Chapter 18: Castration
After feeding the pigs in the morning, Tian Fei suddenly found that he still had something to do.
There are so many boars in the pig farm, Tian Fei has not yet been castrated.
Generally, if you raise fattening pigs, the boars need to be castrated, and some even sterilize the sows. Pig castration is mainly based on the following considerations:
First of all, save the cost of breeding, the castrated pigs generally grow fast, the feed conversion rate is high, the feeding cost is low, and the slaughter cycle will be shortened by nearly half of the time;
The second is that it is easy to manage, and the castrated piglets are generally more docile, and there will be no special reflection even after sexual maturity. Otherwise, when it comes to estrus, the pigsty will stage battles every day.
In addition, in order to improve the meat quality, there is no peculiar smell secreted by sex hormones in the castrated pigs, and the meat will be much more delicious. When the boar is not castrated and raised to the slaughter weight, there will be a strong body odor, which is quite sour, and Tian Fei believes that no consumer will accept this taste. Even after someone has touched a boar, they will be denied boarding the bus. The purchase price of uncastrated boars in slaughterhouses is also quite low, about one-third to one-half of the normal purchase price.
In short, the main reason for castration of boars is the price of sale, and the price of non-castrated boars is very low, so they should be castrated.
……
In fact, it is best to do boar castration surgery before 40 catties, so that the piglets have little strength, easy to control, and the wound recovery will be relatively fast. However, these pigs came from other places, and at first they were afraid of not adapting to the water and soil, and they were worried that they would grow slowly after castration, so until now, they have adapted to the environment of Shuanghe Village.
Now the biggest of these are fifty pounds, and one person must not be able to control it. Tian Fei planned to call Sun Yonglin and Tian's father to help.
At present, the main method of castration is still surgery, and there are castration vaccines for boars on the market, but there are not many applications.
In rural areas, for boar castration, a special veterinarian is usually hired. But Tian Fei didn't plan to do this, he wanted to come by himself, it was just a minor operation. When he was in school, Tian Fei learned to do castration surgery, and he also did many cases during his internship.
……
First of all, the piglets should be fasted. It is best not to eat piglets before surgery. Then Tian Fei, Tian's father, and Sun Yonglin changed their clothes and were ready to start castrating pigs.
Sun Yonglin carried a large board two meters long and half a person high, which was used to separate the boars. Tian Fei brought with him some instruments and medicines needed for the operation, including a scalpel (castration), sterilized needles and threads to suture the wound, disinfectants such as alcohol and iodine, hemostatic drugs, sulfonamides, and so on.
"Xiaofei, are you sure you're here for castration? Why don't we go find the village veterinarian?" asked Father Tian uneasily.
"Dad, don't worry, I had this operation many times when I was in school, and there were no technical difficulties. It's okay to start quickly and accurately. Tian Fei persuaded him.
"Lao Tian, I also think it's better for Xiaofei to come, we have so many pigs, there will be more in the future, you can't invite someone every time. I can also learn then," Sun Yonglin said.
"Old Sun, you really should study. It's very simple, learn to give you a salary increase when the time comes. Tian Fei thinks it's good.
As they spoke, the three of them stepped into the pigsty.
……
Tian Fei first placed all kinds of potions and equipment on the windowsill of the pigsty, and then placed the large wooden plank on its side in one corner, together with the two fences of the pigsty, to form a closed triangular area. Then open one side slightly.
Tian's father held the plank, and Tian Fei and Sun Yonglin drove the pig into the triangle together. Perhaps knowing that they are going to be "eunuchs", the piglets are reluctant to drill into the triangle area. Began to run around in the pigsty.
"Don't run away, no one is indispensable. Who told you to reincarnate that the technique is not good, but remember, don't be a boar at all. Tian Fei said cool words to the piglets.
In the end, the little piglets still did not escape the drive of Tian Fei's "big demon king", and obediently walked into the inner triangle area, waiting for the final "knife".
Wait until the little pigs have entered the triangle area, and then Tian's father and Sun Yonglin block a corner and fix the plank.
"Old Sun, you grab one head and come out first, and lift the hind legs", Tian Fei ordered.
When Sun Yonglin grabbed the hind legs and lifted the little pig out, Tian Fei said to Tian's father again: "Dad, you grabbed the two front legs of the little pig, right." Then step over from the pig's head, hold the piglet's head between your feet, and hold it in place, so as not to let the pig move. ”
In fact, people with good skills can perform castration surgery on the pig alone, but Tian Fei doesn't have this technology, so Yin asked two people to help fix it.
Then Tian Fei instructed Sun Yonglin to straighten the piglet's hind legs. Through these few actions, the piggy's ** is clearly prominent, and even the outline can be seen at a glance.
Tian Fei first washed the surface and surrounding skin of the pig ** with soapy water prepared in advance, and then smeared it with 70% alcohol cotton wool for disinfection.
The following is the most important step, Tian Fei disinfected his hands with the same alcohol, and then took out the soaked "big murder weapon" - a castration knife from the tray containing alcohol. This is a very small scalpel, the handle is about ten centimeters long, suitable for one-handed holding, the blade is only three or four centimeters, less than a centimeter wide, it looks sharp, flashing knife.
Tian Fei fixed ** with his left index finger and thumb, and then held the knife at 90 degrees with his right hand. Then pierce vertically on the skin, puncture the flesh membrane of the skin and the total vaginalis, and then cut along the parallel gap about two centimeters long. After putting down the scalpel with the right hand, the thumb and index finger pinched**spermatic cord and vas deferens, the remaining three fingers and palms pinched**, after the left thumb and index finger tore **mesangium, ripped off**ligaments, and pushed the common vaginal membrane and ligaments into **, and the left hand squeezed **skin at the same time to fully expose** and the spermatic cord.
After that, it's time to take off the testicles. Tian Fei held the hemostat again, clamping and fixing the proximal end of the severed end of the spermatic cord that was about to be removed. Insert the index finger of the right hand into the spermatic cord and the vas deferens and rotate it clockwise until the twist is broken. Then fix the wound by hand, and then quickly suture the wound with a sterile needle and thread, usually a stitch in the middle of the area.
After the wound is sutured, a little sulfonamide powder, or cephalosporin powder, is also applied to the wound to prevent infection. If the surgery is done well and there are no problems, it will be fine in two or three days.
Finally, gently massage the lower abdomen of the piglet with the palm of your hand a few times, and then gently put the piglet's limbs on the ground. The castration of the piglets is considered complete.
"Xiaofei, you really have a hand. Sun Yonglin praised.
"We've only finished making one, but we have more than 100 boars to castrate, and the task is very heavy. Old Sun, but you have to work overtime," Tian Fei said to Sun Yonglin.
"No problem, I said I want to learn from you. ”
