"Hurry up and transfer these heads to the backup point."

"Yes! Sir."

……

Swine fever, also known as "hog cholera", is an acute, highly contagious virus that usually spreads among pigs and has no direct harm to humans.

In later generations, the vaccine immunity period against classical swine fever can reach more than one year, and it is recognized as an attenuated vaccine with good safety, superior immunogenicity, and genetic stability.

However, the time-traveling crowd does not have such a thing.

Not only is there no vaccine, but all kinds of commonly used antibiotics and medicines in veterinary medicine are not available in Transit. A force that is trying to climb the sulfonamide technology tree is still a long way from antibiotics and vaccines.

There is no way, it has been less than two years since the crossing forces came to this plane, and there is no time to build these branch technologies.

Therefore, Huo Xiong, who is the leader of the animal husbandry industry, must find the source of infection today, otherwise, it will be a bad thing if there is a large area of ​​swine fever.

So he picked up the knife and began to carefully dissect the dead pig on the ground for the second time.

Chapter 312

For a primitive livestock breeding system, an intensive breeding factory similar to that of later generations is absolutely unacceptable.Without antibiotics and vaccines, if you gather the two brothers together, then wait for the group to lose their braids.

Therefore, the breeding system of Chuanzhong was scattered from the beginning.

On the vast Tainan Plain, Huo Xiong has set up many breeding sites.These small strongholds are rudimentary, with few employees and few livestock.Generally speaking, a middle-aged and elderly couple is the standard match, and a farm like Qiqiao with four employees can already be considered a big household.

Simple is necessary: ​​every once in a while, the breeding site needs to be relocated, and the original pens are usually demolished or burned down.

In order to avoid cross-infection as much as possible, the breed of livestock at the breeding site is also single: pigs, sheep, chickens and ducks cannot be mixed.On this basis, Huo Xiong stipulated the range of activities of livestock, drinking water rivers and sources of feed for each stronghold.

This is a simple overall defense plan: Once a problem occurs in a certain base, the manager can quickly determine the source of the disease through cross-comparison.

……

Today is no exception.After Huo Xiong came to Seven Bridges, he already knew about the sudden swine fever by examining the records and dissecting the corpse.

Swine fever is not the flu, and the virus cannot spread through the air.In other words, swine fever must be transmitted through direct contact or intermediate hosts.

Considering that the other pigs that were fed the same batch of feed were still alive, the first thing Huo Xiong eliminated was swill infection.

For livestock, swill is the main channel for the transmission of germs.The swine fever virus can be latent for about 20 days at room temperature, and one of the main transmission channels of this virus is kitchen waste.

Most of the various livestock pathogens that are popular in the world in later generations have swill to participate.Europeans used leftover meat and oil from the kitchen as feed to vegetarian cattle, and then there was mad cow disease.

After ordinary swill is transported between pig farms, swine fever begins to spread.In the 21st century, the European Union has enacted a ban on feeding swill to livestock.However, due to the weak foundation of Rabbit Country, there is no way to ban swill feeding overnight, so African swine fever, which is similar to classic swine fever, can become popular and bloom everywhere.

In the 17th century, the country of Traveling through China did not have the ability to ban swill.

The farmland that is being crazily reclaimed in Tainan, the rice, potatoes and sweet potatoes produced therein, the primary task is to ensure national food security... The need to feed the geometrically increasing number of citizens under his command is an overriding political task .

On this basis, the corn and oats produced in a small number of fodder fields will be fed to "high-end livestock": cattle and horses.

So "low-end animals" like the second senior brother can only be handled with swill + pigweed right now.

……

After checking the swill and feed, Huo Xiong dissected the skins of several dead pigs and found that they were in good hygiene and there were no ticks, the intermediate hosts of swine fever, on the skins.

Those people in later generations tirelessly pursue the so-called "natural stocking", and "pure ecology" is actually funny.

Not to mention the brain-dead person who drinks the so-called "natural mountain spring water" every day, and finally finds that his internal organs are full of parasites under X-rays.

