Section 314 Breeding cattle
When Goode worked as a veterinarian in Mexico, he was known to the locals as "Goodman."
Later, when Cao Chuan "recruited" a veterinarian at Huo Xiong's request, Wang Goode, who worked as a veterinarian in the chaotic land of Mexico, came into someone's sight.
There is a quarter of Mexico...... Wang Goode, who is of white Spanish descent, basically has no obvious characteristics of white people except that his skin is relatively white and his face is a little larger than others.
After this gentleman crossed over, he solved Huo Xiong's urgent need - it was very difficult for animal husbandry to develop little by little. More than 200 people crossed the crowd, and Huo Xiong was the only one who had come into contact with animal husbandry......
Although Huo Xiong is a student of biology, his skills are biased towards theoretical knowledge, and he is qualified to make plans, and he is qualified for research, but he is a little sloppy in practical operation.
This problem was not solved until the arrival of Wang Goode. The two of them now cooperate more tacitly, Huo Xiong is responsible for the daily management of the company's business, and Wang Gude is responsible for high-tech projects.
......
Today, after hearing Huo Xiong shouting outside the cowshed, Wang Gude, who was inspecting the breeding cattle, came out: "Not bad, it looks quite energetic, and it should taste good when roasted." β
After patting the cage containing the bamboo rat, Wang Goode called the farm helper and ordered him to roast the bamboo rat...... He's going to eat it later.
"How's it going, you're not bad, right?" After Huo Xiong entered the barn, he stood in front of the railing of a cow that was breastfeeding her calf, and looked at the mother and son in front of him with satisfaction.
Considering the concrete floors, the 24-hour duty, the alfalfa and elephant grass in the trough, then the room in this barn is certainly not your average cow: these yellow and white, tall and weighing 800-1,200 kilograms of treasures are called Simmental cattle, which are specially "imported" by the high-end cattle breed.
Native to the Swiss Alps, Simmental cattle are not purebred beef cattle, but a dairy breed. However, Simmental cattle have high milk production, and their meat production performance is not worse than that of specialized beef cattle breeds, and their service performance is also very good, and they are large breeds with milk, meat and service.
This breed was introduced to China before the Cultural Revolution, and at that time, the improvement effect on cattle in various places was very obvious, and the production performance of the hybrid generation could generally be increased by more than 30%, so it was very popular.
Naturally, it is impossible for these treasures to be crossbred and used in the crossingsβa gas tractor or two can be far more effective than a herd of cattle on the plains. The future grain base of the crossing country will not be located in the mountainous Ming country, and the plain area suitable for large-scale mechanization such as North America is the established location.
Therefore, the Simmental cattle imported by Huo Xiong and them are mainly beef cattle, followed by dairy cattle, and the service is not considered.
In the next 100 years, the only direction that the animal husbandry industry needs to struggle for is how to expand the native population of the dozen or so Simmental cattle in front of them.
At the moment there are eight cows and two bulls in the barn, with eight heifer calves.
When it was first imported, every four pregnant cows could occupy just one box, of course, in a lying position. In the second month after arriving at the big staff, the cows gave birth one after another...... So there were eight more cow calves in the barn.
Sixteen cows of this size, plus two strong breeding bulls, are the most valuable assets in Huo Xiong's hands...... To tell the truth, I don't change an armored division.
In order to reproduce the population, Huo Xiong and the others also made a lot of trouble for Cao Chuan at the beginning: when the calf was in the mother's womb, it passed the B-ultrasound screening, so the eight calves were all deliberately selected cows.
In addition, the calf's sire is eight foreign bulls selected from the Old World, and is not a descendant of the two bulls in front of him. Therefore, when the heifer grows up, it can continue to breed with two bulls without inbreeding.
On this basis, in the future, through the establishment of archives, cross-breeding and the introduction of a small number of foreign breed bulls, the native population of Simmental cattle will expand healthily.
......
After Wang Gude arranged the roasting of bamboo rats outside the door, he heard Huo Xiong's question when he came in, so he replied: "I have been in good condition for the past two days, and there is a small one who knocks his leg and is too naughty." β
"Well, it's better for you to be quiet here." Huo Xiong shook his head and sighed: "Four pigs over there have died, and the bamboo rats have also run away, and my head has grown in the past two days." β
Wang Gude smiled after hearing this: "It seems that we must strengthen management." β
"Yes, we need to do intensive training." Huo Xiong sighed: "There is a long way to go. β
Wang Goode agreed with the latter sentence, he stared at the calf scurrying in the fence in front of him, and said with the same point: "Yes, there is a long way to go." β
...... Generally speaking, livestock farming in ancient times was 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 concentrate on fattening livestock, so these pigs and cattle breeds with extremely fast growth in later generations did not reflect their advantages at all in ancient times.
However, after the reform, a large number of native populations in China began to become extinct, or walked on the road to extinction.
