Bottom Line
December, 13 2018
Bottom line is that IVF changed the purebred market because that with conventional ET, only a few rare donors would produce over a hundred offspring and ½ or more would be bull calves. With IVF many more can produce high numbers of calves and all heifers if desired. Supply and demand dictate that if there are more daughters of a great cow than the market will absorb the price goes below the cost of production and we have seen that happen many times. Before sexed semen, big dairies would buy large numbers of replacements somewhere to expand, with sexed semen they can grow internally if and when they want to. The genetic boost to the nations cow herd should not be under estimated either. The big dairies make calves from bulls with great genetic merit with sexed semen, I assure you, few of them are using the “show bulls” to lead them forward. Looking at the list on Holstein’s website of “Highest Registry Activity by Bull” the first “show bull” shows up in the #23 spot and he would be not show up at all if the list was pure commercial.
