In the article by Blunk et al. (Reference Blunk, Mayer, Hamann and Reinsch2017), presented in Animal, inadvertent mistakes were made. This concerns the formula used to calculate the reliabilities of estimated parent-of-origin effects (POE), where the factor of 1/2 in the denominator has been omitted. The correct formula should read:

$r^{2} \,{\equals}\,1\,{\minus}\,{{{\rm PEV}} \over {{{\bf{1}} \mathord{\left/ {\vphantom {{\bf{1}} {\bf{2}} }} \right. \kern-\nulldelimiterspace} {\bf{2}} }\,\sigma \,_{i}^{2} \left( {1{\plus}{\bf{F}} _{i} } \right)}}$,

where F i is the inbreeding coefficient of ancestor i.

Therefrom, reliabilities had to be calculated, which led to a number of changes (highlighted in bold letters) in the different chapters of the manuscript, as outlined below. All other results and conclusions remain, however, unchanged.

In the Abstract it is stated that the reliabilities of POE ranged between 0.4 and 0.9. However, the recalculation of reliabilities according to the formula above led to reliabilities ranging between zero and 0.9.

With regard to the chapter ‘Reliability of parent-of-origin effects and genetic trends’, the recalculated reliabilities of the POE are summarised in the following table:

Range and average of the reliabilities recalculated for the parent-of-origin effects predicted for the net BW gain, fat score and conformation class

1 Treated as ordered categorical traits using a generalized linear mixed model.

Moreover, in this chapter differences in the average reliabilities of sires were shown depending on the number of their progeny. The reliabilities were recalculated according to the formula above so that sires with differences in the average reliability for the estimated POE on the net BW gain had the following average numbers of sons, daughters and maternal grandsons:

Further, the reliabilities in Figure 1 needed to be adjusted:

Parent-of-origin effects were estimated using a linear mixed model for the net BW gain (g/days) (a, b), fat score (c, d) and conformation class (g, h). Parent-of-origin effects were estimated using a generalised linear mixed model for the fat score (e, f) and conformation class (i, j).

The authors apologise for the error.