The characteristics of these native populations are very uniform: high fat percentages and slow growth.
There is no way, after thousands of years of artificial selection, the livestock with a high lean meat rate have been slaughtered, and there is no right to transmit offspring. However, grazing-free populations do not have the basic conditions for rapid growth.
What Wang Gude and the others are doing now is no different from those multinational animal husbandry companies in later generations: first expand the population, then slaughter all kinds of fast-growing livestock on the assembly line, and finally wipe out local populations such as local pigs and cattle.
Therefore, they have a long way to go in the future: to completely change the country's livestock structure, it is necessary to industrialize the cultivation of fodder, the industrialization of antibiotics, and the industrialization of livestock slaughter......
Approximately one generation is not enough.
......
After inspecting the cows and calves, Huo Xiong went to the stall of the two breeding bulls. Grumpy breeding bulls cannot be kept together, they are separated by high feed pens.
Seeing the tall and strong breeding cow weighing 1,200 kilograms eating corn stalks quietly, Huo Xiong laughed evilly, walked around the back of the bull's buttocks, and stretched out his hand to touch the pair of bowl-sized balls.
The bull was unsurprisingly angry, turned around and pushed his horns against it, shaking the thigh-thick railing.
"You kid just do it, that fool who was stabbed in the ass last time didn't seem to teach you a lesson?"
"Haha, I'm just going to see how energetic our breeding cattle are." Huo Xiong shook his hands and laughed: "Not bad, yes, the big guy has a big temper!" β
...... After inspecting the barn, it's time to eat the roasted bamboo rat.
Bamboo rat meat is a bit similar to the feeling of fish meat, and it is not greasy at all, so two people can easily get one by one.
"Okay, I'll keep one for tomorrow." After Wang Gude finished eating, he took the coffee pot and poured a cup for Huo Xiong with a full burp.
Huo Xiong didn't drink beer today. Even if the painting style is wrong, he and Wang Goode still drank coffee...... There's a reason for that, they still have a very important job to do, and they can't drink.
After a cup of coffee and a short rest, the two of them went to the second row of barns in the back.
This group of barns is full of buffalo, to be exact, female buffaloes. Nearly 200 healthy female buffaloes are housed in the back rows of barns.
In 17th-century southern China, the only cattle species that could be collected through the Crossing were the Chinese buffalo. These Chinese buffaloes are an important livestock resource due to their strong physique, resistance to ticks, tolerance to rough feeding, strong adaptability, and good service performance.
However, the purpose of collecting these female buffaloes is simple, not to cultivate the rice fields, but to borrow their stomachs...... Yes, these female buffaloes are used for surrogacy.
......
In the second decade of the 21st century, the development of science and technology can be expressed with each passing day; As a result of the rapid increase in information, any technology will quickly spread to human society.
Therefore, in later generations, embryo transfer, a technology that can rapidly expand the population, has become the standard for larger pastures.
Embryo transfer, as the name suggests, is the removal of a cow's fertilized egg from the body and the transfer of it into another cow's body.
This transplant is not the same as hybridization. The offspring produced by animal crossbreeding have both paternal and maternal genes, such as Simmental cattle and cattle crossbreeding, and the calves produced are "four dislikes", and both parents have characteristics.
The calves born to cows after embryo transfer are theoretically completely unrelated to the mother. Because the embryo is fertilized before it is transferred into the surrogate cow, the characteristics of the calf depend on the parties providing the fertilized egg, and it has nothing to do with the surrogate cow.
In fact, this technology is the ranch version of the famous IVF technology...... Humans "made" the first case of IVF in 1978; In 2011, a wealthy businessman in Guangzhou conceived octuplets with the help of IVF technology...... Awesome, right?
The matter is specific to the crossing of the people, what Huo Xiong wants to do today is to transplant a batch of embryos of purebred Simmental cattle into the body of a female buffalo.
In this way, after 280 days, the mother buffalo will give birth to purebred Simmental calves.
......
When Wang Goode was in Mexico, he would often go to the ranch next door to the US imperialist to do some business about embryo transfer, so he had enough technical reserves in this area.
Huo Xiong is not the same, he is quite clear about the steps of embryo transfer, but he has never done it, so today's operation is still based on Wang Goode.
The first thing the two of them had to do was to go to the ranch laboratory to thaw the embryos.
The embryos to be transferred are stored in refrigerated tanks with liquid nitrogen. These are freshly frozen embryos that Cao Chuan bought this morning from a large ranch in South America β there is a strict time limit for embryo transfer, so the two sides must be connected.
This is where embryo transfer comes in, because cows in heat don't wait for anyone.
You must know that in the period after Cao Chuan's accession to the throne, the import of materials from all walks of life has been stopped. The entire crossing country is now in a state of sideways consolidation, and it will not reopen until it has accumulated a certain amount of mobile import capacity.
