New genome editing methods promise to revitalize transgenic livestock research. This advancement could deepen our understanding of animal biology and enhance disease resistance in farm animals.

Area of Science:

  • Animal Biotechnology
  • Genomics
  • Livestock Science

Background:

  • Current transgenic livestock generation techniques are inefficient and costly.
  • Complex agricultural traits controlled by multiple genes limit the application of transgenic technology.
  • There is a need for improved methods to overcome existing limitations in livestock genetic modification.

Purpose of the Study:

  • To highlight the limitations of current transgenic livestock technology.
  • To emphasize the potential of novel genome modification methods.
  • To project the future impact of advanced genetic engineering on livestock research.

Main Methods:

  • Review of existing transgenic livestock generation techniques.
  • Discussion of the genetic basis of agriculturally relevant traits.
