[QUOTE="KNERSIE, post: 585249, member: 4353"] I'm sure the feedlot folks like somn and the likes are more qualified to give advice, but since no-one else has replied... Calves of that age can utelise a slightly higher protein feed, they are also typically just weaned and more proned to stress related illnesses and digestive upsets. To help prevent the digestive upsets the protein source should start out as a natural source like sunflower oilcake, Canola oilcake, soybean hulls, etc and not a NPN source like urea. After an adaption period of about 4 weeks that can slowly be replaced with urea as a protein source if the difference in price really justifies it. So in short start out at around 16% protein, that can slowly be reduced to about 12% as the energy increases. You need to aim to get to about 70-72% TDN in the ration. In a TMR start with about 50% alfalfa or good quality grass hay, the protein supplement and the rest either rolled or crushed barley or corn and a buffered medicated feedlot concentrate. There are alot of commercial feedlot concentrates with mixing intructions for a variety of rations mixing from a cafeteria system to a TMR. The hay part can slowly be reduced to about 25 % and the corn increased. I prefer a cafeteria system myself and I just go with the mixes according to the mixing intruction on the sack of concentrate, if you were in SA I would have been better able to help you, but I have no idea what products you have available there. Remember that TMR are never supposed to run out and need to be available adlib at all times. [/QUOTE]
