You have around 125 days, from the time you posted the pictures, until your show, if he gains around 2.5 pounds a day until then he will weigh 1442. Most calves slow down when they start reaching their potential finished weight, so I would continue to pour the feed to him and monitor his gain if he is gaining more than 2-2.5 a day over a 2 week period then you might want to slow him down, if he is in that range just keep feeding him. Make sure you weigh him at the same time each time you weigh him.
As he starts to get that look, the fat around his tail head and his ribs are covered and smooth, you want to start cutting back on the grain and add filler, we feed a beet pulp oat mix with the grain. The more you have to cut back on the grain the more additives you will need, we will add Fast Fat and Calf-Manna to make sure he gets the fat and protein he needs to maintain his condition.
Your target should be around 1400, cattle can loose 30 to 40 pounds on the trip to the fair grounds limit his feed and water the night before you go to the fair( 2 gallons water 6 pounds of feed and hay) nothing the next day until after you weigh. If you have a weigh back at your fair you should be OK if it is 5 percent the calf could weigh 1350 and be 1415 and be under the percentage.
Good luck
