[QUOTE="Jdunn55, post: 7184680, member: 81760"] Yes, sorry! 1 in 4 chance to have twin heifers, 50% chance to have mixed and 25% twin bulls. Cow eggs dont split. That would result in identical twins, as of now theres only 3 species of animals known to be capable of having identical twins: humans, armadillo's and dogs (although there has only ever been 1 recorded case of identical dogs). All twins from cows are due to 2 eggs being released by the cow and being fertilised by 2 sperm. Full siblings but not identical. Which is why one is red and one is black. What makes a free Martin is that when the calves are attached to the cow through the umbilical cord there is a chance that the Male hormones can "backtrack" and end up getting to the female through her umbilical cord. Statistically, less than 10% of heifer calves from mixed twins are capable of breeding. Wether you have money to waste is up to you! Worst come worst you have a heifer to put in the freezer! Hope that helps [/QUOTE]
