The six sons looked excited: "The little one is gone, who will take care of the bamboo rat?"

"No one can take care of you better than you!" Huo Xiong said later, but at that moment, his face changed instantly, and he took the record book and knocked on the head of the six sons.

"Oh, master, spare me!" The six sons were beaten and ran around the room.

After Huo Xiong was out of breath, he grabbed Liu Zi's ear and began to interrogate: "Tell me, why has the amount of hard bamboo fed decreased?"

"Feed more fine grains to make the mice fat faster!" Liu Zi plausibly said.

Huo Xiong was so angry that he rolled his eyes again: "Did you tell me during the training that the bamboo rat's big dies are growing every day?"

"I've said it... the little one knows!"

"You know what a fart, if you don't feed them hard bamboo to grind their teeth, won't they just bite the slate?"

"So it is!" The six sons suddenly realized.

"Each bamboo rat must be fed with a piece of hard bamboo every day, and the rest of the fine ingredients will be mixed randomly, and random changes to the recipe are not allowed." Huo Xiong tapped the six sons on the head again: "You are doing bad things with good intentions, one of Lao Tzu's Worou just ran away. Alas, I will train you on the first turn around!"

At this time, the six sons smiled and said: "Master, don't be angry, tomorrow I will go to the mountain to catch ten and come back to make amends."

"Fuck you!" Huo Xiong became even angrier now: wild bamboo rats not only spread various diseases, but also have violent personalities and are not easy to reproduce. They need to be scientifically selected and bred for several generations before they can be raised as breed rats.

After sternly criticizing the six children, Huo Xiong ordered the two breeders to quickly check all the gaps in the stone slabs, and replace those whose teeth were ground by bamboo rats.

……

After a lot of tossing, Huo Xiong finally eliminated the problem in the bud without causing any greater losses.

After rejecting the roasted bamboo rat lunch proposed by the six sons, Huo Xiong planned to leave - he had to go to the cattle breeding farm to do important things, so he didn't have the time to roast the bamboo rat.But when it comes to bamboo rats, I still have to take a few with me. A certain traveler at the cattle breeding farm loves to eat this stuff.

So before leaving, Huo Xiong found a bamboo cage and began to pick mice: "This one has been in a fight and has injuries, I took it away...well, this one is limp, it may have suffered from heat stroke, I took it away... This one is thinner, probably suffering from depression, I have to take it away..."

In this way, after Huo Xiong put a few bamboo rats into the cage, the beautiful Harley motorcycle once again took on the job of the delivery guy, roaring away all the way.

……

The bull breeding base is 10 kilometers south of Chikan, close to Kaohsiung.A few months ago, after the army launched the campaign to clean up the countryside, it has "naturalized" all the native tribes north of Kaohsiung Creek. The land they left behind is now planted with various grasses and used as farms.

After Huo Xiong's motorcycle passed the bustling area around Chikan, he ran south for another 10 kilometers. After passing through several alfalfa and elephant grass fields, he saw a farm surrounded by wooden fences from a distance.

Cattle are a kind of livestock with the highest economic value, and they are also a kind of livestock that can have a profound impact on the entire society and the entire human race.

In the future plan of the people, their descendants will definitely not use pork as their staple food anymore - the vast North American Great Plains and Pampas grasslands are used for their descendants to graze and grill Tomahawk steak.

So on this issue, most of the time-traversing people support the attitude: early layout, early harvest.

With this guiding ideology, the big office at the time... the current cabinet also gave the green light on the cattle breeding issue, and Huo Xiong and his team basically met all the requirements for importing materials, and no one was blocked, satirized, insulted, or beaten. All kinds of common situations.

When he came to the gate of the cattle farm, Huo Xiong stopped and said hello to the guard: there are important properties of the empire here, so a security team with guns is specially equipped to patrol.

After entering the cattle farm, you can see the long barn standing on the grass from a distance.

The cowshed is built with red bricks and cement. It is tall and strong, and steel bars are used on the top. There are newly manufactured large glass windows on the walls for ventilation. It can be said that no expense was spared.

Equipment including water pipes and earth-made circulating water coolers are equipped here. Except for the low appearance, it is no worse than the color steel cowsheds of later generations.

"Roasted bamboo rat..." Huo Xiong came to the cowshed, stopped the motorcycle, and yelled loudly.

