About Inbreeding Coefficients (COIs)
Inbreeding coefficients are a measure of the increased percentage in homozygous (same) gene pairs in an individual in comparison to the breed average. A goat that is inbred is "more likely to have identical gene pairs, so is more likely to express undesirable characteristics from recessive genes, leading to a decline in performance called inbreeding depression" (Shepard, "Practical Genetics for Dairy Goat Breeding," http://certification.goats.langston.edu/login/index.php, p. 293.).
Depending on the source, the recommended ceiling should be somewhere between 5% and 12.5% after all generations are considered.
Inbreeding is practiced industry-wide with Nigerian goats. It is not unusual to find animals with Coefficients of Inbreeding (COIs)* as high as 30%-60% when tracked using Kintraks. Caution should be exercised when using ADGA Genetics as it is missing pedigree data for the breed and thus reports inaccurately low COIs.
There are concerns among breeders and researchers that excessive use of inbreeding is resulting in health conditions such as carpal hyperextension and squamous cell carcinoma.
