Supplement Help

I have some Heifers and Bulls that I need to push; I have 45 days left is that enough time to try and push them with some kind of supplement to increase muscle and fat? Also types of supplements will help.

as far as fat goes i would be cooking corn and barley asap. that should do the trick. feed about 3 pounds morning and night if they need alot I would do 2 ibs corn 1 ibs barley otherwise just keep it at 1.5 ibs a piece. Muscle you can get a number of supplments from sullivans but make sure they are able to get plenty of exercise.
