Many companies feed cattle feed supplimented with beef by products like ground entrails and brains. This is a good source of protein and builds muscle mass quickly; unfortunately with the advent of mad cow disease, the practice of feeding cattle the byproducts of their slaughter is frowned upon and banned is some areas. Mad cow disease is a result of a prion being introduced into a healthy bovine by consuming spinal or brain tissue of an infected one.
So the best thing to feed a cow is hay, straw, a little grain, and/or pasture when it is available. Do not restrict a cow from feeding out on pasture, as a grass-based diet is much healthier for her than a grain-based diet with animal-byproducts mixed in. However, in the winter time when there is no pasture to eat (or the snow is too deep to root around in for dried grasses), you have to feed hay or straw, according to her health needs. Be careful about feeding straw though, because you could end up starving her instead of doing her good if the straw is too low in nutrients and too high in fibre and cellulose. When she's lactating, she needs twice the nutrition she would if she were not pregnant and not lactating.
And, lastly, DO NOT RESTRICT SALT AND MINERAL. These are crucial to a cow's health, as a cow (or any animal) cannot go without salt or else she will die. Other minerals like copper, iron, cobalt, iodine, selenium, magnesium, manganese, etc. THey all play an important role in her health, bodily functions, digestive system, neurological, reproductive, immune, and other functions.
No.
Maintenance requirements are 2.5% of a cow's body weight in dry matter ration per day.
That depends on the type of cow. A dairy cow is able to feed four at one time, whereas a beef cow will be only able to feed one calf at a time--two if she's a really good producer or has a significant amount of dairy influence in her.
A calf (or baby cow) is the reason that the beef and dairy industries have not crashed. They are the future beef and milk producers, so in short answer they will feed you.
the average beef cow is 1,333lbs
None. Cows eat grass, hay, silage and grain, not any sort of animal meat like "beef nut."
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.
horses do not have beef. beef is on a cow.
Only if she's a dairy cow, like a Holstein or Jersey or some sort of dairy cross, like Holsetin-Jersey cross or Swiss-Jersey or Swiss-Holstein cross. Those type of cows can nurse up to four calves at once, with one calf on each tit. A beef cow or beef-dairy cross cow will not be able to feed three calves at once, only one; dairy-beef cross cows may be able to get away with feeding two at the most; occasionally three if she's a high-producing cow for a beef-dairy cross.
The largest single cost in a beef cow operation is most likely always to be feed. However, if you plan to have a special operation where practices such as in vitro are practiced then you are going to have a higher cost for the reproductive practices.
