I was looking at the economics of finishing on grass vs. grain fed a couple years ago and after I crunched the numbers even with high grain prices it still looked to me that grain fed was more econmical because of the faster ADG and total carcass "cut weight" yield at the end. I seem to average about 375 lbs. meat off of my Angus, and Angus cross Hereford steers by about 12 to 14 months but I purchase of Limo cross steers from another guy every year and I had the same thing happened that others mentioned, they seem some what hard to get fat and seem like it takes 16 to 18 months of age to get them ready and I only get about 20 pounds more packaged weight after it is all said and done. But I know the feed lots make them work and I am guessing that they are controlling the DMI of the bulky stuff like hay? On the other hand, I'm thinking I don't want to buy any more of these Limos', I don't have a high tech feeding op. and just don't think I should have to be feeding them for a year. Plus this guy wants $1.18 for them and he has about a dozen at 600 lbs.
