Inbreeding is a population genetic parameter that is crucially important in cattle breeding. It happens when related cattle mate and it can’t be stopped, especially in small groups. Calves whose parents are linked will receive homozygous genotypes that came from ancestors they both had.

Inbreeding among cattle can exacerbate various issues, including disease susceptibility, diminished performance, decreased overall health, and other undesirable traits passed down through generations. This detrimental outcome is often referred to as “inbreeding depression.” 

Responsible cattle farming practices are essential in mitigating the adverse effects associated with inbreeding.