The next moment, a man in a white coat with curly hair and fair skin came out of the cowshed.

Wang Goode, with a quarter of Mexican blood, is the only professional veterinarian among the 250 crossings.

Chapter 314 Cow Breeding

When Wang Goode was a veterinarian in Mexico, he was called "Goodman" by the locals.

Later, when Cao Chuan "recruited" a veterinarian at the request of Huo Xiong, Wang Goode, who was a veterinarian in this chaotic place in Mexico, came into someone's sight.

Wang Goode, who has a quarter of Mexican...Spanish white blood, basically has no obvious characteristics of white people except that his skin is fairer and his face is a little bigger than others.

After this gentleman crossed over, Huo Xiong's urgent need was solved—it is very difficult to develop the animal husbandry industry a little bit. More than 200 people traveled through the crowd, and Huo Xiong was the only one who had contact with the animal husbandry industry. When the others ate beef, they all popped up. When they said they would change their careers to raise cattle, they all ran away...

Although Huo Xiong is a biology student, his skill points are biased towards theoretical knowledge, making plans, and he is qualified to do research, but he is a bit sloppy in actual operation.

This problem was not resolved until Wang Goode arrived.The two of them cooperate tacitly now, Huo Xiong is in charge of the daily management of the company's business, and Wang Goode is in charge of high-end projects.

……

Today, after hearing Huo Xiong shouting outside the cowshed, Wang Goode, who was inspecting the bulls, came out: "Not bad, they look very energetic, and they should taste good when roasted."

After patting the cage containing the bamboo rats, Wang Goode called the farm helper and ordered him to roast the bamboo rats... the old man will eat them later.

"How is it? Are you in good condition?" Huo Xiong entered the barn and stood in front of the railing of a cow that was feeding a calf, looking at the mother and child in comfort.

Considering the concrete floor, 24-hour duty, alfalfa and elephant grass in the trough, the cows who can have room in this barn are definitely not ordinary cows: these yellow and white flowers are tall and can weigh 800-1200 The kilogram baby is called Simmental cattle, which is a high-end breed of cattle specially "imported" across the country.

Simmental cattle are native to the Swiss Alps. They are not purebred beef cattle, but a breed of both milk and meat.However, Simmental cattle have a high milk yield, and their meat production performance is no worse than that of specialized beef cattle breeds, and their service performance is also very good. It is a large breed of milk, meat and service.

This breed was introduced into China before the Cultural Revolution. At that time, the improvement effect on cattle in various places was very obvious. The production performance of the first generation of hybrids can generally be increased by more than 30%, so it is very popular.

Naturally, it is impossible for these babies brought in from across the country to be used for crossbreeding and drafting—a pair of gas tractors is far more effective in the plains than a herd of cattle.The future food base of the Traveling Kingdom will definitely not be placed in the mountainous Ming Dynasty, and the plains suitable for large-scale mechanization similar to North America are the established locations.

Therefore, the Simmental cattle imported by Huo Xiong are mainly used as beef cattle, followed by dairy cattle, regardless of their use.

In the next 100 years, the only direction that the animal husbandry industry in the country needs to strive for is how to expand the original population of the dozen or so Simmental cattle in front of us.

There are currently eight cows and two bulls in the barn, plus eight cow calves.

When it was first imported, every four pregnant cows could just occupy one box, of course, in a lying position.In the second month after arriving in Dayuan, the cows gave birth one after another... so there were eight more cow calves in the cowshed.

These sixteen cows, big and small, and two majestic breeding bulls are the most valuable assets in Huo Xiong's hands... To be honest, they wouldn't change them for an armored division.

In order to reproduce the population, Huo Xiong and the others also caused a lot of trouble for Cao Chuan: when the calves were in the womb, they passed the B-ultrasound screening, so the eight calves were deliberately selected cows.

In addition, the male line of the calf is the eight out-of-line bulls selected in the old world, not the offspring of the two bulls in front of us.Therefore, after the heifer grows up, it can continue to breed with two bulls without inbreeding traits.

On this basis, through establishing archives, cross-breeding and introducing a small amount of out-of-line bulls in the future, a native population of Simmental cattle will expand healthily.

……

After Wang Goode arranged the matter of roasting bamboo rats outside the door, he heard Huo Xiong's question when he came in, so he replied: "The condition has been good for the past two days, but a small one knocked its leg, it's too dirty."

