If a guy wanted to take his cows frame size from 7 to 3-4;what do you think if a guy used a ''larger'' lowline.It would only be used on hiefers, it should make easy tme calving hiefers.One that is a 1 frame.If the calves average frame 3-4;differance between 7-1frame.Keep hiefers out of this mateing.Could this be done in one generation instead of 5 or 6 generations of useing 3-4 frame bulls.I have some big 1500-1600lb cows.I also have a handful of 4 frames that weigh 1200 in good condition.It seems there isn't much differance in the calves at weaning.I've also noticed the smaller ones are out grazing corn stalks and the bigger ones are by the hay feeder.
