When you really want a bull to be homozygous, he'll probably be heterozygous.
Murphy's law also dictates that your best bullcalf will be scurred.

If you think about this one for a minute, there might be another reason [not Murphy's law] the best bull calf always scurred. It may be a scurred bull geneticly the better bull. Here's a couple of scurred bulls you might know, CS Boomer 29F, Wrangler 19D, H 8E Embracer 8006, OR Dom 549 F243, and althougth he's not listed as having scurs, I do believe Remitall Keynote 20X was also a scurred bull.

One of the old time breeders of quailty Polled Herefords lamented the culling of animals strictly because they were scurred. He maintained that frequently the scurred animals were superior to those that weren;t scurred but the single trait selection for smooth polled may have prevented the development of some truly superior cattle.

Murphy's law also dictates that your best bullcalf will be scurred. Apart from seeing the calves and doing the DNA work you can look at the pedigree and if you don't see any horned animals in the last 5 generations the bull is very likely homozygous, but you'll never really know untill he is either proven or DNA tested.
Part of the reason scurred bulls were culled is because they believed only heterozygous bulls can be scurred.
Here is a link to rather old research on this.
