Cows produce calves. Calves, like all other baby mammals, rely on their mother's milk for nutrition. Thus, in order to satisfy this need, cows need to produce milk for their calves.
Cows and goats need to be fed on grass and oilseed cakes because grass and oilseed cakes are milk producing food so these help them to produce milk
Energy and protein. Cows need the energy for their bodies to produce milk and to keep them healthy. They are able to digest grass in their rumens to get the protein and energy for them that can be found in milk.
Not if they don't need to be milked, no. But, if you're hired to milk dairy cows, and Jerseys are among those cows that need to be milked, then the answer would be a very obvious yes.
Yes. Cows need to be healthy in order to produce a calf, give milk, and even live a good life. Vaccines and antibiotics are made available whenever an animal is in need of it, but shouldn't be used on an animal if she doesn't need it.
They might not move around much, but female cows need energy to help their calf grow inside them (if they are pregnant), and produce milk to feed their young.
Not necessarily. Cows produce milk to feed their calf. They're artificially inseminated to make them pregnant, and thus they produce the milk upto, and after the birth. Whatever food they eat - whether that's naturally-grown grass, or artificially produced feeds - gives them the energy, vitamins and minerals they need to produce the milk.
The original saying is "t*ts on a bull," which refers to something completely preposterous. Bulls are male cows, which do not produce milk, so they have no need for such milk producing organs.
Yes, it is much healthier. Grass fed cows produce about 6 times the amount of CLA than grain fed cows do. CLA(conjugated linoleic acid) is a heart healthy fat. Grass fed milk also has a high amount of omega-3 fatty acids and is loaded with vitamins.
As many as what a breeder needs. Bulls don't produce semen that need to be collected like with cows that produce milk. A bull can fill thousands of straws per year if need be, depending on the demand for straws from that particular bull.
No. Cows don't need to drink milk: they drink water, not milk.
Cows are being tested because Scientists need it to test it for MILK
