (folliculogenesis) at an early stage (as well as granulose cells) and (theca cells) in sheep ovaries [22,23]. The studies of [24][25][26][27][28][29][30], showed that mutations in the GDF-9 gene have direct effects on litter size by increasing the rate of ovulation.…”

This study was conducted at the Ruminant’s Research Station, Office of Agricultural Research, Ministry of Agriculture, Iraq, For the period from 20/12/2021 to 1/9/2022, to detect GDF-9 gene polymorphism in Local and Shami goat, The genetic material was separated and nucleotide sequencing technology was used to detect mutations in the studied segment of (GDF9) gene, to determine the relationship of the resulting genotypes to the characteristics of growth, milk production and Litter size. The results of the study showed the presence of the mutation (C2006A) in the GDF-9 gene in both local and Shami goats. And it appeared with two genotypes were identified, wild (CC) and hybrid (CA), as the percentage of individuals carrying the wild genotype was (90.91, 92.31)% compared to the hybrid individuals (9.09, 7.69)% in the local and Shami samples, respectively, and the allelic frequency of the wild allele C was superior in Both strains (95, 96% balanced by the mutant allele A (4,5%). The results showed a significant effect of the polymorphism of the mutation (C2006A) in the characteristics of the weaning weight and the current weight in the local sample and in favor of the individuals carrying the hybrid genotype CA (19.25, 38.19) kg, while in the Shami goat sample, a significant effect was found for the genetic variation caused by the mutation (C2006A) in weight at birth for the benefit of individuals carrying the hybrid genotype (2.93) kg, and the results showed a significant effect of the multiplicity of genetic manifestations of the mutation (C2006A) in producing Total milk and Litter size in local and Shami goats in favor of individuals carrying the hybrid genotype CA (454.23, 497.39) kg and (1.57, 1.89) Kids/litter, compared to individuals carrying the wild genotype CC (450.10, 441.27) kg (1.21, 1.11) Kids/litter in the local and Shami samples, respectively.

Sudan is home to a large population of indigenous livestock breeds and represents a major source of meat suppliers to the Arab world. Indigenous sheep are critical for the subsistence, economy, and social well-being of large people in Sudan. They have acquired unique features regarding adaptation to the local environmental conditions. Domestic and wild sheep farming in Sudan is covered in this chapter, with a focus on its production systems, production challenges, and production potential. The results indicated that the majority of livestock species including sheep are produced in Kordofan and Darfur States. Two different production systems are used for producing sheep: The conventional low-input production system in remote areas and the modern or semi-intensive production system close to the major cities. The physical characteristics, tribal ownership, or geographic and ecological distribution are used to classify Sudanese sheep. However, Desert sheep types are the most common native sheep populations in Sudan, and they are a significant source of mutton production for both domestic and export markets. Conventional sheep farming systems typically encounter a number of production issues, such as inadequate feed, the prevalence of diseases, and a lack of transportation networks connecting the production and consuming regions. Additionally, structured breeding programs are not available for rural smallholder sheep farmers. These difficulties are probably going to reduce the sustainable production of sheep, their economic value to the country, and their ability to be used to their maximum potential.
