"Straw Chasers" Good or bad for the industry?

Stocking rate and fertility are the two biggest drivers of herd revenue. The costs to achieve both drive profitability.

Prepotency is not derived from heterosis. Heterosis is derived from presidency.

One can make HUGE progress in their herd by growing their own bulls... the key is having the right selection criteria.

Prepotency is derived from linebreeding. Consistency is derived from prepotency.
Heterosis IS NOT derived from prepotency.
Heterosis IS derived from differences between the genetics of Dam and Sire.

Yes; heterosis might be stronger if the parent stock is inbred, but only because there is more for the heterosis to "cure". Cross an outcrossed bull (breed A) with an outcrossed cow (breed B), or a linebred bull (breed A) with a linebred cow (breed B), the progeny in both crosses will be at the same production level, but the cross from linebred parents will be more elevated from its parents production level. Thus, the fact that some of these cattle were linebred did not make any extra production.

I've got to quit responding to threads from my phone... Here's what I meant to say:

Prepotency is not derived from heterozygosity, but homozygosity.

True, but the offspring would probably have been more uniform.

Yes it would be more uniform/consistent, and much more predictable.
Ideally such F1 progeny needs very little culling because the linebreeders have already removed must of the dirt from the genepool, as opposed to the regular outcross breeders.
