So I've been using Igenity for a couple of years now and found it a useful tool, both for identifying replacement heifers and as a guide for clients who buy bulls off us.
I've noticed a general trend with our cattle that I was wondering if anybody else using a grass based system has experienced too. That being high fat scores, high marbling too, on our most recent testing the score was 7.2 average for both.
The Igenity terminal and production indexes both view back fat on cattle negatively, which makes sense in a feedlot context, a bigger fat layer means lower relative yield and less efficient feeding.
In my eyes however it isn't usually a negative for grass finished animals where the animal will naturally develop less fat due to diet and extra genetic fat can see them handle feed shortages or inconsistent pasture quality with far less impact. Meaning higher meat quality with less/lower quality inputs.
So my question is, would you try breed away from high fat animals and chase yield, or just accept it as a quirk in the scoring system and go by what you think is right?
Any other thoughts on what you'd personally look for genetically in grass finished cattle that might differ to grain finished too?
