For a primitive livestock breeding system, intensive breeding plants similar to those of later generations were absolutely unnecessary. There are no antibiotics and vaccines, gather the two senior brothers together, and then wait for the collective braids.

Therefore, the breeding system of the crossing crowd was scattered at the beginning.

In the vast Tainan Plain, Huo Xiong has set up many breeding sites. These small bases are rudimentary, with a small number of employees and livestock. Generally speaking, a middle-aged and elderly couple is the standard, and a farm with four employees like Qiqiao can already be regarded as a large household.

Rudimentary is a must: every once in a while, the farm site needs to be relocated, and the old enclosures are usually demolished or burned down.

In order to avoid cross-infection as much as possible, the breed of livestock in the breeding site is also single: pigs, sheep, chickens and ducks are not allowed to be mixed. On this basis, Huo Xiong defined the range of livestock movements, drinking water, rivers and sources of fodder for each of the bases.

It's a simple co-ordination strategy: if something goes wrong at a location, managers can quickly identify the source of the disease by cross-cross-checking.

......

Today is no exception. After Huo Xiong came to Qiqiao, through the examination of records and the autopsy, he already had a number of this sudden swine fever in his heart.

Swine fever is not the flu, and this virus cannot be spread in the air. In other words, swine fever can only be transmitted through direct contact or an intermediate host.

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

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

Most of the various livestock pathogens that were circulating in the world in later generations were involved in swill. Europeans fed vegetarian cattle with leftover meat and oil from the kitchen, and then they developed mad cow disease.

After the ordinary swill is transported between pig farms, swine fever begins to spread. By the 21st century, the European Union had issued a decree prohibiting the feeding of swill to livestock. The rabbit country is too thin to prohibit swill feeding overnight, so African swine fever, which is similar to the classic swine fever, can become popular and bloom everywhere.

The 17th-century Crossing Kingdom did not have the ability to ban swill at the moment.

The rice, potatoes and sweet potatoes produced in the farmland that is being frantically reclaimed in Tainan are used to ensure national food security...... It is an overriding political task to feed the exponentially increasing number of citizens under the command of the people.

On this basis, corn and oats from small fodder fields are fed to "high-end livestock": cattle and horses.

Therefore, a "low-end livestock" like the second senior brother can only be done with swill + pigweed at the moment.

......

After examining the swill and feed, Huo Xiong dissected the skin of several dead pigs and found that their hygiene was well maintained, and there were no ticks, the intermediate host of swine fever, on their skin.

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

Every day, I go to drink the so-called "natural mountain spring water", and finally the brain-dead person whose internal organs are covered with parasites under X-rays and don't talk about him.

In terms of domestic animals alone, "natural stocking" is also the dirtiest: domestic animals rummage in the grass to eat, and will eat all kinds of wild animal feces, eggs, and hair tissues into their mouths. In addition, ticks and parasites that transmit various plagues, encephalitis, bacteria, and blood diseases, as well as mosquitoes and flies, which are the source of viruses, are always waiting in the "natural environment".

When they return from the wild at night, they don't know how many germs and parasites they are infected with inside and outside their bodies.

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

The last item Huo Xiong checked was infectious agents such as straw mats.

The result was the same as he had predicted: the pigs had not been transported across regions for nearly two months, so they had not been exposed to intermediate infectious agents such as straw mats in the vicinity.

Well, after ruling out all the causes, now the source of the swine fever is about to come out - Huo Xiong once again gathered the four pig farm workers and began to interrogate them in detail.

It didn't take long for the truth to come out: the youngest employee muttered that his pigs seemed to have been "ridden" by a boar while grazing a few days ago.

Huo Xiong rolled his eyes and showed 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 raged around the world in later generations, can be traced back to the wild porcupines in Kenya in 1921.

"How do you memorize the regulations? Why didn't you report it if you were ridden by a wild boar!? Huo Xiong, who hated iron but not steel, was furious this time, and beat several idiots from the pig farm with punches and kicks......

After the beating, Huo Xiong gasped and glared fiercely at Yamane's wife, who was the only one who had not been beaten: "Hurry up and send it to the canteen, what are you waiting for?" ”

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

The warm Tainan Plain, even in December, even during the Xiaoice period, the temperature does not fall below 15 degrees. So the dead pig had to be sent to the canteen as soon as possible, just in time for dinner.

