I just started raising four Longhorns, three as pets and one for food. The 5 month old steer has a date with the butcher the second week of January. I've been feeding him 7-8 lbs of 20% protein cattle cubes from Tractor Supply along with coastal bermuda hay each day. I've got him penned up in a 20'x20' enclosure. I grew up on a grain farm so I'm a little green when it comes to raising cattle. Is there something else I should be feeding him to fatten him up more? I only have access to feed from Tractor Supply and the local feed store. Any advice would be appreciated.
