[QUOTE="Lorenzo, post: 295583, member: 5104"] Thanks everyone for the answers. Heifers are good for embryo transfer because their pregnacy rate is very good (obviously if their corporal condition is ok), the only problem and I am not so sure there is such a problem, is that IVF embryos sometimes are a little bigger and maybe a big adult cow will perform better when that calf is born. I am paying the sexed straws between 70 and 77 dollars each. In tha lab I can fertilze several cows at the same time with one single straw so that is an advantage when using expensive semen but as the pregnacy rate of tha sexed semen is lower is difficult to know what will happen. Nothing as a first hand experience test in the real world so I will give you all the data after the test. After the insemination with normal semen I am having 40% of viable IVF embryos so lets see what % I will achieve with the sexed one..... Right now I am in the middle of the "season" and thanks God I am fully booked but I think I will be able to do the testing around the 20th of december. Lorenzo [/QUOTE]