Seeing a few swineherds disappear in a hurry, Huo Xiong couldn't help but sigh deeply: the overall cultural level of animal husbandry practitioners is too low, which is the most fundamental reason for the frequent occurrence of all kinds of accidents.

Many illiterate farmers stumble over the regulations, and the loose habits of the agrarian society make them lack due respect for the regulations.

"It seems that it can't be appeased." Huo Xiong thought fiercely: "To run an intensive vocational training class, everyone will pass the test, be eliminated by force, and those who are not qualified will rush to open up the wasteland!" ”

After deciding on the next reform plan, Huo Xiong came to his beloved Harley, took out his mobile phone to look, and found that the signal was still two bars, so he called up the phone number of the Chihkan District Government and called.

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

After the two sides said a few words on the phone, the district government hung up the phone. Huo Xiong, on the other hand, stepped on the motorcycle and rushed all the way to the Seven Bridges Canteen.

There are a total of three canteens in the family area on this side of the Seven Bridges. Huo Xiong was speeding along the way, and before the dead pigs arrived, he parked his motorcycle in front of the smallest canteen.

Once inside, he went straight to the small private room, which had a private room for the traveler in each cafeteria. After sitting down to smoke half a cigarette and drink a beer, a chubby man in his 30s in a casual suit opened the curtain and walked in.

This person's name is Shao Qiang, a native of Shaanxi, who was a small clerk in charge of writing manuscripts before the crossing, and is now the deputy head of Chikan.

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

Shao Qiang nodded with a smile, then took out a piece of Huo Xiong's Furong King on the table and nodded: "Now the food problem is a high-voltage line, and my side is almost a rumor, no, I will get it as soon as you call me." ”

Speaking of this, Shao Qiang spit out a puff of blue smoke: "What, I heard that there is swine fever again?" ”

"yes." Huo Xiong sighed: "I was infected by a wild boar, and four of them died in one go, you can eat braised pork later." ”

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

"Cut ......" Huo Xiong had a disdainful expression: "Then have you eaten braised pork in the vegetable market before crossing over?" ”

"I eat this a lot, what's wrong?" Shao Qiang was puzzled.

"So where do you think all those red braised pork and braised chickens came from?"

Seeing Shao Qiang's face gradually reacting, Huo Xiong stabbed him in the heart again: "You don't think that dead pigs and dead chickens are buried, right?" ”

"Isn't it all buried on TV? Bury tens of thousands of heads in one go!? Shao Qiang will be shocked and angry.

"Hahaha." Huo Xiong laughed: "There are more than 40,000 towns and villages in the country, do you know how many chickens, ducks, and pigs are needed to die of disease every day?" ”

"It's all buried as you say, how can those dealers who walk around the village and alleys and have dead chickens hanging on their bicycles still mess up? How can those small meat factories that collect plague pigs to make ham sausages survive? ”

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

"A braised chicken outside the train station is only sixteen, if you don't collect the plague chicken, the boss won't accompany you to death?" In fact...... When Huo Xiong said this, he laughed evilly: "It's a little better in winter, but in summer, many dead chickens turn green when they get out of the pot." ”

"Shut up, you coward!" Shao Qiang was in a hurry, and the words of his hometown came out.

"Hehe, okay, don't worry too much." Huo Xiong changed his conversation at this time and began to comfort Shao Qiang: "The swine fever virus can only survive for 5 minutes at 60oC, in fact, if you look at biology alone, no virus can survive at 100oC for 5 minutes. ”

"So the braised pork is safe, brother, I will eat it with confidence, I will accompany you to eat."

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

"All right, venison is venison, but you'll have to hurry up what I just said."

"I know, I'll have a meeting tonight, and I'll set it up tomorrow."

......

Huo Xiong's meal of venison was not for nothing.

Two days later, 50 hunting teams mobilized by the Chihkan district government began a dragnet search on the Tainan Plain.

The operation was codenamed "Jungler 1849". The purpose of the operation was to clean up wild boars, weasels and voles from the Tainan Plain, and take them out to burn the wasteland.

In this way, the wild second senior brothers fell into bad luck. Within a few days, the wild boar's range was pushed back to the central mountains, and even a large number of weasels and voles on the plains were raided...... It's still terrifying for humans to be ruthless.
