You cannot make a cow. Feed is to be fed to a cow, not to make one.

it depends on the brand/type of cow feed...could be anywhere from $10-50
More information such as type of feed (hay, grain, silage), type of cow (dairy or beef) and period of pregnancy (first, mid or last gestation) is needed before this question can be answered.
how your cow and goats eat
rBGH, or bovine growth hormones.
It all depends on what's available in your area and what breed, type and size of milking cow you own. It also depends on what feed is already being fed to your animal.
If you are feeding up this "cow" for slaughter, then it should get around 20 to 25 lbs per day, along with hay and/or grass.
Maintenance requirements are 2.5% of a cow's body weight in dry matter ration per day.
Humans don't digest all plant material very well. If you can get nutrition out of it, it's more efficient if you can eat the plant material directly. If you have to feed it to a cow, and then eat the cow, a lot of the nutrition will be lost in the transition. But if you can't get nutrition out of it, and the cow can, then feeding it to a cow would be sensible.
Depending on age between 1-5 yrs. of age you should never feed more than 10 cups to any one cow. At 1 year feed one cup 2 yrs 2-3cups 3 yrs 3-4cups and 5 and up can be fed more and more gradually until about 9-10 cups but feed slowly because to much grain can kill or make a cow sick.
It is if it's processed enough that the microbes in the cow's rumen can break it down and digest it. It would be a waste of money to feed if it's fed whole/unprocessed and not much nutrient can be gleaned from it by either the microbes or the cow.
