The identification of breed-specific SNPs allows for targeted conservation efforts, ensuring the preservation of genetic diversity within and among buffalo populations. It is recommended that conservation programs incorporate SNP-based genetic monitoring to track genetic variation and manage breeding programs effectively. For instance, the conservation of the Nili breed in Pakistan, which has maintained its distinct status despite close evolutionary ties with the Nili-Ravi breed, underscores the importance of SNP markers in conservation planning (Anas et al., 2023). Furthermore, the development of SNP chips, like the 90K SNP genotyping assay, provides a robust tool for genetic diversity studies and can guide genome-assisted selection programs to enhance productivity and disease resistance in water buffalo (Iamartino et al., 2017). These efforts are crucial for maintaining the genetic health and sustainability of water buffalo populations globally. In summary, SNP markers play a pivotal role in the conservation and breeding of water buffalo by enabling precise genetic monitoring, identifying inbreeding trends, and informing conservation strategies to preserve genetic diversity (Rusdin et al., 2020; Kenchaiwong et al., 2023). 6 Applications of Molecular Markers in Breeding Programs 6.1 Marker-assisted selection (MAS) for desirable traits Marker-assisted selection (MAS) is a powerful tool in breeding programs that utilizes molecular markers to select for desirable traits in water buffalo. Single Nucleotide Polymorphisms (SNPs) are among the most widely used molecular markers in animal breeding, allowing for the identification and selection of traits such as milk volume, age at first calving, and feed conversion efficiency (Mishra et al., 2020; Mishra et al., 2021). The use of SNPs enables breeders to enhance productivity by selecting animals with favorable genetic profiles, thereby accelerating genetic improvement (Du et al., 2019; Ramlachan, 2023). Additionally, microsatellite markers have been employed to assess genetic diversity and support MAS by identifying genetic variations linked to economically important traits (Uffo et al., 2017; Singh et al., 2018). 6.2 Genetic improvement strategies using molecular tools Genetic improvement strategies in water buffalo have been significantly advanced through the use of molecular tools. Whole-genome sequencing and genome-wide association studies (GWAS) have been instrumental in uncovering candidate genes associated with productivity traits such as milk production and disease resistance (Du et al., 2019). These tools provide comprehensive genomic data that facilitate the understanding of complex traits and enable the development of targeted breeding strategies (Iamartino et al., 2017). The integration of these molecular tools into breeding programs allows for the precise selection of animals with superior genetic potential, ultimately leading to enhanced performance and adaptation (Marrero et al., 2016; Rehman et al., 2021). 6.3 Integration of genomic selection into breeding programs The integration of genomic selection into breeding programs represents a transformative approach to improving water buffalo populations. Genomic selection leverages high-density SNP panels, such as the 90K SNP chip developed for river buffalo, to predict the genetic merit of individuals with high accuracy. This approach enables the selection of animals based on their genomic estimated breeding values (GEBVs), which are derived from genome-wide data rather than traditional phenotypic assessments (Rehman et al., 2021). By incorporating genomic selection, breeders can achieve faster genetic gains and improve traits such as milk yield, disease resistance, and overall productivity (Mishra et al., 2021). The use of genomic selection is particularly beneficial in managing genetic diversity and ensuring the sustainability of breeding programs (Marrero et al., 2016; Ünal et al., 2021). In summary, the application of molecular markers in water buffalo breeding programs offers significant potential for enhancing genetic improvement. Marker-assisted selection, genetic improvement strategies using molecular tools, and the integration of genomic selection are key components that contribute to the advancement of breeding programs, ultimately leading to improved productivity and sustainability in water buffalo populations.
