TMR = Total Mixed Ration. It is useful only when a cow is being confined in a barn, and not on pasture. So if you are referring to a large herd of dairy cattle that are confined in a barn, then yes it is good to feed them TMRs. But it defeats its purpose when you are grazing the cattle out on pasture.
They eat hay (alfalfa, timothy etc) TMR (total mixed ration of soy beans, hay, silage etc), grain, corn etc.
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.
Jerseys would eat what a typical dairy cow would eat, being a TMR ration or grazing grass out on pasture. See the related question below for a more detailed answer.
Femininity, milking ability, good mothering ability, conversion of feed, and good reproductive ability. All these points are important in having a good cow that will raise a good calf, breed back on time, and keep feed costs down.
The basic diet of a dairy cow is a TMR (total mixed ration) this ration usually consists of soybean, silage, and hay (alfa alfa), this ration is mixed in a large machine and delivered to the manger for the cow to eat.
You cannot make a cow. Feed is to be fed to a cow, not to make one.
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.
yes the BMR must be lower than the TMR
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.
It really depends on the type of feed she's fed. It will take a lot longer for a cow to feel full on good or excellent quality feed than poor quality feed. On average, it can take around three to four hours of eating until a cow feels full.
No.
