The crowd came to the piglet room again, where there were countless sows and piglets. And several of the sows are in the process of giving birth, and a few piglets have come out of the ground, and they are still a little wet. One of the sows had already given birth to five piglets, and her belly was still swollen and moaning in pain.

The midwifery machine did not relax, and immediately replenished an injection for the sow, and the sow's pain eased. The other robotic arm strengthens the peristalsis by pushing the sow's belly, allowing the piglets to be born without a hitch.

"The production process of the sow is also taken care of by the robotic arm, which helps the mother sow to give birth to all the piglets smoothly."

The rows of piglets in front of them are sucking their mother's milk, and the sows are held to the ground by the binding.

"That's how piglets are fed, each sow gives birth to about five to fifteen piglets at a time, but with our genetic modifications, we can produce more than fifteen piglets at a time. Feed in two batches. With that, the feeding time of the first batch was over, and the piglets were forcibly isolated by the machine and rushed to their cages.

"The burden on the sow is so great." Ben Tonggen complained again.

Next, everyone came to the assembly line of piglets, and one piglet after another was pushed onto the conveyor belt in turn. I saw that each headless piglet was separated to another conveyor belt.

"This is the assembly line after the piglets are weaned, and one leads to the slaughter line, which is directly made into young pork products. One leads to a new feed growing room. Among them, the boars are castrated. ”

"Life is simple, death is random, may the paradise of pigs have no farms, oh no, there are no humans who eat them." Ben Tonggen whispered about this random slaughter line, Lu Li rolled his eyes and ignored it.

"What is death? Mr. Otani. "Teacher Zhang doesn't know what castration is.

"Castration is the castration of boars, improving feed utilization, reducing activity and fighting between boars. Look, that's castration. Otani pointed to the machine in front of him.

The juvenile boars were grabbed and fixed by basket-shaped robotic arms and injected with injections.

"Injections of disinfectant and anti-epidemic injections to prevent infection and infection. By the way, there are also some anesthetics to reduce the pain sensation of the piglets. Kei Ohtani said.

The assembly line came here, a robotic arm skillfully operated the piglets, disinfection, cutting, and hemostasis were completed in just ten seconds, and the piglets only screamed for a short time, and then separated from their own guys forever.

The children thoroughly understood what this program was doing, and some of the children covered their eyes with some fear.

"Uncle, this is also terrible, why do you want to cut off Piggy's younger brother?" A child asked.

"Because pigs that are not castrated are too active and difficult to manage. We can only castrate them in advance, so that the piglets can grow faster. It's all for their good. Otani patiently explained again.

"Hey, it's all for your good, it's the most disgusting thing I've ever said in my life, it's all about improving productivity and for the sake of collectivization, depriving them of everything." Ben Tonggen whispered again.

The next space is the space for raising pigs that are close to the slaughter period, and there are more than a dozen pigs living together in each penny, and there are white flowers as far as the eye can see.

"The pig feed in our farm is the highest standard pig feed, made from wheat, barley and minerals, which is nutritionally balanced and can be eaten even by humans." Let's talk about it, Kei Otani grabbed a handful of it from the feed trough, and the feed was yellow and looked like it was really edible.

"Which of you would like to taste it?" Kei Otani asked, stretching out his hand. Of course, the children did not dare to try pig feed, so they took half a step back and shook their heads.

Otani Jing was a little disappointed that he tasted a few of them, and Lu Li also curiously stepped forward and took a few and stuffed them into his mouth.

The taste is not bad, the fine soft particles, the mouth does not need to be chewed and sipped for a while, and the taste has some sweetness unique to grains.

Lu Li even wanted to buy a few bags and go back to make milk to drink. But he immediately stopped his useless thoughts.

"Yes, it's delicious." Lu Li praised.

"yes, I didn't lie to everyone." Otani nodded in satisfaction.

Several children were also a little nervous in the face of Lu Li's appreciation, but they were stopped by Teacher Zhang.

Next, the group came to the slaughtering area, where the pigs were carefully raised for five months. The bodies are very large, together in an open space, playing light music.

It was the first time for the pigs to be in such an open space, and their big noses were very cute, but they didn't know what they were going to experience next.

"After five months, the pigs reached the right weight and were ready to be slaughtered for meat processing." One by one, the adult pigs were herded into a closed glass room.

"Now it's the slaughtering process, and unlike the physical slaughtering process in the past, it's all CO2 slaughtering, so that the pigs die painlessly."

Looking at the pigs in the glass room, they fell to the ground unconscious one by one, and some soft-hearted children left tears.

