we just worked the heard/ we goofed and waited 8 mo's between workings. The bull calve in question gained 402 lb in 8 mo's (he's now 21 mo's.) Feeding 1-2% body weight w/14-16% protien (corn & beef supplement). Since I'm a green horn...is this an unusually high weight gain? Also am I feeding too much/ what is an aggressive amount of feed? (using no fillers such as cotton seed hulls or hay in the corn- just quality ground corn and supplement) For what it's worth the heard is registered black angus.
