I know that there are a million threads about calving ease but I am really stuck on what to order for semen and I just can't seem to decide so thought I would ask again. I have 4 heifers to breed: a Dirty HairyXMaine, Eye CandyXMaineAng, I am LegendXAng and a SimAng. All of these heifers are out of commercial MainexAng and SimXAng cows that I have never had to pull any calves from. They weigh between 700 and 850 now. We will be breeding them the 1st of June. Should I go with Total Solution or something like Duff's Basic Instinct? Has anyone ever heard of any problems with Total Solution on heifers? Am I risking the well being of these heifers by thinking I can possibly get some saleable calves with their first calves? I have a very small heard of 20 and need all the good, saleable, show calves as possible but when almost 1/4 of your herd is heifers this becomes even harder.
