The cob will have around 4% protein, corn around 9.9%. You will need 70 pounds of ear corn for a bushel. So you will have about a 8.72% protein. That may not help much but I'm not a cow calf man.rjbovine":8t5x0t64 said:
Use the information that inbredredneck provided. Then get your hay tested since that will be your base feed. A cow nursing a calf needs a ration that will be 12 to 13 percent crude protein. How much protein that needs to be added to the ground ear corn will depend on the quality of the hay. How much to feed depends on cow weight and body condition score. Figure that the cow will eat 2 to 2.5 percent of her body weight each day.inbredredneck":3qgzmlp8 said:

years of on site trials, and just recently testing some of this years corn more than anything.thendrix":2q1pumxb said:
You just have to remember that there are 3 components to an ear of corn. The shuck or husk as some call it, the grain and the cob. Each has a different nutrient value for protein as well as other things. Knowing these and what % of the whole each represents allows you to calculate the weighted average of the crude protein. I use numbers different from those IBN used but the end result is not much different. I'd calculate the protein for the ground ear corn at 7.8% to 8% overall and use that to balance with teh hay and any additional supplement you might need. If your hay is low quality you'll definitely want to add a protein supplement to the ground ear corn.thendrix":2jv38qko said:
T Bred I should have mentioned that all our corn picked clean this year, and shelled severely at the head. So any ear corn here is without husk. I would guess 4 to 7 bushels remained in every field via harvest loss at the header.TexasBred":3c4xpqei said:
