Depends on age, body weight, body condition, nutritional needs, breed, and how the "cow" is managed, even if it is a cow that we are talking about here (i.e., a female mature bovine that has at least 2 calves). For cows that are underweight and need to gain weight, feeding at 1% of their body weight is sufficient. This is the same for bulls and replacement heifers. For backgrounding steers, 1.5% to 2% of their bodyweight is desirable; for finisher cattle, 3% of their body weight should be fed to them.
There are also other alternatives to feeding grain. Some producers don't even feed grain and instead feed good quality hay and other supplements like range cubes, beet pulp, bread, etc., to increase weight gain in cattle.
Grain should only be given if your animals are thin and need to increase their weight. If they are in a good condition (can't really see their bones) or fat (can't see any bony protrusions at all) then don't bother graining them; you're just wasting money on feed you don't need.
Ten pounds per cow
45% of the bag every two days
The feed it eats (grass, hay, grain, silage). Grain and silage is higher in energy (in the form of fats) than other feed sources.
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.
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.
You cannot make a cow. Feed is to be fed to a cow, not to make one.
None. Cows eat grass, hay, silage and grain, not any sort of animal meat like "beef nut."
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.
That all depends on the individual cow and what that cow is fed. Feed efficiency is measured by dividing the amount of gain an animal experiences by the amount of feed it is fed. Feed efficiency can be influenced by the amount of grain put in a diet, the hormonal implants an animal recieves, the ionophores included in a feed, and the animal's genetics and breeding. Thus, feed efficiency itself is highly variable and tends to be inconsistent with each individual animal. This is because there are feed efficiency calculations which deem an animal suitable to be finished on a grain-based diet, and feed efficiency calculations that deem an animal suitable to be finished on grass. There is much discussion on feed efficiency of beef cattle, so much that it would be worthwhile to visit some or all of the related links posted below.
Enough to fill a cow!!
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.
Depending on the quality of the grass. It may if the quality is good. A new mother cow should have extra feed for the milk in the form of grain.
