Inbreeding seems to be a useful tool to improve the
population by increasing the frequency of desirable genes, but the first result of
inbreeding is inbreeding depression. Inbreeding depression implies the
reduction of additive genetic variance and phenotypic values for efficiency
traits in inbred animals. The kinship degree is measured by the inbreeding
coefficient and expressed in percentage (%) from 0 to 100, that as the
percentage higher, the higher the kinship. Nevertheless, one thing is for sure,
practice in sheep breeding has shown that the use of inbreeding causes
undesirable consequences like reduction of body shape or abnormal
development, developmental delay, resistance to external influences and
diseases, poor fertility or infertility, metabolic disorders, negative
characteristics in fattening, albinism and the appearance of degenerative
traits, loss of instinct, psychophysical defects and so on. Inbreeding is an
inevitable companion of livestock p...roduction. No matter how hard we try to
avoid it, in practice, it is almost impossible. It could not completely eliminate,
but with proper breeding and selection management, it can be kept under
control.