"Ah, merciful human beings, who have bestowed upon their food a painless death. Hopefully, the next time they're having lunch, they'll be able to think of these cute pigs, and that shouldn't be the day they should. Ben Tonggen exclaimed dramatically.

Then the crowd came to the cattle factory. Calves are confined to an extremely small pen. There is no room to turn around, and even turning the head can only turn slightly.

"Uncle, why is every calf confined in such a small place?" One child asked.

"Because it restricts the amount of activity of the cattle, the meat that comes out of the slaughter is more tender." Kei Ohtani said.

"From birth to death, I have been confined to this two-foot place, and there is no freedom." Someone added in a whisper.

"Uncle, why do these cows have holes in their backs?"

"In this way, they can better monitor the information in their stomachs and intervene appropriately to make each cow grow healthier and even extend its lifespan, which we call 'wilting cows'."

"Tut, even the stomach can be seen through, there is no freedom, and even privacy is not available."

Lu Li was a little insufficient, if he hadn't been able to beat the guy behind him who was whispering nonsense, he would have turned around and beaten him a long time ago.

"Will they be in pain?" One child asked.

"No, when each cow burrows, we will do general anesthesia, and the cow will sleep and the operation will be over, and the burrowed cow will not feel any discomfort." Otani swore solemnly.

"Hey, how did he know? Is he a cow? Lu Li complained again.

"Now we're in the milk collection room." Everyone came to a huge workshop, standing on a high platform and looking down from above, there were huge discs, and on the discs were dairy cows. Each cow is very conscious, and consciously walks on the turntable without urging, and it is also very calm when collecting milk, as if it is integrated with the milk picking turntable.

"Each cow is plated once a day, the milk is picked once and turned in a circle. One turn, ten minutes. Kei Ohtani introduced the milk harvesting machine.

"Milk collection is also fully automated. From the plate, sterilization, docking collector, milk collection. Even cleans and massages each cow by the way. The central computer knows the condition of each cow well, weight, whether it is pregnant, milk output, food consumption, etc., and customizes the management of each cow according to the collected data. Kei Ohtani said, pointing to the monitor in front of him.

The data for each cow is displayed on the display, and each square represents a cow, identified by numbers. The difference in the background color means that the cow is in the recuperation period, the conception period, the waiting period, and so on.

After visiting the cows and pigs, they came to the chicken farm.

The layout of the chicken farm is about the same as that of the pig farm, with a patch of chickens under the long sidewalk in the middle, but the observant students have already seen that the chickens are clearly different from the chickens in the materials.

"Uncle, why do these chickens have three pairs of wings?" A child asked.

"This is a genetically modified chicken developed by our factory's scientific research team." Kei Otani replied with a proud face.

"I remember hearing a rumor when I was a kid that my mom told me that the chickens in those fried chicken restaurants were chickens with three or four pairs of wings in order to prevent me from eating fried chicken wings all day, which scared me out at the time, and later I found out that it was a rumor. Now that I've seen this kind of chicken, it's real? Teacher Zhang said recallingly.

"It was a rumor at the time, because a few years ago there wasn't the capacity to produce winged chickens. Genetic modification is a very complex project. There are two major challenges in overcoming the multi-winged chicken. ”

Kei Ohtani stretched out two fingers and continued: "One is that it is difficult to be accurate, we all know that although the gene is extremely small, it contains all the information of this creature, if you change a certain point on this gene, especially if you change the number of limbs of the chicken, this major change is very likely to cause a chain reaction and cause mutations in the experimental body." Severe severity can lead to deformity and even death of the subject. So we had to be extremely precise and only change the number of wings of the chickens without affecting the other variables. ”

"Another is the difficulty of scale, earlier scientists can indeed make chickens grow four more pairs of wings, but it is by means of embryonic transfer, which is very complicated and costly, so that large-scale production becomes impossible. Later, there was finally a technological breakthrough, and scientists successfully engineered the stem cells and genomes of broilers, and finally developed multi-winged chickens. ”

"Then can you accept multi-winged chickens? Decades ago, it was rumored that the multi-winged chicken was designed to intimidate others. Teacher Zhang asked.

"Nowadays, people are much more receptive to high-tech, and our genetically modified chickens not only have two more pairs of wings, but also taste better and more nutritious. Everyone naturally likes our multi-winged chickens, and our factory even uses unique multi-winged chickens as advertisements. Kei Ohtani took out a box of finished chickens, and the promotional pattern on them was impressively printed with multi-winged chickens.

A chicken with three pairs of wings soars above the blue sky, with the slogan next to it, "One more pair of wings gives a little more hope." ”
