When a person is normal, but far from animal husbandry, he hears that there is a cow with a hole in its side, then he perceives such information as a joke. It is akin to a well-known song about a hedgehog who was whistling a hole in the right side. Nevertheless, everything is real, although at first it is unusual. Next, we will analyze in detail what the cows are doing a hole in the side, how much the animal itself needs it, and how the surgery should be performed in general terms.
How vets explain the need for surgery
Indeed, seeing such a person experiences a light shock. The first thought that comes to mind is why cows have holes in their sides. After all, they lived without such an upgrade for thousands of years, and everything seemed to be normal.
It turns out that the matter here is not at all the whim of some advanced farmer who decided to do a piercing with his cow in order to attract tourists to the farm. And believe me, the cow is not ill with anything. Moreover, an animal equipped with a valve in its side, according to farmers, breeders and veterinarians, feels great, much better than a simple cow.
The fact is that a cow stomach is a complex “factory” for processing different types of feed. When switching from a dry winter diet to succulent pasture grass, this factory often fails, to the point that the cow can die.
Previously, this problem was solved by surgical intervention, an incision was made in the peritoneum, through which gases were released, a valve is now being put, or a fistula in Latin.
The practical side of the issue
Naturally, no adult, sane person would believe that practical farmers in powerful livestock farms make such operations to their cows only from the desire to rid the cows of gases. After all, the procedure is expensive, but then why do cows have a hole in their side, and why are these operations done en masse?
If you dig a little deeper, it turns out that direct access to the scar (one of the sectors of the cow's stomach) allows you to solve a lot of tasks simultaneously:
- at any time you can do an analysis of microflora;
- if dysbacteriosis has been identified, then it is possible to add or select, on the contrary, a part of the microflora;
- solution of the problem with excess gas when changing the diet of feed;
- necessary food additives can be dosed directly into the stomach, which greatly increases their effectiveness;
- through the opening it is possible to carry out local operations on nearby organs quickly and practically painlessly for the animal.
As practice has shown, animals with fistula stably gain the necessary weight, give more milk and are less susceptible to diseases.
The first to fight the fistula rushed animal advocates. Green
It is considered unacceptable blasphemy surgical intervention in the body of a healthy animal. At the same time, the situation when a cow really suffers from an oversupply of gases and has to be cut, for some reason does not bother them.
The same animal rights activists organize pickets near specialized farms where holes are made in the sides of the entire population and fistulas are implanted. After that, through complex experiments and analyzes, more efficient feeds are developed. Although cows, most likely, are not against improving their diet as a whole.
Vegetarians were not left aside, they feel sorry for the leaky cows. Although, it would seem, they should not be against it, because many such studies are conducted with the aim of creating protein products of non-animal origin.
The only really controversial question is whether it is worth driving children to such farms. The Slavic world strongly opposes. While Western “educators” consider this to be normal.
Preparing the animal for surgery
Implantation, or cannulation, can be carried out only by adults, and cows aged 2.5 to 3 years who have already become cowards. It is undesirable to put the valve to young individuals. After all, until the phase of active growth has stopped, the probability of an unpredictable fistula displacement remains.
Approximately 2 weeks before the intended operation, the reaction of the cow to brucellosis, leukemia, emphysematous carbuncle, anthrax, tuberculosis and a number of other dangerous infectious diseases is checked. And this should be done regardless of the presence or absence of vaccinations.
At the time of the surgery, the cow should be of average fatness. Feed the animal stopped 12 hours before the procedure. There are no restrictions on water, although many veterinarians do not recommend drinking cows heavily before surgery.
As for vaccinations, they are stopped one month before the operation, and the vaccination schedule can be resumed no earlier than 2 months after the intervention.
Stages of operation
To relieve stress, a muscle relaxant is injected into a cow, for example, Rompun or Rometar. Next, the animal is fixed in the machine. At the site of implantation of the fistula, a perirenal blockade is made with novocaine or any analgesic.
The implantation point is located approximately 7-10 cm below the edge of the processes of the vertebrae of the lumbar region and 10 cm beyond the extreme edge. Roughly - this is the level of McLock. Marked circle should be slightly less than the diameter of the cannula. The sequence of actions is approximately as follows:
- The skin is cut.
- Then comes the stupid way of breeding muscles.
- The peritoneum is dissected, after which a hole is cut.
- Captures the wall of the scar.
- The scar is tightened to the edges of the skin.
- Edges of a hem and skin are sewed, here it is important not to capture muscles.
- The wall of the pancreas is cut.
- Its edges are sewn with leather.
That the cannula became elastic it warms up. Initially it is recommended to put a three-inch cannula.
Now such operations are not classified as particularly difficult. If qualified, the district veterinarian may conduct them. If done correctly, then in an animal with normal immunity, the wound heals in about a month.
The first 5 days after surgery, a course of antibiotics is punctured. Self-activity is not allowed here, the type and dosage of drugs prescribed by a veterinarian. The choice of antibiotic depends on the condition of the animal, its weight, climatic zone and, of course, on the quality of the operation itself.
The tumor around the wound will begin to subside no sooner than a week later. In order to avoid suppuration all this time, the wound should be regularly cleaned with a disinfectant solution.
Agree, the theme of the hole in the side of the cow is ambiguous. Share this information with friends on social networks and, for sure, a very interesting discussion will flare up in the comments, the ancestor of which will be you.
