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 do you give a bloated calf?
Swiftest way if a calf is bloating badly is to tube it with mineral oil. Another method, if the calf has mild bloat, is to chase it around and help get the stomach moving to expel the gas. If the bloating is severe, then a trocar has to be used to puncture a hole in the rumen to relieve the gas.
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.
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.
Can you feed bread to a calf?
Yes. But only in moderation, as it is very high in carbohydrates and starch, and the calf could easily bloat on it if he eats too much of it.
When does a beef calf have a functional rumen?
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.
Why can young calves not ruminate?
Because their rumen isn't fully developed. Calves are born as monogastrics, with the other three chambers as only sacs of useless skin along with their abomasum or their true stomach, which resembles the stomach of all other omnivores and carnivores. The rumen doesn't start to begin to develop until a week after the calf is born; the rumen completes development by the time the calf's 3 to 4 months old. So when calves suckle the milk from their mothers, the milk is directed straight to their true stomach, which is designed to use and break down the proteins, amino acids and nutrients from the milk (containing animal proteins!) for the calf's growth and development. The rumen doesn't start developing until the calf starts to consume or "taste test" forages that its mother eats, which is by the time a calf is around a week old.
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.
Which side does a cow carry a calf on?
Both sides, but it'll lean a little more to the right than the left. The rumen is on the left side of the cow.
Which compartment in the ruminant is nearest to the oesophagus?
The abomasum, this is the 'true" stomach which is able to easily absorb the number of antibodies from the colostrum and the high amounts of protein. The rumen and remaining stomachs will begin to develop once the calf begins to intake roughages (hay and grains). To learn more about the development and function of the Rumen, view the attached related link.
What is the size of a pregnant cow uterus?
Without a calf (or unbred), it's 1/3 larger than a basket ball. With a calf inside that is almost full term, the uterus can be about the same size as her rumen, which is as big as a 25 gal. barrel.
How much grazing does a calf need for one day?
As much or long as it likes and you want. Seriously, you can have your calf graze as much as you wish or it wishes, it's not like feeding grain to it and risking it getting bloat from feeding too much grain.
How many stomachs does a calf have when it's born?
Four, just like his mother, but the first three (the rumen, reticulum and omasum) are under-developed, unlike his true stomach, the abomasum.
