"Isn't that the rabbit? All of a sudden, it's cattle? " What director Mei is most concerned about is the technical problems, which can't be tightened any more.

He took the risk of investing money, painstakingly closed door to write applications, and risked being scolded to find the boss for what, not just for bovine embryo transfer? In the final analysis, no matter how good the rabbit is, it will not bring any profit to Zhongmu. However, 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. First he drank some water and moistened his throat. He said: "rabbit is a whole channel experiment, which starts from superovulation and ends all the way. There are many steps in this process, don't they need to wait? I asked them to start the step-by-step experiment of bovine embryos at the same time, that is, a single step, one by one, where is the difficulty, where the success rate is low, we can tackle the problem ahead of time. "

When he spoke, director Mei, director tie, director Qu, director Bai and other passers-by nodded convincingly.

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

At present, the best achievement of bovine embryo transfer carried out by the best research institute in China is half embryo transfer at room temperature. To put it bluntly, it is actually the completion of two steps: the first step, embryo segmentation, and the second step, embryo transfer.

The latter step is not worth the money. The key lies in the first step, which is the core technology mastered by domestic research institutes, and also the place where domestic research institutes keep ahead of veterinarians.

Now that Yang Rui has finished the embryo segmentation of cattle, he can officially announce that in the final field, he has also reached the first class in China.

If you think about it more deeply, you can also think that Yang Rui's laboratory was still playing with mice last month. Now we have copied the research results of mice to cattle. Is it far from the completion of embryo segmentation and frozen embryo transfer?

If you think about it like this, Yang Rui is a cash cow.

Yang Rui also showed a smile and said, "I also want to thank Zhongmu for providing the first sum of money, which enables us to carry out multiple experiments at the same time and greatly speeds up the progress."

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

"No, there is a big difference between sheep and cattle in terms of embryo transfer. If you want to verify the technology itself, you can use rabbits." Yang Rui casually said: "cattle and horses are both large animals. The commonly used schemes are non-surgical methods. Sheep can't do it. The volume is much smaller than cattle. New technologies need to be specially developed for it. The value of sheep is higher than rabbits and mice, and the gestation time is longer. In general, 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'll consider doing two or three more repeated experiments, and then doing superovulation and embryo transfer experiments at the same time."

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

Superovulation is to let cows superovulate. A normal Simmental cow will have an embryo and eventually develop into a calf. However, two or three or even three or four embryos can be obtained by using the method of over ovulation. Veterinarians take advantage of the time when the embryo just appears, and then hand it over to the laboratory for segmentation. Seven or eight half embryos can be obtained and then transferred, Equal to one or two months, the population size will be expanded seven or eight times, so repeatedly, in order to have large-scale breeding cattle.

Without such technology, it would be very difficult for large-scale pastures at home and abroad to accumulate millions of well bred cattle. Traditional animal husbandry powers such as the United States, northern Europe and Australia are better, and the rising stars with slight weaknesses should not be remembered.

Depending on the accumulation of one cow and two cows, the breeding of population is very slow. If we consider the problems of dystocia and premature death of calves, it is even more difficult to accumulate large population.

What's more terrible is that if an epidemic such as mad cow disease occurs, the death of millions of cattle caused by compulsory killing often means that decades of work is in vain.

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

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

China animal husbandry and other Chinese animal husbandry companies now value efficiency.

"Seize the day" is not to say. In the 1980s, a large number of people in China had enough to eat, and their desire for meat was even more terrifying. Even the officials in the pasture were no exception."How long do you expect... To take?" When director Mei asked, he was too nervous to know.

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

"Yes, we do. No guarantee." Director Mei does not know how many times he has said this.

"Our current progress is 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 the prediction I made before." Every time Yang Rui cuts a large piece of steak into his mouth, it's full of thick gravy.

The advantage of large steak lies in the sufficient preservation of gravy, which is one of the differences between Korean roast beef and steak. Full gravy is the reason why steak is expensive. Of course, there are many people who can't adapt to it, just like some people can't stand durian, which is a good taste to save money.

Yang Rui is very fond of the taste of big steak. If we say that beef is the motive force of his making money, it is at least three points true.

Now with the results of the experiment, he ate more delicious.

Director Mei looked at Yang Rui's delicious meat, but he was in a hurry. He looked at him and swallowed his mouth. He urged: "director Yang, what was your prediction before? You don't know what you're talking about. It's very urgent. "

"My previous prediction is that you will see the calf at the end of next year. Have you forgotten?" Yang Rui showed a look of astonishment.

Director Mei's face was full of ecstasy: "I guess it's this, but I can't believe it..."

There are people who don't know about it, and they are all looking forward to asking each other.

Although this technology will not be popularized immediately next year, this timetable has smashed the direction of all pastures.

Yang Rui laughs but does not say a word, sullen eat.

Pop!

Director Mei suddenly slapped the table and said in a high voice: "director Yang, your steak will be fully covered by Zhongmu in the future!"

Everyone was stunned for a moment, and in a flash, it was applause from the canteen.

Yang Rui made a rose red cut on the steak and said with a smile, "then I'll thank director Mei."

"You're welcome. You're welcome. Just a few pieces of beef." Director Mei smiles and glances at the Iron Rooster.

The director of the railway bureau is at ease.

It is called plain chicken for short.

"Zhongmu has a heart." Yang Rui said, but suddenly sighed.

"What's on Director Yang's mind?" Director Mei's smiling cooperation with Yang Rui.

Yang Rui put down his knife and fork again and said, "it's not a worry. However, with the research on embryo transfer of cattle, the place given by Haidian District is not suitable after all. It's better to have a ranch of your own. "
