Table 1 A summary of challenges found in cattle farming in tropical regions and potential contributions of genome editing
From: Genome-editing opportunities to enhance cattle productivity in the tropics
Challenges | Genome modifications | Expected contributions |
|---|---|---|
High temperature and humidity | Introduction of SNPs in the prolactin receptor gene Deletions in the Pre-melanossomal protein 17 gene Introduction of heat tolerance SNPs of Bos taurus indicus in B. taurus taurus cattle | Decrease the heat stress in Bos taurus taurus cattle |
Poor milk yield performance | Introduction of SNPs associated with milk yield | Increase the milk production in B. taurus indicus cattle |
High ectoparasites infestations | Disruption of transformer (tra) gene in C. hominovorax Introduction of tick resistance SNPs of B. taurus indicus in B. taurus taurus cattle | Control of screwworm infestations Increase the tolerance to tick infestations in B. taurus taurus cattle |
Emission of greenhouse gas | Disruption of methanogenic archaea genes associated with methane production in the rumem | Decrease the cattle methane emission |
