"Isn't it just a rabbit? All of a sudden, it's a cow?" Director Mei is most concerned about technical issues, and he can't hold back anymore. Pen % fun % Pavilion www.biquge.info

He took the risk of throwing money, worked hard to write applications in retreat, and desperately risked being scolded to find the old man for something, isn't it just for the embryo transfer of cattle? In the final analysis, no matter how good the rabbit is, it can't bring a penny of income to the middle herd, but the embryo transfer of the cow, as long as it can be made, it is very powerful.

Yang Rui looked at the steak in front of him with some regret, first took a sip of water, moistened his throat, and said: "The rabbit is a full-channel experiment, that is, starting from the super-row and going all the way to the end." In this process, there are many steps that do not need to wait? I will let them start the step-by-step experiment of bovine embryos at the same time, that is, a single step, first look at one by one, where is the difficulty, where the success rate is low, and can be tackled in advance. ”

When he spoke, Director Mei, Director Tie, Director Qu Chang, Director Bai, and various passers-by nodded their heads in uniform.

Since you have invested money in this industry, you naturally have some understanding of this industry.

At present, the best result of cattle embryo transfer carried out by the best research institute in China is the half-embryo transfer at room temperature, to put it bluntly, it is actually completed two steps, the first step, embryo division, and the second step, embryo transfer.

The latter step is not worth much, the key lies in the first step, which is the core technology mastered by domestic research institutes, and it can be regarded as the place where domestic research institutes maintain a leading position over veterinarians.

Now, Yang Rui has completed the embryo division of the cow, and it can be officially announced that in the final field, he has also reached the domestic first-class.

If you want to go deeper, you can also think that Yang Rui's laboratory was still playing with mice last month, and now the research results of mice have been copied to the body of cattle, and the embryo segmentation is completed, is the frozen embryo transfer still far away?

Thinking like this, Yang Rui's whole body was like a cash cow with golden light.

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, which greatly accelerated the progress." ”

"You're welcome, you're welcome. Director Mei shook his head again and again, and said with a smile: "I thought that when the rabbit was done, he would make a little bit of large and medium-sized animals such as sheep first, don't you need it?"

"No, in terms of embryo transfer, there is a big difference between sheep and cattle, and if you want to verify the technology itself, you can use rabbits. Yang Rui casually introduced: "Cattle and horses, are relatively large animals, the commonly used scheme is non-surgical, sheep is not good, the volume is much smaller than cattle, need to develop new technology for it, the value of sheep is higher than rabbits and mice, the gestation time is long, in vain increase the cost of experiments, in general, 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 thinking about doing two or three more repeat tests, and then doing the tests of superarrangement and embryo transfer at the same time." ”

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

Superovulation is the overovulation of a cow. Excess eggs, in order to get an excess of embryos, normal Simmental cattle will have an embryo, and eventually develop into calves, but the use of excessive ovulation, often can get two or three, or even three or four embryos, veterinarians take advantage of the embryo just appeared, and then handed over to the laboratory for segmentation, you can get seven or eight half embryos, and then transfer, equal to one or two months, the size of the population will be expanded seven or eight times, so repeatedly, in order to have a large-scale breed of cattle born.

If it were not for such technology, it would be difficult for large-scale pastures at home and abroad to accumulate millions of high-quality cattle. Traditional livestock powerhouses such as the United States, Northern Europe and Australia are better, and the rising stars with a slight weakness are basically not to be remembered.

Relying on the accumulation of one cow and two cows, the cultivation of the population is very slow, and if you take into account the problems of dystocia and calf death, it is even more difficult to accumulate a large population.

What's even more frightening is that in the event of an epidemic such as mad cow disease, the death of millions of cattle caused by forced extermination 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 convert the money directly into the herd is not something that everyone can afford.

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

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

"Seize the day" is not to say, in the 80s, people were a large number of well-fed people in China, and their craving for meat was even more intense and terrifying, even for ranch officials.

"Expected...... How long will it take?" asked Director Mei, who was nervous and 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 understood, no tickets. "I don't know how many times I have said this.

"We're making progress faster than I expected. Yang Rui said that he began to bow his head to deal with the steak.

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

"That's what I predicted. Yang Rui cut a large piece of steak every time and stuffed it into his mouth, which was full of thick gravy.

The advantage of large steak is that the gravy is fully retained, which is also one of the differences between Korean roast beef and steak.

Yang Rui likes the taste of big steak very much, and if you want to say that the driving force behind his money is beef, at least three points are true.

Now that the experiment has come to fruition, he eats even more deliciously.

Director Mei watched Yang Rui eat meat so deliciously, he was in a hurry, watching him swallow a mouthful, he also swallowed his saliva, and urged: "Director Yang, what kind of prediction did you say before? ”

"My previous prediction was to let you see the calf at the end of next year, did you forget?" Yang Rui showed a stunned expression.

Director Mei had a look of ecstasy on his face: "I guess it's this, but I'm a little afraid to believe it......"

There are people who don't know about this, and they even ask each other with their eyebrows.

Although this technology will not be widely available immediately next year, this timetable will still shatter the direction of all ranches at once.

Yang Rui smiled but did not speak, and ate with a dull head.

Syllable!

Director Mei suddenly slapped the table and said loudly: "Director Yang, your steak, we are the middle herd, and it will be all covered in the future!"

Everyone was stunned for a moment, and in an instant, the cafeteria burst into applause.

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, just a few pieces of beef. Director Mei smiled and glanced at the iron rooster.

The iron bureau is safe and secure.

Abbreviated as vegetarian chicken.

"The middle pastor has a heart. Yang Rui said but suddenly sighed.

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

Yang Rui put down the knife and fork again and said, "It's not a matter of concern, but with the development of the research on embryo transfer of cattle, the place given by Haidian District is not suitable after all." It's better to have a piece of your own pasture as well. ”
