Calves have a fold in front of the reticulum that is activated when the calf is positioned to ingest milk; this fold forms a tube that becomes a temporary extension of the esophagus, allowing the milk to flow through this "esophageal groove" by-passing the rumen completely and emptying into the abomasum, the true stomach of cattle. Digestion of milk in the abomasum instead of the rumen is critical to the health and growth of the calf. Nature makes sure milk goes into the abomasum even after the rumen is fully developed. Calves process milk in their true stomach much like any monogastric does, which digests the milk giving them the protein and nutrients they need for their growing bodies. Most calves start eating forage by their first week, and are chewing their cud by the time they are 2 weeks old. Their rumen fully matures when they reach 3 months of age.
Calves that are suckling milk from cows which would be their mothers.
Calves suckle from their mother's udder, which is the organ where milk is generated and obtained by the calf or the milk machine (if the cow's a dairy cow).
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.
Breeding dairy cows produces calves which subsequently makes them produce more milk in the next production year. Calves are also raised as replacements (if they are heifers) for the other cows, as these calves have been selected, through the process of sire selection, for giving more milk per year when they mature into cows.
As long as the milk is straight from the cow, not the stuff that has been modified by humans (i.e., milk that has undergone pasteurization). Calves are best put with a nurse cow than if they were bottle fed.
The reason cattle produce milk in the first place is to feed calves, not to feed people. Frisian cows in the wild--if such they be--"get rid of" their milk by letting calves suckle it.
its mother milk
Play, suckle milk, and sleep.
Calves, or baby manatees, drink milk from under the mom's flipper or fin.
If bred, milk and baby calves.
TLC and milk.
Bobby calves are those calves that are meant to be slaughtered when they're only a few days old. These comprise of mostly dairy calves that are not needed or culled from the milk cow herd and are used for veal meat.
