This article corrects Crop & Pasture Science 75, CP23172. doi:10.1071/CP23172

The authors advise of an error in Tables 2, 3 and Supplementary material tables of the published paper. The values in these tables should be in g/kg, but the authors instead used an incorrect conversion factor which is regretted.

On page 8 of the published paper, the last sentence at the end of fourth paragraph incorrectly reads as:

‘DMD did not significantly differ among forage associations, and all mixtures might be considered of good quality in terms of digestibility, with values >55%’.

The correct sentence should be:

‘DMD did not significantly differ among forage associations, and all mixtures might be considered of good quality in terms of digestibility, with values >550 g/kg DM’.

The correct Tables 2, 3 and Supplementary Tables S1 and S2 are provided below:
