I believe you said your feeding your calf with about 20 other head? If its possible he needs his own feed, and by that I mean you need to know exactly how many pounds HE is actually getting. That is the only way you will know his daily rate of gain. If he needs a buddy to eat with pick out a smaller calf that likes to eat too to stall him with. I personally have found that a goat is the best way to feed a calf if you only have one. (they need a little competition to make them eat well) The goat eats very little and it keeps the calf company too. Do you have an advisor? County Extention agent or FFA teacher? If you do, you need to use them! That is what they are there for. IF they are not familiar with show cattle THEY need to help you find someone close by whom can help, hopefully with some hands on stuff...I believe you have the drive and ability to do well on your own but to suceed and excel you really need some hands on help especially with a project this large. Purina had a video out once about feeding and grooming show cattle, I actually watched this dvd and that was my first "teacher" from there I was lucky enough to get an extention agent whom was a show cattle guy and I learned everything I could from him. Would someone please help this young lady find an advisor?
