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 and 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. The others all popped up when they ate beef. 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. 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. As a result, 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 would not be exchanged 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."

Generally speaking, the ancient livestock breeding 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 roasted bamboo rats.

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, there is a reason why he and Wang Goode still drank coffee. Next, they still have important work to do and cannot 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 traveling through the crowd to collect these female buffaloes is very simple. It is not for them 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, 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.
