What weights does he need to be and when?
Are you going to try and hit winter/spring shows with him or county fairs this summer?
THIS WILL BE FOR COUNTY FAIRS SUMMER OF '08
If memory serves IL weighs steers in in Feb/Mar, from then to State Fair it's 170 days+/-. They have to have a 2.3#/day rate of gain to show so you need to put on 400#+/-.
YES, HE WILL BE WEIGHED THE FIRST WEEK OF MARCH.
4 months now would make him a May correct. This is going to put him 30-60 days behind a lot of the steers that he's going to be running against.
HE WAS BORN MAY 14...A TWIN WHO WAS REJECTED BY HIS MOTHER. SO IS HE EVEN FARTHER BEHIND?
Assuming all the above is correct I'd say that you've got to have him charging from here on. If you're going for later on I'd shoot for a 14% protien ration with a NEG of about 56-58 for now, this will grow frame & muscle but not get them too fat too quick. Try to have him weighing 750-800 there in March, then bump him to about a 60 NEG then about a 1 point/month jump from there. This is about what we shoot for on feedlot cattle.
WHAT IS NEG?
I don't know what you have access to for feedstuffs, but tell you're feed mill this is what you want to do and they should either be able to tell you what you need for feed or they should be able to call someone at corprate to figure it out. If they can't find someone else.
WILL DO.
DO NOT get talked into buying the "top shelf, high speed, this is what all the winners use" premix feed. Show cattle are still cattle, just because we're breaking them to lead and taking them to shows don't mean that they are some geneticly modified creature that can't make it work on conventional feed. The "show feeds" are designed to make them grow slow so they can make these calves hit more shows, I don't think that you can afford to let your calf grow that slow and make him anywhere close to where he needs to be for his end point.
