So, in terms of health, a COI less than 5% is definitely best. Above that, there are detrimental effects and risks, and the breeder needs to weigh these against whatever benefit is expected to gained. Inbreeding levels of 5-10% will have modest detrimental effects on the offspring.

WebAug 28, 2024 · The inbreeding coefficient measures the percent increase in homozygous gene pairs in an individual relative to the average of the breed. If an individual has an inbreeding coefficient of .25, it means that it is expected to have 25% more homozygous gene pairs than a non-inbred individual from the same population.