"Oh, it's still quiet here." Huo Xiong shook his head and sighed, "Four pigs over there died, and a litter of bamboo rats also ran away. I've been getting dizzy these two days."

Wang Goode laughed after hearing this: "It seems that management needs to be strengthened."

"Yes, intensive training is needed." Huo Xiong sighed, "There is a long way to go."

Wang Goode agreed with the latter sentence. He stared at the calf scurrying in the fence in front of him, and said pointedly: "Yes, there is a long way to go."

...In general, the farming of livestock in ancient times is completely opposite to that of later generations.

The ancients did not need livestock with a high lean meat rate, and the ancients did not have industrialized feed to intensively fatten livestock, so these pig breeds and cattle breeds with extremely fast growth rates in later generations did not show any advantages in ancient times.

However, after the re-opening, a large number of domestic native populations began to become extinct, or were on the road to extinction.

The characteristics of these native populations are very uniform: high fat rate and slow growth.

There is no way, after thousands of years of artificial breeding, the livestock with high lean meat rate are all slaughtered, and they have no right to propagate offspring.And the populations that can only graze and free-range have no basic conditions for rapid growth.

What Wang Goode and the others are doing now is no different from those multinational animal husbandry companies in later generations: first expand the population, then put out various fast-growing livestock on the assembly line, and finally drive out the local populations such as native pigs and cattle.

Therefore, the future of these people has a long way to go: to completely change the country's animal husbandry structure, it is necessary to industrialize the planting of feed, industrialize the manufacture of antibiotics, and industrialize the slaughter of livestock...

One generation is roughly not enough.

……

After inspecting the cow and calf, Huo Xiong came to the corral of the two bulls.Grumpy bulls cannot be housed together, they are separated by high feed pens.

Seeing the tall and strong bull with a weight of 1200 kilograms quietly eating corn stalks, Huo Xiong gave a smirk, walked around behind the bull's buttocks, and stretched out his hand to touch the pair of bowl-sized balls. Bundle.

The bull got angry as expected, turned around and pushed it with its horns, shaking the railing with thick thighs.

"You kid, just do it. The idiot who got his butt pierced last time doesn't seem to have taught you a lesson?"

"Haha, I just want to see how energetic our bulls are." Huo Xiong laughed while shaking his hands: "Not bad, a big guy has a big temper!"

…After inspecting the barn, it’s time to eat the roasted bamboo rat.

Bamboo rat meat is a bit similar to fish meat, and it is not greasy at all, so two people can easily handle one each.

"Okay, leave one for me to eat tomorrow." After Wang Goode finished eating, he picked up the coffee pot and poured Huo Xiong a cup while belching.

Huo Xiong didn't drink beer today.Even if the painting style is wrong, he and Wang Goode still drank coffee... There is a reason for this, and they still have important work to do, so they can't drink.

After drinking a cup of coffee and taking a short break, the two of them came to the second row of cowsheds at the rear.

All the buffaloes raised in this group of cowsheds, to be precise, are all female buffaloes.Nearly 200 healthy female buffaloes are kept in the rear row of cowsheds.

In the south of China in the 17th century, the only cattle species that can be collected in the crossing are the Chinese buffalo.These Chinese buffaloes are strong in physique, resistant to ticks, resistant to rough feeding, strong in adaptability, and good in service performance. They are important livestock resources.

However, the purpose of collecting these female buffaloes is very simple. It is not to plow the rice fields, but to use them as an excuse... Yes, these female buffaloes are used for surrogacy.

……

In the second decade of the 21st century, when people travel across the world, the development of science and technology can be described as changing with each passing day; the result of high-speed information is that any technology will quickly spread to human society.

Therefore, in later generations, embryo transfer, a technology that can rapidly expand the population, has become a standard configuration for larger pastures.

Embryo transfer, as the name suggests, is to remove the fertilized eggs from the cow and transplant them into another cow.

This transplantation is not the same as crossbreeding.The offspring produced by crossbreeding animals have both paternal and maternal genes. For example, when Simmental cattle are crossed with yellow cattle, the calves produced are "four different" and have the characteristics of both parents.

After receiving the embryo transfer, the calf is theoretically completely irrelevant to the mother.Because the embryo has been fertilized before it is transferred into the surrogate cow, the characteristics of the calf depend on the two parties who provided the fertilized eggs, and it has nothing to do with the surrogate cow.

