Genomic evaluation for calf wellness traits in Holstein cattle
Here is the summary statement by the authors:
"The results [of this study] indicate direct evaluation of calf wellness traits under a genomic threshold model is feasible and offers predictions with average reliabilities comparable to other lowly heritable traits."
Well, it sounds like although heritability for calf wellness is on the low side it is measurable.
Let's keep this idea in the back of our minds as a possible management tool in the coming decade.
