hi. havent been on for a while. glad to be back. when we got our black max bull in '09 he bred the entire herd. our '10 calves came in early june-early august. when they were 2 months each calf developed curly yellow hair in their ears. the following breeding season we turned out our bull as well as 2 others with our cows and 30 of our friends cows. they came from late march-late june. 6 of the friends cows had calves which developed yellow ear hairs and 12 of our calves had them too. when we DNA'ed the calves all the ones with yellow ear hair belonged to our bull. last year we didnt use him and we still had several calves with yellow ears. when DNA'ed none were his. im kinda confused now. anything would be nice.
 
Hi longhorn, i have been gone awhile too, i hope the summer has been good to you!

One possibity could be from mineral deficency, sometimes that can cause the hair to bleach out, ie making a black calf look brown or other color calves to be a bit off. This could be due to soil type on your ranch, which could explain why the batch of calves after him still had the yellow hair, just a thought!

Do the bulls have any long horn in them?
None. Only our cows are longhorn.

great ideas but the only yellow on the calves is in their ears. We leave minerals out for them to lick on but I don't know if all of them licked it. When I checked the records the calves with yellow ear hair were out of his daughters and a sister. They might just be passed on from him? I don't know.

Could be from some of the LH genes way back in the cows.
That's what I thought too. His sister is a fullblood black max though and one of his daughters is out of a black angus cow as well. Could be from the black max genes maybe. They are really nice calves though lol
