While inbreeding coefficients tell you how closely related the parents of an individual are, coancestry tells you how related the herd is — and that’s the real lever for managing long-term inbreeding. 

Example: A sire with a moderate inbreeding value, but no relation to your cows, may result in zero inbreeding in their progeny. However, using that sire extensively will make the next generation highly related, limiting your future mating options. 

MateSel uses parental coancestry to manage genetic relationships across the herd. It’s a more effective way to safeguard future genetic diversity and genetic gain.
