I'm really new so not a lot of experience to draw on. Bought two bred heifers...both are Angus-sired..bred to low birth weight registered angus bull. Both are angus sired heifers...but one is large frame, one is medium frame. Both exposed to bull 3/17 to 4/14, 2002. The medium framed one showed for a long time, bagged up for about 2 weeks and then had a beautiful calf. The large framed one has not bagged up yet and is not really "showing" like the other one. Both are from the same small herd and were preg checked by the vet and cert. before the sale. Are there some cows that really do not show as much because of their frame size? My gest. calendar shows 1/24 as the date if she was bred the last day! Thanks!