In fact, this technology is the ranch version of the well-known test-tube baby technology... Humans "manufactured" the first test-tube baby in 1978; in 2011, a wealthy businessman in Guangzhou used the test-tube baby technology to conceive octuplets... Great, right?

The matter is specific to the crossing crowd. What Huo Xiong and the others are going to do today is to transplant a batch of purebred Simmental embryos into the female buffalo.

In this way, after 280 days, the buffalo mother will give birth to a purebred Simmental calf.

……

When Wang Goode was in Mexico, he would often go to the nearby Meidi ranch to do some embryo transfer business, so he had sufficient technical reserves in this regard.

But Huo Xiong didn't make it. He was quite clear about the steps of embryo transfer, but he had never done it before, so today's surgery is still dominated by Wang Goode.

The first thing the two of them had to do was go to the ranch lab to thaw the embryos.

Embryos to be transferred are stored in refrigerated tanks of liquid nitrogen.These are fresh frozen embryos that Cao Chuan bought from a large ranch in South America this morning. There is a strict time limit for embryo transfer, so the two parties must be connected.

This is where the all-important embryo transfer takes place, because cows in estrus don't wait for anyone.

You know, during the period after Cao Chuan ascended the throne, the import of materials from other industries has all stopped.The entire crossing country is currently in a state of sideways consolidation, and it will not reopen until it has accumulated a certain amount of mobile import capacity.

Chapter 315 Embryo Transfer and Ma Zheng

In theory, it is best for the donor cow and the recipient cow to go into heat on the same day, which can increase the chances of embryo survival.So when the emperor brought the liquid nitrogen tank early this morning, Wang Goode, who had already prepared, selected all the cows in estrus among the buffaloes.

The next step is to defrost.

Wang Goode took Huo Xiong to the laboratory. The two first changed into isolation suits, then they took out the thin tube containing the embryos from the liquid nitrogen, and then immersed the thin tube in warm water at 35°C.

After 20 minutes, the thawed embryos are also diluted several times with 0.3 M sucrose solution...this is done to remove the glycerol in the cells.

The final step is to verify embryo viability.After the two had examined the embryos with a microscope, the preparatory work was completed.

Thanks to the advanced chromosome identification technology of later generations, these selected embryos have a probability of more than 95% to produce cows in the future.Therefore, science and technology are the real reasons behind all the miracles. Wang Goode and the others actually enjoyed the results standing on the shoulders of countless giants.

After preparing the embryos here, the farm workers over there have also pushed the female buffalo into the special barrier.

The parry is a very narrow wooden aisle, and the cow cannot turn around after entering, but can only honestly show the cow's buttocks for surgery.

The previous embryo surgery required an incision in the abdomen of the cow for transplantation.With the continuous improvement of technology over the years, the whole process is now without a knife...instead of a gun.

After everything was ready, Comrade Wang Goode first came behind the cow, then he let out a soft drink, fell down from the horse, aimed at the cow's buttocks, and stabbed a part of his body...into it.

After stabbing, Wang Goode looked up at the sky with a tasteful expression on his face.As the pierced part squirms gently, accompanied by the cow's cry of "Mou Mou", the scene is very exciting.The farm workers surrounded by them had never seen such a beautiful scene before, each of them swallowed dryly, and they were all dumbfounded.

It was too late to say it, but it was so fast, after Wang Goode squirmed a few times, accompanied by a low shout of "the gun is coming", Huo Xiong, who was helping at the side, hurriedly handed over the toilet paper... Wrong, it was a transplant gun.

It was his arm that Wang Goode inserted into the cow's butt just now.

He does this because he first checks which ovary the cow's corpus luteum is on: Cows with hypoplastic corpus luteum cannot be transplanted.

After that, he has to hold the cow's cervix with his hand, and then he has to take over the implantation gun with his other hand, and then poke the tip of the gun into the cow's uterus to inject the embryo.

The entire surgical process must be fast and accurate to avoid damage to the tissue—if you are not careful, you will puncture it.

In one afternoon, the two performed embryo transfer operations on more than 40 cows.

Some of these cows are in estrus, while others have adjusted their estrus through injection of hormones.In short, with the existing conditions of the farm, Wang Goode and the others have done their best.The next step is to wait for the judgment of fate - if more than half of the cows are successfully pregnant, then today is considered a success.
