Computing Inbreeding Coefficients and Effects of Inbreeding, Heterosis and Recombination Loss on Evaluations for Lifespan and Somatic Cell Count in the UK

چکیده
A recent study on the Holstein/Friesian (HOL) breed has indicated that the rapid rise in percentage Holstein genes in the United Kingdom (UK) has been accompanied by an increasing rate of inbreeding (Kearney et al., 2004). They reported an average inbreeding rate of 0.17% per year since 1992. Some of the consequences of inbreeding, for instance, inbreeding depression, are expected to be more pronounced in fitness traits such as somatic cell count (SCC) and lifespan (LS).

In this study, pedigree data of 7170 lambs produced from 177 rams and 2182 ewes collected during 1989 to 2009 in the Shirvan Kordi sheep breeding station, were used for calculating inbreeding coefficients. The impact of inbreeding on the studied traits was investigated by including inbreeding coefficients for each animal as a covariate in the animal model. Average inbreeding coefficient of the ...

A pedigree file consisting of 5860 individuals, 167 sires and 1582 dams collected at Makooei sheep breeding station (MSBS) during a period of 24 years (1990 to 2013) was used to calculate the inbreeding coefficients to reveal any probable effects of inbreeding (F) on the studied traits. The studied traits were classified to the five main groups including body weight, Kleiber ratio, body measure...