From the perspective of livestock alone, "natural stocking" is also the dirtiest: livestock rummages in the grass to eat, and will eat the feces, eggs, and hair tissues of various wild animals into their mouths.In addition, tick parasites that transmit various plagues, encephalitis, bacteria, and blood diseases, as well as mosquitoes and flies that are the source of viruses, are also waiting in the "natural environment" at any time.

The so-called pastured livestock, when they return from the wild at night, they are infected with many germs and parasites inside and outside their bodies.

The only pork that can meet the standard of "clean" in human history is precisely the so-called "injection feed pig" that is despised by people in formal farms-at least this kind of pork will not have a piece of white pork in the fat after it is cut Tapeworm eggs.

The last item that Huo Xiong checked was infectious materials such as straw bedding.

The result was as he predicted: these pigs had not been transported across regions in the past two months, so they were not exposed to intermediate infectious agents such as grass bedding.

Well, after ruling out all the reasons, the source of the swine fever is now coming out—Huo Xiong called the four pig farm workers together again, and began to question them in detail.

It didn't take long for the truth to come out: the youngest employee said hesitantly that a few days ago, his pigs seemed to have been "ridden" by wild boars while they were grazing.

Huo Xiong rolled his eyes while showing an expression of "I knew it would be like this".

… Wild boars are an important source of plague transmission.In fact, the earliest source of African swine fever, which has ravaged the world in later generations, can be traced back to the wild porcupines in Kenya in 1921.

"How did you memorize the regulations? Why didn't you report it when you were ridden by a wild boar!?" Huo Xiong, who hated iron and steel, was furious this time.

After the beating, Huo Xiong stared fiercely at the only wife of Yamane who was not beaten: "Hurry up and send it to the cafeteria, what are you waiting for?"

So a few disappearing goods came out again, hurriedly carried the dead pigs onto the cart, and rushed all the way to the canteen in the Qiqiao family area.

In the warm Tainan Plain, even in December, even in the Little Ice Age, the temperature never dropped below 12 degrees.So the dead pig had to be sent to the cafeteria as soon as possible, just in time for dinner.

Huo Xiong couldn't help sighing deeply as he watched the swineherds leave in a hurry: the overall education level of the animal husbandry practitioners is too low, which is the most fundamental reason for the frequent occurrence of various accidents.

Many illiterate farmers stumble across the regulations, and the loose living habits of the agricultural society make them lack due respect for various regulations.

"It seems that we can't tolerate it anymore." Huo Xiong thought fiercely: "We will set up an intensive vocational training class, everyone will pass the test, and we will be eliminated, and those who fail will go to open up wasteland!"

After thinking about the next reform plan, Huo Xiong came to his beloved Harley, took out his mobile phone to check, and found that there were still two signals, so he called the phone number of the Chikan District Government and called.

The district government took Huo Xiong's call very seriously - they took all calls about food very seriously.

After the two parties exchanged a few words on the phone, the district government hung up the phone.And Huo Xiong got on the motorcycle and rushed all the way to the Qiqiao canteen.

There are three canteens in the family area on the Qiqiao side.Huo Xiong drove at lightning speed all the way, before the dead pigs arrived, he parked his motorcycle in front of the smallest canteen.

After entering the door, he went straight to the small private room—every cafeteria has a private room exclusively for traversers.After sitting down to smoke half a cigarette and drinking a glass of beer, a chubby man in his thirties who was wearing a casual suit opened the curtain and walked in.

This person is Shao Qiang, from Shaanxi. Before crossing, he was a small staff member in charge of writing manuscripts, and now he is the deputy district chief of Chikan.

Seeing Shao Qiang enter the door, Huo Xiong quickly poured him a glass of beer: "District Chief Shao is not slow in coming, he is a model civil servant!"

Shao Qiang smiled and nodded, then took out a Furong Wang that Huo Xiong put on the table and lit it: "Now the food problem is a high-voltage line, and there is almost a panic on my side. No, I will get it as soon as you call."

Speaking of this, Shao Qiang exhaled a mouthful of blue smoke: "Why, I heard there is swine fever again?"

"Yes." Huo Xiong sighed: "Infected by wild boars, four of them died in one breath, and you will be able to eat braised pork later."

