Rebirth of the God-level Xueba

"Didn't you just make it into a rabbit? You're going to be a cow right away?" Director Mei is most concerned about technical issues, and now he can't hold back any longer.

He took the risk to invest money, worked hard to write the application in retreat, and risked being scolded to find the boss. Why, isn't it just for the embryo transfer of cattle? In the final analysis, no matter how good the rabbit is, it cannot bring China Animal Husbandry a penny of income, but as long as the embryo transfer of cattle can be done, it will be very powerful.

Yang Rui looked at the steak in front of him with some regret. He drank some water to moisten his throat, and said, "The rabbit is an all-channel experiment, starting from the super row and going all the way to the end. In this process, there are many steps. Don't you need to wait? I asked them to start the step-by-step experiment on bovine embryos at the same time, that is, individual steps, first look at them one by one, where are the difficulties, where the success rate is low, and can be tackled in advance."

When he was talking, Director Mei, Director Tie, Director Qu, Director Bai, and various passers-by A, B, C, D all nodded in agreement.

Since everyone has invested money in this business, they naturally have some understanding of this business.

At present, the best result of bovine embryo transfer performed by the best research institutes in China is semi-embryo transfer at room temperature. To put it bluntly, two steps have been completed. transplant.

The latter step is worthless, the key lies in the first step, which can be regarded as the core technology mastered by domestic research institutes, and it can also be regarded as the place where domestic research institutes keep ahead of veterinarians.

Now that Yang Rui has completed the division of cow embryos, he can officially announce that he has also reached the top level in the country in the final field.

If you want to go deeper, you can also think that Yang Rui's laboratory was still playing with mice last month, and now it has copied the research results of mice to cows. After the embryo segmentation is completed, is it still far away for frozen embryo transfer?

Thinking about it this way, Yang Rui's whole body looks like a golden radiance - a cash cow.

Yang Rui also smiled and said: "I would also like to thank Zhongmu for providing the first fund, which allowed us to conduct multiple experiments at the same time, greatly speeding up the progress."

"You're welcome, you're welcome." Mei Ju shook his head again and again, and said with a smile, "I thought that after the rabbit was finished, I would first make some large and medium-sized animals like sheep, don't you need it?"

"No need. In terms of embryo transfer, there is a big difference between sheep and cows. To verify the technology itself, rabbits are enough." Yang Rui casually introduced: "Both cows and horses are relatively large animals. The commonly used method They are all non-surgical methods, but sheep will not work. They are much smaller than cows, and new technologies need to be specially developed for them. The value of sheep is higher than that of rabbits and mice, and the pregnancy time is longer, which will increase the cost of experiments in vain. Said that it is not suitable for verification."

Several people nodded again, they didn't care what Yang Rui said, anyway, Yang Rui was right.

"If the segmentation experiment is successful, the next step is embryo transfer?" Director Mei is still concerned about the progress.

Yang Rui nodded and said, "I'm considering doing two or three more repeated experiments, and then doing superovulation and embryo transfer at the same time."

"There is no problem with embryo transfer, and superovulation should be simple, mainly because of reagents and toxicity." Ouyang Shi followed Yang Rui's words and explained.

Superovulation is the process of allowing a cow to ovulate in excess. Excess eggs can produce excess embryos. Normal Simmental cattle will have one embryo, which will eventually develop into a calf. However, with excess ovulation, two or three, or even three or four embryos can often be obtained. , the veterinarian takes the embryos when they just appear, and then sends them to the laboratory for division, and then they can get seven or eight semi-embryos, and then transplant them. It takes one or two months to expand the population size by seven or eight times. Repeatedly, just can have large-scale breeding cattle to be born.

Without such technology, it would be difficult for large ranches at home and abroad to accumulate millions of fine-bred cattle. The traditional animal husbandry powerhouses such as the United States, Northern Europe and Australia are better, and the rising stars who are slightly weaker are basically not to be remembered.

Relying on the accumulation of one cow and two cows, the breeding of the population is very slow. If you consider the problems of dystocia and calf death, it will be even more difficult to accumulate a large population.

What is even more frightening is that in the event of an epidemic like mad cow disease, the forced slaughter of millions of cattle often means that decades of work have been wasted.

This kind of pressure will drive all farmers crazy - there are many rich farmers or livestock companies, but the time and energy required to directly convert money into cattle is not everyone can afford it.

The value of cattle embryo transfer, or in other words, the value of all science, is reflected in the improvement of efficiency.

China's animal husbandry companies such as China Animal Husbandry now value efficiency.

"Seize the day and night" is not just talking. People in the 1980s were a large number of people in China who had enough to eat, and their desire for meat was even more intense and frightening, even officials in the ranch were no exception. .

"Estimated... how long will it take?" When Director Mei asked, he was so nervous that he didn't know.

Yang Rui thought for a while and said, "I have a timetable here, but I can't guarantee it. It's just a reference..."

"Understood, we understand, no guarantee." Director Mei did not know how many times he said this.

"Our current progress is faster than I expected." Yang Rui said and began to bow his head to deal with the steak.

Director Mei was impatient and urged, "What time do you expect?"

"It's the prediction I made before." Yang Rui cut a large piece of steak every time and stuffed it into his mouth, full of thick gravy.

The advantage of a large steak is that the gravy is fully preserved. This is also one of the differences between Korean roast beef and steak. The full gravy is the reason why steak is expensive. Of course, there are many people who cannot adapt, just like some People can't stand durian, it's a good taste to save money.

Yang Rui likes the taste of big steaks very much. If he said that beef is the driving force behind his money, it is at least a third of the truth.

Now that the experiment has yielded results, the food he eats is even more delicious.

Director Mei looked at Yang Rui eating meat so deliciously, he was in a hurry, watched him swallow, swallowed his saliva, and urged: "Director Yang, what kind of prediction are you talking about before?" Huh? You didn’t speak clearly, you’re really anxious to death.”

"My previous prediction was that you will see the calf at the end of next year, have you forgotten?" Yang Rui showed a stunned expression.

Director Mei had an ecstatic expression on his face: "I guess it's this, but I can't believe it..."

Those who didn't know about it asked each other happily.

Although this technology will not be popularized immediately next year, this timetable still shatters the direction of all pastures at once.

Yang Rui smiled without saying a word, enjoying his meal in suspense.

Snapped!

Director Mei suddenly slapped the table, and said loudly: "Director Yang, our Zhongmu will take care of your steak from now on!"

Everyone was stunned for a moment, and in an instant there was applause from the cafeteria.

Yang Rui made a rose-red incision on the steak, and said with a smile: "Then I will thank Director Mei."

"You're welcome, you're welcome, it's just a few pieces of beef." Director Mei smiled and glanced at the iron rooster.

The chief of the iron bureau is as calm as he is.

It is called vegetarian chicken for short.

"Zhongmu has a heart." Yang Rui sighed suddenly while speaking.

"Director Yang has something on his mind?" Director Mei cooperated with Yang Rui with a smile on his face.

Yang Rui put down his knife and fork again, and said, "It's nothing to worry about. However, with the development of cattle embryo transplantation, the land given by Haidian District is not suitable after all. It's better to have a pasture of our own."
