We entered some steers in a hoof and hook competition which we did well on the hoof but missed on the hook. Largely because our meat colour was to light, scoring 0 out of 10 from a total of 54 points which pretty much eliminates them. Dark meat colour scores 5 out of 10. All six of our steers had light meat colour and about half of all steers entered. Am wondering if the is something feed related we could change to affect this. They where pretty much grass finished with only a small amount of grain. Saw on the Tyson thread  that more of your show cattle are dark cutters, what other things effect meat colour.

What age were the steers?
Also with that many light colored carcasses, sounds like it Could Have been a processing issue (i.e.: too long from stun/stick to chill or poor chilling causing a rapid early pH decline).

More Grain = darker meat ??
The steers where about 19mths
Something at processing could be the problem. Steers would have been from all over the country with different diets and genetics so was surprised so many came up light coloured.

Did some research on this out of curiosity. Looks like Vit. E can be fed to increase myoglobin which in turn makes the nice cherry red color. Possibly a vit. E deficiency? Most info I found was on problems with darker cuts caused by long periods of stress and high levels of adrenalin pre slaughter. Maybe all the steers were just really "chill" lol  O0

Here are some interesting links that talk about meat evaluation and color. Never hears any of us to review what our business is really about

Not to try to side track this.... but....
Why do you show them with nose clips?
Its in the rules that they have to have nose clips, Think its probably because they are worried about how much work has been put into the steers and a large number of the competitors have done very little showing or even work with animals. The group I work with are at the start of an entry level ag certificate  with very little experience with animals. They work the steers one morning a week for about 10weeks. We haven't had any issues but I feel better with the safety of a nose clip if something did.

Thanks for your post Dozer, Seems dark colour is more common and easily explained. Maybe I should stir them up abit next year.

I would definitely make them explain their reasoning better to you and hold them accountable to educate contestants. From what little I could find on judging meat color it sounds like it is unfortunately subjective.  I found another link that goes in depth with Vit. E a little more. There is less info on Vit E and I think there is still much not understood about its working. It does help with muscle function and can play a part in white muscle disease but that is more a selenium thing.

Sounds like anyone competing in a carcass contest would benefit from supplementing Vit. E