"I don't eat plague pork." When Shao Qiang heard this, a disgusted expression appeared on his chubby face.

"Cut..." Huo Xiong had a contemptuous expression on his face: "Then, have you eaten the stewed pork in the vegetable market before crossing?"

"I eat this often, what's the matter?" Shao Qiang was puzzled.

"Then where do you think those bright red meat and chicken come from?"

Seeing Shao Qiang's face gradually come to his senses, Huo Xiong stabbed him in the heart again: "You don't think all the dead pigs and chickens are buried, do you?"

"Isn't it all buried on TV? Tens of thousands of heads buried in one go!?" Shao Qiang was shocked and angry.

"Hahaha." Huo Xiong laughed loudly: "There are more than 4 villages and towns across the country. Do you know how many chickens, ducks, and pigs are needed to die of illness every day?"

"They were all buried as you said. How can those dealers who walk around the villages and have dead chickens on their bicycles hang around? How can those small meat factories that collect plague pigs to make ham sausages survive?"

"I'll go, I haven't eaten less emotionally dead chicken?"

"A stewed chicken outside the train station is only sixteen. If you don't accept the plague chicken, the boss won't accompany you to death?" In fact... Huo Xiong smirked when he said this: "It's better in winter, but in summer, it's a lot." The dead chickens turn green when they go into the pot."

"Shut up, you coward!" Shao Qiang panicked, and all the words from his hometown came out.

"Hehe, well, don't worry too much." Huo Xiong changed the subject at this time and began to comfort Shao Qiang: "The swine fever virus can only survive for 60 minutes at 5°C. Putting it in perspective, no virus can survive more than 100 minutes at 5°C."

"So braised pork is safe, brother, you can eat it with confidence later, I will eat it with you."

"I don't want to eat pork now, so I'll have some venison."

"Well, venison is venison, but you have to hurry up on what I just said."

"Understood, the meeting will be held tonight, and the arrangements will be made tomorrow."

……

Huo Xiong didn't ask for this meal of venison for nothing.

Two days later, 50 hunting teams mobilized by the Chikan District Government began to search and hunt with nets on the Tainan Plain.

The code name for this operation was "Jungle 1849".The purpose of the operation is to clean up the wild boars, weasels and voles on the Tainan Plain, and take them away for burning.

In this way, the wild second senior brothers were in bad luck.In a few days, the range of activities of the wild boars was pushed back to the central mountain range, and even a large number of weasels and voles on the plain were raided... It is still very scary for humans to be cruel.

Chapter 313 Bamboo Rat

After Huo Xiong dealt with the pig farm accident, he came to his office in the animal husbandry head office the next day, and then called his staff for a meeting, made plans, and wrote reports... Now he urgently needs to conduct a large-scale rotation training in the entire animal husbandry system in order to improve Professionalism of employees.

However, blessings and misfortunes never come singly. Just after he finished making plans, there was another bad news: the bred bamboo rats ran away...

The frustrated Comrade Huo Xiong had no choice but to ride his Harley motorcycle again and head straight for the bamboo rat breeding factory.

……

In the mature breeding system of later generations, crops need to undergo secondary transformation to reflect their value.

The farmers first grow the corn, then make the corn into feed, and finally the corn will be added value... They are transformed into steak and bacon, and they have completed the last link of the farming chain.

The above-mentioned breeding mode encountered resistance in Transit Zhong: all the crops were used to fill the stomachs of human beings, and it was very difficult to expand the scale of animal husbandry, so it could only develop slowly.

Under such circumstances, bamboo rats, which feed on bamboo, miscanthus, and plant stalks, have come into the sight of the Headquarters of Animal Husbandry—any comrade who does not compete with cattle and horses for feed is a good comrade and worth raising.

Because the food is a variety of low-energy crude fibers, the bamboo rat looks like a mammal, but its meat has a lot of crude protein and is more inclined to "white meat". In later generations, it was sold as a healthy food, 100 per catty, very expensive.

But there are not so many flowery intestines in the raising of bamboo rats in the time-traveling crowd-it is purely for eating meat.

