Inbreeding in the united states.
When inbreeding and kinship levels started at zero inbreeding rates over a six‐year period (the period used in the real population) varied between flocks from 0.26% to 0.31% in the calculations, and from 0.11% to 0.15% in the simulations between year 2 and 8 (Table (Table2). 2). Variation between flocks almost disappeared when the inbreeding ...

Inbreeding*. Male. Pedigree. United States. The estimate of inbreeding for registered Holstein females born during 1990 was 5.1 +/- 0.4% for a random sample of 600 two-line pedigrees. Previously published estimates were 4.7% for 1970, 3.8% for 1976, and 4.3% for 1982 from similar samples of pedigrees. These estimates were calculated using a b ….For the captive population, the average pedigree-based inbreeding coefficient was F Ped_5gen =0.013. However, pedigree founders were already related by an average F Ped_18gen of 0.030 ( Forstmeier et al., 2004 ). Thus, the birds from our captive population had an F Ped_23gen of approximately 0.030+0.013=0.043.

Inbreeding coefficients are calculated routinely for all animals included in national genetic evaluations for yield traits. The base population for inbreeding is defined as animals born during 1960.
