Calves are naturally curious, and so if you put a pail or tank of water it can reach in its pen or where it can sniff at it and the water, it may get the calf to start drinking water. If not, put some water in the bottle and see if he'll drink from it. Try and do it near the water source. Often calves figure out themselves how to get water, and often don't need human assistance to get them to drink it. Calves that are with their mothers will often sample the same thing that their dams drink from; this is how the cows teach their calves to drink water.
Any time, really. A calf that is with his dam will often sample or taste the same thing she's drinking by the time he's around a month old. Bottle babies can have access to water around the same age.
Both drink at the same rate, actually. But it really depends on the individual calf and how thirsty it is.
As far as I know, yes. I've given them water after them having drank milk before, though I'd imagine that the amount would depend on the size and age of the calf. Might not be a good idea if the calf is too young, though I'm sure it's fine.
Most farmed calves actually drink milk replacer so that the mothers can be farmed for the dairy milk that humans choose to consume. This also means the calves are often separated from their mothers at a very early age.
A calf will butt it's mother's udder. This will encourage the milk to let down so that the calf can drink.
A calf that has just been weaned from its mother. It's a calf that no longer relies on its mothers milk for food and growth, but is now dependent on hay, silage, grain, water and mineral for its source of food.
Depends on how old the calf is, but milk replacer mixed with water is what you can feed a baby calf. Also allow it access to hay or grass, grain, and water.
i think its 75%bz calf 70%
That all depends on the age and weight of the calf. Typically a calf should recieve 10% of its body weight in milk replacer per day.
Mother's milk is enough for at least week, but from then onwards, clean fresh water should always be provided, particularly from the time that the calf begins to nibble solid food. This is because milk goes into one of the compartments in calf's stomach (via their 'oesophageal tube' which opens when they tilt their head back to take milk) and solid food, plus the water to help digest it, goes into another part of the stomach.
Calf.
A newborn calf requires 6 L of colostrum within 12 hours of being born, preferably 4 L (1 gal.) immediately after birth (or within 4 hours) and 2 L (0.5 gal.) a few hours after. Basically, newborn calves shouldn't be given milk right after birth. They need colostrum because it contains crucial antibodies and immunoglobins that are needed for its suppressed immune system. Colostrum is, really, a maternal transfer of antibodies from the dam to the calf. "Normal" milk shouldn't be introduced to a calf (gradually) until 24 to 36 hours after birth.
A calf less than 3 months old is still not ruminating, so it should be fed a high quality milk replacer several times a day. You should also provide clean drinking water (if you wouldn't drink it, it's not clean enough) and good quality grass hay for the calf to munch on.
