It's hard to tell what you're trying to ask because either you may be referring to feeding the calf roughage, or "eating" milk. The calf will be able to eat the roughage if it's hungry enough, as many a thrifty calf with intense curiousity (as is with most calves) will find the hay and grain to eat on its own.
As for the milk, that's a different story. You will have a harder time getting a calf to drink from a bottle or bucket than one that is newborn because he will be very used to suckling from his momma but not from a bottle. Even the taste of the milk replacer isn't the same as the milk straight from his momma. Either way, you will have to restrain him, and try to get him to suckle from a bottle at first. You can't do it by yourself, as you will need someone to help you hold him while you teach him to accept the bottle or bucket. It will take a while for him to get used to it, so be persistant and don't give up.
its mother milk
Tube feed it and find out WHY he won't eat from his dam.
A baby rhinoceros is raised by its mother. The mother provides milk for the calf until it is old enough to eat only solid food. She also protects her calf from predators.
In nature the calf would suckle the cow (drinking its milk) until it could eat grass. In industrial farming the calf will quickly be switched to formula and the milk collected and sold to us humans instead.
They have to be bottle fed milk replacer that is specially made for them. Milk replacer usually comes in a powder formula which is mixed with water and given to the calf accordingly. However, milk replacer doesn't need to be given to the orphaned calf if the owner has a cow that can be used as a surrogate mother for the calf.
A newborn calf needs to have his milk every two to three hours.
The mother usually cleans the calf with its tongue such as a cat. The mother giraffe will then use its long neck to lift the calf to its feet. It does this by transforming its neck into a lasso type contraption. Once the calf is up and standing it will be beaten into the heard if it's male and sexed in if female. Once the giraffe is officially part of the heard it will start its life as a contributing member of society.
Are you referring to feed like hay and grain, or milk? Please be more specific so the question can actually be answered.
usually not... but a mother rabbit would eat her baby if it died
the average Irish calf can eat between 5 and 6 leprecauns per day with some light water refreshment
They learn to fend for themselves or die.
Killer whales will actively hunt immature blue whales, who stand no chance against their instincts and hunting abilities. The hunt can go on for hours, constantly trying to separate the young calf from it's mother. Eventually the calf becomes too tired and disorientated from the attack, causing it to eventually separate from it's mother. The mother tired and out numbered looses the battle to save her calf. In most cases after killing a blue whale calf, all they take from the carcass is the tongue. Yes they do, but they usually attack as a group until the blue whale dies.
