A calf's rumen starts growing after the calf is born, and often has a fully functional rumen by the time he's around 3 months of age. By this time, he's about as dependent on his dam's milk supply as he is on the forage that his dam is or has taught him to eat. Milk production (as a way of weaning him) decreases by the time he's 3 months of age, and by the time he gets weaned, which is around 6 to 10 months of age, milk is in low supply and he's eating more forage than suckling from his dam.

How long does it take for a calf's rumen to start working?
The calf's rumen doesn't become fully functional until it is around 3 to 4 months of age. From birth until this time the rumen is underdeveloped and in the growing and developing stages. It is present when the calf is born, just not as fully functional as with a bovine that has been weaned and on forages alone or fully matured.
What stomach chamber doesn't work at birth for a calf?
The reticulum and rumen (and likely omasum) of a calf are underdeveloped at birth and do not reach full maturity until the calf is around 3 months of age, after the calf has began to eat grasses and/or grains like its mother. Calves will start eating the same things as their mother when they're only a week or two old. So that's not to say that there's particular compartments that do not work at birth, since all compartments are functional, it's just that they're not nearly as functional as that of an adult bovine. A calf makes the action of chewing cud at a few weeks of age, but is not actually chewing cud, since the rumen is not functional enough to enable rumenation. Young calves have a special tube-like structure called the oesophageal (or esophageal) groove which directs milk straight from the oesophagus to the abomasum. This is the final (fourth) stomach chamber of the calf. This means that milk bypasses the reticulum, rumen, and omasum (to a lesser extent). The oesphageal tube begins to disappear when the reticulo-rumen nearly reaches maturation, and when the calf becomes less dependent on milk and more on forages. The groove pretty much disappears by the time the calf reaches a point where it is no longer considered a calf, which would be at yearling stage.
How does the esophageal groove in the calf work?
In the calf, the esphageal groove works by contracting muscles in such a way so that the fluid (being milk) that the calf drinks by-passes the rumen and heads straight for the abomasum. The calf's head as to be tilted up and out in order for the groove to properly work. As the calf ages and the rumen reaches maturity, this groove disappears.
What is the Average weight of a 1 month old beef calf?
That all depends on what breed that beef calf is. A 1 month old beef calf can weigh anywhere from 80 lbs to over 200 lbs or more.
How do you puncture a hole in the rumen of a calf to relieve bloat?
A temporary rumen puncture is done using a needle called a 'trocar needle'. It's pushed into the rumen (just in front of the hip bone) on the left hand side. It's a hard push, but it should be done quickly so try not to hesitate.If you do not have access to a trocar, you can also use a sharp pocket knife to puncture a hole in the rumen wall to relieve pressure.However, puncturing a whole in the rumen wall from the outside should be a last-ditch effort to rid the calf of bloat. You should try to drench the calf first with mineral oil or dish detergent to relieve bloat before going ahead and puncturing a hole in the rumen.
What kind of meat does a calf have?

What are the five nutrients a beef calf needs in its diet to stay healthy?
The five nutrients a calf (or any bovine) needs in its diet to stay healthy are:WaterProtein (plant form and from the microbes in the rumen)Energy (form of carbohydrates)Minerals (such as cobalt, iodine, iron, selenium, copper, magnesium, calcium, phosphorus, etc.)Vitamins (such as A, D, E, and K vitamins)