Bamboo rats can directly transform bamboo into flesh, which is very precious in Tainan, where there are many bamboo forests.In addition, the fur of the bamboo rat is also good, and the wealthy people in the Yangtze River Valley are willing to buy a rat fur cloak to wear in the cold and wet winter.

Similar to other breeding sites, bamboo rat farms are small and scattered.

Huo Xiong drove eastward from the Chikan District Government on a motorcycle. After walking the asphalt road, he took the gravel road and finally the dirt road. After nearly 20 kilometers, he came to the bamboo rat breeding base located in a hilly area.

This place is not far from the central mountain range, and there are continuous bamboo forests and streams everywhere, which is very suitable for raising bamboo rats.Several large red brick houses were scattered on the nearby hills. After hearing the roar of motorcycles, the people inside greeted them.

"What's going on?" Huo Xiong got out of the car, saw two people coming towards him, and asked a young man who was sixteen or seventeen.

The young man was named "Six Sons" and he was a refugee from the south of the Yangtze River.The young man works hard, has a positive attitude, and works hard to read and count. He is a talent that Huo Xiong is more optimistic about.

"Run away a nest!" The six sons were full of panic.

"Go and have a look." Huo Xiong stepped into the enclosure.

The area of ​​the red brick house is about 100 square meters, and inside are small squares built with thin stone slabs.Since bamboo rats live underground all year round, the tops of these half-person-high small squares are covered with grass curtains for shading.

Raising a straw curtain at will and looking down, what caught Huo Xiong's eyes were five or six chubby, chubby, sub-adult bamboo rats with the most beautiful appearance in the rodent world and about the same size.

The main species of bamboo rat raised by farmers in later generations is Silver Star Bamboo Rat.After many generations of artificial breeding, this breed has the characteristics of fast growth and large size, which is very suitable for artificial breeding.

The bamboo rat industry of Chuanzhong was also developed from 50 "imported" silver star seedlings.

The difference from later generations is that there are not only silver star bamboo rats here, but also Chinese bamboo rats and red-cheeked bamboo rats collected from the Ming Dynasty in several pens, including the local bamboo rat species in Tainan. nurture.

You must know that in later generations, the Chinese bamboo rat has become a protected animal, and it is not allowed to be sold.

……

After casually looking around, Huo Xiong, led by his six sons, came to the escaped nest of bamboo rats.

The straw curtain on the top of the grid had been lifted. After Huo Xiong came over, he first probed in to have a look, and then reached out to touch the bottom of the stone slab.

"The cracks left below have been gnawed into holes, can you not run away?" Huo Xiong patted the ashes on his hands, then turned his head and asked, "Didn't you notice that the bamboo rat is gnawing on the stone slab?"

At this moment, Liu Zi was full of frustration: "A few rats blocked the cracks in the stone with their stomachs, so they didn't notice."

"Oh..." Huo Xiong shook his head: "Take me to the feed room."

Because bamboo rats have a habit: they will automatically clean up their feces out of the nest, so there is a gap under each block.

Now that the hole at the bottom was gnawed out by the fugitive, Huo Xiong immediately thought of the problem of feed: maybe he was hungry?

After the three came to the feed room next door, Huo Xiong first checked the various feeds in the room, and then stretched out his hand: "Bring me the feeding record."

A papyrus notebook was handed over to him.

The sources of feed for bamboo rats are very rich: soft and hard bamboo, bamboo roots, bamboo shoots, corn stalks, sweet potatoes, including elephant grass and emperor bamboo grass, melon rind, and sorghum stalks brought by the later generations of the crossing crowd, all of which can become bamboo rats. feed.

Except that the mother mouse needs to be fed a little rice bran to increase nutrition during the lactation period, the bamboo rats live on the above-mentioned crude fiber feed for the rest of the time.

When Huo Xiong opened the record book, what he saw was the recent feeding record in the enclosure.

Liu Zi is a very diligent worker. He recorded the daily feed consumption and types in detail in the notebook, and he even marked some words that he couldn't write with graphics, which made Huo Xiong nod his head: "Liu Zi, I'll give you back later." You enroll in a committee training class and learn some cultural knowledge, which is what you lack now."
